Irritable bowel syndrome:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
This functional disorder is generally associated with psychological stress; however, it may result from physical factors, such as diverticular disease, ingestion of irritants (coffee, raw fruits or vegetables), lactose intolerance, laxative abuse, food poisoning, or colon cancer. Some patients may experience a disturbance in the movement of the intestine or a lower tolerance for stretching and movement of the intestine.
IBS affects 10% to 20% of U.S. residents and has a yearly incidence rate of 1% to 2%. The condition occurs most commonly in women ages 20 to 30.

About prevalence and incidence statistics:
The term 'prevalence' of Irritable bowel syndrome usually refers to the estimated population
of people who are managing Irritable bowel syndrome at any given time.
The term 'incidence' of Irritable bowel syndrome refers to the annual diagnosis rate,
or the number of new cases of Irritable bowel syndrome diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
