PURPOSE: It is known that nocturnal gastroesophageal reflux disease (N-GERD) has been observed in patients with obstructive sleep apnea syndrome (OSAS). The responsible mechanisms are not clear as of yet, however obesity, increasing abdominal movements with increasing gastric pressures during apneic events, relaxation of esophageal-gastric sphincter, thoracoabdominal paradox, stimulation of vagal reflexes attributed to acidic esophageal pH, have all been reported. Despite that association, N-GERD has not been included as a question in any of the widely used screening questionnaires for OSAS (such as Berlin, STOP-Bang etc). This study aimed to assess the predictive value of frequent (> 5 times/month) N-GERD as reported by the patient.
