I had been suffering from low iron for 16 years and visited two doctors at that time no cause was ever mentioned. After moving down the south coast and donating blood and told my iron was low. And after visiting a new doctor, testing for coeliac was mentioned. The blood test confirmed the results as did a test at the hospital. That was 11 years ago. I have always been a very health-conscious and active person and have never been sick other than head colds and a bout of flu and shingles twice. There were never any other symptoms that I was aware of. However, I was not aware I may have had brain fog until sometime later on a strict coeliac diet my brain cleared.
