The main thing to do to treat high blood sugar is to do three things: 1, diet control, many diabetic patients are reluctant to carry out effective diet control, because after the control diet may feel hunger is more obvious, diet control is the most basic of diabetes treatment, diet control is not good, blood sugar is difficult to control. 2, appropriate exercise, after meals must be appropriate activities, on the one hand, the health benefits, on the other hand, can also effectively reduce the level of blood sugar after meals. The most crucial thing is to take oral hypoglycemic drugs or insulin treatment, the specific choice of oral hypoglycemic drugs or insulin treatment is mainly based on the level of blood sugar, the patient’s body type and the level of pancreatic function, to develop a more effective treatment plan. There is no dependence on insulin therapy, and many patients have the misconception that they can use insulin therapy, and insulin can also be discontinued after blood sugar control, and then continue glucose-lowering drug therapy.
