Health Information For Parents
High blood pressure, or hypertension, is when the force of the blood pushing on the blood vessel walls is too high. When someone has high blood pressure:
After a while, high blood pressure can damage the heart, brain, kidneys, and eyes. Finding and treating high blood pressure early can help kids be healthy.
Blood pressure is the force against blood vessel walls as the heart pumps blood. When the heart squeezes and pushes blood into the vessels, blood pressure goes up. It comes down when the heart relaxes.
Blood pressure changes from minute to minute. It’s affected by activity and rest, body temperature, diet, emotions, posture, and medicines.
Most of the time, no specific cause is found. This is called essential hypertension.
When a cause is found, high blood pressure usually is from:
While high blood pressure is far more common in adults, kids and teens can have it too. High blood pressure can run in families.
Most of the time high blood pressure doesn’t cause symptoms. In rare cases, severe high blood pressure can cause headaches, blurry vision, dizziness, nosebleeds, a fluttering or racing heartbeat, and nausea.
If your child has high blood pressure and gets any of these symptoms, get medical care right away.
Health care providers measure blood pressure with a cuff that wraps around the upper arm or the leg in babies. When the cuff inflates, it squeezes a large artery, stopping the blood flow for a moment. Blood pressure is measured as air is slowly let out of the cuff, which lets blood flow through the artery again.
Blood pressure is measured in two numbers:
You hear blood pressure reported as the first number “over” the second number, like 120 over 80 or 120/80.
Diagnosing high blood pressure in kids can be tricky because there aren’t always symptoms and blood pressure can vary from day to day. Sometimes it can take several blood pressure checks to find out a child has high blood pressure.
Often, kids’ blood pressure will be higher when they are nervous. So, health care providers usually check blood pressure on a few different visits. Then, they use an average of those measurements.
For kids who are anxious and keep having high blood pressure at the doctor’s office, blood pressure may be measured somewhere else, like at home or by the school nurse. Sometimes doctors use a test called ambulatory blood pressure monitoring. The child wears a blood pressure cuff for a whole day and night. This can be better information than blood pressure tests in the doctor’s office because kids keep doing their usual activities, including sleep.
If high blood pressure is due to a condition like kidney disease or lung disease, treating it might be enough to get the blood pressure back to normal.
Doctors also might recommend lifestyle changes for kids with hypertension, such as:
Eating a healthy diet:
Getting regular exercise for 30–60 minutes at least 3 times a week. Kids with severe hypertension should not do any weightlifting or power-lifting, bodybuilding, or strength training until their blood pressure is under control and a doctor says it’s OK.
People with high blood pressure should not smoke, and their home and car should be smoke-free.
If diet and exercise changes do not improve the blood pressure, doctors may prescribe medicine.
Even though kids with high blood pressure generally feel fine, it’s important to follow the advice of the care team. A healthy diet and exercise, giving medicine if needed, and getting regular blood pressure checks can help healthy kids grow into healthy adults.
