That's true. I have run into the same thing. At times I get a little frustrated by all the research going on for other diseases. For example cancer is a multi billion dollar business. Where I go for treatments I almost feel like a second class patient. The cancer patients have access to all of these programs and support. Those of us with the rare diseases are often overlooked.
Still we need to realize that advances in these other diseases can still our diseases. For example, advances in stem cell therapies for other autoimmune diseases could help people like you who suffer from celiac disease. I have found that even when there is no specific information about your disease it is still possible to connect many of the dots. In my case it helps to have a wife who has multiple degrees in chemistry and biology. Combine that with my technical ability and we are a serious researching team. At times it is hard to sift through all of the information. The one thing I have really learned is that you have to take control of your disease. Sadly our doctors are not going to look out for us. It is our job to make sure we get the care we need and deserve.
