Abstract

Bariatric surgery is a well-accepted treatment option for sustained weight loss and improvement in comorbid conditions; however, it is unclear which procedure (laparoscopic Roux-en-Y gastric bypass [LRYGB] or sleeve gastrectomy [LSG]) has the greatest effect on anthropometric and body composition outcomes. It is important to ascertain which bariatric procedure is most effective at maximizing excess weight loss and determining what body compartment is most affected so that individualized nutrition and physical activity interventions can be implemented. This article is a review of the literature published from 2016 to 2021 that investigates the effect of LRYGB compared to LSG on anthropometric and body composition parameters. Although the results indicate that clinical outcomes are comparable for LRYGB and LSG, further long-term research are warranted.
