Very recently, (within the last year or so) I believe I might have developed either lactose intolerance or a wheat/gluten sensitivity. I can eat slices of cheese and feel fine, along with bread, but it seems when there is a lot of cheese combined with wheat (such as macaroni and cheese or cheese pizza) I get horrible cramps, bloating and a feeling like there is a giant rock in my stomach. Sometimes I will get diarrhea that comes with severe cramping after a meal, but that seems to be really random and I cant find any pattern for it. I've had that symptom for many years now, it used to happen quite often to me but now it's uncommon that happens. I guess my question is, is it even possible to suddenly develop gluten or lactose intolerance? Is there any way to tell a key difference between the two (such as what part of the abdomen feels pain)? I get the cramps always in my lower abdomen. Also, does eating less wheat for a while and then suddenly eating it again cause higher sensitivity? I was trying a wheat free diet for a little bit last year, and then suddenly went back to including it in my diet again.
Thanks for reading!
