Diabetes is an ancient disease that still has no cure from a thousand years ago, so the treatment of diabetes is quite complicated. Let’s first understand how diabetes develops: Excessive sugar intake or compromised insulin function can lead to the accumulation of excess sugar in the body and the gradual development of diabetes from elevated blood glucose. Of the two factors that can lead to diabetes, excessive sugar intake can be controlled by adjusting your diet, but the more complex treatment is when insulin function is affected. Insulin is an important factor in the body’s glucose metabolism, and once insulin does not function properly, even if the diet is controlled to the extreme, it cannot effectively treat diabetes. Therefore, for a long time, the only treatment for diabetes is through lifelong use of glucose-lowering drugs and later insulin injections. Although these methods can relieve the symptoms of the disease in the short term, in the long run, the disease will eventually suffer if it is not eradicated for a day. The purpose of weight loss surgery for diabetes is also to restore the function of insulin, mainly for patients with obesity type 2 diabetes. The surgery can effectively reduce food intake and absorption, thus reducing the energy intake and sugar metabolic load, a process that can successfully complete weight loss and help improve insulin resistance while reducing fat accumulation, thus restoring the body’s insulin function of breaking down sugar. The blood sugar level can be stabilized for a long time after the procedure, and the symptoms of diabetes can be effectively reversed, also avoiding lifelong medication as a form of treatment.
