High blood pressure (also known as hypertension) is a common condition that can have serious health consequences, contributing to nearly 500,000 deaths per year in the United States. Nearly 1 out of 2 adults—around 108 million—have high blood pressure, and only 1 in 4 have their condition under control. Fortunately, high blood pressure is preventable and treatable.
