Total cholesterol of 5.30mmol/L is not necessarily due to hyperlipidemia. The normal index of total cholesterol is less than 5.17mmol/L. If the current total cholesterol index is 5.30mmol/L, it can only suggest that the cholesterol is high, but not necessarily due to hyperlipidemia. Besides this disease, there are many other factors that can cause high total cholesterol, such as cholestatic jaundice, hypothyroidism, nephrotic syndrome and so on. Total cholesterol is only temporarily higher than the normal value, and not much different from the normal range index, may also be caused by physiological factors, such as obesity, long-term smoking, heavy drinking, mental stress, etc., may cause cholesterol higher than the normal value, so the total cholesterol of 5.30 mmol / L is not necessarily hyperlipidemia. If the total cholesterol is found to be higher than the normal value, you should consult the doctor in time and take the next step to analyze the cause and then treat the symptoms.
