What are the common types of hernia?
The most common type of hernia is called an inguinal hernia. An inguinal hernia is caused by a weakness or defect in the lining of the abdominal (belly) wall or pelvic (groin) wall. It can be present at birth or develop over years. A hernia can also develop in the abdominal wall around a previous incision. This is called a ventral hernia.
