Normal range of blood glucose two hours after a meal

　　The normal postprandial (after-meal) two-hour blood glucose range is generally ＜7.8 mmol/L.

　　For individuals with prediabetes, including those with impaired fasting glucose or impaired glucose tolerance, postprandial two-hour blood glucose levels are typically between 7.8 and 11.0 mmol/L. At this stage, the body's ability to regulate blood glucose has become mildly abnormal, but it has not yet reached the diagnostic criteria for diabetes. Intervention through dietary control, increased physical activity, and other measures is necessary to prevent progression to diabetes. diabetes

　　Blood glucose control targets for patients with diabetes should be individualized. For non-pregnant adult patients, it is generally recommended to maintain postprandial two-hour blood glucose between 7.8 and 10.0 mmol/L. For elderly patients or those with severe complications, the target can be appropriately relaxed to around 11.1 mmol/L to avoid the risk of hypoglycemia. Stricter control is required for gestational diabetes, with postprandial two-hour blood glucose recommended to be ≤8.5 mmol/L to ensure maternal and fetal health.

　　It should be noted that the measurement of postprandial two-hour blood glucose should start timing from the first bite of food, and normal eating should be maintained before testing. If multiple measurements exceed the normal range, timely medical consultation and further examinations are needed to confirm the diagnosis and develop an intervention plan.
