Causes

• The most common cause is gastroesophageal reflux disease (GERD). If caused by GERD, the diseases is also called reflux esophagitis.
• Other causes of esophagitis include infections (most commonly candida, herpes simplex and cytomegalovirus). These infections are typically seen in immunocompromised people, such as those with AIDS.
• Chemical injury by alkaline or acid solutions may also cause esophagitis, and is usually seen in children or in adults who attempt suicide.
• Physical injury resulting from radiation therapy or by nasogastric tubes may also be responsible.
