Postprandial blood glucose refers to the blood glucose two hours after meals, which generally reflects the insulin secretion and the body’s sensitivity to insulin, using the two-hour postprandial blood glucose measurement to understand the patient’s insulin secretion or sensitivity. The normal range of two-hour postprandial blood glucose is 4.4-7.8mmol/L. If the two-hour postprandial blood glucose is between 7.8-11.1mmol/L, it is hypoglycemia; if the postprandial blood glucose is greater than 11.1mmol/L, it can be diagnosed as type 2 diabetes. Be sure to pay attention to diet control and strengthen exercise.
