Energy balance

Bariatric surgery results in greater weight loss and higher rates of type 2 diabetes remission compared to sleeve gastrectomy, and is associated with reduced nephropathy and major adverse cardiovascular events.

For individuals with severe obesity and type 2 diabetes who have not achieved remission with lifestyle changes or medications, bariatric surgery (particularly Roux-en-Y gastric bypass) can be a highly effective option. It offers greater weight loss and diabetes remission rates than other surgical options like sleeve gastrectomy, along with reduced heart and kidney risks, though it carries higher surgical risks.
