Gastroesophageal reflux disease (GERD) is commonly discussed in the pages of the IFFGD publication, Digestive Health Matters. Therefore readers will be familiar with the common consequences of acid from the stomach refluxing upwards into the unprotected esophagus. These include heartburn, unexplained chest pain (non-cardiac chest pain), and inflammation and scarring of the lower esophagus (esophageal stricture) leading to swallowing difficulty. However, this article deals with several seldom-described consequences of GERD that are not rare and which can cause great distress in their own right: sore throat, cough; nocturnal choking; aspiration pneumonia; asthma; acid laryngitis; dental erosions; reflux dyspareunia are discussed.
