Barrett's Esophagus

Definition

Barrett's Esophagus is a condition where the lining of the esophagus changes, often due to damage from acid reflux, and can increase the risk of developing esophageal cancer.

Scientific / Technical Definition

Barrett's Esophagus is characterized by the abnormal transformation of the tissue lining the lower esophagus, a process known as metaplasia. The normal squamous epithelium lining is replaced with columnar epithelium, typically due to chronic gastroesophageal reflux disease (GERD). This condition is considered a precursor to esophageal adenocarcinoma.
