In diabetic patients, the 2-hour postprandial control standard is generally below 10mmol/L, but in the case of pregnant diabetic patients, it is generally required to be controlled below 6.7mmol/L. In case of non-pregnant diabetic patients, 2 hours postprandial blood glucose, it is recommended to control below 10mmol/L. This is because if the 2-hour postprandial blood glucose is high for a long time, it may lead to diabetic nephropathy, diabetic retinopathy, and various types of cardiovascular diseases with a significantly higher likelihood. However, if the diabetic patient is a pregnant woman, it is recommended that the 2-hour postprandial blood glucose be controlled below 6.7 mmol/L. It is recommended that patients who find their postprandial blood glucose value is elevated, consult a doctor in time to improve the relevant examination, standardize the treatment, do control the diet, take medication on time, and regular review.
