Hypertension in Adolescents

Medically reviewed by Last updated on Oct 3, 2022.

What is hypertension?

Hypertension is high blood pressure (BP). BP is the force of the blood moving against the walls of the arteries. Hypertension causes your teen's heart to work much harder than normal. This can damage his or her heart. High BP in adolescence increases your teen's risk for hypertension and cardiovascular disease as an adult. A controlled BP helps protect your teen's organs, such as his or her heart, lungs, brain, and kidneys.

What causes or increases my teen's risk for hypertension?

The cause of your teen's hypertension may not be known. Any of the following can increase his or her risk:

  • Low birth weight
  • A family history of hypertension
  • Obesity or being overweight
  • Not enough physical activity
  • A medical condition, such as diabetes, kidney disease, heart disease, or sleep apnea
  • Certain medicines, such as steroids or birth control pills
  • Use of tobacco products, alcohol, or illegal drugs

What are the signs and symptoms of hypertension?

Your teen may have no signs or symptoms, or any of the following:

  • Chest pain or palpations (changes in his or her heartbeat)
  • Headache
  • Changes in vision
  • Dizziness

What are the stages of hypertension?

Your child's healthcare provider will give him or her a BP goal based on age, health, and risk for cardiovascular disease. When your teen is 13, his or her BP will start being recorded as one of the following stages:

  • Normal BP is 119/79 or lower . Your teen's healthcare provider may only check his or her BP each year if it stays at a normal level.
  • Elevated BP is 120/79 to 129/79 . This is sometimes called prehypertension. Your teen's provider may suggest lifestyle changes to help lower his or her BP to a normal level. He or she may then check it again in 3 to 6 months.
  • Stage 1 hypertension is 130/80 to 139/89 . Your teen's provider may recommend lifestyle changes, medication, and checks every 3 to 6 months until the BP is controlled.
  • Stage 2 hypertension is 140/90 or higher . Your teen's provider will recommend lifestyle changes and may have him or her take 2 kinds of hypertension medicines. Your teen will also need to have his or her BP checked monthly until it is controlled.
Blood Pressure Readings

How is hypertension in adolescents diagnosed?

Your teen's healthcare provider will check his or her BP at several visits. Your teen may also need to check his or her BP at home. The provider will examine your teen and ask about medicines he or she takes. The provider will also ask if your teen has a family history of high BP and about any health conditions he or she has. Your teen's weight, heart, lungs, and eyes will be checked. Your teen may need any of the following tests:

  • An ambulatory blood pressure monitor (ABPM) is a device that your teen will wear. ABPM measures BP while your teen does regular daily activities. It records BP every 15 to 30 minutes during the day. It also records BP every 15 minutes to 1 hour at night. The recorded pressures help your teen's healthcare provider know if he or she has hypertension not seen at appointments.
  • Blood tests may help healthcare providers find the cause of your teen's hypertension. Blood tests can also help find other health problems caused by hypertension.
  • Urine tests will be done to check your teen's kidney function. Kidney problems can increase the risk for hypertension.

How is hypertension in adolescents treated?

The cause of the high BP may need to be treated. If no cause is found, treatment usually starts with lifestyle changes. Your teen may also need medicine if lifestyle changes alone are not enough. Your teen's healthcare provider may recommend any of the following, based on your teen's needs:

Ways to Lower Your Blood Pressure
  • Weight loss helps lower BP and keep it in a normal range. Your teen's healthcare provider can tell you what weight is healthy for him or her. The provider can help create a weight loss plan, if needed. Even a small amount of weight loss can make a big difference for your teen's BP.
  • Activity helps lower BP and can help your teen maintain a healthy weight. Most teens need at least 60 minutes of physical activity each day.
  • A healthy meal plan may mean changes to the amount or kinds of food your teen eats. You and your teen will be given more information on the Dietary Approaches to Stop Hypertension (DASH) eating plan. The DASH eating plan encourages eating fruits, vegetables, and whole grains. You may also meet with a dietitian to create a meal plan to fit your teen's needs.

  • Sodium (salt) limits can help prevent fluid from building up in your teen's body. Fluid buildup can affect his or her BP. You and your teen may be taught how to check labels to find low-sodium or no-salt-added foods. Some use potassium salts for flavor. Too much potassium can also cause health problems. Healthcare providers will tell you how much sodium and potassium are safe to have in a day.

  • A regular sleep routine can prevent high BP from getting worse. Your teen should go to sleep and wake up at the same times each day. He or she should not use electronic devices or watch TV for at least 1 hour before bed.
