Celiac is a disease from hell that pretty much equates to people that don't have it eating rat poison. That is what gluten does to a celiac. That's my story and I'm sticking to it!
All joking aside, it really depends who you are talking to. Are they going to understand the constant medical terminology associated with Celiac and all your other related health issues if you have them?
I worked in hospitals for 16 years so I have a lot of friends that understand all the medical related crap. I get into details with them All by other friends I try to explain the simplest way possible. Use words like allergic, medically necessary, explain just where gluten is found and what it does to your system. You don't have to get graphic, they don't need to know that you can finger paint with your poo and hit all colors of the rainbow in one day, but just the basics. I don't have a specific speech all laid out, but I hope that helps a little.
Pretty sure someone with a more vast experience with this will give the most perfect answer. I will also be awaiting to see what they have to say.
Oh, Bethie...you made my day!
I am still laughing!!!
All fun aside, I say "I have a disease that makes wheat, rye, barley and oats burn the lining of my somach like acid, and makes me sick for weaks over one crumb. Can you help me?"
I don't even need to name the disease.
