In the tissues of the human body contains a variety of water and salt (or rather, ions).Major ions determining the salt composition of the blood plasma and tissue fluid, - a sodium and potassium, and anions of - chlorides.From the salt concentration in the internal environment of the body depends on its osmolality, provides a form of cells and their normal activities.The ratio of salt and water is called the water and electrolyte balance.When there is a violation of his thirst. Content
becomes clear that thirst can be caused by the following groups of reasons:
Often thirst is a lack of fluid intake volume.It depends on age, sex of
particularly necessary to monitor the amount of water drunk in the elderly, malnourished patients, children, and in the hot season.
water from the human body is displayed in the following ways:
Increased urine formation can be observed when taking diuretics.Many of them contribute to the removal of salts through the kidneys, which "pull" for a water.It has a diuretic effect, and many medicinal plants, as well as slimming.Therefore, you should review the medicines and herbal dietary supplements that takes people.
Increased urine formation and, consequently, causes thirst use of large volumes of fluid containing ethanol (e.g., beer).
If a man concerned about the constant thirst, accompanied by a large number of light-colored urine (up to several liters per day), the most likely cause of this condition is diabetes insipidus.This endocrine diseases associated with impaired water retention in the kidneys.It treats the disease endocrinologist.
primary and secondary contracted kidney, acute and chronic pyelonephritis, chronic glomerulonephritis - the most common kidney diseases that cause increased mochevyvedeniya and, as a consequence, the thirst.These diseases have a variety of clinical picture, so if you suspect they should consult a physician and to hand over a minimum set of tests to determine kidney function (general and biochemical blood tests, urinalysis, urine tests for Zimnitsky).
Separately, we must mention the so-called osmotic diuresis.When selecting from the body through renal salt or other osmotically active substances (e.g., glucose) by the laws of physics, there is a "stretch" them water.Increased excretion of fluids causes thirst.The main example of this condition is diabetes.Thirst in the beginning of the disease is accompanied by the release of large amounts of urine.Suspected diabetes will help itching.The first analysis of suspected diabetes should be the level of glucose in the blood and urine glucose tolerance test.
also cause thirst can become hyperparathyroidism.This endocrine disease associated with dysfunction of the parathyroid glands.When the disease occurs primarily leaching from the bone and calcium excretion in the urine.Calcium osmotically active and "pulls" for a water.Suspected hyperparathyroidism help weakness, fatigue, pain in the legs.A common early symptom is loss of teeth hyperparathyroidism.
constant nausea, frequent vomiting, weight loss is also characteristic of the disease.It is necessary to address to the endocrinologist for in-depth examination.
emergence thirst promotes constant mouth breathing.It may occur in hypertrophic rhinitis, adenoids in children, night snoring.Under these conditions best to contact the ENT doctor.
fluid loss through the respiratory tract is enhanced by rapid breathing (fever, anoxia, respiratory failure due to pulmonary disease, bronchitis, pneumonia).In case of complaints of shortness of breath is also necessary to address to the therapist for the study of the respiratory and cardiovascular systems (radiography and electrocardiogram included in the minimum set of studies).
We are talking about excessive sweating as a cause of constant thirst.Sweating may be a physiological time during the heat, intense physical work.
Pathological sweating (generalized hyperhidrosis) can be a symptom of hyperthyroidism, acromegaly, pathological menopause and other endocrine diseases, as well as Hodgkin's lymphoma.For the latter it is especially characteristic of sweating in the evening and at night.When excessive sweating is necessary to address to the endocrinologist.
should not forget about sweating as a side effect of certain medications (aspirin, insulin, etc.).Their method can also be accompanied by thirst.
Any conditions associated with vomiting or loose stools, causing thirst.
should also take into account the possibility of permanent hidden bleeding from the gastrointestinal tract (colon cancer, hemorrhoids and so on. D.).Blood loss can sometimes be accompanied by thirst.To confirm the loss of blood through the intestine is assigned primarily fecal occult blood.
Thirst - a natural consequence of the commitment to salty foods.The salt is absorbed from the stomach into the blood osmotic pressure increases, there is a protective reflex reaction of the organism - the thirst.
Increase revenue osmotically active substances is the cause of thirst in the abuse of coffee, soft drinks.
moderate thirst may be a manifestation of hyperkalemia - increasing the concentration of potassium in the blood.The main reason for this state - chronic renal failure.
Center thirst is in the hypothalamus.It can be affected by brain tumors, stroke and other focal lesions and brain injuries.In addition, disorders of the central regulation of thirst may occur in some psychiatric disorders.
At constant thirst is necessary:
