“Postprandial blood glucose” is generally measured clinically as 2-hour postprandial blood glucose. A 2-hour postprandial blood glucose of 6.2 mmol/L is normal for both normal people and diabetics. 1. The normal value of 2-hour postprandial blood glucose for normal people is below 7.8mmol/L, so 2-hour postprandial blood glucose of 6.2mmol/L is within the normal range, which is normal and there is no need to worry too much. 2. For patients who have been diagnosed with diabetes in the past, the 2-hour postprandial blood glucose needs to be controlled below 10mmol/L, so the 2-hour postprandial blood glucose of 6.2mmol/L has reached the control target, and you can continue with the current treatment program. If abnormal blood glucose levels are found, it is recommended to go to a regular hospital for a detailed examination, to clarify the condition under the guidance of the doctor, and to actively diagnose and treat the disease.
