Nearly one in three U.S. adults has high blood pressure. If that is not alarming enough, close to one-third of those who have high blood pressure don't know they have it. High blood pressure has no symptoms and if left untreated it can lead to heart attack, stroke, heart failure, kidney damage and other medical problems. In most cases, doctors do not know what causes high blood pressure, but research has shown that exercising, limiting salt and alcohol intake, losing weight and taking certain antihypertensive medications can control high blood pressure.
