ClinConnect Summary
The Nantes Bariatric Surgery Cohort study is exploring how weight-loss surgery, known as bariatric surgery, might affect the biological age of individuals with obesity. Researchers want to understand if this type of surgery can lead to improvements in how fat cells function, changes in gut bacteria, and better biological rhythms, and if these changes are connected to aging. To answer these questions, the study will collect samples from participants before, during, and after their surgery.
To be eligible for this study, individuals must be over 18 years old and have a body mass index (BMI) of 35 or higher with health complications, or a BMI of 40 or higher, regardless of complications. Participants must also agree to join the study and be part of a social security program. However, individuals who are pregnant, nursing, or under legal guardianship cannot participate. The study is not yet recruiting, but it aims to provide valuable insights into how bariatric surgery could improve health outcomes for people dealing with obesity.
