My 7 year old was dagnosed with aspergers and had the worst nosebleeds that seem to come more than they are not here. I had him on a gluten free diet since september and he had not one nose bleed. Because of testing he is having today I introduced gluten a week and a half ago and two days ago the nosebleeds started again. I don't know if there is a link between two or not but it is my observation.
You never know what is going on in our bodies.
