Causes hypertension hormonal origin associated with pathological processes in the pituitary gland, thyroid gland, adrenal glands.
Causes of secondary hypertension are in the field of disorders of the endocrine system. Environmental factors that affect the human body weather conditions, temperature, and changes in the internal organs in the process of evolution has created a unique system of adaptation. The stress and sense of danger cause the release into the blood of hormones that cause both low blood pressure and increased.
How are hormones and blood pressure?

The task of the circulatory system — time to ensure the access of oxygen or other authority. For this particular vessel is narrowed or expanded. This happens due to the receptors located in the cells of the tissues. The receptors react to certain hormones, running the desired process. The process regulates the pituitary gland and affects the adrenal glands that synthesize substances that affect the following parameters:
- the tone of the blood vessels, causing a sharp contraction,
- the work of the heart, causing his heart beating.
Causes hypertension hormonal origin
Causes hypertension hormonal origin associated with pathological processes in the pituitary gland, thyroid gland, adrenal glands. Diseases such as pheochromocytoma, Cushing’s syndrome, Cohn syndrome and hyperthyroidism lead to excess synthesis of hormones, is able to narrow the blood vessels, affect heart rate, heartbeat and to retain water in the body. Summary of secondary hypertension.
Hormones that increase pressure
Synthesized by the adrenal glands.
The adrenal glands consist of cortex and inner medulla. The latter produces an adrenaline release which speeds up the heart rate, constricts blood vessels and dilates the pupils. Tumor of the medulla of the adrenal glands, pheochromocytoma, triggers the release of adrenaline and noradrenaline. This leads to hypertensive crisis with headache and palpitations.

In the case when cortisol is elevated, formed of the disease — hyperadrenocorticism, Cushing’s syndrome and developing diabetes. Systolic blood pressure increased.
An excess of other adrenal hormone — aldosterone causes Cohn syndrome or hyperaldosteronism. The excess release of aldosterone is in the tumor (usually benign) or hyperplasia (tissue growth) of the adrenal gland. Aldosterone accumulate water and sodium in the walls of blood vessels and removes potassium. It affects the heart muscle and leads to increased blood pressure.
By enzymatic reaction of the androgens testosterone and Androstenedione are formed of steroid hormones — estrogens. Call them, respectively, estradiol and estrone, under the control of which is the reproductive system. They also affect the cardiovascular system, inhibit the development of atherosclerosis and is able to increase the amount of thyroxine T4 in the blood.
The body is not always on time, responds to the increase or decrease of estrogen. This explains why high blood pressure in adolescence, “tides” of blood to the head, redness and increased sweating in menopause. In men, excess estrogen increases the pressure and increases thrombus formation.
Synthesized by the thyroid gland
Hormones, raising HELL, include the thyroid hormones. The role of thyroid in human body to store iodine and synthesize the iodine-containing hormones which in turn regulate the metabolism — thyroxin T4 (tetraiodothyronine) and triiodothyronine T3.
The principle of operation of T3 and T4 following: in response to the change in the environment, when sharply colder or increased physical exertion, the person experiences emotional stress, the thyroid gland increases the level of hormones. This leads to a rush of blood to the surface of the body and increase body temperature to 37 degrees. Increased blood pressure. Heart pounding often. Blood vessels are in good shape, arteries are narrowed.
Hyperthyroidism, disease of the thyroid gland that causes excess hormone synthesis. All the positive aspects discussed above lead to negative consequences. Heart and blood vessels, are forced to work at elevated pressure. Thus, they wear out faster. There is irritability, man cannot control the psycho-emotional state. Accelerating the metabolism.
Hormones, lowering the pressure
If you experience large blood loss, increasing the ambient temperature in the case of lack of oxygen the level of T3 and T4 must be lowered. To survive in these conditions, reduces blood pressure and slow the heart. An underactive thyroid leads to hypothyroidism.
Insufficient synthesis of thyroxine and triiodothyronine leads to hypotension. As a consequence, disrupted to the brain due to insufficient amount of oxygen entering the blood. The heart breaks arrhythmia, bradycardia. Body temperature — in the range of 34.2—36.4 in. A dangerous complication is myxedema coma.
Necessary tests and treatment
If you suspect a hormone-dependent hypertension, the doctor will prescribe a series of blood tests, urine. Ultrasonic research of organs of the endocrine system is not showing the full extent of the presence of disease. The table lists the necessary tests to determine the disturbance in the endocrine system.
Because lack or excess of hormones acting on the AD — a result, it is necessary to determine the cause. Endocrinologist on the basis of their studies of blood, urine and CT scan appoints the treatment regimen. Conducted therapeutic action needs to normalize the hormones, and therefore reasons to reject pressure from that of 120/80 mm Hg. art should not be.published econet.ru.
