Umbilical hernia

Also called Belly button hernia

An umbilical hernia is when part of the bowel or fatty tissue pushes through a weak spot in the tummy wall near the belly button, causing a soft lump. It is common in babies and usually closes by itself before the age of 4 or 5. In adults it can be caused by being overweight, pregnancy or straining, and does not go away by itself.

What it is

In children, surgery is usually only needed if the hernia has not closed by about age 4 or 5, or if it is large.

In adults, surgery to repair the weak spot is often recommended, because the hernia can get bigger or become trapped.

Common signs

  • A soft lump in or near the belly button
  • A lump that gets bigger when coughing, crying or straining
  • A lump that may go back in when lying down
  • Discomfort in adults, sometimes

How it is usually diagnosed

  • Examination
  • Sometimes an ultrasound scan
