Thanks! It's some help. I'm working on asking a handful of other people involved in the Deaf community too, but no one so far seems to have any suggestions besides to fingerspell them. I may just fingerspell them and then use the signs you mentioned you did above, but I'm not sure yet. Thanks for the help and the ideas! It's not that I can't explain what celiac disease is, it's just that I'm a little more limited in the vocabulary I can use to explain it to Deaf friends in ASL in a way that makes sense to them.
