Associations Between Sleep Position and Nocturnal Gastroesophageal Reflux: A Study Using Concurrent Monitoring of Sleep Position and Esophageal pH and Impedance.

Introduction: The aim of this study was to investigate the effect of spontaneous sleep positions on the occurrence of nocturnal gastroesophageal reflux.

Methods: In patients referred for ambulatory pH-impedance reflux monitoring, the concurrent sleep position was measured using a sleep position measurement device (measuring left, right, supine, and prone positions).

Results: Fifty-seven patients were included.
