Fasting blood glucose 5mmol/l, 2 hours after meal blood glucose 8mmol/l, hemoglobin 6% is normal or not, need to be combined with the specific conditions to determine, for the normal population 2 hours after meal blood glucose is on the high side, for the pregnant population in the normal range. In the normal population, fasting blood glucose ranges from 3.9 to 6.1 mmol/l (less than 5.1 mmol/l in pregnancy), 2-hour postprandial blood glucose is less than 7.8 mmol/l (less than 8.5 mmol/l in pregnancy), and glycosylated hemoglobin is 4% to 6%. The normal population as a whole seems to be on the high side of the 2-hour postprandial blood glucose, but has not yet reached the diagnostic criteria for diabetes mellitus, and needs to undergo a glucose tolerance test to make a definitive diagnosis. Elevated blood glucose needs to be controlled by daily diet and exercise, and if it is still not well controlled, it needs to be treated with standardized medication under the guidance of clinicians.
