Overview

It has been shown to date that obesity is associated with increased mortality and that weight loss significantly improves cardiovascular risk factors. Among patients receiving bariatric surgery, 30-90% have moderate to severe obstructive sleep apnea (OSA) syndrome. Given the strong associations between OSA and cardiometabolic comorbidities, this project is based on the hypothesis of a lower improvement of cardiovascular risk factors and a higher number of post-surgical complications in OSAS patients.
