Proximal and distal gastro‐oesophageal reflux in chronic obstructive pulmonary disease and bronchiectasis

Abstract

The prevalence of GOR in COPD or bronchiectasis is twice that of the control population, and the diagnosis could not be based on symptoms alone. Pepsin was detected in sputum in COPD and bronchiectasis, suggesting a possible role of pulmonary aspiration, which requires further exploration.
