Traditional medical treatment of diabetes is still the more popular modality used today; however, this method gradually loses stability as the patient ages and becomes sicker, and still has a relatively high complication rate. Today, more and more people are trying surgical gastric bypass surgery to treat diabetes. The advantage of gastric bypass surgery is that it is effective in stabilizing glucose lowering, and patients are usually able to discontinue the associated glucose-lowering medications even after the surgery and maintain this stability over time. Of course, the above is only the most ideal treatment effect, and it requires a certain amount of effort from both the doctor and the patient to achieve this effect. How can gastric bypass surgery achieve long-term remission? First, it is important to choose an experienced surgeon. For the same procedure, an experienced and skilled surgeon will be able to develop an exclusive surgical plan based on the patient’s specific situation, which will enhance the postoperative results. A complete post-operative health management system is also needed. Unlike other surgeries, gastric bypass surgery still requires a period of adaptation in terms of diet and life after surgery. Therefore, a good bariatric surgery center will assign a health manager to communicate with the patient over a long period of time to provide life guidance. Secondly, the patient needs to follow the advice given by the doctor and the health manager, and to adjust the diet for at least six months after the surgery, so that the body can better adapt to the gastrointestinal environment after the surgery, which is also an important condition to guarantee the post-operative results.
