What is high-normal blood pressure?
High-normal blood pressure (also called prehypertension) is blood pressure that is higher than normal but not high enough to be high blood pressure. It is a warning that your blood pressure is going up.
Blood pressure is a measure of how hard your blood pushes against the walls of your arteries. Blood pressure that is too high (also called hypertension) harms your blood vessels. This raises your risk of heart attack, stroke, kidney failure, and other health problems. But you can take steps to get your blood pressure back to normal.
