The normal 2-hour postprandial glucose range is different for diabetics and non-diabetics. The normal value of 2-hour postprandial blood glucose for non-diabetic patients is below 7.8mmol/L. For patients who have been diagnosed with diabetes in the past, the normal 2-hour postprandial blood glucose needs to be controlled under 10mmol/L. In addition to 2-hour postprandial blood glucose, regular monitoring of fasting blood glucose and glycated hemoglobin in daily life will help to fully understand the patient’s blood glucose level. Once the blood glucose level is found to be abnormally high or low, it is recommended to consult a doctor in time and follow the doctor’s instructions to standardize the treatment, so as to avoid delaying the condition and causing serious consequences.
