The normal reference value of total serum cholesterol is 2.85-5.69 mmol/L. If the total cholesterol of a patient is 6.36 mmol/L, it is mildly elevated. Once cholesterol is increased, if lipid-lowering treatment is not carried out in time, it will easily cause the increase of blood lipid, which will lead to various kinds of cardiovascular diseases, with atherosclerosis being the most common, and then a series of symptoms and diseases, such as coronary heart disease caused by blood lipid in coronary arteries, stroke caused by intracranial arteries, fatty liver caused by internal organs, and nephropathy caused by renal arteries. The increase of total cholesterol is mostly related to bad habits, such as long-term overeating, especially eating a lot of fatty foods such as animal offal, drinking a lot of alcohol, and lack of exercise. To lower cholesterol index, patients need to improve their living habits, pay attention to low salt, low oil, light diet, avoid fatty meat, heart and brain organs and other foods, prohibit smoking and alcohol, as well as control weight and strengthen exercise. If the above treatment still cannot control the blood lipid within a desirable range, drug intervention is needed. Statin lipid-lowering drugs are preferred, and the representative drugs include lovastatin, atorvastatin, pravastatin, resupivastatin, etc. If you are allergic to statins, you can also use other lipid-lowering drugs, such as gemfibrozil, benzofibrate, blood lipid capsules, lipitor capsules, etc.
