Abstract

The global prevalence of obesity and diabetes continues to rise, with metabolic-bariatric surgery recognised as an effective intervention for obesity and type 2 diabetes, offering potential for type 2 diabetes remission and improved glycaemic control. This guideline, developed by the Joint British D...

For those with type 2 diabetes on insulin, doses should be reduced by 35%&#x2013;50% during LRD and adjusted post-operatively based on individual glycaemic control.
