What this means
This is a plan to study people before and after weight-loss surgery. It has not reported any results yet, so it cannot yet show whether the surgery changes biological age.

Registry summary
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 :
- Whether bariatric surgery is associated with changes in biological age
- If bariatric surgery alters adipocyte dysfunction, the microbiota and biological rhythms
- 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
