Fast facts on hernias
Here are some key points about hernias. More detail and supporting information is in the main article.
Hernias often produce no troublesome symptoms, but abdominal complaints may signal a serious problem.
They are usually straightforward to diagnose, simply by feeling and looking for the bulge.
Treatment is a choice between watchful waiting and corrective surgery, either via an open or keyhole operation.
Inguinal hernia surgery is more common in childhood and old age, while the likelihood of femoral hernia surgery increases throughout life.
Overview: What is a hernia?
A hernia occurs when there is a weakness or hole in the peritoneum, the muscular wall that usually keeps abdominal organs in place.
This defect in the peritoneum allows organs and tissues to push through, or herniate, producing a bulge.
The lump may disappear when the person lies down, and sometimes it can be pushed back into. Coughing may make it reappear.
Smoking tobacco increases the risk of inguinal hernias.
