For diabetic patients, the glucose control goal is generally in the fasting blood glucose 4.4mmol / L ~ 7.0mmol / L, non-fasting blood glucose does not exceed 10.0mmol / L. Different conditions of diabetic patients, blood glucose has different control standards, if there is a risk of hypoglycemia, old age and other conditions, the target should be appropriately relaxed. Diabetic patients should set their glycemic control goals in a comprehensive manner according to their own conditions. For diabetic patients who are not elderly, newly diagnosed, with short disease duration, without complications and concomitant diseases, without risk of hypoglycemia, and with strong self-management ability, the glycemic control goal is generally at fasting glucose of 4.4mmol/L to 7.0mmol/L, and non-fasting glucose does not exceed 10.0mmol/L. If there is a risk of hypoglycemia, serious complications and concomitant diseases, poor self-management, old age, etc., the glycemic control target should be relaxed appropriately to reduce the risk of hypoglycemia. Patients with diabetes are advised to visit hospitals and ask their doctors to set appropriate glucose control targets.
