High Blood Pressure and Kidneys - An Overview

0 comments

The measure of the pressure inside your blood vessels is known as Blood pressure. When the pressure within the blood vessels is too high, the condition is called Hypertension. High blood pressure, if not given due attention can lead to serious health hazards. It makes working of the heart too hard, hardens the walls of arteries and can cause brain hemorrhage. It can also make the kidneys function poorly. Other dangerous situations caused by it include kidney failure, congestive heart failure and stroke.

In the present age, when many are suffering from kidney ailments as a result of hypertension, it is important to understand the relation between kidneys and high blood pressure.

The kidneys are sophisticated reprocessing machines, located near the middle of your back. The kidneys process about 200 quarts of blood to sift out about 2 quarts of waste products and extra water. The waste and extra water become urine, which flows to your bladder through tubes called ureters.

In addition to removing wastes, kidneys release three important hormones - Erythropoietin, which stimulates the bone marrow to make red blood cells; Rennin, which regulates blood pressure and Calcitriol, which maintains calcium for bones.

Hypertension makes your heart work harder and longer and can damage blood vessels throughout your body. As we discussed earlier, it is one of the leading causes of kidney failure. This condition is also known as end-stage renal disease (ESRD). It is indispensable for people with kidney failure to go for a kidney transplant or dialysis.
