"A complex combination of elements, including psychological stress, hormones, the immune system, and chemicals called neurotransmitters, appears to interfere with messages between the brain and the bowel. The miscommunication causes abnormal muscle contractions or spasms, which often cause cramping pain. The spasms may either speed the passage of stool, causing diarrhea, or slow it down, causing constipation or bloating."
