High blood pressure is a common condition that affects the body’s arteries. It’s also called hypertension. If you have high blood pressure, the force of the blood pushing against the artery walls is consistently too high. The heart has to work harder to pump blood.

Untreated, high blood pressure increases the risk of heart attack, stroke and other serious health problems. It’s important to have your blood pressure checked at least every two years starting at age 18. Some people need more frequent checks.

Healthy lifestyle habits —such as not smoking, exercising and eating well — can help prevent and treat high blood pressure. Some people need medicine to treat high blood pressure.
