Anecdotal evidence suggests that anxiety disorder may contribute to the irritable bowel syndrome (IBS), a condition characterized by nausea, alternating constipation and diarrhea, and no identifiable gastrointestinal pathology. Researchers administer an online questionnaire regarding IBS symptoms to 10,000 people who have an established diagnosis of anxiety disorder in the United States, Canada, and Mexico. They administer the same questionnaire to another 10,000 people from the same countries who do not have a diagnosis of anxiety disorder. Their findings are tabulated below.
