Barrets esophagus. Doc said he thinks pathologist over read b/c he sees no signs of it... Can it be reversed with nexium (esomeprazole)? He gave me 40mg 2xday

Possibly. High dose PPI's can prevent progression of Barrett's Esophagus to Cancer, and possibly reverse abnormal cellular changes in esophageal tissue. It is also possible that your GI i correct that Path over-read biopsy.
