So far, there is no medical means to effectively repair the function of the islets, so the main point of treatment for diabetes (referring to type 2 diabetes, the same below) is still to control blood sugar, whether it is the diet control, exercise, hypoglycemic drugs that we usually mention, or the gradually emerging metabolic surgery for weight loss, the purpose of which is to use various principles to control blood sugar within a certain range and prevent excessive blood sugar from causing other complications and adverse reactions. Therefore, for diabetic patients, the purpose of treatment has been achieved by controlling blood glucose well, which is not difficult for early stage patients. Generally speaking, early diabetic patients still have some insulin secretion function, so as long as they pay attention to diet control, strengthen exercise, and cooperate with hypoglycemic drugs, many of them can achieve good effect of sugar control, although it is a bit troublesome, but it seems that they can be treated without using surgery. Diabetes is mainly caused by the pancreatic islets being in a high load state for a long time causing islet failure, so after suffering from diabetes, the pancreatic islets will keep working overtime and the insulin secretion function will become weaker and weaker, so the diabetes condition will become more and more serious. In the long run, decompression of the pancreas is also one of the important treatment steps in treating diabetes, and bariatric surgery can have such an effect. Bariatric surgery can reduce insulin resistance, lower blood sugar directly, and if the disease is mild, the pancreas has enough capacity to regulate it. We can also help recovery through exercise and other means, which can have a good effect on long-term treatment.
