The Impact of Metabolic Bariatric Surgery on Inflammatory Bowel Disease Risk and Outcomes in Adults With Obesity: a Propensity-matched, Nationwide, Analysis

1

Metabolic bariatric surgery (MBS) is the most effective weight loss method for patients with severe obesity.
2

The study analyzed the incidence of newly diagnosed inflammatory bowel disease (IBD) in obese patients undergoing MBS.
3

Patients with severe obesity who underwent MBS were hypothesized to have a higher incidence of de novo IBD.
4

The study utilized a national claims database to ensure robust diagnostic criteria and reduce potential bias.
5

The secondary objective was to assess IBD severity, hypothesizing that MBS patients would experience less severe disease.
