Antidiuretic Hormone in Kidney Failure

2013-04-25 15:57

Antidiuretic hormone and diuretic are most important hormones that adjust the water balance in body. Most of people with kidney failure make less or no urine, because antidiuretic hormone in kidney failure patients are usually more the general population. To correct this hormone normally has an important role in their whole treatment.

How does antidiuretic hormone work?

Antidiuretic hormone (ADH) is a hormone secreted by the posterior lobe of the pituitary gland, in the brain. ADH moves in the blood and reaches to its target organ, the kidney. The single most important effect of antidiuretic hormone is to conserve body water by reducing the loss of water in urine and prompting the reabsorption of water back into the circulation, while diuretic is an agent that can help increase the rate of urine formation. For people with kidney failure, the body usually secrete more antidiuretic hormone to make less urine so that less toxins and wastes can be removed from the body. In view of this, reducing this hormone is able to prompt the urine formation.

How to control the secretion of antidiuretic hormone in kidney failure?

Plasma crystal osmotic pressure , circulating blood volume and blood pressure are the main factors that adjust the secreting amount of ADH into the body.

The higher plasma crystal osmotic pressure, the more ADH is secreted. The amount of drinking water can affect it. Many people with kidney failure even don’t dare to drink water. In fact, this approach is wrong. Drinking correct amount of water is able to stimulate the body to make more urine.

Increasing blood flow is also useful to reduce antidiuretic hormone in kidney failure. Through extending the blood vessels, it can inhibit the activity of the posterior lobe of the pituitary gland so that less ADH is made. The other measure is to lower blood pressure.

According to the above analysis, some herbal medicines have an effect of extending blood vessels and lowering blood pressure, but the medicines which you are take should depend on your condition. Ask your doctor or us to make sure you are taking right treatment.
