A volvulus is when a loop of intestine twists around itself and the tissue that supports and connects it to the back wall of the abdomen. This cuts off blood supply and blocks the intestine. It must be treated right away.
The cause is not known.
Things that may raise the risk of this problem are:
Problems found at birth, such as:
A colon that is longer or larger than normal
A colon that is not attached to the abdominal wall properly
