- Abstract
Aim: The aim of this study is to compare the differences in body composition in patients with obesity with successful weight loss (SWL) and unsuccessful (USWL) 1 year after Roux-en-Y gastric bypass (RYGB).Methods: We included 36 women and 22 men. After stratifying patients according with SWL (defined as ≥ 50% of excess weight loss), fat-free mass (FFM) and fat mass (FM) trajectories were analyzed in each group.Results: The %FM in SWL women (78%) was lower than USWL (36 vs. 44, <italic>p</italic> < 0.001). The %FM in SWL men (77%) was lower than USWL (27 vs. 38, <italic>p</italic> < 0.05). A lower %FM before surgery increased the probability of success (<italic>p</italic> < 0.05).Conclusions: SWL patients have a lower %FM, and those with lower pre-surgical %FM are more likely to have SWL 1 year after RYGB.
