High blood pressure: Not just an adult problem When parents imagine something like high blood pressure, they typically envision adults in their 40s or 50s. But, in fact, hypertension is diagnosed more and more often in children under age 18. Even though childhood is considered to be a period with unlimited energy and immunity, unhealthy eating habits, a lack of physical activity, being overweight and obese, and even genetic factors may render them vulnerable (Image: Pexels)

Causes of high blood pressure in children The problem is that high blood pressure can progress quietly in children. Unlike a fever or cough, it doesn’t always come with easily identifiable symptoms, and so it can pass under the radar until it starts to compromise a child’s health in a more serious way. Unchecked, high blood pressure in kids can heighten the risk of heart disease, kidney trouble and stroke in adulthood.

The problem is that high blood pressure can progress quietly in children. Unlike a fever or cough, it doesn’t always come with easily identifiable symptoms. Since it is usually hidden, the child's health is compromised without parents realising the enormity of the problem. If left unchecked, high blood pressure in children can increase the risk of heart disease, kidney trouble and stroke in adulthood.
Early intervention is the key “Early intervention is everything,” says Dr. Kavita Raghavan, Pediatric Cardiologist, Sunrise Children’s Hospital, Bengaluru. Parents have a critical role in identifying symptoms as well as promoting healthy habits and seeking timely medical guidance.

Early intervention is the key
“Early intervention is everything,” says Dr Kavita Raghavan, Pediatric Cardiologist, Sunrise Children’s Hospital, Bengaluru. Parents, the expert suggests, have a critical role in identifying symptoms as well as promoting healthy habits and seeking timely medical guidance. The thought of a child having high blood pressure may be scary, but it can usually be managed when your child makes lifestyle changes, eats the right foods, and is actively monitored, to allow them to enjoy their childhood and keep playing.
Symptoms of high blood pressure High blood pressure in kids can cause headaches, nosebleeds, dizziness or vision problems. They may at times experience irritability, fatigue or problems paying attention in school. They can be subtle, but such signs should not go unnoticed. What to do: Make sure your child has regular checkups and see the pediatrician as soon as possible if your child has recurring symptoms.

Improve diet and lifestyle habits Obesity and unhealthy diet are major contributors for the development of hypertension in children. Diets high in processed food, sugar and salt also put additional strain on the heart and blood vessels. What parents should do: Instead, promote healthy, balanced meals full of fresh fruits, vegetables, lean proteins and whole grains – and cut back on junk food and sugary beverages.

What to Do: Encourage children to get at least 60 minutes of moderate to vigorous play, sports or exercise each day. Cycling or walking around with the family can make it fun.
