Our body is arranged so cunningly and wisely that the slightest malfunctions in the work of some organs and systems immediately send SOS signals. For example, what can the constant thirst that overcomes a person mean?

A simple feature of the body or a harbinger of some kind of disease? There are several reasons for this, let's try to figure it out.

1. Lack of fluid.

This most often happens during the hot season. If a person drinks little, the body "turns on" a kind of protective mechanism that saves him from dehydration. At the same time, the mucous membrane of the mouth dries up, facial features become sharper, eyes sink, the skin becomes dry and flabby. The kidneys “save” precious moisture, so a person very rarely visits the toilet.

What to do: in the heat, with increased physical activity, heavy sweating, bleeding, vomiting and diarrhea, you need to drink much more. As soon as the water balance in the body is restored, the thirst will pass.

2. Diabetes.

Constant thirst and frequent urination are the first symptoms of an insidious and formidable disease. This is due to an imbalance of hormones that regulate water-salt metabolism.

What to do: take tests to find out the level of sugar in the blood, and if it is elevated, immediately contact an endocrinologist who will prescribe the appropriate treatment, in particular, glucose-lowering drugs.

3. Lots of hormones.

Strong thirst often occurs when increased function parathyroid glands (they are located on the neck near the thyroid gland). The disease also causes other changes: pain in the bones is felt, fast fatiguability, muscle weakness, sudden weight loss, teeth may fall out. Calcium leached from the bones turns the urine white.

What to do: contact an endocrinologist who will prescribe the appropriate treatment.

4. Problematic kidneys.

Thirst is almost always noted in pyelonephritis, glomerulonephritis, hydronephrosis, polycystic kidney disease, renal failure and other diseases. This is due to the fact that the affected kidneys are not able to retain water, resulting in an increased need for fluid. Moreover, thirst persists even when the amount of urine excreted decreases and edema appears.

What to do: Be sure to contact a nephrologist. Ignoring the disease, you can wait for serious complications, when only hemodialysis or kidney transplantation can help a person.

5. neurological problems.

Sometimes intense thirst occurs after brain injuries or neurosurgical operations. The disease, as a rule, occurs abruptly, the patient can even indicate the day and hour when this happened. diabetes insipidus develops. At the same time, patients can drink ten to twenty liters of water per day, but the thirst still does not go away. It's all about the deficiency of hormones that limit urination.

What to do: immediately consult a doctor, preferably a neurologist.

6. Medicines are to blame.

Taking certain drugs causes dry mouth, so a person drinks a lot. So, in particular, there are some drugs to lower blood pressure, antihistamines, medicines for bronchial asthma and etc.

What to do: Talk to your doctor about whether these drugs can be replaced.

7. Thirst on "nervous grounds".

Such "psychological" thirst is observed most often in women. In addition, whims, irritability, tearfulness, and a depressed mood are added to it.

What to do: try to "deceive" your body, wet your lips, lean into the water and make a few swallowing movements, rinse your mouth. Sometimes this is enough to make such pseudo-thirst disappear.

The human body is complex system which tends to self-regulate. Our brains are designed in an amazing way: when people are deficient in certain substances, they have a desire to eat or drink something with their content. Constant feeling thirst and dry mouth just becomes one of these manifestations.

Ways to remove fluid

The human body consists of 80% water. It provides the course of all reactions occurring in the body and performs the function of a natural solvent. Therefore, maintaining its level is necessary to ensure normal life.

If an adult can live up to 30 days without food, then in the absence of fluid, death occurs within 3 days. This is due to the fact that water is rapidly excreted from the body in the process of life, and therefore its reserves must be constantly replenished.

The main ways of removing fluid can be called such systems of the body:

• excretory system. The fluid is constantly filtered through the kidneys, depositing excess salts and toxins in them. The liquid goes through two filtration cycles: during the first, several liters of primary urine are formed, and during the second, its amount is reduced to several hundred ml. This fluid is already excreted from the body. With an excess amount of urine and frequent urination, it is worth undergoing a diagnosis in order to exclude diseases of the excretory system organs.
• Respiratory system. In the process of exhaling air, a large amount of substances are removed from the body - these are pollution that got into the lungs, and carbon dioxide that was formed in tissues and organs. Also, a large amount of liquid evaporates from the surface of the mucous membrane - it humidifies the air inhaled by a person. And, accordingly, with exhalation, this liquid leaves the human body.
• Gastrointestinal tract. The intestine becomes the main source of fluid excretion - normally, water from food is absorbed through its walls. With the development of an infection or any disease of the digestive system, the normal process of splitting nutrients is disrupted. This causes the acceleration of the excretion of food masses, for which the absorption of fluid through the intestinal walls stops. As a result, this liquid contributes to the faster removal of toxins from the body. This process is manifested by diarrhea.
• Skin. On the surface of the skin there are a large number of small sweat glands. Through them naturally thermoregulation takes place. With the release of sweat, the body temperature, if necessary, decreases. This helps to cool the surface of the skin. excessive sweating can also be a symptom of the disease.

Important: Dehydration of the body begins with a loss of fluid in the amount of 1% of body weight. With a loss of 10%, vital processes slow down so much that a person falls into a coma. Loss of more than 20% of fluid causes death.

With a decrease normal level hydration, the body tries to replenish it naturally. Therefore, with excessive loss of fluid, a person is constantly tormented by thirst and a feeling of dryness in the mouth.

Causes of thirst and ways to eliminate it

The feeling of dry mouth and debilitating thirst are familiar to many people. These anxiety symptoms talking about water scarcity.

This condition may have several causes.:

• Dehydration. Often the cause of dry mouth and intense thirst is a sharp decline the amount of fluid in the body. It may be due to excessive consumption of alcoholic beverages and coffee. Excessive physical activity can also provoke a feeling of dry mouth, heat, diarrhea or blood loss. All these conditions lead to a decrease in the amount of fluid in the body and, as a result, dry mouth.
• Diabetes . With diabetes, dry mouth persists even after drinking a lot of water. And, despite the fact that a person is constantly tormented by thirst, he often visits the toilet. This condition is additionally accompanied by dizziness, weakness and a sharp change in weight.
• Diseases caused by hormonal changes. With excessive activity of the parathyroid glands in the human body, it leads to the excretion of a large amount of calcium. This causes a loss of moisture, which is manifested by a feeling of dry mouth and constant thirst. At the same time, muscle weakness, discoloration of urine, and bone pain may additionally appear.
• The use of drugs. Long-term use of various medications can also cause dry mouth and thirst. These drugs include diuretics, antibiotics, expectorants and antihistamines. If thirst appeared just after the start of taking medications, it is worth consulting with your doctor so that he prescribes other drugs, and the patient gets rid of the feeling of dry mouth.
• kidney disease. The kidneys are one of the main organs responsible for removing excess fluid from the body. If their function is impaired, dehydration is observed, dry mouth appears, which may be accompanied by excessive swelling, pain in the kidney area. If you experience constant thirst and a feeling of dry mouth, which are accompanied by the appearance of edema, you should immediately consult a doctor.

Thirst and pregnancy

The constant feeling of thirst and dry mouth during pregnancy may be due to insufficient fluid intake. Normally, during pregnancy, a woman needs to consume 0.3 liters of water more than before carrying a child. This increase in the amount of fluid is due to the fact that the fetus needs water for development, since its body is in the stage of active development.

In this case, the total amount of water drunk should not exceed 2 liters per day. Otherwise, even in spite of thirst and a feeling of dryness in the mouth, excessive swelling will appear.

During pregnancy, a large amount of angiotensin is produced in the human body. This is a special protein that is produced when the mineral balance in the body changes.

Angiotensin production begins at 26 weeks and may continue until the end of pregnancy. Protein stimulates an increase in the load on the kidneys, which leads to frequent urination, dry mouth, constant thirst.

Relieve dry mouth and thirst

To eliminate this bad sign, it is necessary to first identify its causes. If constant thirst provokes a violation of the water-salt balance caused by dehydration, a person is recommended to drink liquids containing electrolytes. Such a liquid helps to quickly normalize the water-salt balance and get rid of puffiness.

But what about a person who wants to drink all the time - regardless of how much he has already drunk? How much is warning sign? What diseases are evidenced by constant thirst, let's talk further.

Doctors call the syndrome of constant thirst polydipsia. it pathological phenomenon, which indicates a clear lack of fluid in the body. Fluid loss can be associated both with the above phenomena, and after disruption of the body (vomiting, increased sweating, diarrhea).

Those diseases, which are evidenced by constant thirst, can be quite serious, so this alarming "call" should not be ignored. Most often, thirst is provoked by diseases of the liver or kidneys, infectious diseases, increased blood sugar, improper water metabolism, burns. In addition, doctors also add what diseases to think about when they appear. constant desire drink. These are diseases mental nature, nervous disorders, schizophrenia, obsessive and depressive states, the feeling of thirst often occurs after head injuries, possibly resulting in a concussion.

Natural Causes of Thirst

Evaporation of water from sweat. The body releases sweat during exercise or when the ambient temperature rises. If you're sweating and now you're thirsty, that's fine. Don't worry - it's normal reaction. Beware of excessive sweating. For different people, it can be considered normal different level sweating. Sweating should be considered excessive if you observe a sharp increase in sweating compared to your usual level. Such a change can be a symptom of a number of diseases of the lungs, kidneys, heart, nervous system, immune system, inflammatory processes. Inflammatory processes can be determined by elevated body temperature. Diagnosis of other factors will require a visit to a doctor and analysis, laboratory tests.

High body temperature can cause thirst. Take your temperature and see a doctor if it's elevated.

Very dry air. If the air around is very dry, then the body loses moisture and there is a strong desire to drink. Air conditioners are especially dry. If the thirst disappears when the humidity normalizes, then the reason is not your health, but the dry air. Drink more water. Get plants. Plants evaporate a lot of water, raise humidity.

Soft water. If you drink water with an insufficient content of mineral salts, you may experience constant thirst. Mineral salts contribute to the absorption of water and its retention in the body. Try to drink bottled water with a normalized mineral content, or, if this is not contraindicated for you, then mineral water of the sodium chloride group with a small amount of salts. If it does not help, then the reason is not in the water, but in something else.

Hard water, excess salt in the diet. An excess of mineral salts can also cause thirst, since salts, if they are in excess, attract water, preventing its normal absorption by cells. The kidneys excrete excess salts with water.

Diuretic food. Some foods are diuretic. For example, coffee. I can't drink coffee at all. After that, I die of thirst. Diuretic products help remove water from the body. There is dehydration and a desire to drink. Try to give up such food for a while. If the thirst is gone, then everything is fine with health, such thirst is safe, you can return to your usual food intake, drink water for health.

Spicy or salty food. Spicy or salty foods simply irritate the mouth and throat. Thirst arises reflexively. Give up such food for a while. If the thirst has passed, then there is no point in worrying further. You can return to your normal diet. Drinking spicy and salty foods with plenty of water is completely normal.

Causes of pathological thirst

Here are some of the most common causes of abnormal thirst (polydipsia):

• Lack of water and salt in the body (for example, as a result of sweating, diarrhea, vomiting).
• Taking certain medications.
• Excessive consumption of alcohol, caffeine and salt.

Possible diseases

Thirst can be a sign of a more serious condition and is caused by:

• Hyperglycemia (high blood sugar);
• Diabetes;
• diabetes insipidus (impaired water metabolism);
• Kidney disorders (for example, Fanconi syndrome);
• Dehydration;
• Liver disease (hepatitis or cirrhosis);
• Bleeding (for example, in the intestines);
• burns or infection;
• Head injury;
• Mental disorders (schizophrenia, obsessive states that cause thirst).

Medications

Certain medications can make you thirsty.

• Diuretics. Used in the treatment of hypertension, diabetes and heart failure. Also prescribed for edema and diabetes insipidus. They lead to frequent urination and dehydration.
• Tetracycline antibiotics. Used to treat bacterial infections. Remove sodium from the body.
• Lithium. Used to treat bipolar disorder and other psychiatric disorders.
• Phenothiazine. Used to treat schizophrenia and other mental disorders.

How to get rid of constant thirst?

Try to drink before you feel a strong urge to drink water. To prevent thirst from making itself felt, drink half a cup of pure water every hour. Increase your fluid intake if you are for a long time in a dry, warm room. It is recommended to drink eight glasses of liquid throughout the day.

Watch your urination. To rid your body of dehydration, you should drink such an amount of liquid that the urine will not be dark or too light in color. An indicator of sufficient fluid content is urine of a normal, moderate yellow color.

Drink clean water during physical work, sports training. During hard work, a person loses from 1.5 to 2 liters of fluid and only after that feels thirsty. Therefore, to prevent dehydration, drink half a glass of water 15 minutes before starting work or playing sports. Then drink water every 15 minutes. during, and 15 minutes after the end of work or training.

If the thirst is constant, you drink a large amount of fluid per day, but you still want to drink, you need to take a blood test for high sugar. Since diabetes can be the cause of constant thirst, you need to go medical examination, and if necessary, adhere to a special treatment program, follow a diet.

So we talked about why there is a constant thirst, the reasons for how to get rid of told. When the above symptoms appear, you should immediately seek advice from an endocrinologist or therapist. If you want to drink after a head injury, then you need to go to an appointment with a neurologist or traumatologist. Having established the cause of constant thirst, it is easier to get rid of this obsessive state. Be healthy!

Thirst: causes of development, diagnosis and treatment of comorbidities

From a physiological point of view, strong thirst or polydipsia is the body's response to a violation of the ratio of water and various salts contained in its tissues. A high concentration of salts in blood plasma and tissue fluid adversely affects osmotic pressure providing the shape of cells and their normal vital activity. As a result, skin elasticity is lost, facial features become sharper, a person may be disturbed by headaches and dizziness. Therefore, the lack of fluid in the cells causes a very strong desire of the body to restore the water balance.

The feeling of unquenchable thirst or polydipsia decreases or disappears when drinking large volumes of water - more than two liters per day (for an adult).

Causes of intense thirst

Polydipsia occurs due to the intense activation of the drinking center located in the brain. This, as a rule, can be caused by physiological or pathological causes.

Physiological causes of extreme thirst include:

1. Increased loss of water through sweat during intense exercise or heat.
2. Dehydration of the body in case of poisoning, accompanied by diarrhea.
3. Intoxication of the body with alcohol breakdown products, for the natural withdrawal (through the kidneys) of which a large amount of water is required.
4. Too dry air in the room, because of which the body has to lose moisture. This situation usually occurs in heating season and when operating air conditioners. To solve the problem with the normalization of humidity, you can use humidifiers or indoor plants that increase the level of moisture in the room.
5. The use of spicy, salty or smoked foods, as well as the abuse of coffee and sweet soda.
6. Consumption of water with an insufficient content of mineral salts, the so-called soft water. It is thanks to mineral salts that the body absorbs and retains water better. Therefore, it is advisable to choose to drink mineral water sodium chloride group with a sufficient salt content.
7. The consumption of water with excessive salt content also negatively affects the body's water balance, since salt in excess prevents cells from absorbing water.
8. Eating foods and drinks that have diuretic properties. These foods cause dehydration and a strong desire to drink.

If the physiological causes of polydipsia are at least temporarily excluded, but the feeling of thirst does not stop, you should immediately contact a therapist and undergo all the necessary studies, since the causes of this problem may be pathological.

Pathological causes of polydipsia include:

1. The development of diabetes mellitus, which at first is always accompanied by frequent and copious excretion urine, which in turn dehydrates the body and causes thirst. The following accompanying symptoms may also indicate the development of this disease: skin itching, dizziness, recurrent headaches, sudden weight gain.
2. Diabetes insipidus is a violation of the endocrine system, which is accompanied by an intensive excretion of water through the kidneys (several liters of light-colored urine per day). With this problem, you should consult an endocrinologist. The main reasons causing development diabetes insipidus, are neurosurgical interventions or brain injuries.
3. Hyperparathyroidism is a malfunction of the parathyroid glands, in which bone tissue calcium is washed out. And since calcium is osmotically active, it “takes” water with it. Other symptoms may indicate the development of this endocrine disease:
   • urine is white;
   • sudden weight loss;
   • muscle weakness;
   • increased fatigue;
   • pain in the legs;
   • early tooth loss.
4. Kidney disease, which is usually accompanied by swelling, dry mouth, problem urination. Sick kidneys are not able to retain in the body the volumes of water necessary for its full-fledged life. The kidneys are most often affected by disorders such as acute and chronic pyelonephritis, primary and secondary wrinkled kidney, glomerulonephritis, hydronephrosis and chronic renal failure.
5. Chronic stress and nervous tension, as well as more serious mental disorders (obsessive-compulsive disorder, schizophrenia). Mental problems can provoke a violation of the thirst regulation center, which is located in the hypothalamus. According to statistics, this cause of intense thirst is most often encountered by women. As a rule, symptoms such as drowsiness, tearfulness and irritability can indicate the development of a mental disorder simultaneously with an unquenchable desire to drink.
6. Brain tumor, stroke and other focal lesions and brain injuries that can disrupt the hypothalamus, which is responsible for the central regulation of thirst.
7. pathological problems with gastrointestinal tract(GIT), accompanied by constant hidden bleeding, due to which there is often a feeling of thirst. Most often, polydipsia is caused by an intestinal tumor, hemorrhoids, etc. To diagnose the presence of hidden bleeding, first of all, you need to take a stool test.
8. Generalized hyperhidrosis - excessive sweating pathological. This disorder may indicate the development of diseases such as:
   • thyrotoxicosis;
   • acromegaly;
   • pathological menopause;
   • Hodgkin's lymphoma;
   • other disorders of the endocrine system.

Increased non-physiological sweating is the reason for a visit to the endocrinologist.

Diseases that may be indicated by the presence of intense thirst in combination with nausea

Most often, these symptoms are combined with:

In addition, the combination of polydipsia and nausea may indicate diseases, the development of which causes other accompanying symptoms:

1. A white coating on the tongue, belching, heartburn, dryness and bitterness in the mouth may indicate disorders in the gallbladder (cholecystitis, pancreatitis or gastritis). The same symptoms may occur during the use of certain antibiotics and antihistamines.
2. Burning gums and tongue metallic taste in the mouth, combined with nausea and thirst, can disturb gum disease.
3. Heartburn, a feeling of fullness and pain in the stomach area may indicate the development of gastritis of the stomach.
4. Violation of the body's water balance and dry mouth, bitterness, white or yellow plaque on the tongue indicate a violation of the thyroid gland.
5. Nausea, polydipsia in combination with other painful symptoms in the gastrointestinal tract may indicate the development of diseases of the central nervous system (psychosis, neurosis, amenorrhea, neurotic disorders).

It is important to understand that if thirst and nausea bother you for several days, you cannot cope without medical help. You should consult a doctor who will professionally assess the associated symptoms; pass all the necessary tests and pass a series of diagnostic studies. All these activities will help determine what kind of pathology you are suffering from.

Intense thirst and drugs

It is worth noting that polydipsia can be caused by taking medications that help remove moisture from the body. It can be:

In addition, some medications can cause excessive sweating and thirst (for example, acetylsalicylic acid), which is usually listed on their side effects list.

Among the popular drugs that make many patients thirsty are Metformin, an antidiabetic agent used in the treatment of:

1. Diabetes mellitus type 1 and 2.
2. Impaired glucose tolerance.
3. Gynecological diseases.
4. Endocrinological disorders.

Also, this drug is used to normalize body weight, since it active substance reduces insulin production, significantly reducing appetite. During the use of Metformin, a carbohydrate-free diet should be followed, otherwise side effects from the gastrointestinal tract are possible - nausea, vomiting, liquid stool, metallic taste in the mouth.

It is important to understand that with a competent approach to the use of Metformin, in compliance with all the recommendations specified in the instructions for this drug, any side effects are excluded, including dehydration and thirst.

Polydipsia during pregnancy

As you know, the human body is 80% water, the sufficient presence of which in each of its cells guarantees normal functioning the whole organism. During pregnancy, every woman is exposed to increased loads and trials. Very often the body expectant mother suffers from thirst and water imbalance, which can cause a slowdown metabolic processes, and lead to pathological changes in the body of the mother and the development of the fetus.

The main causes of severe thirst in pregnant women:

1. Formation of amniotic fluid. With each week of fetal development, the volume of amniotic fluid increases, which means that the amount of water needed increases, and, accordingly, polydipsia increases.
2. During the first trimester of pregnancy, a woman needs more fluid to remove toxins and waste, since the undeveloped organs of the fetus are not yet able to neutralize them on their own.
3. Structure changes circulatory system that occur up to the 20th week of gestation. Since the body of a pregnant woman has to work more intensively, there is an increased need for fluid, the lack of which leads to the fact that the blood thickens. With a thick consistency of blood, the risk of blood clots, ischemia and other pathologies increases of cardio-vascular system.
4. Change in food tastes. As a woman tends to overindulge in sweet, salty, spicy, or fatty foods during pregnancy, she has an increased need for extra fluids to help digest and remove excess salt from the body.
5. Bacterial and viral infections, intestinal and respiratory disorders can also cause polydipsia.
6. Gestational diabetes mellitus, the development of which is accompanied by thirst and dry mouth. This disease can be diagnosed with urine and stool tests.

It is worth noting that there are situations when, according to urine tests and accompanying symptoms, a pregnant woman needs to reduce the amount of fluid consumed. Otherwise, preeclampsia may develop and the risk of premature birth increases.

Diagnosis of polydipsia

Since polydipsia can be a symptom of a rather serious pathology of some body system, the diagnosis of thirst is a very complex and lengthy process, which includes:

• questioning the patient;
• inspection;
• delivery of laboratory tests. As a rule, a blood and urine test is done first. If the cause of increased thirst is not established, then tests for hormones, liver and kidney tests are prescribed;
• hardware study of individual organs of the patient (radiography of the lungs, ECG, ultrasound, etc.).

Note! If thirst is non-physiological in nature, then the body, in most cases, is first diagnosed for the presence of diabetes or diabetes insipidus, as well as disorders in the functioning of the kidneys or the cardiovascular system, since these are the problems most often found in patients.

Prevention and treatment of polydipsia

The main task of the prevention and treatment of increased thirst is to restore the water-salt balance, as well as to identify and eliminate the factors that cause the body to feel unwell.

1. Increase the amount of fluid you drink to two liters per day. So that the problem of increased thirst does not make itself felt for a long time, it is advisable to drink half a cup of purified water every hour.
2. Normalize the humidity in the room where you are, because dry air increases thirst. To increase the humidity, you can start houseplants Or buy a humidifier.
3. Refuse to consume fatty, spicy and salty foods, various dietary supplements and drugs that cause thirst, as well as snacks, coffee, alcoholic beverages, sweet soda.
4. Get rid of bad habits (smoking).
5. Half an hour before the start of training or other physical activity, drink half a glass of water.
6. Monitor the quality of your urination. If the urine is too light or dark in color, it is necessary to reconsider the amount of fluid consumed. With a normal water content in the body, urine has a moderate yellow no strong odor.

If the physiological factors that cause thirst are completely eliminated, but dehydration does not stop, you should immediately go to a general practitioner or endocrinologist at the place of residence, who will prescribe all the necessary tests and conduct a thorough examination of the body. If there is a head injury, after which increased thirst began to be observed, it is necessary to seek advice from a traumatologist and a neurologist.

It is important to understand that heightened feeling thirst is not the cause, but a symptom of some disease. And that it is quite possible we can talk about very serious illnesses. Therefore, the appearance of polydipsia should never be ignored.

Evtushenko Oleg, endocrinologist

intense thirst

Constant thirst is a symptom that belongs to the group of non-specific, since it can accompany a large number of a wide variety of diseases. Although the basis etiological factors constitute pathological conditions, dryness in the oral cavity and thirst can be formed against the background of completely harmless conditions. For example, the period of bearing a child or playing sports.

It is unacceptable to consider the feeling of thirst as the only clinical manifestation. It is mandatory to pay attention to other signs that may complement it. Often these symptoms are - the appearance of plaque on the tongue, weakness and nausea, bad taste mouth and dizziness.

Adequate diagnosis of constant thirst, i.e., identifying the causes of its occurrence, requires integrated approach and in addition to primary diagnostic measures includes laboratory and instrumental examinations patient.

Therapeutic measures will completely depend on what disease has become a provocateur of such a symptom, often conservative methods are sufficient.

Etiology

First of all, it should be noted that the most acceptable amount of liquid that a person should drink per day is two liters. In some cases, it is the lack of water that leads to the fact that a person suffers from constant thirst. Therefore, it is necessary to strictly monitor the volume of fluids drunk, especially in children and the elderly, as well as in malnourished patients.

The reasons for constant thirst will be dictated by the methods of removing fluid from the body. This can happen through:

• kidneys and intestines;
• skin covering;
• lungs and mucous membrane of the upper respiratory tract.

Loss of water through the kidneys occurs against the background of:

• uncontrolled intake of diuretics;
• abuse of drugs for weight loss;
• excessive ingestion of liquids that contain ethanol, for example, it can be beer;
• diabetes insipidus - such a disease is accompanied by the fact that the human body produces a large amount of light urine, up to several liters per day, which leads to a feeling of constant thirst;
• wrinkling of the kidney, which may be a primary or secondary pathological condition;
• acute or chronic course of pyelonephritis;
• chronic form of glomerulonephritis;
• the course of diabetes mellitus of both the first and second types;
• hyperparathyroidism - despite the fact that this pathology is caused by a disruption in the functioning of the endocrine system, it negatively affects the kidneys.

Loss of fluid through the respiratory tract occurs when a person has:

• rhinitis of hypertrophic variety;
• adenoiditis - most often causes severe thirst in children;
• night snoring - it is because of this factor that people wake up at night from dry mouth or feel thirsty in the morning.

The loss of water through the lungs is caused by such pathological conditions:

Increased sweating is the main source of why the human body is dehydrated. This condition can be both pathological and physiological. In the latter case, sweating is caused by intense physical activity and hot season.

As for pathological increased sweating, it can occur due to:

• thyrotoxicosis;
• severe menopause, namely against the background of frequently recurring tides;
• acromegaly;
• Hodgkin's lymphoma;
• irrational use of medicines;
• a wide range of endocrine dysfunction.

The mechanism of water loss through the intestines is based on any conditions that, in their clinical picture have frequent vomiting or stool disorder in the form of diarrhea. It is also worth considering that thirst can be caused by concealment of hemorrhage in the gastrointestinal tract. This is typical for such ailments:

• malignant or benign tumors intestines;
• gastritis of any etiology;
• peptic ulcer of the duodenum or stomach;
• the formation of external or internal hemorrhoids;
• anal fissures, etc.

In addition, the following diseases or pathological conditions can lead to constant thirst:

• hepatitis or cirrhosis of the liver;
• head injury;
• extensive burns;
• mental disorders, in particular schizophrenia;
• the course of any infectious process;
• dental ailments;
• decreased osmolality of blood plasma;
• neoplasms in the brain;
• alcohol intoxication;
• diseases of the blood system;
• damage to the hypothalamus - it is in it that the center of thirst is located;
• sharp surgical pathologies abdominal organs - this should include inflammation of the appendix, perforated ulcer, cholecystitis and intestinal obstruction.

Dry mouth and thirst may be triggered side effects such medicines:

• diuretics;
• antibacterial substances of the tetracycline series;
• preparations containing lithium;
• medications used in the treatment of mental disorders.

An important role in the development of the sensation of thirst is played by:

• the use of fatty, salted and spicy foods;
• addiction to such a bad habit as smoking;
• abuse of strong coffee and sweet carbonated drinks.

As for constant thirst during pregnancy, in such situations it is also considered a pathological manifestation, especially in cases of additional alarming symptoms. The only exception is the first trimester of childbearing. During pregnancy for early dates almost all women suffer from toxicosis, which is characterized by profuse vomiting.

Symptoms

Constant thirst is often the first clinical sign and is almost never the only symptom.

In general, the symptoms will consist of those manifestations that are characteristic of the pathological condition that has become the source of this symptom.

Nevertheless, the most common symptoms that complement the constant thirst are considered to be:

• dryness in the mouth;
• the allocation of a large amount of light urine;
• coating of the tongue with a coating, the shade of which can vary from yellowish-white to gray or black;
• weakness and general malaise;
• fluctuations in blood pressure and heart rate - the appearance of such a sign is especially dangerous in combination with thirst in the late stages of bearing a child;
• bad smell or taste in the mouth;
• bouts of nausea, which quite often end in vomiting;
• violation of the act of defecation;
• temperature rise;
• severe skin itching;
• shortness of breath and belching;
• headaches and dizziness;
• shade change skin, it may become pathologically red, pale or cyanotic;
• frequent urge to urinate;
• swelling of the lower extremities;
• pain syndrome with localization in the area of ​​the affected organ;
• decreased or complete lack of appetite;
• sleep disturbance.

Patients need to remember that these are just some of the symptoms, the manifestation of which may be accompanied by a constant or strong feeling of thirst.

Diagnostics

If a person is constantly tormented by thirst, then, first of all, it is necessary to go for a consultation with a therapist. The doctor will conduct primary diagnostic measures, which will be aimed at:

• collection of the life history of the patient;
• studying the patient's medical history;
• conducting a detailed physical examination, which must necessarily include an assessment of the condition of the skin, as well as measuring temperature, pulse and blood tone;
• careful questioning of the patient;
• general analysis of blood and urine;
• blood biochemistry;
• microscopic examination of feces;
• Ultrasound and radiography;
• CT and MRI.

After the preliminary cause of constant thirst is established, the therapist will most likely refer the patient for examination to such specialists:

If there is constant thirst during pregnancy, you will also need to consult an obstetrician-gynecologist.

Treatment

"Strong thirst" is observed in diseases:

Kidney abscess - quite rare disease, which is characterized by the formation of a limited area of ​​​​inflammation filled with purulent infiltrate. The pathological focus is separated from the healthy tissues of this organ by a granulation shaft. The disease is one of the diseases requiring emergency surgical intervention.

prostate adenoma (adenoma prostate) at its core, the term is somewhat outdated, and therefore used today in a slightly different form - in the form of benign prostatic hyperplasia. Prostate adenoma, the symptoms of which we will consider below, is more familiar in this definition. The disease is characterized by the appearance of a small nodule (possibly several nodules), which gradually increases over time. The peculiarity of this disease is that, unlike cancer of this area, prostate adenoma is a benign formation.

Alcohol intoxication is a complex of behavioral disorders, physiological and psychological reactions that usually begin to progress after drinking alcohol in large doses.

As a result, there is a synthesis and accumulation of a specific substance - amyloid. It is a protein-polysaccharide compound, which in its basic properties is similar to starch. Normally, this protein is not produced in the body, so its formation is abnormal for a person and entails a violation of kidney function.

Anuria is a condition in which urine does not enter the bladder, and, as a result, it does not stand out. In this condition, the amount of urine emitted per day is reduced to fifty milliliters. With this clinical symptom, not only the absence of fluid in the bladder is noted, but also the urge to empty.

Questions and suggestions:

Doctors are sounding the alarm because of the rapid increase in the incidence of diabetes. A group of foreign scientists decided to highlight the main pre-diabetic symptoms that allow you to catch dangerous disease at an early stage of development and take timely measures to heal.

According to doctors, one of the first characteristic signals of the onset of diabetes is increased drowsiness, lethargy after eating. A similar reaction of the body is evidence that it is too loaded with carbohydrates. This is especially harmful if a person is fond of food stuffed with so-called "fast" carbohydrates, supplied with sugar or white sugar. wheat flour. If after dinner you are overcome by an unbearable desire to sleep, you need to reduce the amount of foods with "fast" carbohydrates. Instead, eat foods with "slow", more complex carbohydrates - cereals, vegetables, fresh fruits. It is also helpful to do some physical activity after eating, such as just walking around for 15 minutes.

Another formidable symptom is carbohydrate craving, that is, a strong craving for foods with simple carbohydrates. If you constantly crave sweets and starchy foods, then your pancreas is not working properly: it produces a large amount of insulin, which is why blood sugar levels do not remain stably even, but fall. Sharply removing sugar from the diet in such a situation is dangerous, but there is a way out - instead of sweets with refined sugar, use nuts, carrots, bananas.
High blood pressure with overweight- a faithful companion of diabetes. The blood becomes more viscous, which makes it difficult to move around the body, and the cells do not receive enough the right amount carbohydrates. In this case, it is necessary to lower the level of cholesterol in the blood and start losing weight.
A "beer" belly, indicating a concentration of fat in the abdomen, exacerbates the tendency to diabetes. Belly fat increases blood pressure increases the risk of cardiovascular disease. A fat belly with an overall high level of cholesterol greatly increases a person's chances of developing diabetes.

A strong feeling of thirst may be completely normal after an intense physical activity, on a hot afternoon, and even after eating something salty or spicy. But thirst, which appears for no reason and which is almost impossible to quench, is a serious signal sent by the body. What diseases are evidenced by constant thirst, let's talk further.
Doctors call the syndrome of constant thirst polydipsia. This is a pathological phenomenon that indicates a clear lack of fluid in the body. Fluid loss can be associated both with the above phenomena, and after a violation of the body (vomiting, increased sweating, diarrhea).
Those diseases, which are evidenced by constant thirst, can be quite serious, so this alarming "call" should not be ignored. Most often, thirst is provoked by diseases of the liver or kidneys, infectious diseases, increased blood sugar levels, improper water exchange, and burns. In addition, doctors also add what diseases you should think about when you have a constant desire to drink. These are mental illnesses, nervous disorders, schizophrenia, obsessive and depressive states, a feeling of thirst often occurs after head injuries, possibly resulting in a concussion.

The natural feeling of thirst allows the body to function normally. This is a biological motivation, thanks to which the body receives the amount of fluid it needs, and also maintains an optimal water-salt ratio. When thirsty, as you know, a feeling of dryness appears in the mouth. This feeling may be false or true. With false thirst, simply rinse your mouth with water, after which this feeling passes. If this was not enough, and the body requires a large amount of water, it's time to think about what diseases such a condition can speak of.

To prevent the feeling of constant desire to drink, it is necessary to replenish the sufficient supply of fluid required by your specific body in a timely manner. A properly calculated fluid requirement will prevent fluid from being admitted. For example, for 1 kg of body weight of an adult, about 40 g of water is needed. This is a daily requirement. Given these indicators, you can calculate how much water you need per day, and whether there is any reason to worry about unreasonably occurring thirst. Misconception that a person needs to drink at least two liters a day. Everyone has an individual need, depending on their own body weight. It is from this indicator that one should proceed. True, an amendment should be made to what kind of lifestyle an ordinary adult leads. Constant excessive sweating and spending a lot of energy require drinking more water. But to reduce the need for fluid can sedentary image life.

In addition, it should be taken into account that constant thirst indicates nervous overload and stress. If work is associated with excitement and anxiety, then thirst is inevitable.
Separately, it is worth talking about the thirst that occurs in children. First of all, in adolescents, thirst can be provoked for the reason that they lead an active and mobile lifestyle. In children, such a phenomenon as constant thirst indicates some dangerous conditions of the body. For example, such a violation of the cardiovascular system as congestive heart failure indicates a weakness of the heart muscle, which is not able to pump enough blood and oxygen. As soon as the child experiences even the slightest tension, his heart failure worsens, as evidenced by constant thirst.
Parents need to keep in mind that the child's urination and fluid intake should be proportional. Otherwise, you should consult a doctor and check the condition of the kidneys. The kidneys are the body's natural filtration system, and if their work is disrupted, they can completely stop absorbing water and retain enough of it in the organ systems.

In any case, you should not immediately draw conclusions about the presence of any diseases in a child or in oneself if frequent thirst is manifested. Watch small children for some time. If you notice any abnormalities, consult a doctor.
The most popular causes of unreasonable feeling of strong thirst is diabetes mellitus. If, along with a strong desire to drink, an uncontrollable feeling of hunger appears, as well as frequent urination, it can be assumed that these are symptoms of diabetes. It can manifest itself in a similar way in children and adults.
Another disease is diabetes insipidus. In this disease, the sensitivity of the kidneys to the antidiuretic hormone is disturbed, or the amount of this hormone decreases sharply. With this disease, they can also make themselves felt frequent urination, a strong feeling of thirst, but the child loses his appetite.

An irresistible desire to drink should be satisfied only with pure water. If you drink tea, juices and carbonated drinks, you can cause even more harm to the body and exacerbate the disease. If the body sends you any signals, try to understand what diseases it is trying to communicate. If the pathology, which is evidenced by constant thirst, has not been confirmed by doctors, reconsider your daily diet. Try to reduce the amount of spicy foods, salty foods, and sweets you eat. Remember that thirst is caused by excessive smoking and dehydration after drinking alcohol and coffee. Before you see a doctor, make sure that your thirst is not provoked by taking any medications prescribed for you.
