High Cholesterol in Children

(Hypercholesterolemia in Children)


High cholesterol is a higher than normal level of cholesterol in the blood. It is more common in adults but can occur in children.

There are 2 types of cholesterol that may have the most significant effect on cardiovascular disease. One is high density lipoproteins (HDL) or good cholesterol. High levels of HDL have been linked to a lower risk of heart disease. The second type is called low density lipoproteins (LDL) or bad cholesterol. High levels of LDL cholesterol can lead to blockages in the blood vessels. This can lead to heart attacks and strokes.

Causes    TOP

High cholesterol may be caused by a combination of factors, such as:

  • Being prone to high cholesterol due to your genes
  • Being overweight or obese
  • A high-fat diet and low activity levels

Risk Factors    TOP

Risk factors include:

  • Obesity
  • Having a family history of high cholesterol or heart disease or stroke
  • Having high blood pressure
  • Smoking
  • Having certain conditions, such as diabetes, kidney disease, and underactive thyroid
  • Some medications, such as steroids, isotretinoin [acne medicine], beta-blockers, protease inhibitors, diuretics, and cyclosporin

Symptoms    TOP

High cholesterol does not usually cause any symptoms.

Diagnosis    TOP

Screening tests help doctors identify children who have high cholesterol. The screening recommendations are:

  • 2-8 years old— no screening needed unless there are risk factors
  • 9-11 years old—should be screened at least once
  • 12-17 years old—no screening needed unless there are risk factors
  • 17-21 years old—should be screened at least once

Screening is done by testing the lipid levels in the blood when your child is not fasting, for example:

  • Total cholesterol (the total amount of cholesterol in the blood)
  • HDL—good cholesterol
  • LDL —bad cholesterol
  • Triglycerides (a type of fat that can also help predict the risk of future heart disease)

Note: Normal cholesterol levels are different for children than for adults. The doctor will use different cut-off points for diagnosing high cholesterol in your child. If the values are high, they will be repeated when your child has been fasting.

In addition to the blood test, the doctor will:

  • Ask about your child’s symptoms.
  • Take your child’s medical history.
  • Do a physical exam.

Treatment    TOP

Lifestyle changes are a very important part of treatment.


Your doctor may recommend that you make changes to your child’s diet, such as:

The doctor may refer you and your child to a registered dietitian. Your child may also be referred to weight loss clinics or cardiologists if very high. In fact most pediatricians would not use statins without a cardiologist recommendation

The doctor may refer your child to a:

  • Registered dietitian
  • Weight loss center
  • Cardiologist (especially if statins may need to be prescribed)

Physical Activity

Other lifestyle changes include:

  • Encourage your child to participate in moderate or vigorous exercise every day. Examples include running, doing gymnastics, or playing soccer.
  • Limit the amount of time your child spends in front of a screen. This includes watching TV, playing video games, or using the computer. Aim for less than 2 hours in front of a screen per day.

Medicine    TOP

The doctor may recommend cholesterol-lowering medication, like statins, if lifestyle changes are not helping. Medication is most often recommended if cholesterol is very high or your child has many risk factors for heart disease. This is usually prescribed by a specialist.

Prevention    TOP

For most children, high cholesterol can be prevented with healthy lifestyle habits such as:

  • Eat a diet that is rich in fruits, vegetables, and whole grains.
  • If your child is overweight, follow a safe weight loss program. Use a program recommended by your doctor or dietitian.
  • Encourage your child to participate in physical activity on a regular basis.
  • Talk to your child about the dangers of smoking.
  • Be a good role model for your child. For example, eat healthy food and participate in physical activities as a family.
