Are all hernias dangerous?

No.: A "hernia" commonly refers to a weakened area of the abdominal wall muscles. The resulting defect essentially provides a hole through which a loop of intestine can slide. This situation becomes dangerous if a loop of intestine becomes stuck outside the abdominal wall, leading to obstruction (blockage) or in worst case cutting off the blood supply to that segment of the intestine.

No: Some hernias are monitored or watched if the risk of complications is low.
