Binge Eating, Depression and Anxiety Outcomes After Sleeve Gastrectomy Versus Gastric Bypass: A Cohort Study
The goal of this clinical trial is to learn if the type of weight-loss surgery (sleeve gastrectomy or gastric bypass) affects binge eating, depression, and anxiety in adults with severe obesity. The main questions it aims to answer are: Does sleeve gastrectomy lead to different changes in binge eating compared with gastric bypass? Does the type of surgery lead to different changes in depression and anxiety symptoms? Researchers will compare people who have sleeve gastrectomy with those who have gastric bypass…

About this study
The goal of this clinical trial is to learn if the type of weight-loss surgery (sleeve gastrectomy or gastric bypass) affects binge eating, depression, and anxiety in adults with severe obesity. The main questions it aims to answer are: Does sleeve gastrectomy lead to different changes in binge eating compared with gastric bypass? Does the type of surgery lead to different changes in depression and anxiety symptoms? Researchers will compare people who have sleeve gastrectomy with those who have gastric bypass to see if there are differences in binge eating, depression, and anxiety levels up to 12 months after surgery. Participants will: Complete questionnaires about eating habits, mood, anxiety, general health, and body image before surgery. Undergo either a sleeve gastrectomy or a gastric bypass operation (both are standard care). Follow a standard post-surgery diet plan. Attend follow-up visits at 1 week, 2 weeks, 1 month, and then monthly for 12 months, where they will complete the same questionnaires again.
Interventions
- Procedure: Laparoscopic Sleeve Gastrectomy — Laparoscopic sleeve gastrectomy performed using a 36-French bougie. The greater curvature of the stomach is resected, creating a tubular gastric sleeve. Standard perioperative care including antibiotic prophylaxis and DVT prophylaxis. Postoperative liquid diet for 15 days, then soft diet for one month, followed by gradual introduction of regular diet avoiding fatty and high-sugar foods.
- Procedure: Gastric Bypass — Gastric bypass surgery performed either as Roux-en-Y gastric bypass (RYGB) or one anastomosis gastric bypass (OAGB) based on preoperative multidisciplinary evaluation. Includes creation of a small gastric pouch and an anastomosis to the small bowel. Standard perioperative and postoperative care same as sleeve gastrectomy.
