hypertension

Ellen Says: ypertension (HTN) or high blood pressure is a chronic medical condition in which the blood pressure in the arteries is elevated.

It is the opposite of hypotension. It is classified as either primary (essential) or secondary. About 90-95% of cases are termed "primary hypertension", which refers to high blood pressure for which no medical cause can be found.

The remaining 5-10% of cases (Secondary hypertension) are caused by other conditions that affect the kidneys, arteries, heart, or endocrine system.

Persistent hypertension is one of the risk factors for strokes, heart attacks, heart failure and arterial aneurysm, and is a leading cause of chronic kidney failure.

Moderate elevation of arterial blood pressure leads to shortened life expectancy. Both dietary and lifestyle changes as well as medicines can improve blood pressure control and decrease the risk of associated health complications.
