As we all know, diabetes is a disease that is difficult to treat completely, so diabetic patients basically worry every day whether they will suddenly develop complications, a “time bomb” in the body that makes many patients suffer from long-term psychological torture. As a chronic disease, the complications of diabetes are mainly due to fluctuations in blood sugar or inflammation caused by poor blood sugar control. In general, the time of complications of diabetes is mainly related to the patient’s body conditioning and the degree of disease remission. As long as the patient can follow the doctor’s requirements and develop healthy habits in terms of diet and take medication on time, the complications can be controlled for a relatively long time without occurring. The above is a more understandable state of traditional internal medicine treatment for diabetes, but there is a problem that as people age, their body functions decline in all aspects, or their tolerance to medication increases, and generally the amount of medication needs to continue to increase in the late stages of the disease, and even then, the incidence of complications from diabetes is much higher than in the early stages. In order to avoid the pain and suffering of diabetic patients in the advanced stages of the disease, weight loss surgery is an option to treat diabetes. Surgical treatment differs from traditional medical treatment by taking medication, which can effectively repair the function of insulin and restore the body’s sugar metabolism, so that the diabetes will also be improved. Generally, after the surgery, patients can no longer rely on medication to stabilize their blood sugar and their body will remain at normal blood sugar level for a long time.
