Obstructive sleep apnea: the effect of bariatric surgery after 12 months. A prospective multicenter trial

Obstructive sleep apnea (OSA) is a highly prevalent sleep disorder, particularly in bariatric patients. It is known to be tightly linked with metabolic abnormalities and cardiovascular morbidity. Obesity is the most noteworthy individual risk factor for OSA. The aim of this study was to investigate the effect of a laparoscopic Roux–en–Y gastric bypass (LRYGB) on OSA 12 months after surgery.
