Risk factors for intussusception include:

  • Age. Children are much more likely to develop intussusception than adults are. It's the most common cause of bowel obstruction in children between the ages of 6 months and 3 years.
  • Sex. Intussusception more often affects boys.
  • Abnormal intestinal formation at birth. A condition present at birth (congenital) in which the intestine doesn't develop correctly (malrotation) also is a risk factor for intussusception.
  • A prior history of intussusception. Once you've had intussusception, you're at increased risk to develop it again.
  • AIDS. There is some evidence of an increased incidence of intussusception in people with acquired immune deficiency syndrome.
