A hernia is a weakness or opening in the abdominal wall, which often results in bulging out of fat or an organ such as intestine, which then occupies space under the skin. The opening in the abdominal wall through which the fat or organs protrude is called the Hernia defect. Hernia can affect anybody – going by statistics one-in-ten of us will have hernia at some point in our lives. It is found in both sexes, can occur at any age and sometimes infants may be born with it. Surgery for hernia is one of the most commonly performed operations worldwide with millions of cases being treated every year.
