<<Disclaimer: Verify this information before applying it to your situation.>> Thank you to all who responded. I am sorry this summary has taken so long. I received a few responses Two people wrote about giardia (parasite) One person about celiac and lactose intolerance I received a detailed response on Diseases Which Resemble Celiac Disease, taken from http://www.celiac.com/similar.html, although, not all the diseases are discussed and I do not know if they resemble celiac disease basd on gastro symptoms or biopsy results. I will have to look further. If I discover anything interesting< I will post it to the group Thanks to all Elaine ER
