Hello, I have been experiencing this for about 7 years on and off. When I first noticed my symptoms I was 13 years old. Every morning after breakfast I would have bad cramps and sometimes after lunch at school. Back then it was more on the mild side. Now I am 20 years old and experiencing this nearly every time I put something in my mouth, even a few crackers. Now it is way more debilitating. I cannot function for hours after eating sometimes. I have a bowel movement 30 minutes - 1 hour after eating. My discomfort is NOT relieved from a BM, actually it seems worse after. I have cramps, nausea, sometimes diarrhea. Never constipation. Also dull pains in my navel. Sometimes it's so severe I can't walk or talk. Anyone with any suggestions about this?
