Extraesophageal symptoms are the result of exposure of the upper aerodigestive tract to the gastric juice. This causes a variety of symptoms, including hoarseness, postnasal drip, sore throat, difficulty swallowing, indigestion, wheezing, chronic cough, globus pharyngis and chronic throat-clearing. Some people with LPR have heartburn, while others have little or none of this symptom. This is because the material that refluxes does not stay in the esophagus for very long. In other words, the acid does not have enough time to irritate the esophagus.
 
Adults who are afflicted with LPR often experience the acrid taste of bile emanating from the back of their throat. This is also likely to be accompanied by a lump-like sensation in the throat, making it difficult to swallow. The throat may also seem to burn and breathing can be difficult. These symptoms are most often prevalent just after waking.
