We are trying our 6.5yo on a gluten free diet to see if it helps with his frequent stomach ache, low appetite, and unusually high thirst. He's been gluten-free for a few weeks now. We haven't noticed a huge change with any of his symptoms so far. Meanwhile, he has been burping constantly. I wonder if it's behavioral thing...he says he can't help it, but maybe he's gulping air and doesn't realize? He will do a series of small burps, like 15 in a row. He is not autistic but is borderline SPD and does have a tendency towards stim behaviors. (Pulled out his hair as a toddler, skin picking, etc.) But I'm wondering if something about his new diet is causing the belching? Maybe his body is detoxing? He is not eating a ton of the bread substitute type stuff as he doesn't like most of it. He is eating more protein than before, and probably more fruit. Any ideas?
Oh, and he has been dairy-free since he was a baby.
