Hi Terri,
You know I frequent the PN board too, and I have celiac disease. I do believe that my PN was brought on my malabsorption because of celiac disease. There is a connection of one to the other. Some studies try to make it seem like they do not go hand in hand, but often they do.
Research is how we learn nearly everything. If you have any guestions, feel free to email me. I can try to answer them.
