It is a hostile environment of hydrochloric acid. Mucus is the first line of defense in protecting the lining, but when acidity increases it can erode the lining. If the acid breaks through the lining, the secretion of another protein is stimulated, which increases the production of hydrochloric acid, thereby establishing a destructive cycle. Until recently, a bland diet was recommended to prevent and reverse this disorder, but now physicians treat most forms of the disorder with antibiotics instead.
