Due to the national emphasis on people’s livelihood, the work in health science has been implemented to all regions. For the classification of diabetes, I believe we have long been no stranger to it, in the broad category is mainly divided into type 1 diabetes and type 2 diabetes. In terms of related treatment many sugar lovers have different opinions, in addition to the more common taking hypoglycemic drugs and insulin injections. There is also the weight loss surgery that can treat diabetes, the emergence of surgery, so that the treatment of obesity type 2 diabetes to get a great turnaround. As we all know, traditional diabetes treatment methods are only based on stabilizing blood sugar, requiring long-term adherence to medication, and even a lifetime of attention to lifestyle and eating habits to avoid complications, which does not allow diabetes to be effectively cured. This is the “common problem” that exists in most type 2 diabetes. However, for obese patients with type 2 diabetes, traditional treatments are now a “thing of the past” and it is now largely possible to avoid lifelong medication or insulin injections. In addition, the reconstructed gastrointestinal tract maintains the balance of intestinal flora to a certain extent, allowing the body to improve its blood glucose control function, so that bariatric surgery can be used to treat type 2 diabetes while losing weight. Since the treatment mechanism of weight loss surgery can only treat this part of patients with obesity type 2 diabetes, relatively speaking this is considered a treatment advantage for this group, so it is a great blessing among misfortunes to have obesity type 2 diabetes.
