A normal person’s two-hour postprandial blood glucose of 9mmol/l is abnormal, while a diabetic’s two-hour postprandial blood glucose of 9mmol/l is within the acceptable range. Normal two-hour postprandial blood glucose is less than 7.8mmol/l. If fasting blood glucose is less than 7.0mmol/l, but two-hour post-glucose load blood glucose is greater than or equal to 7.8mmol/l and less than 11.1mmol/l, it suggests impaired glucose tolerance. A glucose tolerance test is recommended. Abnormal glucose tolerance is a pre-diabetic state, which can be controlled by diet and more exercise to delay the onset of diabetes. Diabetic patients with two-hour postprandial blood glucose 9.0mmol/l, within the acceptable range. Diabetic patients two hours after meal blood glucose advocate control within 10mmol/l, fasting blood glucose control between 4.4-7mmol/l. If the blood sugar control is too low hypoglycemic symptoms can easily occur. Normal people found 2 hours after meal blood sugar 9mmol/l, it is recommended to seek medical attention. Diabetic patients with 2 hours postprandial blood glucose control at 9mmol/l, you can continue to maintain the original dose of hypoglycemic drugs.
