Changes in Resting Energy Expenditure After Sleeve Gastrectomy: a Review of the Literature.

Obesity is a rising medical condition; metabolic and bariatric surgery, mainly sleeve gastrectomy, offers a successful weight loss option which is maintainable. Weight loss is heavily dependent on energy expenditure. Resting energy expenditure (REE) after sleeve gastrectomy has been described in the literature with varying results. In this review, we review all published literature that described REE post sleeve gastrectomy in human. We found that REE goes down after sleeve gastrectomy as the weight loss occurs and REE when adjusted for weight (REE/kg) only goes up significantly in the 2 studies that included youths. REE/kg did not significantly change in studies including adults ages 30 and above. This study is the first that reviews and summarized REE findings post sleeve gastrectomy and more studies are needed especially targeting the pediatric and youth populations.
