DIFFERENTIAL DIAGNOSIS — Gastroesophageal reflux disease (GERD) needs to be distinguished from infectious esophagitis, pill esophagitis, eosinophilic esophagitis, peptic ulcer disease, non-ulcer dyspepsia, biliary tract disease, coronary artery disease, and esophageal motor disorders. Symptoms alone do not reliably distinguish among these disorders [18]. Similarly, the severity and duration of symptoms correlate poorly with the severity of esophagitis.

Dysphagia may be due to GERD, but slowly progressive dysphagia for solids with episodic esophageal obstruction is suggestive of a peptic stricture. Other, more common causes of dysphagia are reflux esophagitis, eosinophilic esophagitis, and impaired peristalsis. Another, fortunately rare, cause of dysphagia is esophageal cancer, either adenocarcinoma arising from Barrett's metaplasia or squamous cell carcinoma.
