For the treatment of hyperlipidemia, first of all, it is essential to control your diet, avoiding foods that are too greasy. Foods that are typically braised or deep-fried should best be avoided. Secondly, when cooking, the amount of cooking oil should be controlled and it's recommended to opt for vegetable oils over animal fats, which are not advisable. Thirdly, if lipid levels remain high after dietary control, it is best to seek medical advice at a hospital and use lipid-lowering medication under the guidance of a doctor. Common lipid-lowering medications include statins and fibrates. The specific type of medication to be used should be based on the advice of the doctor. (Note: Specific medications should be taken under the supervision of a qualified medical professional.)
