High blood pressure, once linked to older adults, is now rising alarmingly in children. Driven largely by increasing childhood obesity, this silent but serious condition poses long-term heart risks.

For many years, high blood pressure was mostly a problem for adults. But today, more children are facing it at a younger age, mainly because childhood obesity is on the rise.

According to Dr Aparna Govil Bhasker, Bariatric and Laparoscopic Surgeon at Saifee Hospital, Mumbai, the rapid increase in childhood and adolescent obesity has led to a rise in obesity-related high blood pressure in younger age groups.

“With obesity now recognised as the strongest risk factor for high blood pressure in children and teens, the scope of the issue is expanding. Other contributing risk factors include male gender, family history of hypertension, high salt intake, gestational age or birth weight, sedentary lifestyle, and poor dietary habits,” adds Dr Bhasker.

The obesity link, Dr Bhasker says, is both consistent and strong. “Indian school-based studies report hypertension prevalence rates between 2.5 percent and 6.5 percent , with even more children falling into the pre-hypertensive category,” she say.

High blood pressure in children doesn't go away as they grow up. It often continues into adulthood and raises the risk of serious health problems like strokes and heart attacks. “High blood pressure in childhood inevitably leads to an increased risk of cardiovascular events in adulthood, making early detection and management critical,” says Dr Bhasker.

The way high blood pressure is defined in children has changed. Earlier, it was based on age, gender, and height. Now, for those over 13, many countries follow adult guidelines. As per the American Association of Pediatrics, biological changes like disruption of the Renin-Angiotensin-Aldosterone System (RAAS), increased sympathetic nervous activity, and kidney compression due to fat, are fuelling rising blood pressure in obese children.

Dr Bhasker suggest tips to help children beat the odds:

• Prioritise healthy weight: Tackle obesity first, it’s the strongest driver of childhood hypertension. Reduce salt and sugar: Cut down on processed snacks, sugary drinks, and salty foods.
• Promote daily activity: Aim for 30–60 minutes of physical movement each day.
• Encourage balanced eating: Include more fruits, vegetables, and appropriate portion sizes.
• Seek early screening: Regular blood pressure checks can catch early signs, even in asymptomatic kids.
• Consider specialist care: In severe cases, medical treatment or even bariatric surgery may be advised. Dr Bhasker notes that “up to 74 percent hypertension remission is seen post-surgery.”
