My stomach is F'd.

This morning I had a gastroscopy. It was a follow up from a year ago when I was in the process of discovering that my gall bladder doesn't work. Things are still icky; to be specific, gastritis, ulcers, and the worst part: an irregular z line. The doc didn't say it is out and out Barrett's espophagus, but I got the impression he'll be monitoring it indefinitely. Frankly, it scares the crap out of me. The frustrating thing is that I don't get heartburn since I had my band. So, was this damage done before I had my band? Or, have I caused it since by pouch packing and the like? Ugh. Bottom line: one more piece of motivation to eat correctly.
