Diabetes can not be cured, only through nutritional therapy, exercise therapy and medication for blood glucose control, it is recommended to actively treat under the guidance of a professional doctor. Diabetes mellitus is a group of metabolic diseases characterized by chronic hyperglycemia caused by multiple etiological factors, which is caused by defective insulin secretion or utilization. As far as the current medical diabetes etiology and pathogenesis are not completely clear, there is still a lack of etiologic treatment. Diabetes treatment methods are as follows: 1. Nutritional treatment: It is recommended that diabetic patients control the total intake of carbohydrates, pay attention to balanced nutrition, rationalize the intake of vegetables and fruits, and control the intake of sucrose and fructose. 2. Exercise therapy: Exercise therapy also plays an important role in the management of diabetes mellitus because it can increase insulin sensitivity through exercise, which helps to control blood glucose and body weight. 3. Medication: Patients can take Metformin and Repaglinide in their daily life. Insulin injection can also be chosen to control the symptoms of high blood sugar. For the control of diabetes mellitus, it is necessary to advocate reasonable diet in daily life, regular exercise, prevent obesity, and take oral hypoglycemic drugs or insulin injection for treatment every day under the advice of professional doctors.
