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 \u201cMaintainers\u201d (WR \u226420% of %MWL) or \u201cRegainers\u201d (WR &gt;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 \u00b1 11 years and a mean body mass index of 44.6 kg\/m2. Mean WR at 10 years was 28% (\u00b125), higher in SG vs. RYGB (41.37% vs. 26.17%, p = 0.03). Overall, 56.7% were Regainers. Baseline type 2 diabetes mellitus (T2D) was associated with an approximately 40% reduced risk of WR &gt;20% (OR = 0.59; 95% CI: 0.38\u20130.93; p = 0.023). WR was not significantly associated with the recurrence or remission of T2D, hypertension, or dyslipidemia. Conclusion: WR is common a decade after BS, particularly following SG. While WR does not appear to significantly impact comorbidity recurrence, its clinical relevance warrants further study. Standardized definitions are urgently needed to guide long-term management.
