It is not always known what causes irritable bowel syndrome, but some of the suspected factors are thought to be related to diet intolerances, possibly due to allergies, the ability of the food to effectively pass through the gastrointestinal tract, and mental distress.

The digestive tract containing the stomach and intestine
A condition characterized by difficulty with normal defectation
The whole system involved in digestion from mouth to anus
