Vasopressin - a hormone, one of the main functions of which performs a delay and restore the normal level of fluid in the body.Active development vasopressin promotes activation of the kidneys and therefore the excretion of excess sodium, providing thus reducing its level in the blood.Upon completion of synthesis and hormone production in the hypothalamus of the brain, he freely "flows" in pituitary nerve fibers, and then released into the blood.
hormone vasopressin - active stimulant homeostasis
Increase the production and secretion of vasopressin are usually observed in a significant reduction in the amount of fluid in the body, reducing blood volume and the level of its osmolarity.In such cases, the hormone acts as a stabilizer homeostatic and protective functions of the organism as a whole.
Among the conditions that can cause the active production of vasopressin, stands out:
- various bleeding;
- lowered blood pressure;
- consequences receiving diuretics;
- dehydration.
Often there are conditions that actively produces the hormone vasopressin is depending on the availability of objective reasons.Accelerated secretion of the hormone called inadequate.In turn, the emergence of such unhealthy trends may indicate a serious illness that needs skilled diagnosis.
hormone vasopressin - function
Vasopressin has a direct impact on the walls of blood vessels, resulting in narrowing them arises, which in turn leads to increased blood pressure.
Due to the production of the hormone in the organism, made possible the regulation of fluid reabsorption in the renal tubules.This feature helps to increase the concentration of the urine and delay its release.
disadvantage in the production of the hormone by the hypothalamus could lead to the development of endocrine diseases, such as diabetes, one of the main symptoms of which serves a significant increase in urine output.The result is severe dehydration.
role of vasopressin for the body
Vasopressin is a hormone in the blood flow is most noticeable impact on the regulation of water metabolism in the body.Increased concentration of hormone in the blood leads to a reduction in the amount of urine.
Effects of vasopressin on the body:
- increase in reabsorption of liquids;
- active removal of sodium from the blood;
- increase in volume and blood pressure in the vessels;
- activation process fluid saturation of body tissues.
Vasopressin, among other things, has an active influence on the state of the muscle fibers.Moreover, oxytocin and vasopressin - a hormone that combined beneficial impact on the intellectual component of human activity and contribute to the formation of neural connections of the brain aimed at controlling aggressive reactions to a sense of attachment to loved ones.Perhaps that is why its second name: vasopressin - a hormone loyalty.
What causes lack of vasopressin synthesis?
Reduced admission vasopressin into the blood is a major cause of oppression capture liquid in the channels of the renal system and as a consequence - the development of diabetes.People with insufficient production of the hormone can torment constant thirst, dryness of the mouth, drying of the mucous membranes.
In the absence of access to the fluid a person develops dehydration, which is accompanied by weight loss, reducing the pressure in the arteries and blood vessels, nervous system dysfunction.
determines the level of vasopressin in the blood with blood tests and urine tests.Often, however, these diagnostic methods are little information that requires further analysis.
Vasopressin - a hormone whose levels can be lowered due to a genetic predisposition.Often difficulties in the production of hormones are the result of the presence of tumors in the hypothalamus or pituitary.In this case, the elimination of the problem is possible by surgery or radiotherapy.
excess vasopressin levels
excessive production of the hormone is known as the syndrome of inappropriate antidiuretic hormone secretion, which is less common diseases.Manifestations of the syndrome in terms of decreased density plasma excretion of concentrated urine, raising the level of sodium.
people with high levels of vasopressin worried about rapid weight gain, nausea, headaches, weakness, loss of appetite.For severe cases of excess vasopressin levels are conditions that cause loss of consciousness, coma, complete inhibition of the vital functions of the body, which ultimately leads to death.
elimination of pathological syndrome inadequate production of vasopressin
currently at the root of therapy aimed at bringing back to normal hormone secretion, is the elimination of the underlying pathology that causes the diagnosis.The most effective method of normalizing hormone is considered to control fluid intake.
Often in the course of therapy to a patient prescribers whose components contribute to blocking the effect of vasopressin on the body.This is especially medications containing lithium carbonate.
Drug restoring normal levels of vasopressin
To normalize the level of generation and receipt hormone blockers used in blood concentration in kidney and pituitary gland, including professionals prefer primarily "phenytoin" and "demeclocycline" affecting the vasopressin.Hormone comes back to normal, and the patient is assigned to urea, which has a supportive effect on the body.
presence of significant progress in this area, as well as the development of modern diagnostic equipment along with innovative medication means contribute to the effective fight against syndromes of excess and shortage of the hormone in the body.
Vasopressin - a hormone whose effects on the body are now actively being studied around the world.Only the timely diagnosis, as well as compliance with the recommendations of experts allows us to hope for a favorable outcome in the development of syndromes associated with the violation of the level of vasopressin.
