I've been browsing the board, and I want to pass this on.
If you think your child may be coeliac, don't cut out gluten until they have been tested. This is not just the blood test but the gastroscopy as well.
My DD became very Ill aged about 7. The process was quite gradual. One day, I decided enough was enough.
The doctor suggested coeliac, took blood and told me she would need a gluten free diet which we started immediately.
FFW six weeks to Great Ormond St hospital and a very upsetting interview with a paediatrician. As we had taken DD off gluten, the damage had abated and she would need to eat it again for three to six months. A row ensued, with the dr telling me that I was unreasonable, and IF she had a child she would do this, and if I didn't we wouldn't get a free food prescription. We left. Without our prescription.
It has been five years, and our new GP has just given us the prescription. We have managed without it, but shouldn't have needed to. It's hard to watch your child being I'll on gluten, but we have never had a 'formal diagnosis' and all through bad advice.
