Lipid abnormalities are increasingly being detected in children, largely due to the rising prevalence of obesity and diabetes as well as earlier screening practices. However, pediatric lipid disorders differ significantly from those seen in adults, and if left untreated, they can increase the risk of cardiovascular diseases such as heart attacks later in life.
At Children’s Hospital Los Angeles, children with abnormal lipid levels are evaluated through a dedicated pediatric lipid clinic that focuses on early diagnosis and appropriate management. According to Sabitha Sasidharan Pillai, MD, a pediatric endocrinologist at the hospital and a specialist in lipid disorders, understanding the unique characteristics of lipid abnormalities in children is critical for preventing long-term health complications.
Dr. Sasidharan Pillai notes that lipid cutoffs used for adults should not be applied to children. Cholesterol and triglyceride levels that may appear normal or borderline in adults can be abnormal in pediatric patients because lipid thresholds vary by age. If these abnormalities begin in childhood, cardiovascular risk can accumulate over time. She advises that children with persistently abnormal lipid values or unclear results based on pediatric-specific cutoffs should be referred for specialist evaluation.
Another key concern is extremely elevated lipid levels, which may indicate inherited disorders rather than lifestyle-related causes. LDL cholesterol levels approaching 400 mg/dL can suggest homozygous familial hypercholesterolemia, while triglyceride levels nearing or exceeding 1,000 mg/dL may point to familial hypertriglyceridemia. In such cases, early identification is essential because untreated genetic lipid disorders can lead to early-onset atherosclerotic cardiovascular disease.
Dr. Sasidharan Pillai also explains that LDL cholesterol levels can sometimes be misleading, particularly when triglyceride levels exceed 400 mg/dL. In these situations, standard LDL calculations may not provide an accurate picture of cardiovascular risk. Instead, non-HDL cholesterol, calculated by subtracting HDL from total cholesterol, can offer a more reliable indicator of atherogenic risk.
The specialist further cautions against the use of over-the-counter omega-3 supplements for managing lipid abnormalities in children. Since these supplements are not regulated by the U.S. Food and Drug Administration, they may not contain therapeutic doses and in some cases can even raise LDL cholesterol levels. When medication is required, prescription-grade omega-3 fatty acids should be administered under specialist supervision.
In addition to high lipid levels, abnormally low cholesterol should also not be ignored. Extremely low cholesterol may be associated with rare genetic conditions such as familial hypobetalipoproteinemia or abetalipoproteinemia. These disorders can lead to deficiencies in fat-soluble vitamins—including vitamins A, D, E, and K—as well as complications like fatty liver disease or cirrhosis.
Medical experts emphasize that timely diagnosis, appropriate testing, and specialist care are essential to ensure children with lipid disorders receive the right treatment and long-term health monitoring.
