<<Disclaimer: Verify this information before applying it to your situation.>> My two daughters have CD (ages 13 and 16). I remember years ago reading about a very serious condition called "Celiac crisis" in which the person becomes violently ill and can die if it is not known what is causing the illness. Does anyone have more information about this? Would it only be caused by ingesting gluten? Would it only be if it was a large amount ingested? What signs and symptoms would there be other than vomiting and/or diarrhea? My oldest daughter is going out of the country with a school group this summer and I want to send all the information I can with her. She is registered with Medic Alert and has a "dog tag" which she will wear. Thank you in advance. Jane inCA
