High blood pressure (hypertension) in children is blood pressure that's the same as or higher than 95 percent of children who are the same sex, age and height as your child. There isn't a simple target blood pressure reading that indicates high blood pressure in children, because what's considered normal blood pressure changes as children grow.

High blood pressure in children younger than 10 years old is usually caused by another medical condition. High blood pressure in children can also develop for the same reasons it does in adults — being overweight, eating a poor diet and not exercising.

Lifestyle changes, such as eating a heart-healthy diet and exercising more, can help reduce high blood pressure in children. But, for some children, medications may be necessary.
