After meal blood sugar 10.1mmol/L belongs to abnormal state, but does not reach the diagnosis standard of diabetes, the diagnosis standard of diabetes is two hours after meal blood sugar ≥ 11.1mmol/L. If the ordinary people blood sugar in 10.1mmol/L, currently belongs to the decreasing glucose tolerance, that is, the abnormal stage of glucose tolerance, this part of patients can not relax, should be controlled according to the diabetic diet The total calories eaten daily, including carbohydrates, fats, proteins, fruits, etc., need to be controlled according to the standard weight. Height minus 105 is the standard weight of the patient, to provide carbohydrates, fat and protein according to 30 calories per kilogram of body weight, of which carbohydrates account for about 50% of the total calories for the whole day, 20% for fat, 20%-25% for protein, and the rest for vegetables and fruits, and try to control the blood sugar within 8.5mmol/L two hours after meals, so that it is not easy to occur diabetes. If a diabetic patient’s postprandial blood sugar is 10.1mmol/L, it indicates that the patient’s blood sugar control is not up to standard and needs medical treatment, and it is better to control the postprandial blood sugar at about 8.5mmol/L. If a patient with gestational diabetes has a two-hour postprandial blood sugar of 10.1mmol/L, he or she should also seek medical treatment to avoid high blood sugar affecting the safety of the pregnant woman and the fetus. Elevated blood glucose must be given high attention because diabetes often coexists with metabolic diseases, including hypertension, coronary atherosclerotic heart disease, hyperlipidemia, hyperuricemia, obesity, etc. These chronic metabolic syndromes are all caused by hyperinsulinemia, so patients with diabetes are prone to metabolic diseases and should be given active treatment.
