Intussusception is the sliding of one part of the intestine into another.
This article focuses on intussusception in children.
Causes, incidence, and risk factors
Intussusception is caused by part of the intestine being pulled inward into itself. This can block the passage of food through the intestine. If the blood supply is cut off, the segment of intestine pulled inside can die.

The cause of intussusception is not known, although viral infections may be responsible in some cases. Sometimes a lymph node, polyp, or tumor can trigger the problem. The older the child, the more likely such a trigger will be found.
