Question: What Causes Esophagitis?
Answer: It is most often caused by acid-containing stomach contents refluxing back up into the esophagus. The most significant cause of acid reflux is gastroesophageal reflux disease. Other causes of reflux are hernias, vomiting, medications and surgery.
Esophagitis can also be caused by an infection that can develop in individuals with weakened immune systems, such as caused by HIV or certain medications such as corticosteroids. The infection can be caused by viruses, including herpes and cytomegalovirus, and fungi or yeast, especially Candida infections.
