Whether blood glucose 8.2mmol/l needs to take hypoglycemic medication depends on whether the value is measured fasting, 2 hours after a meal, or randomly. If the fasting blood glucose 8.2mmol/l is generally need to take drugs, 2 hours after meals and random blood glucose 8.2mmol/l is temporarily do not need to take drugs. 1. Fasting blood glucose 8.2mmol/l: normal fasting blood glucose is 3.9~6.1mmol/l, if more than 7.1mmol/l, the possibility of diabetes can not be excluded, it is recommended to combine with clinical symptoms, as well as postprandial blood glucose, random blood glucose and so on to make a clear diagnosis, and comply with the doctor’s advice to see if you need to take hypoglycemic drugs. 2. 2-hour postprandial or random blood glucose 8.2mmol/l: the normal range of 2-hour postprandial blood glucose is less than 7.8mmol/l, if the blood glucose is 7.8~11.1mmol/l, consider hypoglycemia. And random blood glucose generally needs to be greater than 11.1mmol/l to have diagnostic significance. Therefore, these two cases do not need to take hypoglycemic drugs for the time being, and can improve the blood sugar situation by reducing the intake of high-calorie and high-sugar foods, strengthening exercise and controlling body weight. Whether blood glucose 8.2mmol/l need to take hypoglycemic drugs, it is recommended to go to the hospital to consult the endocrinologist for further diagnosis.
