Scientists probe the link between obesity and sleep apnea
NCT ID NCT04793334
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 106 people with obesity who were scheduled for weight-loss surgery. Researchers measured how their upper airways behaved during sleep and used MRI scans to see if changes after surgery could explain why some develop obstructive sleep apnea and others do not. The goal was to understand the underlying mechanisms, not to test a new treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could help doctors predict which obese patients are at risk for sleep apnea and guide personalized treatments.
What could go wrong
This is an observational study, not a treatment trial. It may not lead to any new therapies, and results may not apply to all patients.
