The husband of a friend of mine has had it for years and didn't know it. He had lost so much weight and most of his food went right through him and caused him terrible stomach pains but he didn't realize that it was due to his diet because nearly everything that he ate caused those symptoms. It tends to run in families of Irish descent, which he is. My friend learned how to cook gluten free meals and he's so much better now. No more Friday night pizza, at least not the kind that they were having every week. There are several sites where you can get gluten free recipes and that has helped my friend plan meals. Good luck and let us know what the tests say.
