hi, my daughter is about 8 years and every after 1 or 2 months she suffers from stomach problem like vomiting and have intestinal pain. Doctors suggested to do anti tranglutiminase test which has come negative as she had severe vomiting and diarrhea and was not eating wheat for one week.But still she has celiac disease symptoms like short height,very slim body ,bloting, constipation,low heamoglobin, vomiting or diarrhea problem.So doctors suggested to give her gluten free diet for 2 months and check if some change come as i am not willing to do biopsy.But now she is having severe allergy on her body like redness itching and some mosquito bite pimples on her body and then they disappear after 25 min.I dont know whether she has celiac and change of diet has done allergy or its cause of medication during her vomiting problem.
