Almost all the deaths, diseases, and disabilities caused by high blood pressure are preventable. Find out how to keep hypertension in check.
One of the most dangerous things about hypertension -- or high blood pressure -- is that you may not know you have it. In fact, nearly one-third of people who have high blood pressure don't know it. That’s because high blood pressure doesn’t have any symptoms unless it’s very severe. The best way to know if your blood pressure is high is through regular checkups. You can also monitor blood pressure at home. This is especially important if you have a close relative who has high blood pressure.
