Postprandial 2 hours blood glucose 9.8mmol/L is judged by different standards for different groups of people, elderly diabetic patients are generally regarded as normal, while for pregnant women and general population, they are abnormal and should be alerted. 1. Diabetic patients: If they are elderly diabetic patients with more underlying diseases, such as the original occurrence of coronary heart disease, myocardial infarction, arrhythmia, cerebral hemorrhage, cerebral thrombosis, etc., and There is physical activity disorder, this kind of patients with 2 hours postprandial blood sugar 9.8mmol/L can generally be regarded as normal, because this part of patients have less exercise, blood sugar is not easy to reach the standard, and the main principle is not to have hypoglycemia. However, for diabetic patients with lighter disease and relatively younger age, they also belong to the high state; 2. Pregnant women: If during pregnancy, the patient has 2 hours postprandial blood sugar 9.8mmol/L, consider having gestational diabetes. During pregnancy, the blood sugar of 2 hours after meal does not exceed 8.5mmol/L, the blood sugar value of 1 hour after meal does not exceed 10.0mmol/L, the fasting blood sugar value does not exceed 5.1mmol/L, a little over the above range, consider suffering from gestational diabetes; 3, the general population: the blood sugar of 2 hours after meal 9.8mmol/L for the general population belongs to abnormal state. Normal people’s blood sugar 2 hours after meal should be less than 7.8mmol/L. Blood sugar 9.8mmol/L 2 hours after meal suggests abnormal glucose tolerance. Patients who want to know accurately whether they have abnormal glucose tolerance can do a glucose tolerance test to check the body’s insulin secretion. In daily life, both patients with abnormal glucose tolerance and diabetic patients should pay great attention to whether the postprandial blood glucose meets the standard. At the same time, fasting blood sugar and glycosylated hemoglobin should be monitored. Diabetic patients generally require glycosylated hemoglobin to be controlled at about 6.3%, while the value of glycosylated hemoglobin for normal people should be 4%-6%.
