I wish I could track down some actual stats for you (can't seem to find any), but many (half to more) with celiac diseaes do not show digestive symptoms. They may be completely asymptomatic or have 'atypical' symptoms that don't necessarily set off flags for celiac disease.

The truth is that "classic or typical" symptoms of celiac disease are not the norm! In the not too distant past, only the worst of the worst were ever diagnosed, often near death. Newer antibody tests developed over the last ten/fifteen years have really helped the diagnostic process and many more are being diagnosed. Still, they say, something like 95% remain undiagnosed .

It will be interesting to see what shows up on biopsy. Be sure to keep eating gluten until then... if a biopsy is scheduled. You wouldn't want to 'heal' prematurely and then have to question the biopsy results. No matter what the biopsy says, though, your antibody tests show significant gluten sensitivity...so ultimately, gluten free no matter what seems to be the best bet.
