How is GERD diagnosed?

Your physician will first want to rule out cardiac chest pain as the cause of your symptoms. In many cases, your gastroenterologist will be able to tell, based on the symptoms you describe, whether or not you have GERD. He or she also will have you undergo one or more procedures to help diagnose your condition and determine if there is any damage to the esophageal lining from reflux.

These procedures include an upper GI or esophagogastroduodenoscopy (EGD), a barium x-ray, esophageal pH monitoring, and esophageal manometry.
