Causes and Symptoms of Stomach Ulcers
The liquid from the stomach that refluxes into the esophagus damages the cells lining the esophagus. The body responds in the way that it usually responds to damage, which is with inflammation (esophagitis). The purpose of inflammation is to neutralize the damaging agent and begin the process of healing. If the damage goes deeply into the esophagus, an ulcer forms. An ulcer is simply a break in the lining of the esophagus that occurs in an area of inflammation. Ulcers and the additional inflammation they provoke may erode into the esophageal blood vessels and give rise to bleeding into the esophagus. Occasionally, the bleeding is severe and may require transfusions of blood and endoscopic (a procedure in which a tube is inserted through the mouth into the esophagus) or surgical treatment.
