Diabetic patients with fasting blood glucose 12mmol/L and postprandial blood glucose 19mmol/L are higher than the control target, suggesting that the blood glucose control is not up to standard. They can be treated by diet control, appropriate exercise and use of hypoglycemic drugs as prescribed by the doctor. 1. Diet control: diabetic patients need to control the total calorie of food, rational distribution of nutrients, small meals, eat more fresh vegetables and low sugar fruits, such as spinach, apples and so on. 2. Moderate exercise: Regular exercise can increase insulin sensitivity, improve quality of life, help control blood sugar and reduce cardiovascular risk factors. Aerobic exercise such as brisk walking, jogging, cycling and swimming can be chosen. 3. Use of medication: Diabetic patients can choose oral hypoglycemic drugs such as metformin and acarbose or subcutaneous insulin injection for glycemic control as prescribed by doctors. It is recommended that diabetic patients find high blood glucose levels, under the guidance of professional physicians to avoid delays in treatment.
