Metabolic and bariatric surgery significantly reduces insulin dependency in diabetes.

In a study of 287 patients with insulin-treated type 2 diabetes, metabolic and bariatric surgery (MBS) showed remarkable efficacy. At five years post-surgery, insulin dependence dropped from complete dependency to 36.2%, and the use of non-insulin antidiabetic drugs decreased from 79.4% to 26.1%. Additionally, type 2 diabetes remission rates were highest after biliopancreatic diversion with duodenal switch (73.7%), compared to roux-en-y gastric bypass (43.2%) and sleeve gastrectomy (23.3%).
