Barrett's does convert eventually to malignancy, usually an andeocarcinoma. I have had it do so, as well as other here. This can be managed with a good gastro doc, and watched VERY ROUTINELY AND CAREFULLY WITH AN ENDOSCOPE PROCEDURE. This person should be on proton pump inhibitors, OTC h blockers as needed and for peak heartburn liquids like Maalox. But long term use of PPI's. like Prilosex, Nexxium etc. is a must to get this under control. There is also a surgical laproscopic procedure to tighten up the pyloric sphincter that I have had that helped some, but also caused new problems.
