Whether or not a high blood lipid level of 0.8 mmol/L requires medication needs to be determined in conjunction with the primary disease. If there are no other comorbidities, no medication is required for the time being; if there are other comorbidities, medication is required. Lipid tests include the following four items: total cholesterol, triglycerides, HDL cholesterol and LDL cholesterol. 1. If the lipid level is higher than the normal value of 0.8mmol/L, and there are no other comorbidities, no medication can be used for the time being. However, if it still cannot be lowered after adjusting the diet, such as low cholesterol, low-salt, low-fat and light diet, as well as increasing the exercise, then medication is needed. 2. If the blood fat is high 0.8mmol/L, combined with high blood pressure, coronary heart disease and other diseases, it is necessary to treat the original disease on the basis of dietary control, strengthen the exercise, and under the guidance of professional physicians, take lipid-lowering drugs, such as beta, statin and other drugs: fenofibrate, atorvastatin, pravastatin, etc. for treatment. It is recommended to consult a doctor in time and standardize the treatment under the doctor’s guidance.
