What is a hernia?
A hernia is the protrusion of an organ (eg. small intestine, colon, bladder, visceral fat ) through a weakness in the abdominal wall.
A hernia occurs when the inner layers of the abdominal wall tear or weaken. This area of weakening enlarges as a result of excessive strain on the abdominal wall from heavy lifting, excessive weight gain, persistent cough or chronic constipation.
