What sugar lovers don’t know is that even though many of them are able to keep their blood sugar under strict control, complications can still come. This is because blood glucose is only one important aspect of diabetes control. If blood glucose is satisfactorily controlled, and if treatment measures such as weight control, lipid regulation, blood pressure reduction, smoking cessation and alcohol restriction, and aspirin use are not kept up, complications will often come as usual over time, so there is only one way to stop complications from coming, and that is to treat diabetes, not to relieve it. In fact, gastric bypass surgery is a reliable treatment for patients with obese type 2 diabetes, and it has been used abroad as the main treatment for obese type 2 diabetes. One comprehensive analysis of 22,094 patients showed that 84% of type 2 diabetes was completely reversed after surgery, and most patients discontinued oral medication or insulin therapy before discharge. Gastric bypass surgery is a recommended treatment by the International Diabetes Federation However, unfortunately, gastric bypass surgery in China is still in its early stages, and 95% of metabolic surgery in China is still sleeve gastric surgery. Many doctors who can perform the surgery lack cases, few have more than a thousand surgical cases, the surgery has not established a standard procedure, and there is insufficient experience in the care of postoperative complications. We believe that over time, Chinese doctors will be able to establish a big data model for gastric bypass surgery.
