You might think that hypertension, or high blood pressure, is a condition that only affects adults. However, according to the American Academy of Pediatrics (AAP), about 3.5% of children and adolescents have high blood pressure. If left untreated, the condition can lead to serious complications such as heart disease, kidney failure, stroke and vision loss.

What Is The Cause Of Diastolic Pressure Being High
“A blood pressure reading measures the force of blood on the artery walls. This is the pressure your heart needs to pump blood to the rest of your body,” explains Alan Singh, MD, a pediatric cardiologist at Children’s Heart. Specialists, Children’s Health – Care Network Partner. “If blood pressure is higher, the heart has to work harder. Over time, this high blood pressure can damage different organ systems in the body.”
Diastolic Heart Failure
However, regular screening helps detect high blood pressure in children. Learn more about what is considered high blood pressure in a child and ways to help keep a child healthy.
A child’s blood pressure should be checked once a year at an annual exam starting at age 3. Your child should sit comfortably in the chair with their feet up and their arms around their heart. Your child’s doctor or nurse will use a stethoscope and an arm cuff to check their blood pressure.
If a child has poor health, such as obesity or kidney disease, their blood pressure will be checked at each doctor’s visit. If a child has high blood pressure during a well-child visit, they will also have their blood pressure checked more often.
Your child’s pediatrician will monitor blood pressure trends over time in addition to an initial examination to make an accurate diagnosis of hypertension.
Systolic Vs. Diastolic Blood Pressure
There is no single number or blood pressure that is considered normal for all children. A healthy blood pressure for a child depends on their age, height and gender.
For children under 13, your pediatrician will use a percentile chart to compare your child’s blood pressure with peers of the same age, height, and gender. This allows for a more accurate indication if a young child has high blood pressure. A child is considered to have high blood pressure if it exceeds the 90th percentile, and hypertension if it exceeds the 95th percentile.
Normal blood pressure for teens over age 13 is the same as for adults:
If your child’s pediatrician notices a trend toward high blood pressure readings, they will monitor your child’s blood pressure closely or refer you to a specialist to address health issues. They may have your child wear a 24-hour, powered blood pressure monitoring device (called an ambulatory blood pressure monitor or ABPM). It can be worn during your child’s routine, taking measurements every 20-30 minutes during the day and 30-60 minutes at night.
Can Your Blood Pressure Be Too Low?
This monitor can give your pediatrician a complete picture of your child’s blood pressure throughout the day and night, helping them decide if the child needs further tests or treatment.
Hypertension is often a silent condition. Usually, there are no obvious symptoms to tell parents that their child has high blood pressure. it is often diagnosed when a doctor finds it during an exam. This is why regular blood pressure checks are so important.
Some children with high blood pressure may experience frequent headaches, vision changes, or dizziness. If your child complains of these symptoms, contact the pediatrician.
A child’s blood pressure can be high for many reasons, including stress, illness, recent physical activity, a true hypertension problem, or a medical condition.
Blood Pressure And Your Brain
When high blood pressure occurs in a young child (under age 6), the cause is often an underlying medical condition, such as kidney disease. This is called secondary hypertension.
When high blood pressure has no underlying medical cause, it is called primary hypertension. Primary hypertension is common in older children and adolescents and is usually associated with obesity or a family history of hypertension.
“The number of children and adolescents who are overweight or obese is increasing, and this is a major cause of high blood pressure in children,” says Smita Vidhi, a pediatric nephrologist and assistant professor of child health at Southwestern. “Also, children eat a lot of processed foods that are high in salt. A high-salt diet is a major contributor to high blood pressure.”
If your child is diagnosed with hypertension, your pediatrician may recommend certain lifestyle changes to lower blood pressure, such as a healthy diet, regular exercise, or weight loss.
What Is Low Diastolic Blood Pressure?
If needed, your child’s doctor can prescribe medication to control your blood pressure. These drugs are taken in doses appropriate for age and weight, just like adults. Your child’s doctor can choose the best medication for your child based on your health profile and risk factors.
You can help your child prevent high blood pressure and complications. Talk about the importance of a healthy lifestyle and set a good example – make healthy food choices and exercise as a family.
“Taking steps to stay healthy as a family is key to preventing hypertension in children,” says Dr. Widi. “Try to spend some time each day doing something fun with your kids, like biking, dancing, swimming, or even going to a nearby park.”
Regardless of the cause of a child’s high blood pressure, a child health professional can provide multidisciplinary care. Learn more about hypertension and how we can help.
Diastolic Blood Pressure Changes During Exercise Positively Correlate With Serum Cholesterol And Insulin Resistance
Blood pressure has two numbers. Systolic pressure, the force exerted on the blood vessels when the heart beats, is the top number. Diastolic pressure, the force exerted when the heart is at rest, is more than one at the bottom. Systolic blood pressure gets the attention of doctors and patients alike, says cardiologist Jason Guchard, MD.
“Doctors are busy with people, and they often focus on one number,” Guichard said. “Systolic blood pressure is the main focus, and diastolic pressure is completely ignored.” It’s a mistake, he says. “Most of your arteries supply your organs during systole. But your coronary arteries are different; they bypass the aortic valve, so they only get blood when the aortic valve is closed – and that happens in diastole. “
Diastolic pressure has received more attention recently, but in part because of an influential paper in Hypertension, published in 2011 by Guichard and Ali Ahmed, M.D., then MD, professor of medicine in the Department of Gerontology, Geriatrics, and Palliative Care. Associate Chief of Health and Aging at the Veterans Affairs Medical Center in Washington (Ahmed remains a faculty member.)
Reading A Home Blood Pressure Monitor
This paper coined a new term, “isolated diastolic hypotension,” for low diastolic blood pressure (less than 60 mm Hg) and normal systolic blood pressure (greater than 100 mm Hg). The researchers found that older adults with these conditions have an increased risk of developing heart failure.
“High blood pressure is a problem, but low blood pressure is also a problem,” Guichard said. This implementation helped lead to a decision by panel members appointed to the Eighth Joint National Committee (JNC 8) in 2014 to relax blood pressure targets for people over 60 years of age. [Read Guichard’s “ideal blood pressure” and new guidelines in this blog post.]
“Years ago and more recently, doctors treated their blood pressure so aggressively that many patients couldn’t get up without feeling dizzy,” Guichard said. “We want to let patients know that you don’t have to throw these numbers away, you can’t play with your grandkids, you can’t play golf, or you can’t just walk around the block. Your blood pressure is too low. I think it’s important to increase awareness in this area, especially for older people.”
Jason Guichard Ahmed and Guichard continue to study the mechanisms of low diastolic blood pressure in detail. According to Guichard, several new papers are expected. In the meantime, he sat down with Meeks to explain the dangers associated with low blood pressure.
