World Diabetes Day is celebrated every year on November 14. When it comes to diabetes treatment, the first thing that comes to mind is diet control, exercise, glucose-lowering drugs and insulin. For those who have been suffering from diabetes for a long time, a cure is still a distant thought. In 2011, the International Diabetes Federation issued a statement recognizing bariatric surgery as an appropriate treatment for obese patients with type 2 diabetes who have poor glycemic control. And many hospitals in China have also carried out diabetes surgery, which makes many sugar lovers full of expectation, and whether surgery for diabetes is suitable for all diabetes patients, and whether it can completely cure diabetes? Today, we will give you the answer. Weight loss and metabolic surgery is also known as “diabetes surgery”, which actually refers to surgery that can improve the metabolic function of the body. It has been proven that obese patients who have undergone weight loss surgery have experienced significant weight loss and good control of their blood sugar levels. The efficacy of diabetes surgery is based on 3 main principles: 1. Shrink the stomach, reduce energy intake and absorption, use the body’s excessive energy reserves, and maintain internal balance. 2.Reducing weight, most of the patients can lose about 30% of their body weight after surgery, and the insulin resistance caused by obesity will also be reduced, and blood sugar will gradually return to normal. 3.After gastrointestinal reconstruction, it can play the role of regulating the level of intestinal secretion of pro-insulin, so that the level of pancreatic secretion will be improved and blood sugar will be gradually normalized.
