The esophagus is a muscular tube leading from the back of the throat into the stomach. Esophagitis is an inflammation of the lining of the esophagus, caused by infection or irritation of the inner lining (mucosa) of the tube. Common symptoms include heartburn and painful swallowing. If undiagnosed or untreated, esophagitis can cause problems with swallowing, ulcers, scarring of the esophagus, or "Barrett's esophagus," which can be a precursor to esophageal cancer.
