Severe hyperlipidemia in children is usually caused by excessive intake of lipids or abnormal lipid metabolism and other diseases, such as nephrotic syndrome, which can be treated by adjusting the diet structure, improving the lifestyle and medication. 1. Excessive intake of lipids: If the intake of lipids exceeds the body’s metabolic capacity, it may lead to severe dyslipidemia. In this case, it is necessary to adjust the child’s dietary structure, reduce the intake of high-fat foods such as animal offal and fatty meat, increase the intake of fresh vegetables and fruits, and exercise. 2. Lipid metabolism disorder: some diseases can also cause severe lipemia in babies, for example, babies with nephrotic syndrome can have proteinuria, hypoproteinemia and hyperlipidemia. In this case, you can complete the kidney biopsy under the guidance of the doctor to determine the type, and follow the doctor’s instructions to be glucocorticoid (such as prednisone) and other drugs to actively carry out the treatment. Significant edema and severe hypertension should be short-term restriction of water and sodium intake. Once the child is found to be seriously high blood lipid, it is recommended to take the child to the doctor as soon as possible to improve the relevant examination and standardized treatment. If you need to use drugs should also be used under the guidance of a doctor, do not blindly use drugs.
