Total cholesterol, which is a general term for cholesteryl esters and free cholesterol, can be used to determine lipid metabolism, the risk of atherosclerosis, and to monitor the use of lipid-lowering drugs. Serum total cholesterol level is affected by many factors such as age, gender, mental and dietary, etc. Generally, men are higher than women, and mental workers are higher than manual workers, so there is no standardized reference value, but the borderline level, or elevated or lowered is considered as the risk level. Changes in total cholesterol also have certain clinical significance, when the increase can be seen in alcohol consumption, hypothyroidism, atherosclerosis caused by cardiovascular and cerebrovascular diseases, and the decrease can be seen in anemia, hyperthyroidism, etc. Therefore, if you find that the total cholesterol is elevated, you should consult a doctor in time, and choose the appropriate treatment drugs under the guidance of a professional doctor.
