Obesity is a risk factor for obstructive sleep apnea and central hypoventilation syndromes. Increasingly, bariatric surgery is being popularized as a means of weight loss and, to a lesser degree, as a novel therapeutic intervention for sleep apnea. In this talk, we present the preliminary results of a cohort of 220 patients undergoing bariatric surgery at California Pacific Medical Center in San Francisco followed for up to 18 months.

The primary sleep outcome for this cohort is their daytime sleepiness as measured by the Etworth Sleepiness Scale. We evaluate changes of weight, quality of life, and other predictors on sleepiness. We also present preliminary results from our systematic review of 116 studies of bariatric surgery on sleep apnea, including individual level patient data for 80 patients from 14 studies from which we evaluated specific demographic and clinical predictors of improvement in sleep apnea after surgery. We hope that our results may inform the current guidelines for preoperative evaluations of potential bariatric recipients and to identify those patients at greatest of failing to improve their sleep apnea after surgery so that targeted interventions may be developed for these individuals.
