Hernia

How common are hernias?

Hernias are common in both adults and children. Men are much more likely to get them than women.

Researchers think that about 4.5 million people have an inguinal hernia (a hernia in the groin) at any one time.

⁵ Some babies, especially boys, are born with a weakness in the muscles in their abdomen. This can lead to a hernia, usually before the child is 1 year old. About 1 in 50 boys get a hernia. It's more common in babies born too early.
