  • High blood pressure (HBP) is a serious condition that can lead to coronary heart disease, heart failure, stroke, kidney failure, and other health problems.
  • “Blood pressure” is the force of blood pushing against the walls of the arteries as the heart pumps out blood. When this pressure rises and stays high over time, it can damage the body in many ways.
  • Blood pressure numbers include systolic and diastolic pressures. Systolic blood pressure is the pressure when the heart beats while pumping blood. Diastolic blood pressure is the pressure when the heart is at rest between beats.
  • All blood pressure levels above 120/80 mmHg increase your risk for the health problems related to HBP. A blood pressure level of 140/90 mmHg or higher is considered HBP for most adults. If you have diabetes or chronic kidney disease, a blood pressure of 130/80 mmHg or higher is considered HBP.
  • Blood pressure tends to rise with age. Certain medical problems and medicines may cause blood pressure to rise. In some women, blood pressure can go up if they use birth control pills, become pregnant, or take hormone replacement therapy.
  • Children younger than 10 years who have HBP often have another condition that’s causing it (such as kidney disease). Treating the underlying condition may resolve HBP.
  • In the United States, about 72 million people have HBP. This is about 1 in 3 adults. Certain traits, conditions, or habits may raise your risk for HBP. These include older age, race/ethnicity, overweight or obesity, gender, unhealthy lifestyle habits, a family history of HBP, long-lasting stress, and having prehypertension (blood pressure levels between 120–139/80–89).
  • HBP itself usually has no symptoms. Rarely, headaches may occur. Some people only learn that they have HBP after it causes health problems, such as coronary heart disease, stroke, or kidney failure.
  • Your doctor will diagnose HBP using the results of a blood pressure test. This test is easy and painless. It may be done several times to make sure the results are correct.
  • Doctors measure blood pressure in children and teens the same way they do in adults. However, the ranges for normal blood pressure and HBP are different for youth than for adults. These ranges are based on the average blood pressure levels for a child or teen’s age, gender, and height.
  • HBP in adults and children is treated with lifestyle changes and medicines. Lifestyle changes include following a healthy eating plan, doing enough physical activity, maintaining a healthy weight, quitting smoking, and managing and coping with stress.
  • If you have normal blood pressure, you can take steps to prevent or delay HBP. Healthy lifestyle habits can help you maintain normal blood pressure.
  • If you have HBP, you can take steps to prevent the long-term problems it can cause. Adopt healthy lifestyle habits and follow the treatment plan your doctor prescribes. Children and teens can prevent HBP and its related problems in the same ways.

    How Can High Blood Pressure Be Prevented?

    If You Have Normal Blood Pressure

    If you don’t have high blood pressure (HBP), you can take steps to prevent it. Lifestyle measures can help you maintain normal blood pressure.

    • Follow a healthy eating plan. This includes limiting the amount of sodium (salt) and alcohol that you consume. An example of a healthy eating plan is the National Heart, Lung, and Blood Institute’s Dietary Approaches to Stop Hypertension (DASH).
    • Lose weight if you’re overweight or obese.
    • Do enough physical activity.
    • Quit smoking.
    • Manage your stress and learn to cope with stress

    Many people who take one or more of these steps are able to prevent or delay HBP. The more steps you take, the more likely you are to lower your blood pressure and avoid related health problems.

    If You Have High Blood Pressure

    If you have HBP, you can still take steps to prevent the long-term problems it can cause. Lifestyle measures (listed above) and medicines can help you live a longer, more active life.

    Follow the treatment plan your doctor prescribes to control your blood pressure. It can help you prevent or delay coronary heart disease, stroke, kidney disease, and other health problems.

    Children and Teens

    A healthy lifestyle also can help prevent HBP in children and teens. Key steps include having a child:

    • Follow a healthy eating plan that focuses on plenty of fruits, vegetables, and, for children older than 4 years, low-fat dairy products. The plan also should be low in saturated and trans fats and salt.
    • Be active for at least 1 to 2 hours per day. Limit screen time in front of the TV or the computer to 2 hours per day at most.
    • Maintain a healthy weight. If your child is overweight, ask his or her doctor about how your child can safely lose weight.

    Make these habits part of a family health plan to help your child adopt and maintain a healthy lifestyle.
