Gastroesophageal reflux disease (GERD) is a frequent cause of consultations with gastroenterologists. Extra-digestive symptoms such as chronic coughing, laryngitis and chest pain are frequently associated with GERD. Chronic laryngitis is one of the symptoms most often associated with GERD, yet various studies which have used monitoring esophageal pH as a diagnostic tool have not found any clear association between chronic laryngitis and reflux. Moreover, studies which have treated patients suspected of having chronic laryngitis caused by reflux with proton pump inhibitors (PPIs) have had had rates of therapeutic failures. Symptoms continue to persist in these patients despite adequate inhibition of acid secretion. To date, no evidence exists of the association between chronic laryngitis and GERD, much less evidence of a causal relation. We consider that, although GERD may be responsible for some episodes of chronic laryngitis, it is not the illness most frequently associated with it, and in the many cases in which GERD has been reasonably ruled out, other potential causes must be investigated.
