Ten-Year Weight Regain after Bariatric Surgery: Prevalence, Predictors, and Metabolic Impact.

ABSTRACT:

Introduction

Bariatric surgery (BS) is an effective intervention for severe obesity, but long-term weight regain (WR) can occur and may impact comorbidity outcomes.

Methods

In this retrospective study, we analyzed patients who underwent BS with a 10-year follow-up. WR was calculated as the percentage of maximum weight loss (%MWL) that had been regained from the nadir weight. Patients were categorized as "Maintainers" (WR ≤20% of %MWL) or "Regainers" (WR >20%).

Results

Among the 353 included patients, 317 underwent Roux-en-Y gastric bypass (RYGB) and 36 underwent sleeve gastrectomy (SG), 90.4% were female, with a mean age of 42 ± 11 years and a mean body mass index of 44.6 kg/m2. Mean WR at 10 years was 28% (±25), higher in SG vs. RYGB (41.37% vs. 26.17%, p = 0.03). Ov
