The 2-hour postprandial blood glucose of 14.5 mmol/L is elevated above the target range for both normal people and diabetics. 1. The normal value of 2-hour postprandial blood glucose for normal people is below 7.8mmol/L. Therefore, 2-hour postprandial blood glucose of 14.5mmol/L is obviously elevated, which may be caused by eating too many sweets, or it may be caused by diabetes mellitus, infections, and other disease factors, and it is recommended to consult with 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 should be controlled below 10mmol/L, so the 2-hour postprandial blood glucose of 14.5mmol/L has not yet reached the control target, and it is necessary to consult with the doctor to adjust the treatment program. When a patient has a 2-hour postprandial blood glucose of 14.5mmol/L, it is recommended to consult a doctor to avoid delaying the condition.
