What is irritable bowel syndrome?

Irritable bowel syndrome is a bothersome, but harmless condition with altered sensation in the colon and disturbance of bowel movements. The predominant symptoms are pain, bloating and alternating stool consistency (constipation and/or diarrhea). The symptoms occur frequently after meals and may increase during the day; they are typically worse in the evening. In relation to stress they can worsen significantly. Irritable bowel syndrome is three times more common in women than in men.
