Lately, I seem to have irregular bowel movements mainly caused psychologically. Whenever I think about having a bowel movement in a matter of time, regularly half an hour, I need to go to expel waste. It makes it quite hard to deal with during school.
I am also a runner. Anytime I go for a run over 2 miles I get diarrhea and have horrible stomach cramps. I've had to drop off the cross country team because of this problem. Imodium works but I can't use it everyday when I need to get miles in for running.
