What exactly is a hernia?

See below: A hernia is most commonly a weakness of the body fibers in the abdominal wall. Most common sites for hernias are groin and umbilical region. There is a weakness in the abdominal wall fibers, resulting in some of the internal body tissue or intestines to protrude through the weakness. Groin hernias more common in men, umbilical in both men & women.

A fascial tear: All hernias are caused by a disruption in the fascia of the abdominal wall. Fascia is a strong sheet of connective tissue that extends from the top of you abdomen (where it meets your chest) down past your groin. The fascia is the strength layer of your abdominal wall. It is responsible for keeping your abdominal contents in your abdomen. A hernia is a hole in your fascia.
