Thanks for your reply tatt. I have been to bed, but couldn't sleep. I was mulling over the fact that he is now half-way through the time he needs to be on gluten before the test and maybe it would be wrong to quit now, but he and our family are suffering so much and I can't see him coping at school for most of the summer term like this.
We can cope without the prescription food - just, as we had been doing so for 4 months while he was on the exclusion diet. We just tended to eat a lot of healthy home cooked food and I baked using doves farm flour for treats. The most expensive thing was bread for his lunch-box, as he would only eat the Genius stuff and it's not cheap.
I did know it could be genetic, but somehow hadn't made the connection to other family members needing to be tested. Its always been fairly obvious in ds as his bowels have never been normal, right from weaning onwards. His brother and sister don't suffer in the same way though although I have just read that some people can be coeliac and asymptomatic.
I didn't know about the osteoporosis risk, but was aware that there can be problems in later life due to lack of absorption of the right nutrition.
Interestingly my Mum has just been advised to give up wheat and she's also recently been diagnosed with osteoporosis. Dh also has quite bad digestive problems that have always been put down to IBS and he has been thinking about asking to be referred for testing. His mum also suffers with her digestive system in a similar way.
I assumed ds didn't have dermatitis herpetiformis as he generally has good skin. He does however get a pimply rash on both cheeks which feels rough to the touch and gives him a sort of rosy cheeked appearance when he has gluten. I've looked at quite a few images of DH though and it looks nothing like it.
I'd heard about enzymes, but wasn't sure where to get them or what the benefits would be. Can you buy them in good health shops? He is already on pre and probiotics and a good quality supplements.
