The 2-hour postprandial blood glucose of 9.2mmol/L is high and abnormal for normal people; for diabetic patients, it is within the target range and is normal. 1. The normal value of 2-hour postprandial blood glucose for normal people is below 7.8mmol/L, so 2-hour postprandial blood glucose 9.2mmol/L is high and abnormal, and it is recommended to consult a professional physician for a clear diagnosis. 2. For patients who have been diagnosed with diabetes in the past, generally the 2-hour postprandial blood glucose needs to be controlled below 10mmol/L. Therefore, the 2-hour postprandial blood glucose of 9.2mmol/L has reached the control target, and the current treatment program can be continued. Once abnormal elevation of blood glucose level is detected, it is recommended to seek medical treatment in time to avoid delaying the condition and causing adverse consequences.
