A hernia is tissue from inside the abdomen that bulges out through
a weak spot in the muscles of the abdominal wall. The weak spot may have been
present since birth or may develop following surgery, violent or chronic
coughing, lifting heavy objects, or from aging.
There are several types of hernias:
- A femoral hernia appears
as a bulge on the top of the thigh.
- A hiatal
hernia is a part of the stomach bulging up through the diaphragm (the wall of
muscle that separates the abdominal cavity from the chest
cavity).
- An incisional hernia occurs after
surgery to the wall of the abdomen.
- An inguinal hernia occurs when a small portion of the bowel
bulges into the groin.
- An umbilical hernia
appears in the belly button. A periumbilical hernia is
similar to an umbilical hernia, but occurs next to the belly button.
A person with a hernia often feels pain, pressure or burning, or a
feeling that something has given way.
