Barrett's Esophagitis in Anorexia Nervosa Binge/Purge Subtype

A prospective cohort study to assess the presence of BE in those with purging behaviors from their eating disorders has not been completed. There are multiple case reports describing a younger population not meeting typical screening guidelines whom developed this condition. To better define the presence of Barrett's esophagus (BE) via non-endoscopic testing in an eating disorder cohort with purging (vomiting/rumination) behaviors. Individuals with severe forms of eating disorders with purging and ruminating behaviors not meeting the current screening guidelines for BE will still test positive for BE.

• EsoGuard (Device): device used to collect esophageal cell samples to test for the presence of abnormal cells which may indicate a dx of Barrett's esophagitis.
