Brief 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
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
Detailed Description: The study of the Nantes Bariatric Surgery Cohort NBC aims to evaluate the impact of bariatric surgery on biological age adipocyte dysfunction microbiota and biological rhythms in individuals with obesity This observational study will include 300 participants over 35 years It involves pre-operative peri-operative and post-operative visits to collect clinical biological and lifestyle data Key assessments include anthropometrics blood tests questionnaires and biocollections
