Hypertension: physiology and pathophysiology

Hypertension, also known as high blood pressure, is a condition in which the force of the blood against the walls of the arteries is too high. This increased force can damage the arteries, heart, and other organs of the body. 

The cause of hypertension is usually unknown, but it can be caused by an underlying medical condition, such as kidney disease or hardening of the arteries. Treatment for hypertension typically involves lifestyle changes, such as eating a healthy diet and getting regular exercise. In some cases, medication may also be necessary to control blood pressure.
