In the early stages of the disease, the signs and symptoms are not obvious, which causes many people to miss the appropriate treatment stage. The general course of medical treatment for diabetics is to take glucose-lowering drugs to stabilize and control blood glucose levels, until later when ordinary medications are no longer sufficient to control them and insulin injections are needed. As time goes by, the amount of medication used will increase, but even so, there is no way to avoid the fact that complications are more likely to occur in advanced stages of diabetes. This is the main drawback of the current internal medicine treatment approach. In addition to the late stage of diabetes, which is the main stage of complications, complications can also occur in the first and middle stages. Although the chance of complications is relatively low under normal circumstances, the impact of severe blood glucose fluctuations is no less than that of advanced diabetes if it is a result of inattentive life intervention. Regardless of the stage of diabetes, the better way to avoid complications is to treat the diabetes rather than simply alleviate the condition, and the methods that can do this today include gastric bypass surgery. Gastric bypass surgery for diabetes has been proven for many years, but only for the type 2 diabetes group that is triggered by excessive obesity. In bariatric surgery centers with relatively mature technology and experience, patients are generally able to maintain a normal blood glucose range for a long time after surgery, while gradually returning to a normal life without relying on medication.
