If patients have elevated total serum cholesterol, they can be treated with lifestyle interventions and oral medications, as follows: 1. Lifestyle interventions: If the elevation is not much, it can generally be controlled by lifestyle interventions and improvements, such as quitting smoking, quitting alcohol, exercising to lose weight, having a low-salt and low-fat diet, and eating more fresh fruits and vegetables. In terms of meat products, white meat is preferred, that is, chicken, duck, fish, etc., and less pork can help to lower the total cholesterol level. 2. Oral medication: If the total cholesterol level is relatively high, it is difficult to control it by diet alone, so it is recommended that oral statin lipid-lowering drugs are preferred, such as atorvastatin or resulvastatin. If the patient is sensitive to statins or has had adverse reactions in the past, he can also choose Chinese medications such as lipid capsules for treatment. If a patient has high total cholesterol and is indeed a patient with coronary artery disease but cannot take statins, ezetimibe, a cholesterol absorption inhibitor, can be applied to lower the total cholesterol level.
