Basically, there were no polps, stenosis, no large lesions, so that is good. However, I'm still having intermittent bleeding (in fact I bled just last night), so the working diagnosis at this time is that I probably have a small ulcer somewhere that bleeds occasionally. The next step would be a more involved endoscopy, but my GI doesn't want to do anything about it right now, unless the bleeding increases or my hemoglobin/iron drops. He does recommend more regular blood tests to monitor my hemoglobin.
Now an incidental finding on the MRI was a 4cm ovarian cyst, which I am now supposed to get followed up with my GP. I have had cyst before, though I'm not sure I had one that large.
Overall, I guess I should be relieved that there weren't any more serious findings, but right now I'm just more confused.
