The accumulation of this fatty substance in the blood can stick to the artery walls, causing them to narrow or become blocked over time. This cumulative damage puts the child at a higher risk of developing coronary artery disease and other heart diseases later in life [\[1\]](). Because cholesterol is a substance necessary for normal body cell function, the danger lies in it exceeding safe levels—a condition that often does not show any tangible signs or symptoms, making periodic blood testing the only way to detect it [\[1\]](). ## Causes of high cholesterol in children Multiple factors contribute to elevated blood fat levels in children. The issue is not limited to aging but is influenced by a combination of environmental and genetic factors: - Unhealthy lifestyle: A diet rich in saturated fats and sugars, along with a lack of physical activity and sedentary time in front of screens, plays a central role in high cholesterol [\[1\]](). - Genetic factors: Family history is a decisive factor, especially if one or both parents suffer from high levels, or in cases of familial hypercholesterolemia [\[1\]](). - Chronic diseases: High cholesterol can be secondary to other health problems such as diabetes, kidney disease, or certain thyroid disorders [\[1\]](). For more details on the influencing factors, you can review our article on [High Cholesterol in Children and Adolescents: Genetic Causes, Lifestyle, and How to Manage It? (Arabic)](). ## Diagnosis and normal levels Diagnosis is made through a blood test that measures total cholesterol, triglycerides, LDL (bad cholesterol), and HDL (good cholesterol). It is globally recommended to perform the first screening between the ages of 9 and 11 and to repeat it every 5 years, while screening may begin at age two for children with a family history of high cholesterol or heart disease [\[1\]](). The following levels are considered healthy for those under 19 years old: - Total cholesterol: less than 170 mg/dL [\[1\]](). - LDL cholesterol: less than 110 mg/dL [\[1\]](). - Non-HDL cholesterol: less than 120 mg/dL [\[1\]](). - HDL cholesterol: greater than 45 mg/dL [\[1\]](). ## Management and treatment Lifestyle modification is the cornerstone of treatment; this includes increasing daily physical activity, improving the diet by increasing fruits and whole grains while reducing saturated fats, and losing weight if necessary [\[1\]](). When these changes are not enough, a doctor may consider using medications such as statins, especially if the child is over 10 years old and has LDL cholesterol levels exceeding 190 mg/dL after 6 months of lifestyle modification attempts, or if they exceed 160 mg/dL with additional heart disease risk factors [\[1\]](). It is important to note that some medications may require continuous use, but improving weight and lifestyle may allow for a reduction in the need for medication in certain cases later on [\[2\]](). You should always consult a specialist doctor to evaluate individual cases and adhere to the prescribed treatment plan. ## Medical references - [High Cholesterol in Children and Teens]() - [Cholesterol - drug treatment]() General health education; not a substitute for individualized clinical assessment.
