Hypertension

Hypertension (HTN or HT), also known as high blood pressure (HBP), is a common disease in which blood flows through blood vessels, or arteries, at higher than normal pressures. It can lead to severe complications and increase the risks of heart disease, stroke, and death.

For most adults, normal blood pressure at rest is within the range of 100–130 millimeters mercury (mmHg) systolic and 60–80 mmHg diastolic. For most adults, if the resting blood pressure is persistently at or above 130/80 or 140/90 mmHg, high blood pressure is present.
