32 y/o female, no known major medical problems - depression, hay fever. Notice the past few times I've eaten pizza I get severe diarrhea, almost immediately. No nausea or vomiting, but stomach cramps, urgency and diarrhea. I wonder if I could be allergic to the wheat? I don't eat white flour or wheat very often and try to eat mostly low-glycemic/low-carb. Appreciate anything that could point me in the right direction. Thanks.
