High blood pressure or hypertension, is sometimes called the “silent killer” because most persons with high blood pressure don’t have any symptoms. Many people feel fine and as a result, don’t think they need to get their blood pressure checked. However, even if you feel normal, your health may be at risk.. All adults should have blood pressure checks at least once a year, especially if they have stressful occupations or a family history of hypertension.Talk to your doctor about your risk for high blood pressure.
