Which organ is responsible for human perspiration. how we sweat

What is sweating and why is it necessary for the human body? This is the process during which the production of liquid secretion by the sweat glands occurs. Sweat is colorless and odorless and is 98% water. Thanks to sweating, the water-salt level is regulated, the body is cleansed of toxins and does not overheat.

Why does a person need sweat:

The main task of sweat is to maintain normal temperature body, not exceeding 37 degrees. The resulting sweat comes out, evaporates and thus cools the whole body.
Sweat glands cleanse the body of toxins harmful products exchange, chemical substances included in drugs. In addition, toxic components such as arsenic, iron, and mercury come out with sweat.
Sweat glands sometimes take on a role sebaceous glands. For example, there are no sebaceous glands on the palms and soles of the feet, but there are sweat glands. They moisturize the skin and make it supple.
Maintains normal acid-base balance. The liquid secretion secreted by the sweat glands contains chlorides. They are formed in the body due to the consumption of salty and spicy food. Thanks to the release of chlorides along with sweat, the metabolism is normalized, and the balance of acid and alkali is established.

Sometimes during the examination, chlorides are found above the norm. This may indicate poisoning or dehydration of the body, become a signal of the onset of pathological processes in the organs of the urinary system.

Characteristics of the composition and mechanism of sweat production

How does sweating happen? The functioning of the sweat glands is under control nervous system. Physical activity, rise in body temperature, taking hot drinks or food, excitement cause a reaction of receptors in the skin, internal organs, muscles. nerve impulses enter the sweat glands and lead to a reduction in the ducts. As a result, sweat is released. It contains ammonia, creatinine, urea, amino acids, mineral salts, toxins, products metabolic processes. In total, there are about 250 substances excreted along with sweat.

Normally, sweating increases during heavy exercise. physical work, sports, in hot air, taking hot food or drinks, as well as during excitement and stress.

Healthy people produce sweat all the time, but with different speed and intensity. How much sweat does a person produce? Even in calm state and at a comfortable ambient temperature per day, the human body releases about 650 ml of sweat. During hot weather or when physical activity sweat glands produce up to 10 liters of liquid secretion. Throughout his life, a person loses about 17 thousand liters of liquid secretion.

There are two types of sweat glands:

Eccrine glands are evenly distributed throughout the body. They begin to function from birth. The main purpose is to regulate the temperature of the human body by moisturizing the skin. Sweat is colorless and contains salts and toxins.
In certain parts of the body (on the forehead, in the perineum, genitals) are apocrine glands. They are larger than the eccrine glands. The secret secreted by the glands does not get to the skin, but to the hair follicles. Their functioning begins only from the period hormonal adjustment in adolescence. Apocrine glands are not involved in regulating body temperature. Activated during fear, pain, physical activity. Sweat has a sticky texture, milky color. The composition includes fats, proteins, hormones.

It is noted that the body of a woman emits less sweat than the body of a man, even with the same physical activity. This is due to the greater activity of the apocrine glands. In addition, the body of men is larger and, accordingly, contains more water.

Suspicious changes

If everything is in order with a person’s health, then the sweat is colorless or whitish, without a specific smell. But sweat contains many lipids and other substances, which, when decomposed, become a favorable environment for the reproduction of pathogenic bacteria.

At various diseases the composition, color and amount of sweat changes. For example, in diseases thyroid gland iodine content may decrease or increase. The content of glucose in the liquid secretion secreted by the sweat glands increases in diabetes mellitus. Bile acids increase in liver pathologies.

The addition of the smell of ammonia or chlorine can indicate diseases of the kidneys and liver. At the same time, sweat stains remain on light-colored clothes. yellowish color. Traces of a bluish tint may appear as a result of inflammatory processes in the digestive tract.

Increased sweating is called hyperhidrosis. Distinguish between primary and secondary this disease. It is the secondary form of hyperhidrosis that is associated with pathological processes in the body:

Diseases respiratory system: pneumonia, bronchitis, tuberculosis. Therefore, if for last month several times there was an increased formation of sweat in a dream or in a calm state, you need to take an x-ray and consult a specialist.
oncological diseases in initial stage often accompanied by increased sweating, weakness, body temperature may rise. For example, malignancy adrenal glands. Ultrasound or MRI will help rule out the problem.
Problems with the thyroid gland (for example, hyperthyroidism) lead to changes in the hormonal background. There are failures in the thermoregulatory process.
Increased sweating may occur due to vegetative-vascular dystonia. There are changes in the nervous system, blood pressure changes. At the slightest adverse factors, sweat production increases.
Excess weight causes hyperhidrosis at night and daytime. As a result of excess kilograms, there is a load on everything internal organs, and they begin to work in enhanced mode.
diabetes changes hormonal background disrupts the heat transfer process.
A person can sweat a lot against the background of a rheumatological disorder.
The cause of the problem is diseases of the nervous system against the background of stress, depression, conflict situations, insomnia.
Nicotine and alcohol reduce the tone of muscles and blood vessels, the sweat glands begin to work incorrectly. Any movement leads to difficulty breathing, weakness, headaches and sweating.
Infectious and inflammatory processes in the body associated with a cold are accompanied by an increase in body temperature. Chills, weakness may be felt. Armpits, forehead, palms sweat not only during illness, but also during the recovery period after illness.
Prolonged and incorrect use of certain medicines leads to the fact that the body through sweat tries to get rid of harmful chemical compounds.
Diseases of the urinary system.

If the amount of sweat released has increased, then you should contact a therapist who will give directions for tests. Based on the results of the survey, the issue of further direction to narrow specialists. You may need the help of a neurologist, cardiologist, endocrinologist.

Therapeutic actions

Treatment should begin with preventive measures.

Personal hygiene should be carefully observed: take a shower, change Underwear every day.
Choose clothes only from non-synthetic, breathable material (linen, cotton, wool).
Menus should be based on natural products rich in vitamins and minerals. Ready meals should contain as little spices and salt as possible. Limited or completely eliminated carbonated drinks, coffee and alcohol.
If possible, stressful situations should be avoided.

Common means in the fight against advanced education sweat are:

taking drugs that calm the nervous system (Persen, Novo-Passit, Valerian);
the iontophoresis method cleanses the pores, improves the functioning of the sweat glands;
hormonal drugs stabilize the hormonal background;
Botox injections are prescribed, which block the work of the sweat glands.

Deodorants and antiperspirants can fight excessive sweating. The action of most of these cosmetics aimed at blocking the work of the sweat glands. Sweat continues to be produced, but has no way to come to the surface of the skin.

If a person physically works, worries, spends time outside in hot weather, then he begins to sweat intensely, which performs an important function. And what is sweat, what determines its color, smell and composition, why does it stand out, let's try to figure it out.

Sweat is not just a liquid, but the result of a kind of temperature regulation by the body, its purification from toxins and toxins. A person can die from overheating if sweat stops: but what it is and what role it plays is important to know.

Compound

Sweat has a liquid consistency. The main substances that sweat contains are sodium chloride, ammonia and urea. Together with sweat, the following trace elements are released: calcium, potassium, magnesium, sulfur, phosphorus, protein, milk, lemon and ascorbic acid.

Sweat is similar in composition to urine. In sick kidneys, sweat often smells very unpleasant.

In the sweat given off different areas contains varying amounts of sodium chloride. It is much more in the upper body, especially in the neck, much less on the hands and lower extremities.

Smell

An interesting fact is that a person feels the smell of sweat differently, since it contains volatiles- pheromones. These substances are not particularly noticeable by smell, but the human nose is able to catch them and send appropriate signals to the centers of the brain. This is how you unconsciously attract people of the opposite sex. By this elusive smell, some people are attracted to each other, while others feel hostility.

Color

Sweat can be white, transparent and even colored. It depends on what substances got inside the body, as well as on color-forming bacteria and various violations metabolic processes in the body.

Quantity

Man needs sweat, and every man sweats while he is alive.

How much sweat is excreted per day in a person?

The intensity of sweating depends on the state in which it is located:

if ambient temperature low, then up to 500 ml of sweat can be released per day, while the sweat glands function selectively;
it is worth increasing physical activity, raising the air temperature, as a person begins to sweat intensely; skin can stand out about 10-12 liters of sweat per day;
if the temperature in the sun or in the shade reaches 50 ° C, then per hour sweat is intensively released in a volume of 2 to 3 liters.

If a person is healthy, then, thanks to such intensive work of the sweat glands, there should be no overheating. It is known that in a lifetime the body releases about 20 thousand liters of sweat.

The smell is interconnected with a person's blood group and depends on the antigens produced by him.

Where are sweat glands located and how do they work?

Sweat glands are found in specific areas of the body.

These include:

armpits;
feet and palms;
face, lips;
neck area;
tip of the nose;
chin;
head;
back.

The glands of the sweating system are distributed in the reticular layer of the skin, resembling twisted tubules in shape. The gland is a body with an end and a sweat duct, in which a special pore can open to release fluid.

Sweat bubbles, before being released to the surface of the skin, are first separated by a membrane, moving towards the cell membrane, they merge and are excreted through the excretory duct.

Varieties of sweat glands

The sweat glands have different morphological features and functions. Distinguish: eccrine and apocrine sweat glands.

The first function constantly and are located on the surface of the skin. The latter are connected to the hair follicles, they function most actively in the period from 14 to 60 years.

Apocrine glands

Located near hair follicles. They can function where hair grows: in the armpits, on the head, inguinal region and on the areolas of the mammary glands. Where hair does not grow, these glands are absent. Basically, they actively function in adolescents who have reached puberty and adults, and in children and the elderly, the apocrine glands do not secrete sweat in sufficient quantities.

The individual smell of people depends on this gland. They also help improve skin moisture, protect it from drying out, and give it elasticity. They perform a cleansing function of removing all substances harmful to the body.

Most of the places of localization in the human body belong to the eccrine glands. They are found in almost all parts of the body: armpits, back, face, limbs.

These glands are very important for the harmonious functioning of the body as a whole and perform whole line positive features:

protect against overheating;
contribute to sweating during physical exertion, stress and excitement;
cleanse the body of accumulated toxins and harmful substances.

eccrine glands

This type of gland is considered the most active. They emit odorless sweat, which is necessary so that the body does not overheat, that is, they primarily perform the function of thermoregulation.

They secrete sweat constantly in the areas of the limbs. The most “sweaty part of them” is the area of the palms and heels, which we do not even notice. But it’s worth the body temperature to rise, start performing exercise or work, how they immediately react to these changes and the person sweats.

Types of sweat

Scientists have studied the composition of sweat, which comes out under different circumstances in the same person. It differs in the amount of sodium chloride salts, acids and trace elements.

For example, when stressful situations and agitation in many, the sweat acquires unpleasant odors and is excreted in the form of a thickish liquid. At the same time, only certain parts of the body sweat - hair, armpits, palms, feet.

Sports activities contribute to the fact that the body is cleansed of toxins and lactic acid is excreted.

With various diseases, the consistency of sweat also changes: a person often encounters thick and sticky secretions. And sticky sweat is a symptom of serious diseases, and this must be remembered. At the slightest change in its composition, it is necessary to seek the advice of a doctor.

Sweating in women and men

Men are known to sweat twice as much as women. This difference in quantity finds an explanation in ancient times. Men were mainly engaged in hunting, they had to make a lot of movements, which means more sweat. Therefore, since ancient times, it has developed so that the sweat glands of men work most intensively, and the smell in their armpits is more vivid than in women, since the apocrine glands are actively working.

But it is known that sometimes women sweat a lot:

during periods of intensive production of the hormone progesterone, especially in the 2nd half of the menstrual cycle;
in expectant mothers during pregnancy and after the birth of a child;
in women in middle age at the onset of menopause.

Sweating can be positive when thermoregulation of the body is necessary so as not to overheat, it is easier to endure physical exertion, stressful and exciting situations. But at the same time, excessive sweating, called hyperhidrosis, is considered pathological phenomenon which cannot be ignored.

Human sweat is a specific combination of salt, waste products, toxins and water that are excreted from the body. Depending on performance given function the body produces a release in order to stabilize general state of a person, as it works as a well-coordinated and trouble-free mechanism.

Definition and Benefits of Sweating

Sweating is a mandatory process that occurs in the body, as it performs a number of important functions in the form of regulation salt metabolism, eliminate harmful substances and to maintain optimal temperature body. The activity of the sweat glands is significantly increased in summer period, and in hot countries, the excretory system works in an enhanced mode.

Norms of manifestation excessive sweating observed at sharp rise temperature, increased physical activity, maturation of the egg in women during the onset of menopause and excessive body weight.

Increased sweating is not always unfavorable factor, and also brings certain benefits to the body. When the immune system fights the disease, the excretory system eliminates a large number of viruses through sweat. And also performed protective function skin and their necessary hydration.

If atypical sweating occurs, it is necessary to compare all suspicious symptoms and contact qualified specialist which will set exact reason pathology and prescribe the appropriate treatment regimen.

The chemical composition of sweat

The composition of sweat is based on percentage water about 99 and 1% of various substances in the form of impurities of ammonia, salts, urea. The study also determines ascorbic, lactic, lemon acid and residues of magnesium, protein, sulfur, calcium, potassium. In terms of content, the discharge is similar to urine and, with kidney pathology, a similar smell.

The active components of the composition of sweat do not change and have approximately the same ratio. After careful analysis, it was found that the secretions from different zones bodies contain various meanings substances. For example, in cervical area chlorides predominate, and in the legs there are impurities of calcium and magnesium.

An individual feature of sweating is the determination of nasal receptors by secreted pheromones. As a result, two people receive an unconscious sex drive at the level of the brain, which recorded the corresponding impulse.

Causes of a specific and unpleasant odor of sweat

The phenomenon of emitting an unpleasant odor of sweat in medical practice called bromidrosis and classify the forms of the disease:

apocrine type of pathology, accompanied by hard work sweat glands and the formation of a favorable environment for the development pathogenic microorganisms, which cause an unpleasant or specific smell of sweat;
Bromidrosis of the accrine type develops with overuse certain products or medicines containing poorly excreted active substances. In this case, it is recommended proper nutrition and avoidance of appropriate medications.

If the presence of a specific and unpleasant odor is noted during the release of sweat, then this phenomenon may indicate the presence of a number of diseases of various origins:

appearance pungent odor sweat is formed elevated acetone and development of oncological diseases;
the development of kidney dysfunction or pyelonephritis causes the appearance of a characteristic ammonia odor, as the excretory system begins to do the work for these organs;
the presence of vinegar smell appears with the development of diabetes;
education sour smell in chest can cause mastitis. In this case, it is necessary to contact a mammologist;
at malnutrition and violation of metabolic metabolism is characterized by the appearance of the smell of hydrogen sulfide;
change in the smell of sweat is formed with the occurrence of diseases of cardio-vascular system;
the presence of a gene predisposition to a specific smell of sweat;
change in the smell of sweat during menopause and during puberty of a woman.

The best solution to combat bad breath is timely examination for establishing possible diseases and prescribing further treatment.

If sweat smells of ammonia

If a specific smell of sweat resembling ammonia appears, a visit to the doctor and determination is necessary. possible cause stench formation. This pathology occurs during the manifestation of cystitis, inflammation genitourinary system, oncological processes.

Hormonal changes in the body during puberty can also cause the corresponding smell, as endocrine system subject to a heavy load, which leads to a lack or excess of iodine.

An unpleasant smell of ammonia may appear after increased physical activity, as the body loses large amounts of glucose and produces toxins that are excreted excretory system through the sweat glands.

Smell of sweat with cat urine

vital activity human body consists in the constant synthesis of proteins, fats and carbohydrates, in which various substances. especially important role amino acids play in the body, participating in many processes, and with their improper breakdown and disruption of the kidneys, Strong smell cat urine with perspiration.

Appearance characteristic odor also observed with liver dysfunction, leukemia, infectious diseases, intestinal obstruction, changes in the level of estrogens in a woman's body. Symptoms are observed in athletes who receive increased physical activity.

If suspicious symptoms were detected, then in this case, you need to immediately go to the hospital and conduct thorough examination. The body always responds to major changes and sends appropriate signals. Establishing a diagnosis for early stage course of the disease increases the chances of obtaining a favorable prognosis.

Sour or vinegar-smelling sweat

The presence of a pronounced smell of sweat mixed with acid and vinegar may have various reasons. To begin with, you need to consider external factors impact:

changes in the intestinal microflora and skin integument while observing a certain type of diet;
eating excessive amounts of certain foods (garlic, seafood, beans, yogurt, asparagus, red meats, cabbage, celery). When food is broken down, sulfides are released, which do not have time to be processed, which leads to the appearance of a characteristic odor;
disregard for personal hygiene large cluster emitted sweat is characterized by the appearance of an unpleasant and specific odor;
taking medicines ( nonsteroidal analgesics, antipsychotics and antidepressants).

The release of sour and acetic odor also occurs with the development of such diseases:

hormonal imbalances in female body with menopause and puberty;
development of mastopathy with the appearance of a sour smell in the chest;
progression of diabetes mellitus, since acidic compounds are in excess and are excreted through sweat.

The presence of the smell of dog with heavy sweating

The occurrence of such a specific smell of sweat as a dog indicates the presence serious illnesses inflammatory nature. Selection a large number harmful substances for the body that are not metabolized before normal state in combination causes the formation of stench.

This phenomenon is observed in acute respiratory diseases and education purulent process. Symptoms require immediate and speedy admission to the hospital, as it can lead to severe consequences. The state of the body in the presence of such pathologies has significant changes, so it is impossible not to notice them!

Appearance characteristic features strong sweating with a specific and unpleasant smell of sweat signal serious malfunctions in the body. As a prevention and warning serious diagnoses best to give necessary tests and visit an appropriate narrow-profile specialist.

The total number of sweat glands in humans reaches several million. Sweating is natural physiological process, characterized by the release of liquid to the surface skin. Sweat is colorless and has a salty taste.

Sweating plays an important role for the full functioning of the body. Sweat glands produce on the surface of the skin - the epidermis, a liquid secret. Its output to the outside normalizes water and salt balance in the body, regulates metabolic processes, cools the body.

Sweat renders beneficial effect on the skin to prevent dryness. Together with sweat, toxins leave the body and toxic substances, and evaporation of the secret normalizes thermoregulation.

Consider what human sweat consists of, how is it formed? What is the function of sweating, and what are the reasons excessive sweating in men?

Chemical composition

Human sweat contains a highly concentrated mixture of salts and some organic compounds. It consists of water, which in this aspect appears as a kind of solvent that removes other components from the human body.

The composition of human sweat is always different. He is affected age group person, state of health, place of residence, chronic diseases in history. If you taste the liquid, you feel a salty aftertaste. He is conditioned high concentration salts of chlorine. The intensity of taste is based on the state of health.

500 ml of sweat is released per day - this is the norm. Against the background of significant physical exertion, the figure increases to 1000-1500 ml in 24 hours. Increased sweating is observed in hot weather, during a deterioration in health due to any disease.

In addition to water and salts, the following compounds are included in the composition:

Lactic/uric acid;
Sulphuric acid;
Phosphates;
Calcium salts;
Urea;
Ammonia;
Amino acids;
fatty acids, etc.

People are wondering where does the specific and sometimes unpleasant smell in the armpits come from? In fact, sweat is 99% water and only 1% organic compounds, and it does not have a strong odor. However, in armpit and on the legs it smells, because these places are a favorable zone for the activity of pathogenic microorganisms.

With certain pathologies, the composition/color of sweat may change. For example, the secret becomes red (chromidrosis), which gives the impression that the person is bleeding through the skin.

Secretion analysis helps to establish the imbalance of mineral elements in the body.

Sweating functions

How is sweat formed in humans? The secret is produced by sweat glands, which are located throughout the body. The process of sweating is constant, never interrupted, almost all areas sweat. Only mucous membranes are not equipped with sweat glands. The intensity of the discharge depends on the place of residence, emotional and psychological state men.

The main function of the secret is thermoregulation. At low temperature regime when it is cold, the excretion of fluid slows down significantly. Against the backdrop of hot weather conditions, on the contrary, increases significantly. The secret does not allow the skin to overheat and burn.

The second function is the removal of excess from the human body. minerals. With a secret, not only water is released, but also organic components. It is especially useful to sweat for people with hypertension. breeding excess fluid leads to the normalization of arterial parameters.

Other functions of human sweat:

Thanks to sweating, toxic substances, toxins, infections come out of the body. At infectious disease doctors advise to sweat, and it's not just. This is believed to speed up the healing process. Sweat on the background elevated temperature body is useful because the liquid wets the skin, which reduces the temperature.
Sometimes the sweat glands take over the functionality of the sebaceous glands. For example, on the palms and soles lower extremities sebaceous glands missing. But sweat moisturizes the skin, prevents excessive dryness, and makes the skin supple.
Maintaining normal acid-base balance. The secret contains chlorides, which can be formed in the body when consuming spicy foods, table salt. Their removal from the body contributes to the normalization of metabolic processes.

The sweat glands are under the control of the central nervous system. Physical activity, an increase in body temperature, the consumption of hot tea or food, provoke "excitement" of the receptors of the skin, organs and muscles. Nerve impulses quickly reach the sweat glands, the ducts are reduced, which leads to the release of sweat.

Sweat contains about 250 components. Throughout life, a person allocates about 17,000 liters of secretion.

Sweat glands: types and localization

Sweat glands are located in the middle layer of the skin. Their ducts go outside and secrete a secret. The glands are localized over the entire surface of the body, but most of them are on the forehead, face, palms, soles, in the groin and armpits.

There are two types of glands that produce sweat. Endocrine glands cover 75% of the body, start working from the moment of birth. They regulate the temperature human body protect from overheating or cold. The sweat produced by these glands is colorless and contains salts and toxic substances.

Apocrine glands cover only 25% of the body. Unlike endocrine glands they are somewhat larger, located in certain areas: armpits, perineal area, forehead. These glands begin to work in puberty- the time of puberty, do not take part in the process of thermoregulation.

The secret of the activity of the apocrine glands is released not on the surface of the skin, but through hair follicles. Sweat can form due to excitement, nervous tension, pain syndrome or physical activity. The work of the apocrine glands is observed throughout life, but significantly slows down or even stops due to hormonal failure.

Apocrine glands produce a milky secretion, which contains lipids, protein and hormonal substances, volatile acids. The liquid contains many organic components that, when decomposed, provoke a specific odor. It is he who is the individual smell of a person that affects the opposite sex.

People do not perceive pheromones at the level of smell. In other words, they do not have any odor. However, a person’s nose feels them, after which it transmits an impulse to the brain.

This is how an unconscious attraction to a certain person is formed.

The pathogenesis of increased sweating

When a man is in good health, a colorless secret is produced or its shade is slightly white, the smell does not cause disgust. When there is a specific smell, appear on clothes, this indicates the presence pathological process in the body, or the influence of external factors.

In some pathologies, changes chemical composition, color and amount of secretion. For example, when endocrine disorders the concentration of iodine decreases or increases, which changes the color of the liquid. Against the background of diabetes mellitus, the amount of glucose in secret increases, and bile acids becomes more in violation of the functionality of the liver.

Spots of blue color on clothes signal the development of an inflammation focus in the digestive tract. Pathological sweating - hyperhidrosis. The disease is of primary and secondary nature. In the first case, the cause cannot be established, most often the etiology is due to heredity. Secondary hyperhidrosis develops due to the following diseases:

Pathology of the thyroid gland;
Oncology;
Obesity;
Hormonal imbalance;
Diseases of the respiratory system;
CNS disorders, etc.

When hyperhidrosis is a consequence of some disease, even the best does not help solve the problem. Necessary complete diagnostics to determine the exact cause.

Treatment is carried out by conservative and operative methods.

cool

Sweating performs essential function protect the body from overheating. Sweat glands are located on the entire surface of the body, their work is regulated sympathetic department autonomic nervous system. Intensity normal discharge sweat gland fluids different people is not the same. Therefore, excessive sweating (hyperhidrosis) is said only in cases where copious excretion sweat causes constant discomfort significantly reducing the quality of life.

Today we will talk about the conditions that cause hyperhidrosis.

Changes in the level of female sex hormones

Hyperhidrosis is often one of the manifestations of menopausal syndrome. A woman periodically experiences hot flashes to the face, neck and upper chest, accompanied by increased heart rate and sweating. This can happen at any time of the day or night. If attacks occur no more than 20 times a day, the situation is considered normal and does not require medical intervention. When Others Join Hyperhidrosis unpleasant symptoms(pain in the head or in the chest, increased blood pressure, numbness of the hands, urinary incontinence, dry mucous membranes, etc.), a woman should consult a gynecologist regarding compensatory therapy.

Excessive sweating of the whole body is also characteristic of the first two trimesters of pregnancy. It occurs against the background of hormonal changes and is considered normal. Hyperhidrosis in the third trimester is associated with an acceleration of metabolism, the accumulation of large amounts of fluid in the body, or a set of excess weight. warning signs may have an ammonia smell perspiration and the appearance of white marks on clothes, indicating violations of the kidneys.

Pathology of the thyroid gland

Hyperhidrosis is one of the symptoms of abnormally high production of thyroid hormones (hyperthyroidism). It occurs with the following diseases:

nodular toxic goiter;
Graves' disease (diffuse goiter);
subacute thyroiditis.

Excessive sweating caused by wrong work thyroid gland, sometimes manifested in pituitary tumors. If hyperhidrosis is combined with a sharp weight loss on the background increased appetite, hand tremors, disturbances heart rate, irritability and anxiety, it is urgent to consult an endocrinologist.

fluctuations in blood glucose levels

Excessive sweating often occurs with diabetes. In this case, it is associated with a violation of thermoregulation. Diabetes of any type leads to destruction nerve endings, as a result of which it becomes impossible to adequately transmit signals to the sweat glands. In diabetics, hyperhidrosis primarily affects upper half body: face, neck, chest and abdomen. Characteristically increased secretion fluids at night.

Hyperhidrosis can also indicate an insufficient amount of glucose in the blood (hypoglycemia). In patients diabetes the cause of the problem is usually a violation of the diet or an overdose of hypoglycemic medicines. Healthy people sometimes lack glucose after heavy physical exertion. With hypoglycemia, cold clammy sweat appears mainly on the back of the head and back of the neck. The attack may be accompanied by dizziness, nausea, trembling, and blurred vision. To quickly get rid of the malaise, you need to eat something sweet (banana, candy, etc.).

Problems with the heart and blood vessels

Almost all diseases of the cardiovascular system are accompanied by hyperhidrosis to one degree or another. Increased sweating is inherent in the following pathologies:

hypertonic disease;
atherosclerosis;
obliterating endarteritis;
angina;
transient ischemic attack;
vascular thrombosis.

In addition, sweat glands increased load work in people suffering from pericarditis or myocarditis.
