Definition: A hernia is the protrusion of an
organ or tissue outside of the body cavity inside which it is normally
The most common type of hernia is the hiatus hernia,
in which the stomach
passes, partly or completely, into the chest cavity through the hole
("hernia") for the oesophagus
(which is also known colloquially as the "windpipe" or "gullet").
Medical complications of hernias may include:
- Cannot return the tissues of the hernia to their
usual state (irreducible).
Tissues of the hernia become swollen and fixed
within their sac (incarcerated).
Hearnia becomes cut-off from blood supply, becoming
painful and eventually gangrenous (strangulated).
The usual medical treatment for hernias (especially
painful ones) is surgical repair.
