Resolution of Comorbidities and Impact on Longevity Following Bariatric and Metabolic Surgery.

Bariatric surgery is the most effective and durable treatment of severe obesity. In addition to weight loss, these operations result in significant improvement or resolution of many obesity-related comorbid diseases. There are now numerous studies demonstrating that bariatric surgery decreases all-cause mortality long-term compared with cohorts of patients who did not undergo surgery. Decreases in cancer, diabetes, and cardiovascular-related mortality are major contributors to this overall effect on life expectancy after bariatric surgery.
