hashimoto's disease and auto immune disorders?

It been really bugging me…

I know that Hashimoto's disease is an auto immune disorder along with a few other things…but what goes with this…is allergies to many foods, medications…

Type 1 diabetes is auto immune…is Type 2 also?…or the new version LADA? Im going to the doc later this month and its made me rethink my diagnosis…cause I went from pills to insulin in the last year…I could eat many things down to a wheat, multi grain and diary allergy…not to mention many veggies are off my list cause of diverticulosis…

Im going to do more research on this…makes you want to go HMMMM?????? WHY????
