What should the postprandial blood glucose level be to be considered normal?

The normal postprandial blood glucose range 1 hour after a meal is 6.7-9.4 mmol/L, and the blood glucose level 2 hours after a meal should be lower than 7.8 mmol/L.

In healthy individuals, the normal postprandial blood glucose range 1 hour after a meal is 6.7-9.4 mmol/L, and the blood glucose level 2 hours after a meal should be lower than 7.8 mmol/L, indicating the body can effectively regulate blood glucose to a stable level after eating through normal insulin secretion and regulation. If the blood glucose level 2 hours after a meal is between 7.8-11.1 mmol/L, it suggests impaired glucose tolerance, which is a prediabetic state, and measures should be taken to prevent progression to diabetes.

For patients with diabetes, postprandial blood glucose control targets 2 hours after a meal should be individualized. Generally, it is recommended to maintain levels below 10.0 mmol/L to reduce the risk of chronic complications. It should be noted that when measuring blood glucose 2 hours postprandially, timing should start from the first bite of food, and usual dietary quantity and composition should be maintained, avoiding intentional fasting or overeating to ensure the measurement accurately reflects true blood glucose levels.

In daily life, regular monitoring of postprandial blood glucose helps evaluate the effectiveness of diet, physical activity, and medication treatments, allowing timely adjustments to blood sugar control plans and maintenance of stable blood glucose levels.
