High Blood Pressure in Children
We usually think of high blood pressure, or hypertension, as a problem that affects adults. But in fact, this condition can be present at all ages, even in infancy. About five of every 100 children have higher than normal blood pressure, although less than one in 100 has medically significant hypertension.
The term blood pressure actually refers to two separate measurements: systolic blood pressure is the highest pressure reached in the arteries as the heart pumps blood out for circulation through the body; and diastolic blood pressure is the much lower pressure that occurs in the arteries when the heart relaxes to take blood in between beats. If either or both of these measurements is above the range found in healthy individuals of similar age and sex, it's called hypertension.
Hypertension is more common among individuals of color than whites. It also seems to be more prevalent in some parts of the world; for example, it's very rare among Alaskan Eskimos but affects as many as 40 of every 100 adults in northern Japan. In many cases hypertension seems to develop with age. As a result, your child may show no signs of high blood pressure as an infant but may develop the condition as she grows.
Effects of High Blood Pressure
In most instances of high blood pressure, no known cause can be identified. However, when hypertension becomes severe in children, it's usually a symptom of another serious problem, such as kidney disease or abnormalities of the heart, or the nervous or endocrine (gland) system.
Fortunately, high blood pressure alone rarely causes serious problems in children and can be controlled through dietary changes, medication or a combination of the two. However, if hypertension is allowed to continue or become worse over many years, the prolonged extra pressure can lead to heart failure. In addition, the stress on blood vessels in the brain can cause them to burst, producing a stroke. Also, long-term hypertension causes changes in blood vessel walls that may result in damage to the kidneys, eyes and other organs. For these reasons it's important to follow the pediatrician's advice carefully if your child is diagnosed as having high blood pressure.
Symptoms of High Blood Pressure
In most routine physical examinations, your child's blood pressure will be measured. This is how hypertension is usually discovered. Most often, this condition causes no noticeable discomfort, but any of the following may indicate high blood pressure:
High Blood Pressure Tests
If your child is found to have high blood pressure, your pediatrician will order tests to see if there is an underlying medical problem causing it. These tests include studies of the urine and blood. Sometimes special X-rays are used to examine the blood supply to the kidneys. If, as in most cases, no causative medical problem can be found, the diagnosis of essential hypertension will be made.
