Core Tip

Core Tip: Metabolic and bariatric surgery (MBS) is an evidence-based treatment for morbid obesity that contributes to sustainable weight loss over long-term periods. Unfortunately, post-MBS weight regain (WR) still occurs at a considerable rate, and its incidence continues to increase annually. This review summarizes updated information on weight trajectories after MBS, definitions of postoperative WR, factors contributing to postsurgical WR, and strategies to prevent WR after sleeve gastrectomy or Roux-en-Y gastric bypass.
