What is the normal value for postprandial blood glucose?

One hour after a meal, blood glucose should not exceed 10.0 mmol/L, and the normal range for blood glucose two hours after a meal should be less than 7.8 mmol/L.

Postprandial blood glucose, referring to the blood glucose level two hours after eating, is an important indicator for assessing diabetes and impaired glucose tolerance. According to the World Health Organization (WHO) standards, the normal range for blood glucose two hours after a meal should be less than 7.8 mmol/L. If the blood glucose level two hours after a meal falls between 7.8 and 11.0 mmol/L, it may indicate impaired glucose tolerance, which is a prediabetic condition. When the blood glucose level two hours after a meal is equal to or greater than 11.1 mmol/L, particularly in the presence of symptoms of diabetes, a diagnosis of diabetes can be made. Generally, blood glucose one hour after a meal should not exceed 10.0 mmol/L, and two hours after a meal it should decrease to below 7.8 mmol/L. These values are based on statistical data from healthy populations, and the criteria may vary for individuals with diabetes or abnormal blood glucose levels.
