A hernia  develops when a weakness that forms in the abdominal wall enables part of the intestine  (bowel) or another organ to protrude through it. Among the most common are umbilical  hernias that occur at the navel and inguinal  hernias that are seen in the groin area. There are 2 types of inguinal hernia, indirect  and direct , that may look similar but have different locations of the protruding intestine. Incisional hernias occur where an incision has been made in the abdominal wall for an operation.
