What this Trial Is About
Bariatric surgery (BS), especially procedures like Sleeve Gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), is the most effective treatment for obesity. Yet, the exact mechanisms governing its effect are somewhat elusive, with current research mainly focusing on post-operative food intake outcomes based on self-reported data, which might not fully capture the nuanced changes in eating behaviours. To address these gaps, our study plans to employ the newly developed "drinkometer", a device capable of analysing the intricate changes in drinking behaviour following BS. This tool promises to bring a more detailed perspective to the changes in ingestive behaviours, bypassing the inaccuracies of self-reporting methods. By expanding our research to encompass diverse patient demographics and examining potential links to physiological shifts like gut hormone level alterations, the study aims to provide a more rounded understanding of the long-term impacts of BS on eating behaviours.
