Weight regain following bariatric surgery: a systematic literature review and comparison across studies using a large reference sample

Published estimates of weight regain (WR) following bariatric surgery vary greatly. Understanding the sources of variability in the literature and clarifying the magnitude of WR following Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are critical for informing expectations and planning interventions. A literature search through January, 2019 yielded 15 English-language studies that reported WR in at least 30 participants, not selected based on weight loss or WR, at least 3 years following primary RYGB (N=11) or SG (N=5).
