Although blood lipid levels that are too high are usually a problem among older adults, young people can have high lipid levels caused by genetic disorders. Young people who have high lipid levels may be at risk of having heart attacks or strokes late in life. However, it is difficult to predict which children and adolescents with high lipid levels may be at risk as adults. Some clinicians believe that treatment of high lipid levels in children and adolescents may reduce the risk of heart attacks or strokes later on in life. If high levels of lipids are found, treatment with drugs such as statins can lower lipid levels. Based on the lack of currently available studies of this problem, it is not known if lowering lipid levels in young people reduces their risk of heart attacks or strokes later in life.
