My DD was diagnosed as coeliac last April (2022) when she was 6. She was diagnosed via blood test, and her TTGA level was over 250. We started the GF diet and her main issues (headaches, heartburn and horrible stomach pains and diarrhoea) soon subsided. We saw the consultant in December and her TTGA level was down to 26.
Recently, she has been getting random episodes of diarrhoea and heartburn - literally before her diagnosis, the heartburn was around once per week, now it's probably once per 3 months. In the last few weeks however, she's had it 3 or 4 times.
I've spoken with the dietitian who has recommended that she has a blood test to check her gluten levels as she shouldn't be experiencing symptoms of glutening if she is GF. As a household, we are now GF as my DS is also coeliac (diagnosed after DD but never showed symptoms and he was diagnosed via OGD in Sept 22).
DD does have school dinners and we have been reassured countless times that the kitchens (who make and bring in the food to the school) are preparing it all in a separate area / it's all GF. Thinking back, I'm sure her symptoms started when she went back to school after Easter half term, but the school are adamant they are giving her GF food.
I know it can take up to 6 months for the gut to repair, but does anyone have experience of their VERY coeliac child still experiencing glutening type issues even after they go on a GF diet? We are very strict at home with GF but I don't know if perhaps because she was so poorly pre-diagnosis, that her gut is taking longer to heal? She has been GF for 13 months now. She has always had a bad tummy - when she was little she would have lots of diarrhoea (they classed her as having toddler's diarrhoea).
