Hi I am 61 I was diagnosed with coeliac disease just before last Christmas. I am having problems needing to sleep up to 12/13 hours a day. I have paid to have a full thyroid panel and the results are good. Can anyone shed any light as to why I am sleeping like this. As soon as my head hits the pillow I am asleep. I also have ataxia and there is a question mark as to whether it is coeliac ataxia. I belong to the ataxia group and I will be asking the same question there. i am surprised that the thyroid blood tests came back OK because of the tiredness and I have lost a lot of hair since December.
