Aerophagia may not cause gastroesophageal reflux

摘要

With interest we read the findings of Shepherd et al.,1 “Symptoms of Aerophagia are Common in Patients on Continuous Positive Airway Pressure Therapy and are Related to the Presence of Nighttime Gastroesophageal Reflux.” Shepherd et al. examined the prevalence of continuous positive airway pressure (CPAP)-associated aerophagia utilizing patient questionnaires to identify symptoms of gastroesophageal reflux (GER) and aerophagia in CPAP users. One of the authors' conclusions is that the presence of aerophagia symptoms is the strongest predictor of GER symptoms and vice versa.
