The 2-hour postprandial blood glucose is 9.4mmol/L, which is higher than the normal standard, but does not reach the diagnostic standard of diabetes mellitus. Normally, the 2-hour postprandial blood glucose value should be <7.8mmol/L, and the glucose tolerance is reduced if it is between 7.8 and 11.1mmol/L. It is recommended that the patient should repeat the blood glucose test or further consult the doctor for glucose tolerance test to clarify the blood glucose situation, and at the same time, pay attention to reasonable diet and appropriate exercise. The latest diagnosis of diabetes mellitus is based on the typical symptoms of "three more and one less" (excessive drinking, excessive urination, excessive eating, and weight loss) plus intravenous plasma glucose ≥11.1mmol/L or fasting glucose ≥7.0mmol/L at any time of the day, or glucose ≥11.1mmol/L at 2 hours after glucose tolerance test (OGTT), which meets the three criteria. mmol/L, a diagnosis of diabetes is made when one of these three is met. Impaired glucose tolerance is a sign that the body's pancreatic secretion function is mildly decreased and cannot tolerate and regulate the rapid rise in blood glucose. At this stage, if you adjust your diet and increase exercise in time, you can return to normal. If no attention is paid to regulation, then it may develop and worsen into diabetes. If diagnosed with diabetes, it is recommended that under the guidance of a physician reasonable diet, appropriate exercise with medication if necessary, comprehensive management of blood glucose. When high blood glucose is found 2 hours after meal, it is recommended to seek medical advice for further examination and treatment.
