Total cholesterol of 6.2mmol/L LDL of 3.91mmol/L is usually not too serious. Under normal circumstances, the normal range of total cholesterol is 2.9~6.0mmol/L, and the normal range of LDL is less than 3.12mmol/L. According to the analysis of the current data, the mildly high total cholesterol and LDL, which are not much different from the normal ranges, may be caused by the long-term intake of high-fat diets, and other physiological reasons, which are generally not too serious. Although total cholesterol above 6.0 mmol/L may also indicate hypercholesterolemia, atherosclerosis, coronary heart disease and other diseases, but simply elevated total cholesterol is not significant; High LDL may be due to irrational diet, too little exercise, some patients are due to obesity, mental stress. If the total cholesterol index is 6.2mmol/L and the LDL index is 3.91mmol/L, it is necessary to be tested regularly, and once it is found that the index is persistently high, it is necessary to consult a doctor in time to analyze the cause and then treat the cause.
