debbio posted a topic in Celiac Disease - Pre-Diagnosis, Testing & SymptomsHI. I have symptoms of celiac. The biggest to me is brain fog, hard to concentrate and memory issues (for at least 7 years now), my iron levels are very low. I have been on prescription iron supplements for 6 months and level is slowly rising, low Vitamin D, and Hashimotos. My 8 year old daughter is worried about her memory as well. I got my test results back by phone today and they said they are normal. igA is 1. she said anything <4 is normal. Transglutaminase AB1GG is 1 also. she said anything <6 is normal. I was thinking of trying to go off gluten for a week to see if we feel and think better. Wondering your suggestions? Thanks so much in advance!
