What are the functions of vasopressin? Hormone vasopressin

Vasopressin - a hormone, one of the main functions of which is the delay and restoration of the normal level of fluid in the body. Active production of vasopressin promotes the activation of the kidneys and, accordingly, the removal of excess sodium from the body, thus ensuring a decrease in its level in the blood. After the synthesis and production of the hormone in the hypothalamus of the brain, it freely "flows" into the pituitary gland through nerve fibers, and then it is thrown into the blood.

Hormone vasopressin - an active stimulant of homeostasis

Increase in the production and secretion of vasopressin is usually observed with a significant decrease in the amount of fluid in the body, a decrease in the volume of blood and the level of its osmolarity. In such cases, the hormone acts as a stabilizer of homeostasis and protective functions of the body as a whole.

Among the conditions that can cause active production of vasopressin, it is worth highlighting:

• Various bleeding;
• Low blood pressure;
• The consequences of taking diuretic drugs;
• dehydration.

Often, there are conditions in which the hormone vasopressin is actively produced regardless of the presence of objective causes. Accelerated hormone secretion is called inadequate. In turn, the emergence of such an unhealthy trend may indicate the presence of serious diseases, which requires a qualified diagnosis.

Hormone vasopressin - functions

Vasopressin has a direct effect on the walls of the vessels, resulting in their narrowing, which, in turn, leads to an increase in the level of blood pressure.

Thanks to the production of the hormone in the body, it becomes possible to regulate the reabsorption of the fluid in the renal canal area. This function helps to increase the concentration of urine and delay its release.

A deficiency in the production of the hormone by the hypothalamus can lead to the development of endocrine diseases, for example, diabetes mellitus, one of the main symptoms of which is a significant increase in the volume of excreted urine. The result is a strong dehydration of the body.

The role of the hormone vasopressin for the body

Vasopressin is a hormone, the flow of which into the blood most significantly affects the regulation of water metabolism in the body. Increased concentration of the hormone in the blood leads to a decrease in the amount of excreted urine.

Effects of vasopressin on the body:

• Increase the level of the reverse absorption of liquids;
• Active removal of sodium from the blood;
• Increase in the volume and pressure of blood in the vessels;
• Activation of processes of saturation of body tissues with liquid.

Vasopressin, among other things, has an active effect on the state of muscle fibers. Moreover, oxytocin and vasopressin are hormones that, in combination, have a beneficial effect on the intellectual component of human activity and are involved in the formation of brain neural connections aimed at controlling aggressive reactions, forming feelings of attachment to close people. Perhaps, that is why his second name: vasopressin is a hormone of fidelity.

What is the lack of synthesis of vasopressin?

Reduction in the intake of vasopressin in the blood is the main cause of oppression of fluid uptake in the channels of the renal system and as a consequence - the development of diabetes mellitus. People with insufficient hormone production can be tormented by constant thirst, a feeling of dryness in the mouth, drying out of the mucous membranes.

In the absence of access to liquid, dehydration develops in a person, which is accompanied by weight loss, a decrease in pressure in the arteries and vessels, a violation of the functions of the nervous system.

Determine the level of vasopressin in the blood with the help of a blood and urine test. However, often such diagnostic methods are not very informative, which requires additional analyzes.

Vasopressin is a hormone, the level of which can be lowered due to genetic predisposition. Often, difficulties in the production of the hormone arise as a result of the presence of tumors in the hypothalamus or pituitary. In this case, the elimination of the problem is possible by surgical intervention or radiotherapy.

Excess of vasopressin in the blood

Excess hormone production is known as Parkhon syndrome, which is a common pathology. Manifestations of the syndrome are expressed in lowering the density of blood plasma, removing concentrated urine from the body, increasing the sodium level.

People with an increased level of vasopressin are concerned about rapid weight gain, nausea, headaches, general weakness, loss of appetite. Severe cases of excess vasopressin in the blood include conditions that cause loss of consciousness, to whom, complete suppression of vital body functions, which ultimately leads to death.

Elimination of the pathological syndrome of inadequate vasopressin production

At the present time, the root of therapy aimed at bringing the hormone secretion back to normal is the elimination of the underlying pathology that causes this diagnosis. The most effective method of normalizing hormone production is control over fluid intake.

Often in the course of therapy, patients are prescribed drugs whose components contribute to blocking the effect of vasopressin on the body. This is primarily a medical product containing lithium carbonate.

Medication restoration of normal level of vasopressin

To normalize the level of production and intake of the hormone, blockers of its concentration in the kidneys and pituitary gland are used in the blood, among which specialists prefer, first of all, "Phenytoin" and "Demectocycline", which affects vasopressin. The hormone returns to normal, and the patient is assigned urea, which has a supporting effect on the body.

The presence of significant success in this field, as well as the development of modern diagnostic equipment, along with innovative medications, contribute to an effective control of the deficiency syndrome and excess hormone in the body.

Vasopressin is a hormone, the effect of which on the body is being actively studied all over the world. Only timely diagnosis, as well as adherence to the recommendations of specialists, allows us to hope for a favorable outcome in the development of syndromes associated with a violation of the level of vasopressin.
