Barrett's is when the lining of the esophagus becomes smooth - similar to that of the stomach lining. It is a condition that needs to be monitored, she should be checked every year - because it may be a pre-cancerous condition. I believe it is caused by the acid reflux - you should further research GERD on the internet. Good luck to you. I am actually having my first endoscopy tomorrow to check for similar condition.
