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.
