Functional gastrointestinal (GI) disorders are common and affect approximately 35 million people in the United States. They account for 10% of visits to primary care doctors and at least 40% of visits to gastroenterologists. Irritable bowel syndrome (IBS) affects nearly one out of five people in the United States, from children to the elderly. The average age of onset of IBS is between 20 and 29 years of age. Each year, 2.6 million people seek treatment for symptoms related to functional GI disorders, and visits to physicians total 3.5 million.
