What this trial is about
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.
