tripletrouble posted a topic in Celiac Disease - Pre-Diagnosis, Testing & SymptomsI've been reading up on gluten sensitivity for the last few weeks and in my gut (no pun intended) I know I have this. I have fatigue, joint pain, brain fog, itchy rashes, hair thinning, etc... that has all gotten exponentially worse over the past 6 months or so. BTW, I'm almost 37. My question is this... since we don't have the greatest insurance I'm expecting that all the testing could be expensive for us, do you think it is absolutely necessary for me to go a doctor (GI?) for the full battery of tests (many of which are inconclusive from what I've read) if after I get myself on a Gluten-free diet, it seems to be the answer for me? Is there any real benefit of having a doctor make an"official" diagnosis? Thanks for any advice/opinions you have!!
