Can children with familial hypercholesterolemia live normal lives?

Yes, children and adolescents with familial hypercholesterolemia (FH) can live normal lives with proper management of the condition. This typically requires adherence to lifestyle changes, such as a healthy diet and regular physical activity, and may include pharmacological treatment to lower high cholesterol levels.

Understanding Familial Hypercholesterolemia

Familial hypercholesterolemia is a genetic disorder that leads to very high cholesterol levels from an early age. Unlike high cholesterol caused solely by lifestyle factors, FH is caused by inherited genes that result in significantly elevated low-density lipoprotein (LDL) cholesterol, which increases the risk of developing coronary heart disease and other heart conditions early in life [1].

The Importance of Early Diagnosis and Treatment

Because there are no obvious symptoms of high cholesterol in children and adolescents, early diagnosis through blood tests is crucial. It is recommended to perform the first cholesterol screening for children between the ages of 9 and 11, and to repeat it every 5 years. Some children may need to start screening at the age of 2 if there is a family history of high cholesterol or premature heart disease [1]. Treatment aims to lower LDL cholesterol levels to reduce the buildup of fatty deposits in the arteries, which can narrow or block them, increasing the risk of heart disease [1].

Lifestyle Changes as a First Line of Defense

Lifestyle changes are considered the primary treatment for high cholesterol in children and adolescents. This includes:

• Regular physical activity: Children should ensure they engage in regular physical activity and limit time spent sitting in front of screens [1].
• Healthy diet: Adopting a diet that limits foods rich in saturated fat, sugar, and cholesterol, while focusing on fresh fruits, vegetables, and whole grains [1].
• Maintaining a healthy weight: If the child is overweight or obese, losing weight can help lower cholesterol levels [1].

It is important that all family members participate in these changes to make them easier for the child to adhere to, and to improve the health of the entire family [1].

When is Medication Necessary?

In some cases, lifestyle changes alone may not be sufficient to lower cholesterol to healthy levels, especially in cases of familial hypercholesterolemia. A doctor may consider prescribing cholesterol-lowering medication for children aged 10 years or older if their LDL cholesterol levels are above 190 mg/dL even after six months of diet and exercise changes, or if they are above 160 mg/dL and they are at high risk for heart disease [1]. Statins are often the preferred medication to lower cholesterol and reduce the risk of heart disease and stroke [2]. Pharmacological treatment usually requires lifelong continuity, but in some cases, significant lifestyle changes may allow for a reduction in dose or even discontinuation of the medication [2].

Living a Normal Life with Familial Hypercholesterolemia

With regular medical follow-up, commitment to lifestyle changes, and medication when needed, children and adolescents with familial hypercholesterolemia can live normal, active lives. The goal is to manage the condition effectively to reduce long-term health risks and ensure a good quality of life.
