Patterns of Weight Loss Response Following Gastric Bypass and Sleeve Gastrectomy

Background Despite the health benefits of bariatric surgery (BS) extend beyond WL, better understanding of the WL response may help improve the outcomes of BS. In this context, we aimed to assess patterns within the variability of weight loss (WL) after Roux-en-Y gastric bypass (RYGB) and sleeve gas...

Description
Summary:Background Despite the health benefits of bariatric surgery (BS) extend beyond WL, better understanding of the WL response may help improve the outcomes of BS. In this context, we aimed to assess patterns within the variability of weight loss (WL) after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). Methods WL data from 658 subjects that underwent RYGB ( n  = 464) or SG ( n  = 194) as first BS were analyzed. Based on excess WL (EWL), subjects were categorized as good WL responders (EWL ≥ 50 % at nadir weight and throughout follow-up), primarily poor WL responders (1-PWL:EWL
