Postprandial blood glucose is generally measured in the clinic as 2 hours postprandial blood glucose, normal people’s 2 hours postprandial blood glucose <7.8mmol/L. Diabetic patients' 2 hours postprandial blood glucose should be controlled within 10mmol/L. If the normal 2-hour postprandial blood glucose is more than 7.8mmol/L, it may be caused by dietary factors, such as eating too many sweets, etc. It may also be caused by disease factors, such as infections, stress, etc. When you find that your blood glucose is high, you should consult a doctor in time, and be guided by a professional doctor for diagnosis and treatment. For patients who have been previously diagnosed with diabetes, if the 2-hour postprandial blood glucose exceeds the control target, suggesting that the blood glucose control is not good, you should consult a medical professional in time to adjust the treatment plan. Once an abnormal increase in blood glucose level is detected, it is recommended to go to the endocrinology department of a regular hospital for consultation.
