Nantes Bariatric Surgery Cohort
Source: ClinicalTrials.gov · Last updated 3 Apr 2026
Brief summary (registry, in English)
While current research suggests that inflammation of adipose tissue in obesity is linked to accelerated aging, it has yet to be determined in humans how this could enhance preventative and personalized medicine for obese individuals. The NBC study aims to investigate : 1. Whether bariatric surgery is associated with changes in biological age 2. If bariatric surgery alters adipocyte dysfunction, the microbiota and biological rhythms 3. Whether changes in adipocyte dysfunction, microbiota and biological rhythms are linked to changes in biological age. To achieve this, establishing a biocollection before, during and after bariatric surgery will be crucial in addressing these questions
