Normally 2-hour postprandial blood glucose should be less than 7.8 mmol/L, so 2-hour postprandial blood glucose of 8.8 mmol/L is not normal and is high. Normally the normal range of fasting blood glucose is 3.9 to 6.1 mmol/liter, and 2-hour postprandial blood glucose is less than 7.8 mmol/liter. So a 2-hour post-dinner blood glucose of 8.8 mmol/L is not normal because it is above the normal range. For patients with early diabetes, diabetes health education, medical nutritional therapy, exercise therapy, condition monitoring, and medication are used to control their symptoms. For patients with abnormal blood glucose, it is recommended to consult a doctor in time to clarify the cause of the disease and treat it under the guidance of the doctor.
