What the study is about

The purpose of this research study is to see if obstructive sleep apnea (OSA) is associated with abnormalities in fat metabolism. Through this research study, the Investigator will evaluate how fat is metabolized in people with and without sleep apnea, what substances the fat tissue releases, and how these substances might change the way the body uses energy and sugar.

Being studied: PAP Therapy; Lifestyle Counseling Intervention

Conditions: Obstructive Sleep Apnea; Fat Disorder
