Everything about cholesterol: normal blood levels, tips and recommendations on how to reduce it. Ways to normalize LDL levels
Hearing about cholesterol, a person immediately thinks about its harm. This is true, but with a slight clarification: the body needs this substance for normal functioning. It’s just that its useful amount has its limits.
Cholesterol, a naturally occurring fatty (lipophilic) alcohol, is an organic compound found in the outer layer of every cell. human body. Cholesterol is responsible for performing a number of essential functions for the body, including:
- strengthening of cell walls;
- production of bile acid, which breaks down fats in the intestines;
- participation in the synthesis of vitamin D and sex hormones - testosterone, cortisol and estrogen.
Cholesterol is also found in mother's milk, due to which the walls of the baby’s brain cells become stronger.
In total, the body produces about 500 milligrams of cholesterol. Its main part is formed in the liver. The body receives approximately the same amount of this substance through whole foods.
Cholesterol does not dissolve well in water. That is why in pure form it is not transported by the bloodstream to body tissues. Cholesterol and transporter proteins form complex compounds - lipoproteins. They are highly soluble and can be transported in the blood.
Depending on the amount of lipids they contain, these compounds are:
- very low density - VLDL (LP here means lipoproteins);
- low density (LDL);
- high density (HDL);
- chylomicrons.
LDL is called “bad” cholesterol because it often forms plaques on the walls of blood vessels. But HDL is the “good” one, which resolves these plaques. The above classification is conditional, since cholesterol is always the same in structure and composition. What matters is which transporter protein it is attached to.
Well, in a certain amount, condition and ratio, cholesterol is absolutely harmless and vital for the body. You just need to try to control its level.
Deciphering a blood test for cholesterol
A blood test called a lipid profile helps determine cholesterol levels. It records not only the indicator total cholesterol(OX), but also its other types (including HDL, LDL and triglycerides).
The unit of measurement for cholesterol levels is millimoles per liter of blood (mmol?/? liter).
For each indicator there are 2 values – minimum and maximum.
The norms are not the same, and their size depends on age and gender.
There is no exact indicator that the amount of cholesterol should normally be equal to. However, there are recommendations as to what range its level should be in a given period of life in a healthy person. These indicators differ between men and women.
Exceeding this range often indicates the presence of a disease. If cholesterol levels increase, hypercholesterolemia occurs. Its presence indicates the risk of rapid development of atherosclerosis. Hypercholesterolemia can be caused by hereditary pathology, but most often it appears due to abuse fatty foods.
TC level indicators (on a lipid profile) are considered normal if it is in the range of 3.11–5.0 mmol/liter.
A level of “bad” cholesterol (LDL) above 4.91 mmol/liter is a sure sign of atherosclerosis. It is desirable that this indicator does not exceed the range from 4.11 to 4.91 mmol/liter.
A low HDL level also indicates that the human body is affected by atherosclerosis. A level of at least one millimole per liter of blood is considered normal.
Triglyceride (TG) levels are also important. If it is higher than 2.29 mmol/liter, then this may indicate the presence of various diseases, including:
- IHD (coronary heart disease);
- pancreatitis;
- diabetes mellitus;
- hypothyroidism;
- hepatitis and cirrhosis of the liver;
- hypertension;
- obesity;
- gout
An increase in TG also occurs when pregnancy occurs, oral contraceptives or hormonal drugs are used.
But low TG levels can be caused by poor diet, kidney tissue damage, chronic lung problems, and hyperthyroidism.
Based on the lipid profile, the atherogenicity coefficient (index) (Ia) is calculated. It shows how high the likelihood of developing vascular and heart diseases is. It is calculated using the formula:
A coefficient below three means that the amount of “good” cholesterol in a person’s blood is quite sufficient to minimize the risk of atherosclerosis.
An indicator value ranging from three to four (with an upper limit of 4.5) indicates a high risk of developing the disease or even its presence.
The coefficient goes beyond the norm with very high probability means the presence of a disease.
To do the analysis, a sample is taken venous blood in the morning on an empty stomach. Food should be consumed at least six to eight hours before the procedure. In addition, physical activity and fatty foods are contraindicated.
Cholesterol standards for men
Cholesterol guidelines change every five years. In childhood, only the general indicator is measured. After reaching the age of five, both “good” and “bad” cholesterol are recorded. The limiting norms of a substance in the body increase over time. This happens up to the age of fifty: then cholesterol levels decrease.
The average cholesterol levels are:
- total cholesterol – from 3.61 to 5.21 mmol/liter;
- LDL – from 2.250 to 4.820 mmol/liter;
- HDL – from 0.71 to 1.71.
Table 1 contains information about the boundary values of the indicator in the most productive time of a man’s life: from fifteen years to fifty.
An increase in cholesterol levels should certainly be of great concern. Its consumption per day should not exceed three hundred grams. In order not to exceed this norm, you must adhere to the following diet:
- Eat only lean meat and dairy products (low-fat).
- Replace butter with vegetable oil.
- Do not eat fried or spicy foods.
- Eat as many fruits as possible. Citrus fruits in particular are very beneficial. For example, grapefruit is particularly effective in lowering cholesterol levels. If you eat it every day, then after a few months this figure can be reduced by almost eight percent.
- Include legumes and oatmeal in your diet - they will help reduce cholesterol.
- Stop smoking. Smoke lovers gradually accumulate “bad” cholesterol in their bodies and waste “good” cholesterol. Smoking day after day damages the walls of blood vessels, on which this harmful substance begins to accumulate.
- Exclude alcoholic drinks and reduce your coffee consumption.
In general, if you adhere to a proper and balanced diet, you can achieve a reduction in cholesterol by fifteen percent.
Cholesterol standards for women
As noted above, cholesterol levels vary by gender and age and change throughout life. Health status is also important. Female norm below masculine.
Average cholesterol levels are shown in Table 2.
Total cholesterol, high (“good”) and low (“bad”) densities are assessed.
If total cholesterol is within normal limits and LDL is elevated, an increase in blood thickness may occur. This is dangerous due to the high probability of blood clots forming inside blood vessels.
The level of “bad” cholesterol should not exceed 5.590 mmol/liter, otherwise there will be a threat to life. When the total indicator exceeds 7.84 mmol/liter, in circulatory system pathologies begin to develop.
A drop in “good” cholesterol below normal is undesirable. After all, then the body will feel its deficiency and there will be a threat of formation blood clots in vessels.
Metabolism in a young body occurs much faster, and therefore the younger the woman, the closer to normal her cholesterol level is. Until a certain time, excess does not accumulate in the blood, but heavy products food (including fatty and spicy foods) are easier to digest.
However, cholesterol also increases in youth if the following diseases are present:
- diabetes;
- liver failure;
- disruptions in the functioning of the endocrine system.
Cholesterol levels that are considered normal are shown in Table 3.
Cholesterol levels increase slightly in females, have crossed the 30-year mark(Table 4).
The likelihood of an increase in cholesterol levels is greater in those women who are partial to smoking and take contraceptives in the form of pills. After 30, nutrition becomes more important. After all, in your fourth decade, metabolic processes no longer occur so quickly. The body needs significantly less carbohydrates and fats, and it is more difficult for it to process foods that contain these substances. As a result, their excess accumulates, which provokes an increase in cholesterol in the blood. This, in turn, leads to a deterioration in heart function.
After 40 In women, reproductive function gradually fades, sex hormones (estrogens) are produced in smaller quantities. But they are the ones who protect the woman’s body from possible jumps in cholesterol levels.
After forty-five, menopause approaches. Estrogen levels drop rapidly. There is an increase in cholesterol, the reason for which is physiological characteristics female body.
Just like men, women should pay special attention to their diet. You need to be very careful when eating eggs, dairy products, and meat. It is recommended to eat more sea fish, including fatty ones. Vegetables and fruits should form the basis of your daily diet. Those women who suffer from extra pounds, move little and cannot give up cigarettes should be especially attentive to themselves.
Cholesterol after 50 years in men
Visually without carrying out necessary tests It is impossible to determine the increase in cholesterol. However, after reaching the age of fifty, men may develop characteristic symptoms, including:
- angina pectoris, that is, narrowing of the coronary heart arteries;
- the appearance of skin tumors with fatty inclusions inside near the eyes;
- pain in the legs with little physical activity;
- mini-strokes;
- heart failure, shortness of breath.
After fifty, men enter a life-threatening period. Therefore, they simply must monitor their cholesterol levels. Its norms are:
- 51–55 years: TC – 4.08–7.16/ LDL – 2.30–5.110/ HDL – 0.721–1.631;
- 56–60 years: TC – 4.03–7.14/ LDL – 2.29–5.270/ HDL – 0.721–1.841;
- 61–70 years: TC – 4.08–7.09/ LDL – 2.55–5.450/ HDL – 0.781–1.941;
- 71 and above: TC – 3.72–6.85/ LDL – 2.491–5.341/ HDL – 0.781–1.941.
Cholesterol after 50 years in women
After fifty, it is normal for total cholesterol levels to increase. In this case, special attention should be paid to the LDL value.
Cholesterol levels in mature and elderly women are as follows:
As can be seen from the table, the range within which the normal cholesterol level is located is very large. However, you should not allow the established limits to be exceeded.
In older women who are over sixty years old, the concentration of total cholesterol in the blood can reach 7.691 mmol/liter. It would be nice to stay at this figure until the age of 70, although a slight increase (up to 7.81 mmol/l) is allowed.
“Good” cholesterol should not fall below 0.961, and “bad” cholesterol should not rise above 5.71.
IN advanced age – after seventy years
There is a widespread misconception that cholesterol is harmful to the body, and its level in the blood is one of the most important indicators of human health. Many people, in an attempt to maintain their health, adhere to strict diets, eliminating all foods containing cholesterol. However, few people know that it is part of cell membranes, gives them strength and ensures the exchange of substances between the cell and the intercellular substance and regulates the activity of enzymes. Thus, without cholesterol, the normal functioning of our body is impossible.
Despite the importance of cholesterol, excessive consumption Fatty foods of animal origin can lead to increased levels in the body, which negatively affects health and can cause serious illness.
Controlling your cholesterol levels will help keep you healthy long years, increase the body’s natural resistance, increase life expectancy and improve its quality. In this article we will dispel the most common myths about the role of cholesterol in our body and its metabolism. We will also look at the most effective ways control cholesterol levels.
Cholesterol (from the Greek chole - bile and stereo - solid, hard) was first identified in gallstones This is where it got its name. It is a natural, water-insoluble lipophilic alcohol. About 80% of cholesterol is synthesized in the body (liver, intestines, kidneys, adrenal glands, gonads), the remaining 20% must come from the food we consume.
Circulating in the bloodstream, cholesterol is used, if necessary, as a building material, as well as for the synthesis of more complex compounds. Since it is insoluble in water (and, accordingly, in the blood), its transportation is possible only in the form of complex water-soluble compounds, which are divided into 2 types:
Low-density lipoproteins (LDL)
Lipoproteins high density(HDL)
Both of these substances must be in a strictly defined ratio, and their total volume must also not exceed the norm. This can lead to serious illness of cardio-vascular system.
Functions of cholesterol in the body:
— ensuring the strength of cell walls, regulating their permeability to various molecules;
— synthesis of vitamin D;
- synthesis by the adrenal glands of steroid (cortisone, hydrocortisone), male (androgens) and female (estrogens, progesterone) sex hormones;
- as bile acids participates in the formation of bile and the absorption of fats during digestion;
- participates in the formation of new synapses in the brain, thereby improving mental abilities and memory.
In fact, it is not cholesterol as such that causes harm, but its fluctuations outside the normal range. Health problems can be caused by both excess and lack of it in the body.
Negative effects of cholesterol
According to statistics, people who die from cardiovascular diseases low levels of high-density lipoprotein but high levels of low-density lipoprotein were observed.
Lipoproteins, if their ratio is incorrect or if their content in the blood is prolonged for a long time, can settle on the walls of blood vessels and cause atherosclerosis.
This dangerous disease occurs when plaques form on the endothelium of blood vessels, which over time grow more and more and accumulate calcium. As a result, the lumen of the vessels narrows, they lose elasticity (stenosis), this leads to a decrease in the supply of oxygen and nutrients to the heart and tissues and the development of angina pectoris (cessation of arterial blood flow to certain parts of the heart due to blockage coronary artery, accompanied by pain and discomfort in the chest). Often it is due to a violation of the blood supply that it occurs heart attack or myocardial infarction. The formation of cholesterol plaques leads to damage to the inner wall of blood vessels; a blood clot can form, which can subsequently block the artery or break off and cause an embolism. Also, a vessel that has lost elasticity can burst when pressure in the bloodstream increases.
The role of lipoproteins
HDL is considered a “good” lipoprotein due to its ability to dissolve cholesterol plaques and remove it from artery walls; the higher its percentage relative to LDL (“bad” lipoprotein), the better. LDL transports cholesterol from the organs that synthesize it into the arteries, and when the content of this compound is elevated, these large insoluble molecules aggregate in the form of fatty plaques, attach to the vessels and clog them. Having been exposed oxidative processes, cholesterol loses its stability and can easily penetrate into the thickness of the artery walls.
Specific antibodies begin to be produced in large quantities against the resulting oxidized LDL, which leads to severe damage artery walls. In addition, cholesterol helps reduce nitric oxide levels, increasing the risk of developing cardiovascular diseases.
Nitric oxide plays important role in organism:
— dilates blood vessels, lowers blood pressure, prevents the formation of blood clots in the bloodstream;
- plays an important role in the fight against bacteria and viruses that enter the body, destroys cancer cells;
- increases endurance muscle tissue;
- participates in the exchange of information between different cells, is a neurotransmitter at synapses.
HDL not only removes cholesterol from the blood back to the liver, but also prevents the oxidation of LDL.
Signs of increased cholesterol levels in the body
Increased cholesterol levels are associated with impaired lipid (fat) metabolism. This may be a symptom not only of atherosclerosis, but also of other serious illnesses:
- liver;
— kidneys (chronic renal failure, glomerulonephritis);
- pancreas ( chronic pancreatitis);
- diabetes mellitus (a serious disease associated with impaired synthesis of the islets of Langerhans by beta cells in the pancreas);
- hypothyroidism (decreased hormone synthesis thyroid gland);
- obesity.
Symptoms of atherosclerosis are caused by narrowing of the lumen of blood vessels as a result of prolonged and persistent elevated cholesterol levels, and deterioration of blood circulation by different areas bloodstream.
Main symptoms:
- angina pectoris (sudden discomfort or painful sensations in the chest, occurring during physical activity or emotional stress);
- shortness of breath;
- arrhythmia (violation heart rate);
- cyanosis and swelling of peripheral parts of the body (fingers, toes);
- periodic leg cramps (intermittent claudication);
- memory impairment, inattention;
— reduction intellectual abilities;
- yellow-pink lipid deposits in the skin (xanthomas), most often observed on the skin of the eyelids and in the ankle joints.
The impact of HDL and LDL levels on our health
Still, the opinion that the general level HDL lipoproteins and LDL affects the state of health and their increase entails horrible consequences for the functioning of the whole body. However, this statement is not entirely true. Yes, the above diseases will be accompanied by an increased content of lipoproteins in general, but what is much more important is the exact ratio of “good” HDL and “bad” LDL in the blood. It is the violation of this proportion that leads to health problems. When determining the content of lipoproteins in the blood, 4 indicators are taken into account: the total amount of cholesterol, HDL level, LDL and triglycerides.
Norms
Total cholesterol in the blood - 3.0 - 5.0 mmol/l;
With the threat of atherosclerosis, total cholesterol rises to 7.8 mmol/l;
LDL at men- 2.25 - 4.82 mmol/l;
LDL in women- 1.92 - 4.51 mmol/l;
HDL at men- 0.72 - 1.73 mmol/l;
HDL at women- 0.86 - 2.28 mmol/l;
Triglyceridesin men- 0.52 - 3.7 mmol/l;
Triglyceridesamong women- 0.41 - 2.96 mmol/l.
The most indicative is the ratio of HDL and LDL against the background of total cholesterol levels. In a healthy body, HDL is much higher than LDL.
The most effective treatments for high cholesterol
There are many drugs that lower cholesterol levels in cases where this indicator creates serious threat health, or already at the beginning of the development of atherosclerosis. It is necessary to pay tribute, an important part of which is proper nutrition. In such cases, diet and moderate physical activity will help not only bring all blood counts back to normal, but will also completely heal and rejuvenate your body.
For a faster therapeutic effect, use pharmacological preparations:
— Statins- the most popular drugs, the principle of their action is to inhibit the synthesis of cholesterol in the liver by blocking the corresponding enzymes. They are usually taken once a day before bed (at this time the active production of cholesterol in the body begins). Therapeutic effect occurs after 1-2 weeks of systematic use; with long-term use they are not addictive. Side effects may include nausea, abdominal and muscle pain, and in rare cases there may be individual sensitivity. Drugs of the statin group can reduce cholesterol levels by 60%, but if they are taken for a long time, it is necessary to regularly take tests for AST and ALT every six months. The most common statins are cerivastatin, fluvastatin, lovastatin.
— Fibrates stimulate the production of HDL, recommended for triglyceride levels of 4.5 mmol/l. It is highly not recommended to use it with statins. Side effects appear as gastrointestinal disorders, flatulence, nausea, vomiting, abdominal pain. Representatives of this group of drugs: clofibrate, fenofibrate, gemfibrozil.
— Bile acid sequestrants. This group of drugs is not absorbed into the blood, but acts locally - it binds to bile acids, which are synthesized from cholesterol, and removes them from the body naturally. The liver begins to increase the production of bile acids, using more cholesterol from the blood, visible positive effect occurs a month after starting medication; simultaneous use of statins is possible to enhance the effect. Long-term use medications can lead to impaired absorption of fats and vitamins, and increased bleeding is possible. Side effects: flatulence, constipation. These drugs include: colestipol, cholestyramine.
— Cholesterol absorption inhibitors interfere with the absorption of lipids from the intestine. Drugs in this group can be prescribed to people who have contraindications to taking statins, since they are not absorbed into the blood. In Russia, only 1 drug from the group of cholesterol absorption inhibitors is registered - ezetrol.
The above measures are used in advanced cases, when it is necessary to quickly reduce cholesterol levels, and lifestyle changes cannot quickly produce the desired effect. But even when taking pharmacological agents Don’t forget about prevention and harmless natural supplements that, with long-term regular use, will help you prevent cardiovascular diseases in the future.
Folk remedies that help lower blood cholesterol levels
— Niacin ( a nicotinic acid, vitamin PP, vitamin B 3). The mechanism of action has not been fully studied, but experiments show that after just a few days of taking increased doses of the vitamin, the level of LDL and triglycerides in the blood decreases noticeably, but the amount of HDL increases up to 30%. Unfortunately, it does not reduce the risk of developing cardiovascular complications and seizures. For maximum effectiveness, you can combine niacin with other treatment methods.
— . Contained in fish oil and seafood, as well as in cold-pressed (unrefined) vegetable oils. They have a positive impact on nervous system, prevent rickets during the period active growth, help reduce cholesterol and blood pressure, improve blood circulation, strengthen blood vessels and give them elasticity, prevent their thrombosis, and participate in the synthesis of hormone-like substances - prostaglandins. Regular intake of sources of essential fatty acids will have a miraculous effect on the functioning of the entire body, in particular, it will help prevent the development of atherosclerosis.
— Vitamin E. Extremely strong antioxidant, prevents the breakdown of LDL and the formation of fatty plaques. For a positive effect to occur, it is necessary to constantly consume the vitamin in appropriate doses.
— Green tea contains polyphenols - substances that affect lipid metabolism, they reduce the level of “bad” cholesterol and increase the content of “good” cholesterol. In addition, tea contains antioxidants.
- Garlic. Fresh garlic is recommended to be consumed to reduce cholesterol levels and prevent the formation of clots in blood vessels (thin the blood). The active components of garlic are sulfur-containing compounds, in particular alliin.
— Soy protein. They are similar in action to estrogens - they reduce the likelihood of atherosclerosis. Genistein prevents the oxidation of LDL due to its antioxidant properties. In addition, soy stimulates the production of bile, thereby helping to remove cholesterol from the body.
— Vitamins B 6 (pyridoxine), B 9 ( folic acid), B 12 (cyanocobalamin). A sufficient amount of these vitamins in the diet contributes to the proper functioning of the heart muscle and significantly reduces the risk of developing atherosclerosis and coronary heart disease.
What factors contribute to increased cholesterol levels and the development of atherosclerosis?
Most often, atherosclerosis affects people who have neglected their health for a long time. The sooner you change your lifestyle, the less likely you are to develop serious illnesses. Here are 4 main factors that contribute to high blood cholesterol:
— Passive lifestyle. With low mobility and lack of physical activity, the level of “bad” cholesterol increases, creating a threat of developing cardiovascular diseases.
— Obesity. Lipid metabolism disorders are closely related to high content cholesterol. People who are overweight are prone to various diseases of the cardiovascular system.
— Smoking. Leads to narrowing of arteries, increased blood viscosity, thrombosis, and entails a risk of heart disease.
— Consumption of fatty animal products V large quantities leads to an increase in LDL.
— Heredity. The predisposition to high cholesterol levels is genetically transmitted. Therefore, people whose relatives suffer from this pathology should carefully monitor their health.
A healthy lifestyle as a method of combating cholesterol
As you maintain a healthy diet and an active lifestyle, your risk of developing various diseases decreases. This especially applies to people at risk. By changing your lifestyle, you improve the functioning of the whole organism, even despite the tendency to any pathologies, internal defense mechanisms can easily cope with the threat.
Active sports improve metabolism, train the heart muscle at the same time as skeletal muscles, promote better blood supply to all organs and systems (during physical activity, blood from the depot goes into the general channel, this contributes to better saturation of organs with oxygen and nutrients).
Sports exercises also lead to strengthening the walls of blood vessels and prevent the development varicose veins veins
Don't forget the importance of proper nutrition. Should not be abused strict diets. The body must receive everything it needs nutrients in optimal proportions, vitamins and minerals, fiber. The diet should contain sufficient quantity vegetables, fruits, cereals, lean meat, sea and ocean fish, vegetable unrefined oils, milk and dairy products. If there is a lack of any vitamins in the diet, it is worth periodically taking medications containing them to prevent vitamin deficiencies.
Quitting smoking will reduce the risk of developing not only atherosclerosis, but also a number of other diseases, such as bronchitis, stomach ulcers, and cancer.
Sports – the best remedy against stress and depression, it strengthens the nervous system. Regular physical activity, be it a jog in the park or 3 hours of exercise in gym, helps relieve the negativity and irritation accumulated throughout the day; many athletes experience euphoria during training. It has been experimentally proven that active people are much less stressed than those who lead a sedentary lifestyle.
Conclusion
As you can already see, cholesterol is an extremely important compound that performs a number of vital functions. important functions. It is necessary for our life, but its amount in the body should not exceed normal limits. An imbalance in the ratio of high- and low-density lipoproteins entails serious consequences.
The best way to treat is timely prevention. The most effective method Preventing high blood cholesterol levels is a healthy lifestyle.
When you give up bad habits and start adhering to the above rules, you will completely forget about your health problems.
Cholesterol. Myths and deception.
The normal functioning of your body depends on how stable your blood sugar levels are. When we eat sugar or carbohydrates, the body converts them into glucose. Our body uses it as energy to provide various functions, starting from the work of neurons or nerve cells in the brain, ending with processes occurring at the cellular level.
What is sugar level
Blood sugar is the amount of glucose in your blood. The value of glucose (sugar - hereinafter) in the blood is most often measured in millimoles per liter or milligrams per deciliter. For humans, normal blood sugar ranges from 3.6 mmol/L (65 mg/dL) to 5.8 mmol/L (105 mg/dL). Of course, the exact meaning is individual for everyone.
How the body controls blood sugar levels
It is very important that your sugar levels are normal. It should not be allowed to be a little higher or a little lower, if it falls too much and goes beyond the normal range, the consequences can be very serious, such as:
- Confusion, loss of consciousness and subsequent coma.
- If your blood sugar is high, your vision may become dark and blurry, and you will feel very tired.
Principles of regulation
| Sugar level | Effects on the pancreas | Effects on the liver | Effect on glucose levels |
|---|---|---|---|
| High | This sugar level gives a signal to the pancreas to produce insulin. | The liver converts any excess glucose into glucagon. | Sugar levels drop. |
| Short | Low levels signal the pancreas to stop producing insulin before it is needed again. At the same time, glucagon is released. | The liver stops processing excess glucose into glucagon due to its release from the pancreas. | Sugar levels are rising. |
| Normal | When you eat, glucose enters the bloodstream and signals the pancreas to release insulin. This helps glucose enter the cells and give them the energy they need. | The liver is at rest, not producing anything, since sugar levels are normal. | Sugar levels are normal and stay the same. |
If the sugar level is between 3.6 and 5.8 mmol/l or 65 and 105 mg/dl, then this is said to be the normal blood sugar level of a healthy person.
To maintain normal blood sugar, our pancreas produces two different hormones that maintain it at the desired level - insulin and glucagon (a polypeptide hormone).
Insulin
Insulin is a hormone produced by pancreatic cells that is released in response to glucose. Insulin is needed by most cells in our body, including: fat cells, muscle, liver cells. This is a protein (protein), which consists of 51 types of amino acids and performs the following functions:
- Tells muscle and liver cells to accumulate converted glucose in the form of glucogen.
- Helps fat cells generate fat by converting glycerol and fatty acids.
- Instructs the kidneys and liver to stop producing their own glucose through a metabolic process (gluconeogenesis).
- Stimulates muscle and liver cells to produce protein from amino acids.
To summarize the above, we can conclude that insulin helps the body absorb nutrients after meals, lowering blood sugar, amino acids and fatty acids.
Glucagon
Glucagon is a protein produced by alpha cells. As for sugar levels, it has a similar effect on cells, but the opposite of insulin. When sugar levels are low, glucogen instructs muscle and liver cells to activate glucose in the form of glucogen, through glycogenolysis. Stimulates the kidneys and liver to generate its own glucose through gluconeogenesis.
As a result, glucagon collects glucose from various sources within our body in order to maintain it at sufficient levels. If this does not happen, then the sugar level becomes very low.
How does the body understand when it is necessary to normalize sugar levels?
During the day, a normal balance between insulin and glucogen is maintained in the blood. Let's give an example of what processes occur in the body immediately after eating. After you eat, your body gets amino acids, fatty acids and glucose from food. The body analyzes them and triggers beta cells in your pancreas to produce insulin in the blood. This process tells the pancreas not to release glucogen in order to encourage the body to use glucose as a source of nutrition. Insulin rises along with sugar levels and sends it to muscle cells and the liver for use as an energy source. This keeps the levels of glucose, amino acids and fatty acids in the blood from going too high and helps keep sugar levels stable.
There may be times when you skipped your breakfast or during the night your body needs additional resources to maintain normal sugar levels until next appointment food. When you haven't eaten, your body's cells still need glucose to function properly. When blood sugar levels drop due to lack of food, alpha cells in the pancreas begin to produce glucogen to stop insulin production and instruct the liver and kidneys to produce glucose from glucogen stores through metabolic processes. This helps keep your sugar levels stable and avoid unpleasant consequences for good health.
Diabetes
Sometimes the body malfunctions, disrupting the metabolic process. As a result, enough insulin is no longer produced or our body cells begin to react incorrectly to it, as a result, blood sugar levels rise. This metabolic disorder is called diabetes mellitus.
What blood sugar level is considered normal?
Adults
The glucose concentration on an empty stomach in a healthy person should be between 3.6 and 5.8 mmol/L (65 and 105 mg/dL).
In the morning on an empty stomach, the normal blood sugar level for adult men and women should be between 3.8 and 6.0 mmol/l (68 and 108 mg/dl).
Two hours after eating or drinking foods containing large amounts of carbohydrates, values should be between 6.7 and 7.8 mmol/L (120 and 140 mg/dL).
Children
Normal blood sugar levels in children 6 years of age and younger before meals are considered to be between 5 mmol/L (100 mg/dL) and 10 mmol/L (180 mg/dL). At bedtime, these values should be 6.1 mmol/L (110 mg/dL) to 11.1 mmol/L (200 mg/dL).
In children from 6 to 12 years old, the sugar level should be between 5 mmol/l (90 mg/dl) and 10 mmol/l (180 mg/dl), before bedtime 5.5 mmol/l (100 mg/dl) and 10 mmol/ l (180 mg/dl). For children aged 13 to 19 years, the numbers should be the same as for adults.

Signs of sugar levels that are outside the normal range
When the blood sugar level goes beyond the acceptable limit, the following symptoms appear:
Feeling thirsty
If you're constantly thirsty, your blood sugar may be high, which could be a sign of diabetes. When your body can't maintain normal sugar levels, your kidneys work harder to filter out the excess. At this point, they consume additional moisture from the tissues, which leads to a frequent urge to urinate. The feeling of thirst is a signal to replenish missing fluid reserves. If there is not enough of it, dehydration will occur.
Fatigue
Overwork and feeling tired can also be a sign of diabetes. When sugar does not enter the cells, but simply remains in the blood, they do not receive enough energy. Therefore, you may feel slightly tired or overtired to the point that you want to take a nap.
Dizziness
Feeling confused or dizzy may be signs of high blood sugar. For normal operation your brain needs sugar, and its lack can be very dangerous, even leading to functional impairment, if you do not pay attention to this problem. Even a regular glass of fruit juice can bring your sugar levels back to normal. If dizziness frequently bothers you, consult your doctor to adjust your diet or treatment in general.
Legs and arms swell
Diabetes and high blood pressure are two factors that can lead to kidney problems and impair fluid filtration function. Because of this, excess fluid can accumulate in the body, leading to swelling of the arms and legs.
Numbness and tingling
Nerve damage may also be a symptom chronic problems sugar control. As a result, your arms and legs go numb, and you feel pain in your limbs when the ambient temperature changes.
You're losing your sight
What does visual impairment look like?
High sugar and blood pressure together can damage the sensitive organs of your eyes and lead to poor vision. Diabetic retinopathy occurs due to damage to the blood vessels inside the eye, which is a common problem with vision loss as people age. Fog before the eyes, dots, lines or flashes are a signal to consult a doctor.
As well as other signs, such as:
- Stomach problems (diarrhea, constipation, incontinence);
- Rapid weight loss;
- Skin infections;
- Non-healing wounds.
Important: Symptoms of level 1 diabetes appear abruptly, they are pronounced and last a long time. In type 2 diabetes, symptoms appear slowly, are difficult to recognize, and may not appear at all.
How to measure your sugar level
A device for measuring blood glucose.
It is very easy to measure blood sugar levels; for this, there are special, individual devices - glucometers. Each such device comes complete with special test strips.
In order to take measurements, a small amount of blood must be applied to the strip. Next, you need to place the strip in the device. Within 5-30 seconds, the device should generate and display the analysis result.
The best way to take a blood sample from a finger is to prick it with a special lancet that serves this purpose. When piercing a finger, it is necessary to pre-treat the puncture site with medical alcohol.
Advice on choosing a device:
Exists great amount all kinds of models different sizes and shapes. In order to choose the right one, it is best to consult with your doctor and clarify the advantages of this model over others.
How to reduce sugar levels
Sugar levels are measured on an empty stomach. In a healthy person, the normal blood sugar range is 3.6 - 5.8 mmol/l (65 - 105 mg/dl). By measuring its level, we can say that the result will be 3 values:
- Normal sugar level (blood glucose level on an empty stomach).
- Impaired glycemia - prediabetes (glucose value on an empty stomach is increased to a maximum value of 6.1 to 6.9 mmol/l (110 to 124 mg/dl).
- Diabetes (high sugar levels reaching 7.0 mmol/L (126 mg/dL) or higher).
If the level of sugar in your blood is at the highest level - in the prediabetes stage, this does not mean at all that you will definitely have diabetes in the future.
This is a reason to start leading an active lifestyle and get treatment before the disease begins to develop and take over, and probably prevent it altogether.Dr. Greg Geretiv, Chief of Endocrinology at St. Peter's Hospital, Albany, New York.
In order for your blood sugar to be normal, you need to:
- Maintain optimal body weight;
- It is necessary to eat properly, adhering to special diets (which include a lot of vegetables, fruits, fiber, few calories, fats, and exclude alcohol);
- Get a good night's sleep and devote enough time to rest:
- go to bed and get up at the same time, do not look at the TV, computer or your phone while falling asleep;
- do not drink coffee after dinner;
- Exercise for at least 30 minutes a day (including exercises, aerobics and other aerobic exercise).
Is it possible to completely recover from diabetes?
IN currently No known methods or medications to treat diabetes. In type 1 diabetes, the body cannot produce insulin because the cells responsible for its production are completely destroyed. Science does not yet know how to restore or replace them. You will constantly need insulin to maintain normal sugar levels.
With type 2 diabetes, the body simply does not know how to properly use the insulin produced (this failure of the body is called insulin resistance).
However, with exercise and proper diet, sugar levels can be controlled and you can live a normal life.

Cholesterol (CS) is a substance from which the human body forms atherosclerotic plaques. They are the cause of the manifestation, which is a very dangerous disease.
What cholesterol is can be judged by the meaning of this word, which is translated from Greek as “hard bile.”
Substance belonging to the class lipids , comes with food. However, in this way, only a small part of the cholesterol enters the body - approximately 20% of the cholesterol a person receives mainly from products of animal origin. The remaining, more significant part of this substance (approximately 80%) is produced in the human liver.
In the human body, pure Chl is present only in small quantities, being part of lipoproteins. These compounds may have low density (so-called bad LPN cholesterol ) and high density (the so-called good cholesterol LPV ).
What should be the normal cholesterol level, as well as good and bad cholesterol - what it is, you can find out from this article.
Cholesterol: good, bad, total
The fact that if cholesterol levels are higher than normal is harmful is said very often and actively. Therefore, many people are under the impression that the lower the cholesterol, the better. But in order for all systems in the body to function normally, this substance is very important. It is important that a person’s cholesterol remains normal throughout his life.
It is customary to distinguish between so-called bad and good cholesterol. Low cholesterol (bad) is the one that settles on the walls inside the blood vessels and forms plaques. It has low or very low density and binds to special types of protein - apoproteins . As a result, VLDL fat-protein complexes . Precisely in the event that LDL norm increases, a dangerous health condition is noted.
VLDL - what it is, the norm of this indicator - all this information can be obtained from a specialist.
Now the LDL norm in men and the LDL norm in women after 50 years of age and at a younger age are determined by conducting cholesterol tests and are expressed by different laboratory methods, the units of determination are mg/dL or mmol/L. You need to understand when determining LDL that this is a value that should be analyzed by a specialist and prescribed appropriate treatment if LDL cholesterol increased. What this means depends on the metrics. So, in healthy people it is normal this indicator considered to be below 4 mmol/L (160 mg/dL).
If a blood test shows that cholesterol is high, you should ask your doctor what to do. As a rule, if the value of such cholesterol is elevated, this means that the patient will be prescribed, or this condition should be treated with medications.
The question of whether you should take cholesterol pills is controversial. It is important to note that statins do not eliminate the causes of high cholesterol. It's about o , low mobility, . only suppress the production of this substance in the body, but at the same time they provoke numerous side effects. Sometimes cardiologists say that the use of statins is more dangerous for the body than elevated levels.
- In people suffering from ischemic heart disease, who have had or, cholesterol levels must be below 2.5 mmol/l or 100 mg/dl.
- Those who do not suffer from heart disease, but have more than two risk factors, need to maintain cholesterol level at 3.3 mmol/l or below 130 mg/dl.
Bad cholesterol is counteracted by so-called good cholesterol, HDL cholesterol. What is high-density lipoprotein cholesterol? It is an essential substance for the body, as it collects bad cholesterol from the walls of blood vessels, after which it promotes its removal to the liver, where it is destroyed. Many people are interested: if HDL is lowered, what does this mean? It should be borne in mind that this condition is dangerous, since atherosclerosis develops not only against the background of increased low-density cholesterol, but also if LDL cholesterol is reduced. If HDL cholesterol is elevated, what does this mean, you need to ask a specialist.
That is why the most undesirable option in adults is when the level of bad cholesterol is increased and the level of useful cholesterol is decreased. According to statistics, approximately 60% of people mature age This combination of indicators is noted. And the earlier such indicators can be determined and treatment carried out correctly, the lower the risk of developing dangerous diseases.
Good cholesterol, unlike bad cholesterol, is produced only by the body, so increase its level by consuming certain products, will not work.
The norm of good cholesterol in women is slightly higher than normal cholesterol HDL in men. Most important recommendation Regarding how to increase its level in the blood, the following: it is necessary to practice physical activity, during which its production increases. Even if you do ordinary exercises at home every day, this will help not only increase HDL, but also reduce levels of bad cholesterol, which comes into the body from food.
If a person has eaten food that contains very high cholesterol, to activate its removal it is necessary to provide active work muscles of all groups.
Thus, those who want the LDL and HDL levels to be restored need to:
- move more (especially for those who have suffered a heart attack or stroke);
- exercise moderately;
- practice intense physical activity (in the absence of contraindications).
You can also increase the level of good cholesterol by taking a small dose of alcohol. However, in no case should it be more than one glass of dry wine per day.
It is important to consider that excessive load threatens to suppress the synthesis of cholesterol.
To correctly decipher a blood test, you should take into account the level of cholesterol in a person’s blood.
There is a table of cholesterol norms for women by age, from which, if necessary, you can find out what the cholesterol norm is for women after 50 years of age, and what the norm is considered to be for women at a young age. Accordingly, the patient can independently determine whether she has an increased or low cholesterol and consult a doctor who can help you find out the reasons for low or high levels. It is the doctor who determines what treatment and diet should be.
- The normal level of cholesterol in the blood for women and men based on HDL, if the condition of the heart and blood vessels is normal, is above 1 mmol/l or 39 mg/dl.
- In people with coronary artery disease who have had a stroke or heart attack, the indicator should be 1-1.5 mmol/l or 40-60 mg/dl.
The analysis process also determines the norm of total cholesterol in women and men, that is, how good and bad cholesterol correlate.
Total cholesterol in the blood should be no more than 5.2 mmol/l or 200 mg/dl.
If the norm is for men young even slightly exceeded, then this must be considered a pathology.
There is also a table of cholesterol norms in men by age, which can easily be used to determine the cholesterol norm in men and its indicators at different ages. From the corresponding table you can find out what norm of hdl-cholesterol is considered optimal
However, in order to determine whether the level in men and women is actually normal for this indicator, first of all, you need to do a blood test, which makes it possible to find out the content of total cholesterol, as well as the content of other indicators - low or high sugar and etc.
After all, even if the norm of total cholesterol is noticeably exceeded, it is impossible to determine the symptoms or special signs of such a condition. That is, a person does not even realize that the norm has been exceeded, and his blood vessels are clogged or narrowed, until he begins to notice that he has pain in the heart, or until a stroke or heart attack occurs.
Therefore, it is important even for a healthy person of any age to get tested and monitor whether the permissible norm cholesterol. Also, each person should prevent an increase in these indicators in order to avoid the development of atherosclerosis and other serious ailments in the future.
Who needs to control cholesterol levels?
If a person is healthy, he does not show negative symptoms, he does not need to think about the state of blood vessels or check whether the level is normal Cholesterol takes place in the body. That is why it is often elevated level Patients are not even aware of this substance at first.
This indicator should be measured especially carefully and regularly for those who suffer from hypertension or have problems with the heart and blood vessels. In addition, indications for regular tests have the following categories:
- people who smoke;
- those who are sick hypertension ;
- overweight people;
- patients suffering from diseases of the cardiovascular system;
- those who prefer a sedentary life;
- women after ;
- men after reaching 40 years of age;
- aged people.
Those who need a blood test for cholesterol should ask appropriate professionals about how to take a cholesterol test. The blood formula, including cholesterol content, is determined. How to donate blood for cholesterol? Such an analysis is carried out in any clinic, for this purpose from ulnar vein Approximately 5 ml of blood is taken. Those who are interested in how to donate blood correctly should note that before these indicators are determined, the patient should not eat for half a day. Also, in the period before blood donation, you should not engage in intense physical activity.
There is also a special test for use at home. These are disposable test strips that are easy to use. The portable analyzer is used by people with lipid metabolism disorders.
How to decipher a blood test
You can find out whether total cholesterol is elevated by conducting a blood test in the laboratory. If total cholesterol is elevated, what does this mean, how to act, and everything about treatment will be explained by your doctor. But you can try to decipher the test results yourself. To do this, you need to know that the biochemical analysis contains three indicators: LDL cholesterol, HDL cholesterol and total cholesterol.
Lipidogram - This comprehensive study, allowing you to evaluate lipid metabolism in the body, which allows you to determine how lipid metabolism occurs and calculate the risk of atherosclerosis and coronary artery disease.
Correct interpretation of the blood lipid profile is also important from the point of view of assessing the need to take statins, daily dose such drugs. Statins are drugs that have many side effects, and their price is quite high. Therefore, based on what it is - a lipid profile, this analysis allows you to find out what a person’s blood consists of and prescribe the most effective therapy to the patient.
After all, total cholesterol is an indicator that in itself does not make it possible to clearly assess the likelihood of a patient developing atherosclerosis. If your total cholesterol is elevated, what should you do? You can evaluate it on the full spectrum. diagnostic indicators. Therefore, the following indicators are determined:
- HDL (alpha cholesterol) – it is determined whether high-density lipoproteins are increased or decreased. It is taken into account when determining the parameters of β-lipoproteins that this substance performs a protective function, preventing the development of atherosclerosis.
- LDL – low-density lipoproteins are increased or decreased. The higher the beta cholesterol level, the more activated the atherosclerotic process.
- VLDL – very low density lipoproteins, thanks to which exogenous lipids are transported in plasma. Synthesized by the liver, they are the main precursor of LDL. VLDL is taken Active participation in the production of atherosclerotic plaques.
- Triglycerides – these are esters of higher fatty acids and glycerol. This is a transport form of fats, therefore they are increased content also increases the risk of atherosclerosis.
What normal cholesterol should be is determined depending on age; it can be different for women and men. Moreover, it is important to understand that exact number, which indicates the norm of cholesterol, no. There are only recommendations on what the index should be. Therefore, if the indicator is different and deviates from the range, then this is evidence of some kind of disease.
However, those who are planning to take the test should take into account that certain errors may occur during the analysis. The data from the study showed that in 75% of laboratories in the country such errors are allowed. What to do if you are trying to get exact result? It is best to do such analyzes in those laboratories that are certified by the VCS (Invitro, etc.)
Normal cholesterol levels in women
- Normally, in women, the total chol level is 3.6-5.2 mmol/l;
- Cholesterol, moderately elevated – 5.2 – 6.19 mmol/l;
- Hc, significantly increased - from more than 6.19 mmol/l.
- LDL cholesterol: normal indicator– 3.5 mmol/l, elevated – from 4.0 mmol/l.
- HDL cholesterol: normal level is 0.9-1.9 mmol/l, a level below 0.78 mmol/l is considered dangerous to health.

Triglycerides
Triglycerides are a specific type of fat found in human blood. They are the main source of energy and the most abundant type of fat in the body. A complete blood test determines the amount of triglycerides. If it is normal, then these fats are beneficial for the body.
As a rule, triglycerides in the blood are elevated in those who consume more calories than they burn. When their levels are elevated, the so-called metabolic syndrome , at which it is noted high blood pressure, increased blood sugar is noted low content good cholesterin, and also have a large amount of fat around the waist. This condition increases the likelihood of developing diabetes, stroke, and heart disease.
The normal triglyceride level is 150 mg/dl. The normal level of triglycerides in the blood of women, as well as men, is exceeded if the level is more than 200 mg/dl. However, the rate is up to 400 mg/dl. is designated as acceptable. A high level is considered to be 400-1000 mg/dl. very high – from 1000 mg/dl.
If triglycerides are low, what does this mean, you need to ask your doctor. This condition is observed in lung diseases, cerebral infarction, parenchymal damage, myasthenia gravis, when taken, etc.
What is the atherogenic coefficient
Many people are interested in what is the atherogenic coefficient in a biochemical blood test? Atherogenic coefficient It is customary to call the proportional ratio of good and total cholesterin. This indicator is the most accurate reflection of the state of lipid metabolism in the body, as well as an assessment of the likelihood of atherosclerosis and other ailments. To calculate the atherogenic index, you need to subtract the HDL cholesterol value from the total cholesterol value, and then divide this difference by the HDL cholesterol level.
The norm for women and the norm for men of this indicator is as follows:
- 2-2.8 – young people under 30 years old;
- 3-3.5 is the norm for people over 30 years old who do not have signs of atherosclerosis;
- from 4 – an indicator typical for people suffering from coronary artery disease.
If the atherogenic coefficient is below normal, then this is not a cause for concern. On the contrary, if the coefficient is reduced, then the person’s risk of atherosclerosis is low.
It is important to pay attention to the patient's condition if the atherogenicity coefficient is increased. A specialist will tell you what it is and how to act in this case. If a patient’s atherogenic coefficient is increased, the reasons for this are due to the fact that bad cholesterol is increased in the body. What to do in such a situation? First of all, you need to contact a qualified doctor who will adequately assess the atherogenic index. What this means can only be clearly assessed and explained by a specialist.
Atherogenicity – this is the main criterion for monitoring how effective hypercholesterolemia therapy is. One should strive to ensure that lipoprotein levels are restored. It is important to ensure not only a decrease in total cholesterol, but also an increase in high-density lipoproteins. Therefore, decoding the lipid spectrum of the blood provides that β-lipoproteins, the norm for which is different in women and men, as already noted, are necessarily taken into account when assessing the patient’s condition.
Other studies for high cholesterol
If there is a risk of atherosclerosis, they are determined not only by lipoproteins (normal in the blood), but also by others important indicators, in particular, also the norm of PTI in the blood of women and men. PTI is the prothrombin index, one of the most important factors coagulograms, studies of the state of the blood coagulation system.
However, currently in medicine there is a more stable indicator - INR , which stands for international normalization ratio. If the level is elevated, there is a risk of bleeding. If the INR is elevated, a specialist will explain in detail what this means.
The definition of hgb() is also important because when high level cholesterol, hemoglobin levels can be very high, and this increases the risk of heart attack, stroke, thrombosis, etc. How much hemoglobin should be normal can be found out from a specialist.
Other indicators and markers (he4), etc. are determined in people with high cholesterol if necessary.
What to do to normalize cholesterol?
Many people, having received test results and learned that they have cholesterol 7 or cholesterol 8, simply have no idea what to do. The basic rule in this case is the following: clinical analysis blood must be deciphered by a specialist, whose recommendations should be followed. That is, if low-density lipoproteins are elevated, the doctor should explain what it is. In the same way, if there is low cholesterol in the blood, what does this mean, you should ask a specialist.
As a general rule, it is important to be strictly followed in men as well as in women. Its conditions are not difficult to understand. It is enough just not to consume products with saturated fat, and dangerous dietary cholesterol. There are some important tips to keep in mind:
- significantly reduce the amount of animal fats in the diet;
- reduce portions fatty meat, remove skin from poultry before consumption;
- reduce portions butter, mayonnaise, sour cream with high fat content;
- prefer boiled rather than fried foods;
- You can eat eggs without overdoing them;
- the diet should contain a maximum of healthy fiber (apples, beets, legumes, carrots, cabbage, kiwi, etc.);
- useful to consume vegetable oils, fish.
If cholesterol is elevated with, it is important to strictly adhere to the doctor’s recommendations - it is he who will tell you which diet plan is most relevant in this case.
Seeing cholesterol 6.6 or cholesterol 9 in test results, what to do, the patient should ask a specialist. It is likely that the doctor will prescribe treatment based on the patient’s individual characteristics.
You should clearly remember that normal Chl levels are the key to the health of your blood vessels and heart, and do everything to improve these indicators
Normal fat metabolism occurs if the indicators are close to the following values.
Cholesterol in the blood: meaning, analysis and deviations from the norm, what to do if it’s elevated
Cholesterol modern man is considered the main enemy, although several decades ago it was not given such great importance. Being carried away by new, recently invented products, often in their composition very far from those consumed by our ancestors, ignoring the diet, a person often does not understand that the main share of the blame for the excessive accumulation of cholesterol and its harmful fractions lies with himself. The “crazy” rhythm of life, which predisposes to the disorder, does not help fight cholesterol. metabolic processes and the deposition of excess fat-like substances on the walls of arterial vessels.
What's good and bad about it?
Constantly “scolding” this substance, people forget that people need it, since it brings many benefits. What's good about cholesterol and why shouldn't it be eliminated from our lives? So, its best aspects:
- Secondary monohydric alcohol, a fat-like substance called cholesterol, in a free state, together with phospholipids, is part of the lipid structure of cell membranes and ensures their stability.
- Cholesterol in human body, breaking down, serves as a source of formation of adrenal hormones (corticosteroids), vitamin D 3 and bile acids, which play the role of fat emulsifiers, that is, it is a precursor of highly active biological substances.
But in other way Cholesterol can cause various problems:
Patients often discuss the bad properties of cholesterol among themselves, share experiences and recipes on how to lower it, but this can be useless if everything is done at random. A diet will help to slightly reduce the level of cholesterol in the blood (again, what?) folk remedies and a new lifestyle aimed at improving health. For successful solution question, you need to not just take total cholesterol as a basis in order to change its values, you need to figure out which fraction should be lowered so that the others return to normal.
How to decipher the analysis?
The level of cholesterol in the blood should not exceed 5.2 mmol/l, however, even a concentration value approaching 5.0 cannot give full confidence is that everything is fine in a person, since the total cholesterol content is not absolutely reliable sign well-being. Normal cholesterol levels in a certain proportion are different indicators, which are impossible to determine without a special analysis called a lipid spectrum.
The composition of LDL cholesterol (atherogenic lipoprotein), in addition to LDL, includes very low-density lipoproteins (VLDL) and “remnants” (the so-called remnants from the reaction of transition of VLDL to LDL). All this may seem very complicated, however, if you figure it out, decoding the lipid spectrum can be mastered by anyone interested.
Usually when carrying out biochemical tests Cholesterol and its fractions are divided into:
- Total cholesterol (normal up to 5.2 mmol/l or less than 200 mg/dl).
- The main “vehicle” of cholesterol esters is low-density lipoproteins (LDL). In a healthy person, they have their 60-65% of the total amount (or cholesterol level LDL (LDL + VLDL) does not exceed 3.37 mmol/l). In those patients who have already been affected by atherosclerosis, LDL-C values may increase markedly, which occurs due to a decrease in the content of antiatherogenic lipoproteins, that is, this indicator is more informative regarding atherosclerosis than the level of total cholesterol in the blood.
- High density lipoproteins(HDL cholesterol or HDL cholesterol), which women should normally have more than 1.68 mmol/l(for men the lower limit is different - higher 1.3 mmol/l). In other sources you can find slightly different figures (in women - above 1.9 mmol/l or 500-600 mg/l, in men - above 1.6 or 400-500 mg/l), this depends on the characteristics of the reagents and the methodology carrying out the reaction. If the level of HDL cholesterol becomes less than acceptable values, they cannot fully protect the blood vessels.
- Such an indicator as atherogenic coefficient, which indicates the degree of development of the atherosclerotic process, but is not the main diagnostic criterion, is calculated using the formula: CA = (TC - HDL-C): HDL-C, its normal values range from 2-3.
Cholesterol tests do not necessarily require the isolation of all fractions separately. For example, VLDL can be easily calculated from the concentration using the formula (VLDL-C = TG: 2.2) or the sum of high-density and very low-density lipoproteins can be subtracted from total cholesterol to obtain LDL-C. Perhaps these calculations will not seem interesting to the reader, because they are presented only for informational purposes (to have an idea of the components of the lipid spectrum). In any case, the doctor is responsible for decoding, and he also performs necessary calculations on positions of interest to him.
And more about the normal level of cholesterol in the blood
Readers may have come across information that the normal level of cholesterol in the blood is up to 7.8 mmol/l. Then they can imagine what the cardiologist will say when they see such an analysis. Definitely - he will appoint all lipid spectrum. Therefore once again: normal level cholesterol is considered an indicator up to 5.2 mmol/l(recommended values), borderline up to 6.5 mmol/l (risk of development!), and everything higher is correspondingly elevated (cholesterol is dangerous in high numbers and, probably, the atherosclerotic process is in full swing).
Thus, the concentration of total cholesterol in the range of 5.2 – 6.5 mmol/l is the basis for conducting a test that determines the level of antiatherogenic lipoprotein cholesterol (HDL-C). Cholesterol analysis should be carried out after 2 - 4 weeks without abandoning the diet or taking medications, testing is repeated every 3 months.
About the lower bound
Everyone knows and talks about high cholesterol, everyone is trying to reduce it available means, but almost never take into account the lower limit of the norm. It's as if she doesn't exist. Meanwhile, low cholesterol may be present in the blood and accompany quite serious conditions:
- Prolonged fasting to the point of exhaustion.
- Neoplastic processes (depletion of a person and absorption of cholesterol from his blood by a malignant neoplasm).
- Severe liver damage (last stage of cirrhosis, dystrophic changes and infectious lesions of the parenchyma).
- Lung diseases (tuberculosis, sarcoidosis).
- Hyperfunction of the thyroid gland.
- (megaloblastic, thalassemia).
- Lesions of the central nervous system (CNS).
- Prolonged fever.
- Typhus.
- Burns with significant damage to the skin.
- Inflammatory processes in soft tissues with suppuration.
- Sepsis.
As for cholesterol fractions, they also have lower limits. For example, lowering high-density lipoprotein cholesterol levels beyond 0.9 mmol/l (antiatherogenic) associated with risk factors for coronary artery disease(physical inactivity, bad habits, overweight, ), that is, it is clear that people develop a tendency because their blood vessels are not protected, because HDL becomes unacceptably low.
Low cholesterol in the blood, representing low-density lipoproteins (LDL), is observed in the same pathological conditions as total cholesterol (depletion, tumors, serious illnesses liver, lungs, anemia, etc.).
Cholesterol in the blood is increased
First, about the causes of high cholesterol, although, probably, they have long been known to everyone:
- Our food and above all - products of animal origin (meat, whole full fat milk, eggs, cheeses of all kinds) containing saturated fatty acids and cholesterol. The craze for chips and all sorts of quick, tasty, filling fast foods saturated with various trans fats also does not bode well. Conclusion: such cholesterol is dangerous and its consumption should be avoided.
- Body mass– excess increases the level of triglycerides and reduces the concentration of high-density lipoproteins (anti-atherogenic).
- Physical activity. Physical inactivity is a risk factor.
- Age after 50 years and male gender.
- Heredity. Sometimes high cholesterol runs in families.
- Smoking Not that it greatly increases total cholesterol, but it does a good job of reducing the level of the protective fraction (CH - HDL).
- Taking certain medications(hormones, diuretics, beta blockers).
Thus, it is not difficult to guess who is primarily prescribed a cholesterol test.
Diseases with high cholesterol
Since so much has been said about harm high cholesterol and about the origin of such a phenomenon, then it would probably be useful to note under what circumstances this indicator will increase, since they, too, to some extent may cause high blood cholesterol:
- Hereditary metabolic disorders (familial variants caused by metabolic disorders). As a rule, these are severe forms, characterized by early manifestation and particular resistance to therapeutic measures;
- Cardiac ischemia;
- Various liver pathologies (hepatitis, jaundice of non-liver origin, obstructive jaundice, primary biliary cirrhosis);
- Severe kidney disease with renal failure and swelling:
- Hypofunction of the thyroid gland (hypothyroidism);
- Inflammatory and tumor diseases of the pancreas (pancreatitis, cancer);
- (it’s hard to imagine a diabetic without high cholesterol - this is, in general, rare);
- Pathological conditions of the pituitary gland with decreased production of somatotropin;
- Obesity;
- Alcoholism (alcoholics who drink but do not eat have high cholesterol, but atherosclerosis does not develop often);
- Pregnancy (the condition is temporary, the body will adjust everything after the end of the period, but diet and other prescriptions will not interfere with a pregnant woman).
Of course, in such situations, patients no longer think about how to lower cholesterol; all efforts are aimed at combating the underlying disease. Well, those for whom everything is not so bad still have a chance to preserve their blood vessels, but it will no longer be possible to return them to their original state.
Fight cholesterol
As soon as a person learned about his problems in the lipid spectrum, studied the literature on the topic, listened to the recommendations of doctors and simply knowledgeable people, his first desire is to lower the level of this harmful substance, that is, to begin treating high cholesterol.
The most impatient people ask to immediately assign them medicines, others prefer to do without “chemistry”. It should be noted that opponents of drugs are right in many respects - you need to change yourself. To do this, patients switch to and become a little vegetarian in order to free their blood from “bad” components and prevent new ones from entering with fatty foods.
Food and cholesterol:
A person changes his way of thinking, he tries to move more, goes to the pool, prefers leisure on fresh air, removes bad habits. For some people, the desire to reduce cholesterol becomes the meaning of life, and they begin to actively take care of their health. And it is right!
What does it take to be successful?
Among other things, in search of the most effective remedy against cholesterol problems, many people are carried away by those formations that have already settled on the walls of the arteries and damage them in some places. Cholesterol is dangerous in a certain form (cholesterol - LDL, cholesterol - VLDL) and its harmfulness lies in the fact that it contributes to the formation of atherosclerotic plaques on the walls of arterial vessels. Such measures (fighting plaques) undoubtedly have a positive effect in terms of general cleansing, preventing excessive accumulation of harmful substances, and stopping the development of the atherosclerotic process. However, regarding removal cholesterol plaques, then the reader will have to be somewhat disappointed here. Once formed, they never go away. The main thing is to prevent the formation of new ones, and this will already be a success.
When things go too far, folk remedies stop working, and the diet no longer helps, the doctor prescribes cholesterol-lowering drugs (most likely, these will be statins).
Difficult treatment
(lovastatin, fluvastatin, pravastatin, etc.), reducing the level of cholesterol produced by the patient’s liver, reduce the risk of developing (ischemic stroke) and, and thereby help the patient avoid fatal outcome from this pathology. In addition, there are combined statins (Vytorin, Advicor, Kaduet), which not only reduce the amount of cholesterol produced in the body, but also perform other functions, for example, lower blood pressure, affect the ratio of “bad” and “good” cholesterol.
Probability of getting drug therapy immediately after determining the lipid spectrum increases at patients with diabetes mellitus, arterial hypertension, problems with coronary vessels, since their risk of myocardial infarction is much higher.
Under no circumstances should you follow the advice of friends, the World Wide Web, or other dubious sources. Medicines in this group can only be prescribed by a doctor! Statins are not always combined with others medicines, which the patient is forced to constantly take if there is chronic diseases, so his independence will be absolutely inappropriate. In addition, during the treatment of high cholesterol, the doctor continues to monitor the patient’s condition, monitors lipid levels, and supplements or discontinues therapy.
Who's first in line for analysis?
One can hardly expect the lipid spectrum to be on the list of priority biochemical research used in pediatrics. Cholesterol tests are usually taken by people with some life experience, more often male and well-fed, burdened with the presence of risk factors and early manifestations atherosclerotic process. Reasons for conducting appropriate tests include:
- Cardiovascular diseases, and primarily coronary heart disease (patients with coronary artery disease are more aware of their lipid profile than others);
- Arterial hypertension;
- Increased content; (hyperuricemia);
- Having bad habits such as smoking;
- Obesity;
- The use of corticosteroid hormones, diuretics, beta blockers.
- Treatment with cholesterol-lowering drugs (statins).
A cholesterol test is taken from a vein on an empty stomach. On the eve of the study, the patient must adhere to a low-cholesterol diet and extend the overnight fast to 14 - 16 hours, however, the doctor will definitely inform him about this.
Total cholesterol is determined in the blood serum after centrifugation, triglycerides too, but you will have to work on the sedimentation of fractions; this is a more labor-intensive study, but in any case the patient will learn about its results by the end of the day. The numbers and the doctor will tell you what to do next.
