The Effect of Obstructive Sleep Apnea on Medical Outcomes After Gastric Bypass Surgery
Not Recruiting
Trial ID: NCT00671983
Purpose
Obstructive sleep apnea (OSA) is a syndrome characterized by repetitive episodes of airway
obstruction during sleep, which result in low oxygen level in the blood and bad sleep
quality. Both of these effects are implicated in medical, neurological and cognitive
disorders in subjects with OSA. The purpose of this study is to examine how OSA affects
medical and neurobehavioral outcomes after gastric bypass surgery for weight loss in morbidly
obese patients.
