Fasting blood glucose 5.6mmol/L two hours after meal blood glucose 9.7mmol/L generally has not yet reached the diagnosis of diabetes mellitus. The normal range of fasting blood glucose is 3.9~6.1mmol/L, so fasting blood glucose 5.6mmol/L belongs to the normal range. The normal range of two-hour postprandial blood glucose should be less than 7.8mmol/L, so the two-hour postprandial blood glucose of 9.7mmol/L is on the high side, but it has not reached the diagnosis of diabetes mellitus, that is, the two-hour postprandial blood glucose is greater than or equal to 11.1mmol/L. If you have a fasting blood sugar of 5.6mmol/L and a two-hour postprandial blood sugar of 9.7mmol/L, you can go to the hospital and ask your doctor to make a judgment.
