Low blood pressure. Danger of low blood pressure

Arterial hypotension is characterized by a decrease in central blood pressure. At the same time, the decrease can be called critical, since it is approximately 20% or more of the norm. Hypotension is said to be when the pressure reaches 90/60.

When the pressure drops, the brain begins to suffer from a lack of nutrients, oxygen, since all this is supplied through the bloodstream. It must be stable. As a result, the patient suffers from drowsiness, weakness and dizziness, fainting, severe fatigue.

Quite often, women aged about 30 to 40 who are actively involved in intellectual activities suffer from low blood pressure. Older people are already developing hypotension of the atherosclerotic type, associated with a sharp deterioration in the condition of the vessels that are already affected by atherosclerosis. The heart muscle also becomes flabby. Blood circulation slows down and blood pressure drops.

Occupational hypotension also often develops. It is a kind of protective reaction of the body. This is traditional for professional ballerinas, athletes who experience excessive physical exertion. The decrease in pressure makes them relax, relax.

Chronic and temporary hypotension associated with weather and climatic conditions is likely. A temporary decrease in pressure occurs during acclimatization, when a person enters a different climatic zone. Regular drops in pressure are typical for patients with meteorological dependence. They respond to air temperature, humidity and precipitation, as well as to electromagnetic radiation.

Diagnostics

The easiest way to determine low blood pressure is with a tonometer. In this case, a whole range of additional diagnostic methods is used. The level of cortisol is determined, they are also usually done as part of the ECHO-KG, ECG examination, they must pass general blood and urine tests, and separately examine the blood for the presence of electrolytes.

The examination may also include brain tomography, MRI, to determine the state of the brain vessels, to identify defects, such as constrictions, due to which the general blood flow becomes difficult and pressure drops. This also includes ultrasound of the vessels in the lower extremities, the abdominal cavity.

The main causes of hypotension

Let's highlight the key risk factors, the characteristic causes of low pressure. Unfortunately, the pressure drops most often unexpectedly, for no apparent reason.

Important! If this begins to happen regularly, it is important to undergo an appropriate examination: identify the causes, determine the main risk factors, and start drug therapy. It is very important to eliminate the causes of pressure drop.

Here are the most common causes of low blood pressure.

Physical inactivity. A person suffers from insufficient motor activity, which weakens the function of the heart, and the overall volume of muscle activity decreases.
Excessive physical activity. The body itself lowers the pressure, provoking a forced rest.
Acclimatization. Characteristic for moving to the Arctic, the tropics, highlands.
Disruptions in the endocrine system. Most often, the pressure drops with hypoglycemia, renal failure.
General decrease in the tone of blood vessels. This happens with anaphylactic, as well as with septic shock.
Heart disease also provokes a drop in blood pressure. These can be malfunctions in the functioning of the heart valves, heart attack, bradycardia.
Blood flow is hampered by injuries of the spinal cord, brain, and also by mixing the cervical vertebrae.
Sometimes the pressure can drop sharply due to a decrease in the total volume of circulating blood. This is the so-called hypovolemic shock. It happens with burns, blood loss.
Vegetative disruption of the heart (everyone knows vegetative-vascular dystonia).
Orthostatic type of hypotension. It occurs with a sharp change in body position, most often when moving from a lying to a vertical position.
Failures in the psychological state. Chronic fatigue and sleep disturbances, permanent stress and depressive states, panic disorders and psychological trauma cause a decrease in pressure, a general drop in body tone.
Imbalance in the ratio of work and rest, physical overwork also provokes hypotension.
Pregnancy. In the process of carrying a baby, a woman significantly increases the total volume of the circulatory system. As a result, the tone of the arteries may weaken.
In critical conditions, a pressure drop is also observed. In particular, this is typical for renal and pulmonary insufficiency, cardiac disorders.
Nutrient deficiencies in good nutrition are also hazardous to health.

These are the main reasons that are the most widespread.

Clinical picture

In order to immediately identify signs of low blood pressure, it is necessary to immediately begin drug therapy and eliminate risk factors, it is necessary to know the general clinical picture of hypotension. If you immediately identify the cause of the ailment, you can quickly deal with the problem.

Here are the main symptoms:

apathy, drowsiness and lethargy;
memory impairment;
general weakness, overwork;
interruptions in breathing;
dizziness;
irritability, unstable emotional background;
pallor of the skin;
distraction;
fainting;
headache;
pain in the muscles, joints due to poor circulation;
dependence on weather conditions;
nausea, vomiting, lack of appetite;
violations in the digestive tract;
disruptions in the menstrual cycle, problems with potency.

It is important to note that in the aggregate, all these symptoms have an extremely negative impact on the general condition of a person, significantly worsen his quality of life. Therefore, treatment is necessary.

Types of hypotension

Consider the main types of hypotension and the corresponding causes of low blood pressure in each case. You can conditionally divide hypotension into several types. It is caused by various risk factors, on which, in turn, the course of the disease depends.

Type of hypotension	Characteristics, features
Chronic hypotension	Low blood pressure, which is most often about 90/60 mm Hg. Art. In most cases, young people are at risk. At the same time, in elderly patients, low blood pressure often causes a stroke. With such a low pressure, a person constantly feels weak, suffers from chronic overwork, sleep disturbances.
Acute symptomatic hypotension	The pressure may drop sharply. This accompanies acute allergic reactions, blood loss, as well as severe forms of arrhythmia, myocardial infarction. Also, the pressure drops sharply to critical levels when pulmonary embolism develops.
Primary hypotension	This disease is independent. Appears as a result of permanent stress, severe psychological, emotional overload. It is a disease of the vasomotor centers of the brain, which has a neurosis-like type
Secondary hypotension	Quite often, the pressure begins to drop due to other diseases that weaken the body and provoke a general breakdown, malfunctions of the heart vascular system. Also, the pressure may decrease due to drug therapy. This is typical for oncological ailments, arrhythmias and tuberculosis, stomach ulcers and anemia, brain injuries and any disturbances in the functioning of the circulatory system. The pressure also decreases due to improper diets, various intoxications, alcoholism.
Adaptation	This type of hypotension is associated with the process of adaptation of the body to unusual climatic conditions. Occurs due to a sharp change in weather, climatic conditions. Radiation background, electromagnetic radiation, humidity level also directly affect the pressure. Here we can talk about the meteorological dependence of patients who suffer from a sharp drop in pressure, weakness when the weather changes.
Occupational hypotension	Also, pressure can decrease due to various factors related to the professional activity of a person. Provoke hypotension substances-allergens, work at height, as well as underground, any work associated with great physical and psychological overload. Let's say a pressure drop is possible for professional athletes. Thus, the body itself puts up protection, causing a forced decrease in stress.

Pregnancy and low blood pressure

Special consideration deserves a decrease in blood pressure during pregnancy. In most cases, it is customary to talk about a predictable decrease in pressure due to the appearance of an additional blood supply system - that is, the uteroplacental system, which is formed for the baby. At the same time, there is an additional risk factor: the placenta produces special hormones that inhibit the activity of the pituitary gland, which also provokes a drop in pressure.

Important! The pressure should be stabilized, since its level significantly affects the mother's condition. In addition, the health of the baby and its development depend on the general blood circulation.

There are a number of factors that negatively affect blood pressure during pregnancy.

Pregnancy of twins, polyhydramnios.
Provokes a drop in pressure hormonal surge. This is especially true for the first trimester, when the progesterone content rises sharply.
There is iron deficiency anemia.
Sometimes you can identify the syndrome of the inferior vena cava.
In the last stages of pregnancy, venous blood flow may be disturbed due to a strong increase in body volume.
Pregnant women are characterized by a sedentary lifestyle, as well as an unhealthy diet. All this provokes hypotension. It is important to eliminate such risk factors.
An unstable emotional state, stress also cause a drop in pressure. It is imperative for a pregnant woman to monitor her psychological state.
Increased sensitivity to weather conditions.
Sometimes pregnancy causes exacerbations of various chronic diseases, as well as malfunctions of the endocrine and cardiovascular systems. This also has a negative effect on pressure.

It is necessary to take measures to stabilize the level of blood pressure. The necessary recommendations will be given by a specialist after the examination.

Dizziness, weakness, darkening of the eyes, nausea - all this may indicate a decrease in blood pressure (BP), while the tonometer usually shows from 105/70 mm r. Art. and below. There are many reasons for this state of affairs. Let's take a closer look at why pressure drops and what to do in such cases.

Low blood pressure causes headache and dizziness

Why does a person's blood pressure drop?

Low blood pressure - hypotension - can be inherited or acquired during life due to certain situations.

Impact of external factors

The following external factors can lead to slow blood movement:

prolonged stay in a state of severe nervous strain;
sedentary lifestyle;
constant lack of sleep;
harmful working conditions (hot shops, foundries);
the influence of drugs that can be prescribed after surgery on internal organs or during the treatment of cardiac pathologies: diuretics, muscle relaxants, antibiotics, antispasmodics, large doses of sedatives.

Sleep deprivation can cause high blood pressure

A significant expansion of blood vessels, from which blood pressure decreases in healthy people, occurs after visiting a bath, sauna, cosmetic procedures (wrap), thermal baths. The provoking factors of low pressure include head injuries, oncological pathologies, anemia of various origins.

Internal factors

In addition to external sources, due to which blood pressure may fall, there are also internal causes - pathological changes in the body. These are diseases that disrupt the speed of blood flow through the vessels: vegetovascular dystonia, cardiac pathologies (myocarditis, arrhythmia, various blockades). They slow down the work of the heart, the blood pumps through the veins more slowly, which leads to a loss of vascular tone and a decrease in peripheral pressure.

Aggravation of ulcerative processes in the stomach, inflammation of the pancreas, malfunction of the adrenal glands, as well as heavy bleeding can provoke a sharp decrease. In addition to pain in the places of localization of pathologies, weakness and dizziness can be observed. In such cases, blood pressure is restored when the underlying disease is eliminated.

Depressions of various kinds (asthenic, anhedonic and apathetic) are another factor that adversely affects peripheral pressure.

Frequent depression negatively affects human health

Hypotension is often a congenital pathology. People with this disease constantly have low blood pressure and feel good. But its upward jumps can significantly worsen the quality of life of such patients and require medical intervention.

If the pressure dropped during pregnancy, the cause of slow blood flow is toxicosis in the early stages, which is quite normal. In the second and third trimester, blood pressure does not fall (with the exception of congenital hypotension), but rises slightly. Therefore, a decrease in the indicators of the tonometer in the later stages of gestation should alert, especially when accompanied by discomfort in the abdomen and blood discharge (threat of miscarriage).

Low blood pressure symptoms

Low blood pressure means that the upper pressure is not less than 100-105 mm R. Art., and the lower - 60-70 mm p. Art. Hypotensive patients with such indicators feel good, but lowering the values \u200b\u200bmay cause them the following symptoms:

a significant decrease in efficiency (absent-mindedness, loss of strength, fatigue, excessive lethargy);
headaches in the back of the head;
shortness of breath, asthma attacks;
increased sweating (sharp cold sweat), the appearance of shortness of breath;
darkening in the eyes with a sharp rise from a position, sitting or lying down, dizziness and short-term disorientation;
low body temperature, slow pulse, nausea, vomiting, up to loss of consciousness.

Decreased blood pressure causes nausea and vomiting

In hypertensive patients (people with constantly high blood pressure), with a decrease in blood pressure, the listed signs appear very sharply, since the loss of the usual vascular tone and slow blood circulation puts an increased burden on the cardiovascular system and brain function.

Low pressure may be accompanied by a person's increased sensitivity to sudden changes in weather conditions (especially often observed in an elderly person). In addition, women are more likely to develop hypotension than men.

The pressure has dropped - what to do?

A sudden drop in pressure may indicate the development of a serious illness or be a negative reaction to a change in the environment. In any case, before the arrival of the doctor, it is necessary to provide first aid to the patient.

Lay the person on the bed, provide him with a state of rest so that he does not lose consciousness.
Raise the patient's legs up (put a pillow, a roller under the lower limbs). This will allow blood to arrive faster to the head and oxygenate the brain. Do a bladder massage.
Make sure that the clothes do not hinder movement and do not interfere with normal breathing.
It is better to turn the head to one side so that the person does not choke in case of possible bouts of vomiting.
Cover with a blanket, drink sweet coffee, which will increase pressure and return body temperature to normal.

The patient must be put to bed until the ambulance arrives.

If a downward pressure jump happened to a person for the first time, then before the ambulance arrives, you do not need to give him medicine. The drugs will be prescribed by the doctor, after a thorough examination.

In case of poor health hypotension, it is necessary to find out how long he took medication to normalize blood pressure. Usually people suffering from low blood pressure, constantly drink pills. Most often after breakfast and in the late afternoon (after eating). Therefore, if you skip the medication, there may be serious consequences and a significant deterioration in the condition. After taking the right pills, the state of health should return to normal even before the ambulance arrives.

Prevention

Lowering blood pressure brings many problems in daily life. To avoid this, it is important to adhere to the basic preventive measures:

establish a regime of work and rest, sleep for at least 8 hours;
lead a healthy lifestyle: douche, dousing, running, swimming, long walks in the fresh air;
moderate physical activity, after which the body receives a sufficient amount of oxygen;
adhere to proper nutrition (consume more vegetables, juices, fruits, exclude all fatty, spicy, salty, smoked), do not abuse alcohol and smoking.

It is important to adhere to preventive measures and consult a doctor in case of any negative deviations. This will allow you to detect problems in the body in time, and will also make it possible to prevent their further development.

Jumps in blood pressure downwards are not groundless. Usually these are body signals about the development of negative processes - a decrease in adrenal function, problems with the thyroid gland, serious disruptions in cardiovascular work. It is important not to ignore this condition and go to the hospital immediately.

The issue of low blood pressure in medicine is serious, since the consequences and causes of pathology have a significant impact on the health and performance of patients.

Hidden diseases or disturbances in the functioning of body systems - this is what low blood pressure indicates. The reasons for it are varied and depend on many factors.

In the medical literature, 12080 is considered to be the standard pressure for a person from twenty to forty years old. A slight decrease is not considered a deviation from the norm. Since for most people the “upper” working pressure is in the range from 110 to 130, and the lower one is from 70 to 90, with such figures they feel excellent and do not complain about their well-being. The consequences of this do not appear. begins when the patient, with numbers below 12080, experiences a deterioration in well-being, which manifests itself in:

violation of coordination of movements;
confusion of consciousness;
the presence of dark spots before the eyes;
general weakness;
tinnitus;
states close to fainting;
fainting;
sweating;
feeling of nausea;
lack of air;
paleness or blueness of the skin;
dizziness.

These symptoms are signs of several diseases, but if a person experiences more than three of them, it is highly likely that he has certain consequences.

It is dangerous when, under reduced pressure, the patient's heart rate is more than 90 beats per minute. In such cases, urgent medical care is needed, the consequences of not providing an ambulance are serious.

The table below shows the deviation limits for a healthy middle-aged patient leading a normal lifestyle.

Limits of deviation of arterial pressure

Depending on the etiological factors and the totality of manifestations of the signs of the disease, several types of hypotension are distinguished:

Orthostatic, with a sudden change in the position of the body. For example, quickly getting out of bed or sofa in the morning, a person feels tinnitus, darkness before his eyes, dizziness. The consequences are fainting and impaired spatial coordination. The reason is improper blood circulation and weakened activity of the heart. It manifests itself in women bearing a child, in patients with diabetes mellitus, in patients with a central nervous system disorder.
Postprandial, when the next meal becomes the cause of low blood pressure. The consequences are smoothed out by a fractional meal from the rejection of sugar;
VSD, observed in adolescents, children and women under twenty-five years of age. Systematic low blood pressure is sometimes noted against the background of impaired functions of the part of the nervous system that controls the activity of internal organs, glands and blood vessels.

Often all types of hypotension are present in the same patient.

As long as a person does not experience pathological symptoms during periods of low blood pressure, it is believed that the blood supplies enough oxygen to tissues and organs, the consequences and causes of low blood pressure are not serious.

For athletes, sometimes the numbers 9060 are considered to be working pressure. People with increased constant physical activity may also not notice a deterioration in well-being. An ordinary person after 30 years with such low rates is able to lose consciousness.

Individual numbers of normal pressure depend on the age of the patient and on his gender. From fifteen to nineteen years old, one of the root causes of low blood pressure is the restructuring of the hormonal background and the time of intensive maturation.

Both systolic (“upper”, indicating the strength of the ejection of blood into the aorta and the speed of its flow to the organs), and diastolic (“lower”, indicating pressure in the vessels, which is measured between heart contractions) pressure can be reduced. Experts believe that if the internal organs are healthy and there are no other diseases, then the causes of low heart pressure and its consequences should not be of concern. After a while, the symptoms will go away.

Causes of permanently low blood pressure

In medicine, there are two types of hypotension:

physiological (primary causes);
pathological (secondary causes).

They differ in the etiology of manifestation, in symptoms and consequences.

Physiological causes

Physiological causes are due to a hereditary predisposition to low blood pressure numbers that do not go beyond the normal range. Such hypotension manifests itself as:

individual norm - often depends on the physique of a person;
hypotension of high fitness - the vessels supplying blood to the muscles expand, causing a decrease in pressure, it is not required to increase it;
adaptive hypotension - occurs in residents of mountains, tropical and subtropical regions, the Far North.

This explains why the causes of low blood pressure do not indicate the presence of a serious pathology in the body, they appear imperceptibly, urgent treatment is not required.

Hypotension often occurs in a chronic form and suggests fatal consequences. Therefore, the causes of low blood pressure often remain unidentified. People do not pay due attention to their health and are not observed by a doctor.

During periods of low blood pressure, a person does not feel severe ailments and other alarming symptoms. He continues to be able to work and leads a normal life, adapting to the subtle manifestations of the disease.

Primary low pressure will not bother you if simple conditions are met. It is enough to adhere to a healthy lifestyle and streamline the daily routine in order to prevent undesirable consequences and not think about the causes.

The doctor will help determine the causes of low systolic and diastolic blood pressure, assess the consequences, and prescribe sedative medications. Self-treatment of low blood pressure is prohibited.

A good therapeutic effect in the treatment of physiological hypotension is given by gymnastics and swimming in the pool, hydro- and manual massage, reflexology sessions.

Pathological causes

Pathological hypotension is characterized by:

sudden weakening of vascular tone (collapse);
reduced supply of oxygen to the brain of the head (hypoxia);
paralytic vasodilation (shock).

The chronic form of secondary hypotension develops against the background of certain diseases. Reasons for lower numbers on the tonometer:

diseases of the heart and blood vessels;
pathology of the endocrine nature;
malfunctions of the digestive system;
anemia;
diseases caused by taking drugs;
consequences of head injuries;
diseases of the joints and spine.

The causes of constantly low blood pressure are existing identified or undiagnosed diseases. Symptoms go away after these diseases are identified and treated.

Why does intermittent hypotension occur?

Until recently, it was believed that periodic hypotension is the lot of older people. But in recent decades, cases of periodic low blood pressure in children, adolescents and young people have become more frequent.

The acute form of hypotension is dangerous for the development of a stroke. With a sudden deterioration in well-being, it is urgent to call an emergency ambulance team. In this case, the severity of the disease is determined not by blood pressure data, but by the rate of pressure drop.

Constantly repeated low numbers of the tonometer when measuring blood pressure in children indicate hypotension.

If the child does not experience constant heavy loads (when playing sports, for example) or this is not one of the ways the body adapts to environmental changes, then the following reasons can cause pathology:

heredity (more often on the maternal line);
disturbances in the activity of the endocrine system;
diseases of the heart and blood vessels.

In adolescence, the degree of psycho-emotional stress plays an important role when:

illnesses of a child are the consequences of the loss of a loved one or upbringing in an incomplete family;
he is brought up in unfavorable social conditions;
experiencing mental fatigue;
there is a history of hypodynamia.

In adolescents, a lag or advance in physical development is one of the root causes of low blood pressure. With age, all indicators are normalized, the consequences of low blood pressure cease to bother. At this time, it is important to provide him with the right regimen of the day and nutrition, protect him from stress and provide reasonable physical activity.

Running hypotension over time can become chronic and trigger irreversible consequences. Any complaints of children about ailments require consultation with a doctor.

In young men, low blood pressure is less common than in women.

The reasons are:

damage to the body by acute and chronic infections;
allergy;
physical and mental stress;
hereditary violation of the tone of blood vessels;
work in hazardous production;
alcohol abuse;
other factors mentioned above.

In women in the reproductive period of life, low blood pressure often occurs during childbearing and appears at the end of the II - beginning of the III trimester.

The risk is the fact that hypotension is asymptomatic. Of great importance for a pregnant woman is the daily monitoring of blood pressure.

Common causes of low blood pressure in women in position:

consequences of a malfunction of the hormonal system;
the formation of a bed in the uterus and placenta, retaining blood;
weakening of vascular resistance to blood flow;
inhibition reactions prevail over irritation reactions.

Women often ignore the signs of low blood pressure because they consider them normal for their situation. But it must be remembered that the causes and consequences of low blood pressure in the mother pose a threat to the normal formation and growth of the fetus.

In the elderly

Elderly people suffer from low blood pressure for various reasons. In addition to the congenital factor, hypotension can provoke:

taking medications;
poisoning;
weather dependence;
bleeding;
infections;
physical and emotional overload.

A common cause of intermittent hypotension in the elderly is a massive heart attack. The consequences are such that the necrotic-fibrotic processes occurring in the heart muscle reduce the strength of its contractions. Therefore, patients previously suffering from hypertension may become hypotensive.

With reduced pressure, experts recommend that older people do light morning exercises and breathing exercises. Regular exercise will help improve well-being, get rid of anxiety symptoms and prevent unpleasant consequences.

Effects

Prolonged low blood pressure in patients of any age causes many complications:

insufficient blood circulation of the brain, oxygen starvation impairs memory and reduces concentration, a person begins to experience constant weakness, quickly gets tired;
over time, hypotension can degenerate into hypertension - such a degeneration is difficult to treat, and former hypotension patients endure increased pressure more difficult than everyone else;
increases the likelihood of a heart attack, stroke, kidney failure;
during pregnancy, hypotension leads to oxygen starvation of the fetus, impairing its growth and development;
in schoolchildren, hypotension leads to a decrease in physical and mental activity;
an acute form of hypotension causes hypoxia and bleeding of tissues and organs;
possible fainting increases the likelihood of injury in a fall;
Frequent bouts of hypotension can cause a person to develop dementia or a stroke.

Conclusion

The reasons why low blood pressure is not considered a separate disease, but carries a health risk, lie in the etiology of its occurrence. Preservation of working capacity and mental activity at low numbers of blood pressure indicates the presence of physiological hypotension in a person. She doesn't need treatment.
Constantly low blood pressure figures, accompanied by painful symptoms, fatigue, fainting, indicate that the patient has other diseases that may not yet be detected at this point in time. Hypotension disappears when the underlying diseases that cause a decrease in pressure are detected and treated.
The consequences of hypotension are rarely fatal, but with constant low pressure, the general condition of the body worsens, the tone of blood vessels decreases, hypoxia appears, and meteorological sensitivity increases.

A fairly common pathology, characterized by a violation of blood pressure in the vessels and accompanied by a feeling of weakness, malaise, nausea, occipital headaches, a feeling of lack of oxygen, increased sweating, dizziness, is called hypotension.

Anyone can develop the disease, regardless of gender and age, but older people are more susceptible to its appearance. Therapy of the disease should be timely, or, to be more precise, permanent.

This is the only way to prevent the development of complications. From this article, you will learn about the symptoms of this pathological condition, as well as about the dangers of low blood pressure.

Hypotension is an ailment accompanied by a decrease in blood pressure below normal, observed in quite healthy person.

If we consider specific indicators, then they are everything below 100/60 mm Hg. However, generally accepted norms are one thing, but the characteristics of the body are another. Lowering blood pressure can be not only pathological, but also physiological.

Physiological is a completely normal state for people who are dominated by the influence of the PNS. They feel quite normal, but an increase in the level to normal is the reason for the deterioration of well-being.

So why is low blood pressure dangerous?

This condition, if left untreated, is fraught with the following complications:

vascular collapse;
orthostatic collapse;
impaired blood flow in the brain;
chronic hypoxia;
frequent fainting and the risk of serious injury;
hypertension (over time, chronic hypotension can transform into hypertension).

In addition, it is important to understand that it is not the low pressure itself that is dangerous, but the reasons for its occurrence. Identification of the true causes of the disease, their timely therapy and elimination are very important. This is the only way to prevent the development of dangerous diseases and critical conditions of the cardiovascular system and central nervous system.

A fairly common question is: “What is the danger of low blood pressure during pregnancy?”. So, if the expectant mother suffers from hypotension, the fetus may suffer from oxygen starvation (this is due to insufficient supply of oxygen to the placenta), which can cause disturbances in the development of its organs.

Women in a position with low blood pressure have a greater risk of developing toxicosis. In addition, during pregnancy, combined with hypotension, toxicosis can occur even in the third trimester and have a more severe course.

Moreover, low blood pressure in the fair half of society, bearing a fetus, can lead to preeclampsia. The insidiousness of hypotension in women in position lies in the fact that it is not easy to detect. Malaise and pain in the head, as well as other symptoms, can be considered banal fatigue or deviations during pregnancy.

In such cases, the care of the doctor should be maximum. Low blood pressure combined with a high heart rate can cause serious disruptions in the functioning of the heart and the cardiovascular system as a whole.

A rapid pulse is evidence of increased work of the heart, which quickly pumps blood, and in large volumes. A weak pulse with normal blood pressure is sometimes confused with hypotension. Although a weak pulse, combined with low blood pressure, is actually a symptom of other dangerous pathologies, for example, coronary artery disease.

Of particular note is the low diastolic pressure, indicating a low elasticity of the vessels, and often leading to stagnation of blood. The heart, in order to overcome this problem, has to work several times more productively, which in turn leads to an increase in systolic pressure.

As for physiological hypotension, this condition is in principle not dangerous.. On the contrary, hypotensive patients are less susceptible to the development of one of the most insidious pathologies of the 21st century, which provokes the development of stroke and heart attack - hypertension.

In addition, the vessels with physiological hypotension remain clean longer, which means that atherosclerosis does not threaten hypotensive patients. According to statistics, people with low blood pressure live many times longer than hypertensive patients.

There are actually plenty of reasons for the development of hypotension, the occurrence of pathology can be due to:

blood loss;
decrease in vascular tone;
decrease in the pumping function of the heart;
abuse of drugs that lower blood pressure, relax blood vessels and those that have diuretic properties;
dehydration;
malfunctions of the VNS;
genetic predisposition;
the presence of pathologies of the thyroid gland and central nervous system;
lack of sleep and frequent overwork;
sedentary lifestyle;
the presence of bad habits;
external influences: fluctuations in atmospheric pressure, high humidity.

As you can see, there are a lot of reasons for the development of this disease. Appropriate therapy is the best way to keep the heart working. In addition, people suffering from the disease need to regularly measure blood pressure with a tonometer. This will help prevent fainting and the development of critical conditions.

What pressure is considered low - symptoms and types of pathology by age

If you want to know what pressure is considered low, you should carefully read the article.

Despite the large number of possible causes for the development of hypotension, the mechanism of the onset of pathology can be due to four main factors:

decrease in minute and stroke volume of blood;
decrease in peripheral vascular resistance;
reduction of BCC (volume of blood circulation);
decreased venous blood flow to the heart.

You already know what pressure is considered low.

Now consider the main types of hypotension, hypotension can be:

essential or primary (lowering pressure acts as the leading clinical symptom);
secondary (develops against the background of other pathologies of the heart and blood vessels);
orthostatic (pressure drops sharply when changing the position of the body);
postprandial (lowering blood pressure after eating);
neurocirculatory;
adaptive or compensatory (people living in the tropics, highlands are susceptible to its development);
high fitness (sports hypotension);
acute (occurs quickly, lasts from several minutes to several hours, is characterized by a sharp deterioration in well-being and disturbances in blood circulation, life-threatening);
chronic (occurs and proceeds slowly, is relatively safe for life).

The answer to the question "What pressure is considered low?" simple. The norm for each person is often individual. And to understand the physiological hypotension or pathological can be on the state of health.

The norm is a pressure of 120/80 mm Hg. - This is for people from 20-40 years old. Normal figures for those aged 16-20 are 100/70, but they may be somewhat underestimated.

Hypotension is a decrease in pressure below 110-115 / 70 mm Hg. (in a man) and below 105-110 / 70-65 mm Hg. (for a woman).

In the elderly, hypotension is indicated by pressure below 140/80 (in men) and below 159/85 mm Hg. (among women).

Now you know what kind of blood pressure is considered low, which means you can quickly take action.

The main and constant sign of the disease is a steady decrease in blood pressure, hypotension is characterized by:

headaches. They can be pulsating, pressing;
dizziness;
blanching of the skin;
nausea;
flashing "flies" before the eyes;
decrease in working capacity;
drowsiness or insomnia;
irritability;
soreness behind the sternum (compressive, pressing, dull);
fainting and pre-fainting states;
functional heart murmurs;
a decrease in the quality of vision;
shortness of breath.

If you experience the above symptoms, seek the help of a qualified specialist immediately. He will conduct an examination and prescribe the right therapy.

Often, in addition to questioning, listening and examination, the following is prescribed:

load tests;
electrocardiography;
ultrasound examination;
dopplerometry;
blood and urine sampling for general and biochemical analyzes;
careful triple measurement of blood pressure.

Do not self-medicate, this can cause disastrous consequences.

What threatens low pressure: therapy and low blood pressure in pregnant women

You already know what threatens low blood pressure if it is not treated. In order to improve health, general condition, as well as prevent the development of complications, it is necessary to take the medicines prescribed by the attending physician on time.

If hypotension is symptomatic, that is, it is a manifestation of a different pathology, the underlying disease is treated, and then the pressure stabilizes.

In order to normalize the condition, as well as prevent the development of complications (you know what threatens low pressure), it is recommended:

give up bad habits;
observe the regime of work and rest;
do sport;
eat properly;
avoid a sharp change in the position of the body (horizontal or lying to vertical);
walk more.

As for drug therapy, the use of medications is often prescribed:

contributing to the improvement of hemodynamics, as well as an increase in vascular tone;
adaptogens (with weather dependence);
psychomotor stimulants: Sidnofena, Mezokarba, Sidnokarba;
analeptics: Cordiamin, Meridol;
contributing to the stimulation of the spinal cord: Securinina, Striznina;
at an ambulance: Mezaton, Veritol, Effortila;
contributing to the improvement of blood flow in the brain: Gutron, Regulton;
vitamins;

Hypotension or low blood pressure is a common disease characterized by various autonomic disorders.

According to statistics, about 20% of the population suffers from low blood pressure, while women suffer from this disease several times more often than men. In medicine, low blood pressure can often be found under the term "arterial hypotension", in which blood pressure is below 100/60 mm Hg. At risk for the development of this condition are people from 30 to 40 years old, but the disease can also affect the younger generation, including children. For some, hypotension is considered the norm, while for others, low blood pressure and its symptoms cause a lot of trouble with health, worsen the quality of life, and reduce performance.

Reasons for low blood pressure

The causes of low blood pressure are quite diverse and can be hidden both in the wrong way of life of a person and in his internal health.

1. Hypothermia of the body.
2. Internal infections.
3. The consequences of allergies.
4. Anemia.

5. Great loss of blood.
6. Regular stress, depression, nervous shocks.
7. Avitaminosis.
8. Hormonal disorders.
9. Diseases of the endocrine system.
10. Vegetative-vascular dystonia.

11. Trauma to the brain or spinal cord.
12. Exhaustion of the body.
13. Excessive exercise.
14. Wrong, unbalanced diet.
15. Alcohol abuse, smoking.
16. Diseases of the gastrointestinal tract.
17. Pathologies of the cardiovascular system.
18. Long-term use of potent drugs.

This is not the whole list of diseases and conditions. human body, which can lead to hypotension, but despite the etiological factor, low blood pressure and its symptoms cause a number of ailments in a person, constant fatigue, drowsiness, headaches and other unpleasant sensations. In medicine, primary and secondary hypotension are distinguished. The primary form of the disease manifests itself in functional disorders of the cardiovascular system and most often has a hereditary character, and the secondary form as a result of concomitant diseases. Like any other disease, arterial hypotension can occur in acute or chronic form.

Acute hypotension

Acute hypotension is a serious condition in which a person needs urgent hospitalization and long-term treatment. With the development of this condition, there is a sharp drop in blood pressure, which leads to hypoxia of the cerebral vessels, paralytic vasodilation. Basically, the condition of such patients is extremely severe, and the prognosis for treatment depends on the quality of medical care provided, as well as the rate of decrease in blood pressure. Untimely assistance in acute form of hypotension can lead to a heart attack, stroke, and even death.

Chronic hypotension

Unlike the acute form, chronic hypotension does not pose a threat to human life, but its symptoms should not be ignored either, since a person suffering from low blood pressure constantly feels any ailments that in one way or another affect overall well-being. At a more mature age, reduced blood pressure increases the risk of stroke and heart attack.

Symptoms

The clinical signs of low blood pressure are quite pronounced, but nevertheless, many ignore the symptoms of hypotension and may suffer from constant ailments for several years. The main symptoms of hypotension are:

Regular headaches, migraine attacks.
Dizziness.
Feeling cold.
Darkening in the eyes.
Increased sweating.
Noise in the head.
Breathlessness.
Violation of the heart rhythm.
Sleep disturbance.
Darkening in the eyes, "flies" before the eyes.

Headache with reduced pressure can be of varying intensity, appear intermittently, or be present all the time. There are cases that a headache with hypotension does not go away even after taking an anesthetic drug. People suffering from hypotension, even after 8 hours of sleep, wake up tired, it is difficult for them to concentrate on work, they often note absent-mindedness, forgetfulness.

Hypotonic patients cannot stand stuffiness, they are very sensitive to changing weather conditions. It is difficult for them to be among a large crowd of people, and with minor physical exertion they suffer from shortness of breath and pain in the heart, epigastrium. A characteristic symptom of low blood pressure is the appearance of frequent yawning, but it turns out not because the person did not get enough sleep, but because it is difficult for him to breathe and only yawning will allow him to take a deep breath.

Symptoms of hypotension can be caused by hypertension, but this often happens when a person suffering from hypertension has taken blood pressure pills, but has not calculated the dose or consulted with a doctor about taking antihypertensive drugs. This condition is considered extremely dangerous, since the pressure can drop very quickly, thereby causing the death of a person.

Low blood pressure - the symptoms, as well as the causes, are quite diverse, but if you ignore them or stop them with heart drops or painkillers, you should not expect a positive result, but you can’t avoid a deterioration in well-being.

Why is hypotension dangerous?

With reduced pressure, the internal organs of a person, including the brain, are poorly supplied with oxygen and other nutrients, which leads to the appearance of symptoms characteristic of hypotension. If a person does not take any measures to normalize blood pressure for a long time, the risk of ischemic stroke increases. In addition, a violation of blood flow affects the heart muscle, the death of its tissues occurs, as a result - myocardial infarction. Many people believe that only high blood pressure (hypertension) can cause a heart attack or stroke, but in fact, hypotension is also the cause of these conditions.

In older people, regular pressure surges cause mental disorders, senile dementia and other conditions. People suffering from low blood pressure feel constant fatigue, are prone to panic attacks, and often do not have the opportunity to work.

How to treat low blood pressure

Treating low blood pressure is no easy task. A person needs to change his usual way of life, devote as much time as possible to his health, monitor nutrition and the rhythm of life. An important step in the treatment of hypotension is nutrition. The patient is advised to consume healthy fortified foods as much as possible, to give up alcohol, fatty, spicy and fried foods. All foods that will be in the human diet should contain a sufficient amount of vitamins, minerals and other nutrients. If necessary, the doctor may prescribe a number of medications that will help eliminate the symptoms of hypotension, normalize blood circulation, and improve heart function.

1. Plant adaptogens. Preparations on a natural basis that will help stimulate the nervous system, improve the functioning of the cardiovascular system: extract of Eleutherococcus senticosus, tincture of ginseng, magnolia vine. Taking such drugs will eliminate drowsiness, improve brain function, and increase blood pressure.

2. Alpha-agonists. A group of drugs that eliminate stagnant processes in the vessels, make them more vulnerable, and normalize blood circulation.

3. Analeptics. Drugs that stimulate the nervous system. Such drugs are prescribed for angina pectoris. Their intake allows you to slowly increase pressure, normalize the work of the heart, relieve fatigue, improve brain function: Symptolum, Etimizol, Effortil, Caffeine-sodium benzoate.

If necessary, other medications may be prescribed to the patient. The course of treatment, dose, is prescribed by the doctor individually for each patient.

Prevention

Prevention of hypotension lies in a healthy and proper lifestyle.

Refusal of alcohol and smoking.
Healthy and wholesome food.
Regular exercise.
Timely and correct treatment of internal diseases.

By following the elementary rules, you can not only normalize blood pressure, but also improve the condition of the whole organism. Anyone who has experienced symptoms of low blood pressure should remember that in this condition, internal organs and systems experience oxygen starvation, so you should not ignore the symptoms of hypotension or self-medicate. Timely consultation with a doctor will help to avoid the unpleasant consequences of the disease, thereby improving the well-being and performance of a person.
