Irritable Bowel Syndrome Epidemiology and Causes Quiz

IBS affects the large intestine and is associated with abdominal pain and discomfort. It is most common in ages 20-30 and predominantly affects young women and men.

The specific causes of IBS are not known, but factors such as irregular muscle contractions in intestinal walls, nervous system abnormalities, gut microflora changes, severe infection, family history, and stress might play a role.
