Whether or not the medication can be stopped when the blood lipids are normal needs to be determined by the specific condition. For patients with simple hyperlipidemia, if the blood lipids reach the desired level through exercise, diet, and medication, the medication can be discontinued, and treatment related to exercise and diet alone can be given, with regular observation. If the lipid level is maintained stable, medication can be discontinued. For patients with hyperlipidemia, if they have underlying cardiovascular diseases and atherosclerosis-related diseases, their target lipid values are relatively low. After the lipid level is reduced to a relatively normal range, it is still necessary to insist on the application of lipid medication to avoid the rebound of lipid and the progress of atherosclerosis. In addition, for patients with coronary artery disease, statin lipid-lowering drugs need to be taken for life, rather than stopping the drugs when the blood lipids are normal.
