Diabetes health education: This is the key to the success or failure of diabetes management. Every diabetic patient should receive diabetes education in order to recognize diabetes and master the purpose of self-management. 2. Medical Nutritional Therapy: Control the patient’s total calorie intake, increase energy intake appropriately for those with low body weight, and reduce intake as appropriate for those who are obese. Ensure the intake of carbohydrate, protein and fat. It is recommended to eat more food rich in dietary fiber, which can delay food absorption, increase satiety and improve metabolic disorders. It is recommended to eat small, frequent and regular meals. 3. Exercise therapy: For patients with type 2 diabetes, exercise can increase insulin sensitivity. The development of exercise plan follows the principle of individualization, gradual progress and long-term persistence. 4. Condition monitoring: Regular monitoring of blood glucose, including fasting blood glucose, postprandial blood glucose and glycosylated hemoglobin. 5. Medication: If the goal of controlling blood glucose cannot be achieved through diet and exercise, medication is recommended. Medications include oral medications and injectable preparations. Oral medications include glibenclamide, acarbose, metformin, etc. Injectable preparations include insulin as well as insulin analogs. If symptoms related to diabetes occur, relevant risk factors should be controlled, timely consultation should be made, and medication should be standardized under the guidance of the doctor.
