What is Umbilical hernia?
Congenital umbilical hernia is a congenital malformation of the navel (umbilicus). Among adults, it is three times more common in women than in men; among children, the ratio is roughly equal. It is also found to be more common in children of African descent. An acquired umbilical hernia directly results from increased intra-abdominal pressure caused by obesity, heavy lifting, a long history of coughing, or multiple pregnancies.
