Does exercise change your bowel movements?

Every time after exercise I get diarrhea. Does exercise change your bowel movements?

During and after exercise, your body secrets hormones that can cause change in your bowel movement. Any persistent or bloody diarrhea needs to be checked out with your pcp.
I would need to know more before speculating on a cause of diarrhea after exercise. There is a condition that used to be called runner's diarrhea, which happens in long distance runners who experience some lack of blood flow to the colon (ischemia), but this is rare. In general exercise should not cause diarrhea. Maybe something is being consumed around the time of or during exercise that is causing diarrhea?
