DD1 (5.5) was diagnosed with coeliac disease when she was nearly 3 and ever since has obviously been gluten free. Her health is generally good and although she has a fairly narrow diet, and doesn't eat many vegetables, she eats loads of fruit and drinks lots of milk.
She doesn't seem to be as susceptible to all the illnesses that sweep through her class each week - her attendance in reception was 98%, but when she does succumb to a virus, she can be quite poorly.
This week she is really suffering with this horrid flu bug - really high temps, a horrid cough which has made her vomit a few times, and a nasty cold. She has been suffering for 4 days now. Her sisters have also had the bug but not nearly as badly.
My mother and MIL (who used to be a nurse) both reckon that the coeliac disease compromises her immune system and so it is inevitable that she will suffer more. I can't see that this should be the case - her paed has never mentioned this possibility and as she is totally gluten free, surely that means she is as likely as any other child to fall prey to any infection she comes into contact with.
Sorry for the ramble, I have posted a query to coeliac uk but they are closed till 2nd Jan. I'm just interested to hear what others think, whether based on science or personal experience .
