Diabetic patients two hours after dinner blood glucose 7.2mmol / L is generally normal, belong to the sugar control target. For diabetic patients, the goal of glycemic control is generally in the fasting blood glucose 4.4mmol/L ~ 7.0mmol/L, non-fasting blood glucose does not exceed 10.0mmol/L, so two hours after dinner blood glucose (non-fasting blood glucose) 7.2mmol/L belongs to the glycemic control standard. It is also necessary to set sugar control goals according to individual circumstances, and the blood glucose control goals of elderly diabetic patients should be appropriately relaxed to prevent hypoglycemic reactions. Diabetic patients should go to the hospital for timely examination and treatment under the guidance of the doctor, and monitor the fluctuation of blood glucose on a regular basis.
