High Blood Pressure (hypertension) is a condition in which blood pressure in blood vessels ( arteries and veins ) is abnormally high. Blood pressure is the measure of force exerted by the blood on the walls of blood vessels.
The normal blood of a healthy adult is considered close to 120/80. Normal contraction and relaxation of Hearts creates rhythmic pulse of blood along and against the walls of blood vessels.These walls are flexible enough to dilate or contract and then keep the pressure constant.
However, due to a variety reasons, the heart pumps more forcefully to move some amount of blood through the narrowed blood vessels into the capillaries. this results in increased blood pressure or high blood pressure.
The high blood pressure is exerted for a long time can damage the arterioles of liver, kidney or brain and even the overworked heart. Thus hypertension presents and increased risk of death from congestive heart failure, kidney failure or stroke.
