What is High Blood Pressure?
High blood pressure, also known as hypertension, is when the force of blood pushing against the artery wall is too high. High blood pressure is anything over 120/80. According to the National Heart, Lung, and Blood Institute, half of all American adults have high blood pressure and about one in three U.S. adults with high blood pressure don’t know it. High blood pressure doesn’t usually have symptoms until it causes serious health problems.
When blood pressure is too high for too long, the pressure can damage the walls of the arteries, causing small tears that when healed can contribute to plaque buildup. As plaque builds up over time, it causes the inside of the arteries to narrow which decreases blood flow and causes blood pressure to get even higher. These changes and increased pressure make the heart work harder and can lead to conditions like heart attacks and heart disease, strokes and cognitive decline, kidney disease, vision loss, and other health problems.
