cholesterol in children

Overview

High cholesterol in children means there is too much of a fatty substance called cholesterol in their blood. Over time, this can build up in the blood vessels and raise the risk of heart problems later in life.

High cholesterol in children is becoming more common, mainly because of rising rates of obesity and unhealthy eating habits. The inherited form is much rarer.

It can affect children of any age, but it is more likely if the child has a family history of high cholesterol or early heart disease, is overweight, or has certain health conditions like diabetes.

Symptoms

Symptoms in children

• Most children with high cholesterol have no symptoms at all.
• In rare, severe cases (like familial hypercholesterolemia), a child may have yellowish patches on the skin called xanthomas, especially around the eyes, elbows, or knees.

Symptoms in older adults

• High cholesterol does not cause symptoms until it leads to narrowed or blocked arteries. Then symptoms may include chest pain, shortness of breath, or leg pain when walking.

Causes

Main causes

• Unhealthy diet high in saturated and trans fats (like fatty meats, fried foods, and processed snacks)
• Lack of physical activity
• Genetics – some children inherit a condition that causes high cholesterol no matter how healthy their lifestyle

Risk factors

• Family history of high cholesterol or early heart disease (before age 55 in father/grandfather, before 65 in mother/grandmother)
• Being overweight or obese
• Having diabetes, kidney disease, or an underactive thyroid

When to see a doctor

Book a routine appointment if:

• If your child has a family history of high cholesterol or early heart disease
• If your child is overweight and you are concerned about their diet or activity
• As part of routine health checks if recommended by your doctor

Diagnosis

A blood test called a lipid panel measures total cholesterol, LDL (bad) cholesterol, HDL (good) cholesterol, and triglycerides. Your doctor may recommend this test if your child has risk factors.

Tests that may be done

• Lipid panel (blood test) – usually done after fasting for 9–12 hours
• Repeat testing if the first result is high

What to expect at your appointment

The test is quick and involves a small blood draw. Your child may need to avoid eating or drinking anything except water for several hours beforehand. Your doctor will explain the results and what they mean.

Treatment

Treatment for high cholesterol in children usually starts with healthy lifestyle changes. If levels are very high or there is a strong family history, medication may be considered, but only under a doctor's care.

Self-care at home

• Eat a heart-healthy diet: more fruits, vegetables, whole grains, and lean proteins, and less saturated fat
• Get at least 60 minutes of moderate-to-vigorous physical activity every day
• Limit screen time to encourage more active play
• Replace sugary drinks with water or milk

Medical treatments

If lifestyle changes are not enough, a doctor may prescribe a type of medication called a statin. Statins help lower cholesterol. This is only used for children with very high cholesterol or familial hypercholesterolemia. The doctor will choose the dose and type based on your child's needs.

Living with this condition

Managing cholesterol means making small, lasting changes as a family. Focus on cooking healthy meals together, being active, and celebrating progress rather than aiming for perfection.

Lifestyle tips

• Make physical activity a family habit: walks, bike rides, or active games
• Reduce processed foods, especially those high in fat and sugar
• Read food labels and choose products with less saturated fat

Diet and exercise

Aim for a diet rich in fruits, vegetables, whole grains, and fish. Limit red meat, butter, and fried foods. Encourage at least one hour of physical activity daily. Small steps add up.

Mental health and emotional wellbeing

Children may feel worried or different if they have high cholesterol. Reassure them that you are making healthy changes as a family and that everyone benefits. Praise their efforts, not just their numbers.

Prevention

For most children, high cholesterol can be prevented with a healthy diet and regular physical activity. If there is a strong genetic cause, prevention may not be possible, but early treatment can control it.

Screening programmes

Screening (blood testing) for high cholesterol is not routine for all children. It is usually done only if there is a family history of high cholesterol or early heart disease, or if the child is overweight or has other risk factors.

Complications

If left untreated

• Atherosclerosis – hardening and narrowing of the arteries
• Increased risk of heart attack or stroke in adulthood
• For children with familial hypercholesterolemia, heart problems can develop even in childhood if untreated

Long-term outlook

With early detection and lifestyle changes, most children with high cholesterol can lower their levels and reduce future heart risks. For those with genetic forms, medications are very effective. The key is to start healthy habits early and stay consistent.
