Nowadays, there are many people, including clinical prescribers, who do not know how to better treat type 2 diabetes, and most of them can only tell you helplessly that it is a lifelong disease and there is no way to cure it completely. Their understanding basically stays at the level of “glucose-lowering method” and prescribing glucose-lowering drugs, without any innovative treatment methods of their own. Today, medical research has found that weight loss metabolic surgery can alleviate and treat a portion of diabetes. The effect of surgery on the treatment of type 2 diabetes is very impressive, not only improving blood sugar and metabolic disorders, but also reducing the occurrence of diabetic complications in the long term. A large amount of clinical data proves that the complete remission rate (clinical cure rate) of weight loss metabolic surgery for type 2 diabetes is now more than 80% and the overall effectiveness is more than 95%, and it has become a reality for diabetic patients to get rid of internal medicine to keep their blood sugar stable. Gastric bypass surgery does not remove any organs from the body, does not damage the integrity of the gastrointestinal tract, and does not alter the inherent physiological state of the gastrointestinal tract, does not affect feeding and nutrient absorption, and causes minimal harm to the body. Therefore, there are no side effects associated with gastric bypass surgery. The procedure has been in development for more than 50 years, and in the United States, more than 300,000 people undergo the procedure each year; in China, where the procedure began in 2007, there are now more than 10,000 surgical cases each year, and the rate of growth continues at 30% per year. Diabetes topped the list. Its remarkable effect in treating diabetes and its complications has been recognized by the International Diabetes Federation (IDF), the European Association for the Study of Diabetes (EASD), the American Diabetes Association (ADA) and other international medical institutions specializing in diabetes, and has been clinically promoted and popularized in major hospitals in more than 120 countries and regions worldwide. It is recognized as one of the most effective treatments for diabetic patients to leave lifelong medication and complications behind, benefiting more than one million patients. After more than 10 years of development, the number of cases receiving bariatric surgery for obesity and type 2 diabetes has been increasing year by year, showing a good development trend. We also carry out strict checks on preoperative examinations and insist on not operating on patients who do not qualify for surgical treatment. However, in addition to the effect of different surgical centers, the post-operative follow-up guidance also differs. The mature medical team and professional technology is the primary condition in addition, and the limiting effect of surgery alone is far from enough. In order to guarantee the long-term results of post-operative patients and rebuild healthy living and eating habits, our hospital has established the first and largest health management department in China, which consists of more than 20 professionals such as health managers, nutritionists and psychological counselors, tailoring the post-operative recovery program for each patient based on the big data of more than 1,000 cases, providing long-term professional nutritional assessment and health management for obese and diabetic patients as well as individualized counseling education, nutritional survey evaluation and dietary guidance to ensure each patient’s surgical safety and long-term results.
