Guess coeliac disease is ruled out then :-/
I'm guessing the ulcers which showed up on your pill cam don't particularly look like Crohn's ulcers. I'm very far from being an expert, but Crohn's disease does tend to present with certain features that are typical to it; 'cobblestone' appearance, thickening of the bowel wall, 'skip' areas (ie healthy parts of the bowel in between diseased parts), etc.
Is it possible that this could be
early Crohn's disease, with the ulcers being early apthous ones? I'd ask your GI docs that question.
I knew there was more than one IBD, e.g. UC, lymphocytic colitis, but not of the small bowel. Wiki lists a few of them, but all are various forms of colitis apart from one...
