DEAR DOCTOR K: I have esophagitis. Could this have been caused by my acid reflux? What can I do about it?
DEAR READER: Yes, it could, and there are treatments. First, some explanation. The esophagus is the muscular tube that carries food from the mouth, through the chest and into the stomach. Normally you don't feel the presence of the esophagus, except when you are swallowing. Sometimes the lining of your esophagus becomes inflamed. That's called esophagitis. By far the most common cause of esophagitis is acid reflux, or gastroesophageal reflux disease (GERD).
