Metabolic bariatric surgery is the most effective therapy for severe obesity, providing greater weight loss and mortality reduction than pharmacotherapy.
For severe obesity, surgery offers the highest chance of significant, sustained weight loss and resolution of comorbidities. Discuss eligibility with a bariatric specialist.
GoodSupportsHIGH confidence
Metabolic bariatric surgery has substantial evidence to show it is the most effective therapy for the treatment of severe obesity... Compared to newer weight-loss drugs, surgery delivers about five times more weight loss [44].
