How will barretts esophagus affect my health going forward?

May get worse. Barrett's esophagus results from damage to the lining of the esophagus due to gastric acid and enzymes backing up into the esophagus. It may cause bleeding, ulceration, scarring and over a longer time may result in cancer. Initial treatment is with antacids, but depending on the defect and extent of damage, it may be treated with surgery.
Problematic GERD. Barrett's esophagus is not something to play around with! barrett's epithelium occurs as a terminal event in those with chronic gerd. Barrett's patients risks cancer of the esophagus. Poorly treated barrett's can progress by replacing more & more of the esophagus lining, & can become dysplastic. Barrett's warrants surveillance endoscopy, aggressive acid suppression, & maybe ablation &/or surgery.
