Blood pressure is a measure of how hard the blood pushes against the walls of the arteries as it moves through the body. It's normal for your child's blood pressure to go up and down throughout the day. But if it stays up, your child has high blood pressure. Another name for high blood pressure is hypertension.
What is normal and what is high blood pressure depends on your child's age, sex, and height. The numbers change as your child grows.
Blood pressure is described with two numbers. For example, a child's reading might be 96/57 or "96 over 57."
When blood pressure is a little high, it may increase the risk of health problems later in life.
If blood pressure is very high, it can cause serious and immediate damage to a child's body, especially the heart and brain. This type of high blood pressure is rare. With very high blood pressure, your child or teen may need more tests to find the cause.
Primary, or essential, high blood pressure is the most common type of high blood pressure. With this type, doctors can't tell exactly what is causing the high blood pressure. But several things make a child more likely to get it. One is having a family history of it. Another is being overweight.
Secondary high blood pressure is caused by another disease or medicine. Problems that can cause secondary high blood pressure may include:
Sometimes it can be caused by medicine a child is taking.
Children age 3 and older often have their blood pressure checked during routine doctor visits. If your child's blood pressure reads high, you may be asked to bring your child in again for another blood pressure check.
The doctor might have your child wear a portable device to measure blood pressure over 24 hours.
Your child may need more tests to check for illnesses that may be causing high blood pressure.
High blood pressure is treated in different ways, depending on how high it is. When blood pressure is just a little high, doctors often treat it with lifestyle changes, like eating healthy foods and being more active.
If the blood pressure is higher, and if lifestyle changes don't help lower it, the doctor may recommend medicine.
If another health problem is causing the high blood pressure (secondary high blood pressure), and the levels are very high, treating the other health problem usually lowers the blood pressure. Your child may also need medicine to lower blood pressure.
Your doctor may suggest lifestyle changes to help lower your child's blood pressure. Try these tips:
If your child has very high blood pressure, medicines may be needed. Your doctor can tell you how long your child may need to take medicine.
It can be hard to remember to help your child take pills when there are no symptoms. But blood pressure will go back up if your child doesn't take the medicine.
Make your child's pill schedule as simple as you can. Try to plan a time for your child to take medicine along with something else that happens at that same time every day. This can be something like eating a meal or getting ready for bed. If that is hard to do, you or your child can set a daily alarm as a reminder.
Medicines for high blood pressure can have side effects. Ask your doctor what side effects to look for and what to do if you see them.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
