How Does Bariatric Surgery Affect Social Experiences and Well-being - The BaSES-study
How Gastric Bypass and Sleeve Gastrectomy Change Social Experiences and Biomarkers of Well-being
Source: ClinicalTrials.gov · Last updated 22 Sept 2026
Brief summary (registry, in English)
Nonrandomized controlled trial to assess whether or not sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) affect social experiences and biomarkers of well-being 6 weeks and 1 year after surgery. The decision whether SG or RYGB will be performed is determined by medical decision making. Hypotheses: Bariatric surgery influences social experiences and well-being through changes in body image, reward responsivity and gut hormones. These changes may differ between gastric bypass (RYGB) and sleeve gastrectomy (SG).
