The Effect of Obstructive Sleep Apnea on Medical Outcomes After Gastric Bypass Surgery
The Effect of Obstructive Sleep Apnea on Medical Outcomes After Gastric Bypass Surgery
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.
Inclusion Criteria:
