Barrett’s and GERD

Barrett’s esophagus is a condition where the normal cell lining (stratified squamous epithelium) of the food pipe (the tube that connects the mouth to the stomach), or a segment of it, is replaced with a different tissue similar to the lining of the intestine. The transformation is called intestinal metaplasia. This occurrence is rare and affects about 1.6 to 3 percent of people. In rare instances and in some individuals, this becomes a precancerous risk.
