Postprandial blood glucose of 6.1 mmol/L is a normal level and is not a cause for undue concern. The normal range of fasting blood glucose is between 3.9 and 6.1 mmol per liter, and the two-hour postprandial blood glucose level is usually less than 7.8 mmol per liter, so the postprandial blood glucose of 6.1 mmol per liter is a normal level, and there is no need to worry too much. People at high risk of developing diabetes, such as those with obesity and a family history of diabetes, should also pay attention to preventing diabetes in their daily lives by eating a low-salt, low-fat diet, controlling their weight, adhering to exercise, and undergoing regular medical checkups. If blood glucose exceeds the normal range, it is recommended that diabetes-related examinations be conducted in a timely manner for early diagnosis and treatment.
