Irritable Bowel Syndrome Slide Cover
IBS was long dismissed as a psychosomatic condition.1 It has no clear etiology or pathophysiology, affects mainly women, and is not fatal.2
However, attitudes are changing as physicians learn more about the pathophysiology of IBS.
The incidence and prevalence of IBS have not been extensively monitored, so it is difficult to discern historical trends. Also, only a small proportion of IBS sufferers seek treatment,3 and diagnosis of the condition is difficult.4

IBS is one of over 20 functional gastrointestinal (GI) disorders.1 The functional GI disorders vary clinically and are characterized by chronic or recurrent symptoms not explained by structural or biochemical abnormalities. It appears that these disorders relate to abnormalities in motility and/or afferent sensitivity as modulated by the central nervous system.2
IBS is defined as a functional bowel disorder in which abdominal pain is associated with a change in bowel habit with features of disordered defecation.3
Features of disordered defecation include3
Urgency
Altered stool consistency
Altered stool frequency
Incomplete evacuation
