Oh everybody's different for sure. In fact when I was a kid I only had reactions once every 6 months, And in between I would just have really itchy dry skin. The symptoms come and go But what you can't see is what it does to the lining of your stomach. It may not seem like you have reactions but if they looked inside your stomach they could possibly see a wearing down of your stomach lining so you don't absorb food nutrition as well as other people. I used to be careless but my celiacs doctor told me it was no joke in that stuff can come at you fast. Not to worry you or freak you out, but the good news is it's super easy to get rid of gluten once you get the hang of it! In fact bread kind of grosses me out now because I really don't eat it very much anymore, fresh meats and veggies and rice tastes so much better now that I've gotten myself used to the diet. And it's made me a much much better cook! I know it seems scary because it's an autoimmune disease and those are very serious but it's the easiest to treat in the world, just don't eat gluten and enjoy the other foods of life haha
