Low-density lipoprotein (LDL) 3.87 is higher than the normal range and can be treated by improving lifestyle and taking oral lipid-lowering drugs. 1. Improve lifestyle: LDL is one of the indexes of blood lipid examination. Elevated LDL can cause blood viscosity, plaque formation, etc., and increase the risk of cardiovascular and cerebrovascular diseases. Normally, low salt, low fat and low sugar diet, eat more vegetables and fruits, reduce the intake of high cholesterol food, such as animal offal, fat meat, etc., strengthen the exercise and weight control. 2. Medication: If LDL control is not satisfactory through diet and exercise, oral medication is needed. Commonly used medications include statin lipid-lowering drugs, such as atorvastatin calcium tablets, resuvastatin calcium tablets, and so on. Because statin lipid-lowering drugs may cause liver function abnormalities, liver function needs to be rechecked regularly. Specific medication should be taken under the guidance of a doctor.
