High blood pressure, also called hypertension, is blood pressure that is higher than normal.

High blood pressure is consistently at or above 130/80 mm Hg.1

Your blood pressure changes throughout the day based on your activities. Having blood pressure consistently above normal may result in a diagnosis of high blood pressure.
