Abstract

Irritable bowel syndrome (IBS) is a complex, multidetermined syndrome involving altered gut reactivity, altered pain perception, and brain-gut dysregulation that is modulated by psychosocial and biological factors (Palsson & Drossman, 2005). The symptomatology of IBS is a combination of abdominal pain or discomfort, rectal distension, and altered bowel habit (i.e., diarrhea or constipation).
