PointBlankGluten posted a topic in Celiac Disease - Pre-Diagnosis, Testing & SymptomsGood day from Australia and Merry Christmas to all. This is my first post although I've been reading on here for a long time. I'm sorry if I ask something very obvious but I couldn't find any information in searches. I believe I have Dermatitis Herpetiformes. My GP disagrees as my celiac blood panel was negative and the blister rash is on my chest and back and not elbows. I also have no gastro symptoms. My gluten free journey started when a natural therapist that I saw out of desperation to help with my 5 yr old son's behavioural issues put him on a gluten free diet. To support him I joined him on the diet and discovered how much better I felt for it. My fatigue improved significantly but for some reason my psoriasis got worse. I've been mostly gluten free for about 18 months now but my mother and other family members don't take my gluten issues seriously thinking of it as a fad. Their lack of support doesn't bother me so much as the family dinners where I get Glutened. For some reason the blister rash only appeared for the first time after 6 months of being already gluten free when I had a take away pizza that was meant to be gluten free but wasn't. I could tell by the rubbery base and the dough consistency and the immediate fatigue that set in. About 4 days later I started itching and stinging uncontrollably and thenof course the fluid filled blisters appeared, most of which left purple/white scars. Since then whenever I get gluten in I get the rash and it seems to be getting worse every time. It does disappear after being fully gluten free again. Going back in my family history and my late father's early passing, colon and stomach issues and my grandma's IBS and constant diarhea it doesn' take a lot to see the link. My question is : I already have a negative celiac blood screen and a GP who is irritated with me . I don't have it in me to fight a battle to get a diagnosis. The treatment would be the same anyway - go gluten free for life. However : what about nutritional deficiencies and absorption issues? Is that something that I should be concerned about? Are there reliable tests for nutritional levels that I can do irrespective of my Celiac concerns? I don't mind going back on gluten if it's going to mean getting a diagnosis but I just don't believe there's enough for a GP to go on as I'm so asymptomatic according to their rule books. Any advice or support greatly appreciated.
