Can treating sleep apnea fix blood sugar problems?
NCT ID NCT03408613
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at why sleep apnea raises the risk of diabetes. Overweight adults with and without sleep apnea will have their blood sugar control measured. Some will receive CPAP, some will get extra oxygen at night, and others will get a sham treatment. The goal is to find out if poor sleep or low oxygen is the main cause of blood sugar issues.
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 study could reveal whether lack of oxygen or poor sleep causes blood sugar problems in sleep apnea, pointing toward better treatments.
- What could go wrong
- This is an early-stage, suspended study with only 80 participants. Results may not apply to everyone, and the treatments tested may not improve glucose metabolism.
