It is the protrusion of a segment of the intestine outside the abdomen. It acquires the adjective "uncomplicated" because there is no compromise of the protruded loop; it enters and exits easily through the hernial orifice without injuring the intestine.
There are hereditary causes (congenital abdominal wall disorder) and other acquired causes (abdominal trauma). Its appearance is favored by obesity, intense physical exercise and chronic constipation.
It manifests as a lump appearing on the abdominal wall. It characteristically increases in size when standing up, straining to defecate and with coughing.
The diagnosis is clinical by interrogation and physical examination where a lump appearing in the abdominal wall is evidenced.
As it is an uncomplicated hernia without compromised blood supply to the intestine, it does not require urgent treatment. The definitive treatment is surgical repair of the abdominal wall.
