RecruitingDevice studyMetabolic Endpoints for Obstructive Sleep Apnea Following Twelfth Cranial Nerve StimulationThe purpose of this study is to determine if the treatment of Obstructive sleep apnea (OSA) by hypoglossal nerve stimulation (HGNS) will alter glucose metabolism. The study team will also determine if the treatment of Obstructive sleep apnea (OSA) by (hypoglossal nerve stimulation) HGNS will alter predictors of cardiovascular outcomes.
