Key result
Gastric bypass linked to ~6 kg/m² greater BMI reduction at six months versus sleeve gastrectomy.
Why the study?
An in-depth understanding of bariatric surgery outcomes and patient satisfaction had yet to be developed within the authors' community context.

Does Roux-en-Y gastric bypass improve BMI reduction and comorbidity resolution compared to sleeve gastrectomy in patients with obesity?
Absolute Event Rate: 17.49% vs 11.7%
p-value: p=0.002
Bariatric surgery, particularly gastric bypass, provides significant short-term reductions in BMI and high rates of remission for cardiometabolic risk factors like hypertension and type 2 diabetes.
Bypass was associated with greater BMI reduction than sleeve; leaves open differential cardiometabolic remission effects pending randomized trials.
Introduction:Obesity is a many-sided health problem affecting millions of people around the world, which require interventions to minimize its effect on human’s health and health care system. Bariatric surgery has appeared vital assist for copying with obesity and associated complications, but in-depth understanding of its outcomes and patient’s satisfaction has yet to be developed, especially within our community context.Objective; To compare the short-term effects of sleeve gastrectomy and Roux-en-Y gastric bypass on BMI reduction and resolution of obesity-related comorbidities.Materials and Methods:A retrospective cohort study was conducted at Zhyan Private Hospital, Sulaymaniyah, between December 2023 and April 2024. Data from 226 patients who underwent bariatric surgery were analyzed. Pre- and postoperative BMI, hypertension (HT), and type 2 diabetes mellitus (DM) were assessed. Statistical analyses were performed using SPSS v26.0; McNemar’s test was applied for paired categorical outcomes, and Chi-square tests for between-group comparisons.Results: Median BMI reduction was significantly greater in the bypass group (17.49 kg/m²) than in the sleeve group (11.70 kg/m²; p = 0.002). Both procedures produced significant remission of HT (from 40 to 13 cases; p < 0.001) and DM (from 17 to 3 cases; p < 0.001). No significant difference in absolute weight loss was observed between groups (p = 0.15).Conclusion:Bariatric surgery, particularly gastric bypass, was associated with marked BMI reduction and comorbidity remission within six months, supporting its role in managing severe obesity and metabolic disease in our population.

Ezzaddin et al. (2026) conducted a cohort in Obesity (n=226). Gastric Bypass vs. Sleeve Gastrectomy was evaluated on Median BMI reduction (p=0.002). Gastric bypass was associated with a significantly greater median BMI reduction (17.49 kg/m²) compared to sleeve gastrectomy (11.70 kg/m²) at six months post-surgery.
