High Blood Pressure

High blood pressure is sometimes called the "silent killer" because it usually has no noticeable warning signs or symptoms until other serious problems arise.

In 2009, better than 37% of Alabamians reported having high blood pressure. Blood pressure is the force of blood against your artery walls as it circulates through your body. Blood pressure normally rises and falls throughout the day, but can cause health problems if it stays high for a long time. Having high blood pressure raises your risk for heart disease and stroke, the first and third leading causes of death in Alabama.

Know your numbers: blood pressure is measured using two numbers. The first (systolic) number represents the pressure in your blood vessels when your heart beats. The second (diastolic) number represents the pressure in your vessels when your heart rest between beats. If the measurement reads 120 systolic and 80 diastolic, you would say "120 over 80" or write "120/80 mmHg."
