My son is not Autistic but has had PANDAS and when in a flare appears to be Autistic. His stomach has been a problem since day one, with horrible reflux, low stomach acid, treated yeast........ He ate gluten, carbs, and sugars with no problem as a small child but after PANDAS hit hard and I believe a virus of some sort too, after going off gluten, most carbs and sugar, my son finds now that he has a lot of anger, HORRIBLE brain fog, and if he eats those offending substances, it all gets 20 times worse. Did the yeast free diet for agfes with Duflican, he can't have yeast anymore. No antibiotics
