The treatment of diabetes is divided into three major parts: one is diet, two is exercise, three is the choice of hypoglycemic drugs. 1, diet. The most critical is the control of the amount of staple food, because staple food is rich in carbohydrates, the impact on post-prandial blood sugar is the largest, so the amount of staple food per day should be determined according to height, weight and activity, vegetables can eat more, meat, eggs, milk and other protein food can be added appropriately, high-fat things to eat as little as possible. 2, exercise. Diabetic patients can do appropriate low-intensity exercise after meals, which helps to lower blood sugar after meals as well as physical health. If strenuous exercise after meals, it is easy to produce hypoglycemia. 3, the choice of hypoglycemic drugs can be divided into two categories: oral hypoglycemic drugs and insulin. The specific choice of which type of medication is more suitable needs to be decided based on blood sugar levels, pancreatic islet function and complications. Diabetes maintenance is the need for outpatient follow-up. Patients with diabetes should regularly monitor fasting and two-hour blood glucose after three meals.
