Barrett's esophagus is caused by acid reflex in the esophageal lining. It is classified as low or high grade
Barrett's, with or without dysplasia. It is precancer of the esophagus, but the risk is low, like any where
from 1% to 10%. they only due a endscopy every three years to watch it. If it goes into dysplasia they
probalby will burn it off the esophagus lining, which I have been told works well. The best theing to do
is avoid any food or drink that is acidic. I have Barrett's and I cut out allmost all algohal and diet drinks,
and watch what I eat especially not eating before bedtime.
