Umbilical hernia
An umbilical hernia is very common in children. It appears as a small soft lump near the umbilicus (navel or belly-button). It usually causes no problems and goes away as the child grows.
- A hernia is the lump that appears when part of the body pushes through an opening or weak spot in a muscle wall.
- This happens most often around the abdomen (tummy area):
- an inguinal hernia (in the groin)
- a hiatus hernia (where part of the stomach pushes up through the diaphragm into the chest area),
- an umbilical hernia.
- An umbilical hernia happens when the muscles around the umbilicus (belly button) have a gap between them, so that part of the gut or other tissue in the abdomen can poke through particularly when pressure in the tummy rises (such as when a child cries or coughs). This can be pushed easily back into the tummy, but it does not matter if some usually stays pushed through the hernia.
Problems from an umbilical hernia
- Umbilical hernias in babies very rarely cause problems and are best left alone.
- The main problem with an umbilical hernia is the appearance of a bulge or lump. Young children do not have any discomfort and are not worried by the appearance, but many parents would prefer that the bulge was not there.
- Some hernias - but not umbilical ones - can cause problems when part of the bowel gets caught in the hernia. Inguinal hernias are usually operated on as soon as they are found, because it is quite common for bowel to get trapped in them.
What treatment is needed?
- If a baby has an umbilical hernia, nothing needs to be done, as almost will close by themselves.
- As children get older and their tummy wall muscles get stronger, the gap will usually close, and the bulge goes away. While this often happens before the age of one, it may not happen until the child is four or five years old.
- If it does not close by itself, the gap can be closed by an operation if the appearance causes distress to children when they begin to be self aware (usually not until they are around 6 years or older). The operation is simple and quick, and usually the child will not need to stay in hospital for more than a few hours. But still it is usually recommended that it is done when the child is old enough to be able to understand what is happening, and when an anaesthetic can be given very safely (when the child is at least 4 years old).
- If the umbilical hernia does cause problems (it becomes painful and it cannot be gently pushed back into the tummy), the child needs to be checked urgently by a doctor. This is rare.
Treatment that does not work for umbilical hernia
In the past some people recommended strapping the tummy or placing a coin on the hernia and then putting on strapping. These seemed to work, because the hernia did eventually go away, but it has been shown by research that the gap which causes the hernia will close just as quickly without strapping.
