As for the surgical treatment of diabetes, the results of the clinical validation of gastric bypass surgery decades ago were that it is effective in treating obesity type 2 diabetes. Therefore, there is no doubt about the efficacy of surgery for diabetes. However, since there is such an effective surgery, why is the number of people with diabetes in China still so high? This phenomenon needs to be analyzed from several aspects: the spread of diabetes surgery. Although this surgery is a product of the last century, has existed for decades, and has developed into one of the most popular methods of weight loss in developed countries and regions abroad. However, its development in China started relatively late, with only a journey of more than ten years so far, and it is true that there are still many diabetic patients who do not know that this method is available to treat diabetes. The number of people with diabetes. China has become the country with the largest obese population in the world, and the majority of type 2 diabetes patients in China are currently obese, a phenomenon that has only developed in the period after the reform and opening up, so in reality, the number of people having diabetes surgery is far from being able to exceed the number of new patients that have grown over the years. The perception of diabetic patients. As an ancient disease, the prevailing treatment for diabetes to date is still the traditional taking of medication to lower sugar, a method that cannot cure the disease at its root. However, many elderly patients are reluctant to try new things due to the traditional old-fashioned concept problem, and are resistant to surgical treatment, which will only lead to more and more serious disease in the end. Of course, the above listed are objective factors, and diabetes surgery itself also exists this certain limitations, this surgery can only be for obesity formation of type 2 diabetes patients, and the patient’s own insulin function and the age of the disease and other aspects of physical data also have strict requirements, which limits many patients who want to do surgery also can not do surgery.
