An epidemiological survey showed that respiratory symptoms with gastro-oeso
phageal reflux (GER) were twice as high as those without GER symptoms. In 4
6 cases of unknown chronic cough or asthma, 67% had positive oesophageal pH
monitoring. Of 34 patients with snoring and reflux symptoms, 16 (47.1%) we
re confirmed as positive for obstructive sleep apnoea (OSA) and GER. Antire
flux therapy significantly improved both GER and OSA.
