I know it's been about 6 months since you posted this, but I hope you get this message. I am currently being tested for celiac because my docs just cannot figure out what is going on with me. I furst thought all of this was caused by the Mirena IUD (which was removed 5 months ago) but the symptoms did not go away. Friday I had an EGD and they took biospies of my small intestine - completely safe and painless procedure. Apparently you can have this done to confirm celiac, but there are some specific anitbody tests you can have done as well - simple lab work. Here is a list of my symptoms. Hope it helps.
