What is a "strangulated hernia"?

A “strangulated hernia” or “incarcerated hernia” is a type of hernia where a piece or loop of intestine comes through a weakened portion of the abdominal musculature and as a result blocks or cuts off the blood supply to the section of bowel, and the lack of blood means a lack of oxygen, and without oxygen the tissue has the potential of dying very quickly, causing a surgical emergency where repairs would need to be carried out to cure the strangulated hernia.
