Abstract

Purpose of Review

Currently, 15.4% of the population has severe obesity. For adults with severe obesity, bariatric surgery is the most effective and cost-effective treatment available for mortality reduction, weight loss, and comorbidity resolution. Although most surgical patients experience significant weight loss in the year following surgery, a subset of patients experience weight regain thereafter. Weight regain can result in recurrence of comorbidities and reduction in the long-term cost-effectiveness of surgery. Weight regain prompts providers to consider additional interventions.

Recent Findings

We summarize illustrative studies from the past 5 years on the effectiveness of bariatric surgery; the prevalence of weight regain following surgery; anatomic and behavioral factors contributing to weight regain; and behavioral, surgical, and pharmacological interventions to reduce weight regain.

Summary

We conclude with recommendations for increasing the evidence base regarding effective methods for maximizing long-term weight loss and associated health and economic outcomes.
