The result of unduly rapid transit of the bowel contents so that there is insufficient time for reabsorption of water to firm up the faeces. In consequence, the stools are loose and liquid and are passed more frequently than normal. The commonest causes are irritation from a bowel infection and psychological factors, as in the IRRITABLE BOWEL SYNDROME.

Travelers' diarrhea is defined as three or more unformed stools in 24 hours, commonly accompanied by abdominal cramps, nausea and bloating.

High-risk destinations are the developing countries of Latin America, Africa, the Middle East and Asia.
