I have celiac. It is very possible to have celiac disease without GI symptoms, in fact it is quite common.

Anemia and osteoporosis/osteopenia are frequent symptoms in females with celiac. Biopsy is no longer considered the "gold standard" of testing.

The National Foundation for Celiac Awareness has some great info on their site.

And, a diagnosis of celiac disease is not the end of the world. You can live really well gluten free. The main thing for you, as you do not get GI symptoms, would be remembering and being very aware that even the slightest amount of gluten is causing damage. For people like me who do have GI symptoms, it's a quick and painful reminder when we are accidentally "glutened."

Good luck, and feel free to PM me if you'd like.
