Persistent variability observed during spirometry, even when technical and personal factors
are controlled, has prompted interest in uncovering its underlying mechanisms. Notably, our …

Variability during spirometry can persist despite control of technical and personal factors. We
postulate spirometry induces gastro-oesophageal reflux (GOR), which may cause variability …

Background The interaction between the respiratory and gastrointestinal systems, and the
role of the latter in the development of respiratory pathology, has been examined with a …

Background Proof of the relationship between gastroesophageal reflux disease (GERD) and
respiratory symptoms remains a challenge. Our aim was to determine the association …

Abstract Background and Aims Exaggerated pressure fluctuation between the thorax and
abdomen during exercise or with pulmonary disease may challenge the gastroesophageal …

Background & Aims Normal responses of the upper esophageal sphincter (UES) and
esophageal body to liquid reflux events prevent esophagopharyngeal reflux and its …

Background Asthmatics are known to have esophageal hypomotility. Vagal hypofunction
and prolonged intra-esophageal acidification cause esophageal hypomotility. The …

BACKGROUND & AIMS: Many patients with gastroesophageal reflux disease (GERD) have
persistent reflux despite treatment with proton pump inhibitors (PPIs). Mixed gas-liquid reflux …

Background Impedance‐pH monitoring allows assessment of retrograde and antegrade
intra‐esophageal movement of fluids and gas. Reflux is followed by volume clearance and …

Aim: This research aimed to evaluate the effect of gastroesophageal reflux disease (GERD)
on pulmonary volumes, airflows, and airway resistance in the patients without respiratory …
