Two-hour postprandial blood glucose 7.3mmol/L is normal, whether for normal people or those with diabetes or gestational diabetes. Normal people with blood sugar <7.8mmol/L two hours after meal can be diagnosed with diabetes if the blood sugar >11.1mmol/L after meal. In pregnancy, two-hour postprandial blood sugar <8.5mmol/L. In case of diabetic patients, postprandial blood sugar control at 7.3mmol/L indicates that the patient's blood sugar control is up to standard. It is better for diabetic patients to control fasting blood sugar at 6.5-7.0mmol/L and two-hour postprandial blood sugar at 7.3-8.5mmol/L. Obese patients with two-hour postprandial blood sugar at 7.3mmol/L need to pay attention because obesity is a causative factor for the development of type 2 diabetes. Especially for the high-risk group with coronary atherosclerotic heart disease or hypertension or hyperuricemia over 40 years old, due to the appearance of chronic metabolic syndrome, although it is normal for the high-risk group to have blood glucose at 7.3mmol/L, it is still necessary to check fasting blood glucose and postprandial glycated hemoglobin regularly, about once every 3 months or half a year.
