Umbilical Hernia


An umbilical hernia is an abnormal bulge near an infant’s belly button, which occurs at the umbilical opening. The umbilical opening is a small opening in the abdominal muscles of the baby, through which the umbilical cord passes. This opening closes normally after birth. 

However, sometimes the muscles fail to come together forming an opening called an umbilical ring. When a part of the abdominal lining, intestine or abdominal fluid protrudes through the umbilical ring in the wall of the abdominal muscles, a protruding bulge, called an umbilical hernia, can be seen. In many cases, umbilical hernia subsides on their own as the umbilical opening closes over time.

In some cases, the protruding tissue may become trapped (incarcerated), leading to a more complicated disorder called the incarcerated umbilical hernia. This occurs because blood supply to the trapped part of the intestine is reduced, which could ultimately lead to tissue damage and further complications.   

Umbilical hernia is more common in children born with low birth weights, or those born prematurely. It is also equally common in girls and boys, and the size of the umbilical hernias also varies. ​

​The most noticeable symptom of an umbilical hernia is a bulge at your child’s belly button. This bulge becomes harder and larger when a baby cries, coughs or strains, as increasing abdominal pressure forces out the contents of the hernia. When the baby is relaxed, the hernia becomes soft again and may return back inside. 

Generally, umbilical hernia is not accompanied by any pain, though it may become painful if the intestines get trapped within the umbilical hernia, a more serious condition known as an incarcerated hernia. ​

Since it can be disturbing for parents to see a prominent bulge at their baby’s belly button, you must consult a paediatrician to discuss your concerns if you suspect your child has umbilical hernia. 

​In case the umbilical hernia appears discoloured with your baby being evidently in pain, or it is tender to touch or your baby vomits, you must seek immediate medical attention as these could be signs of an incarcerated umbilical hernia.

Consult a paediatrician working at the Children’s Hospital Service Line of The Aga Khan University Hospital to gain professional medical advice, discuss your child’s symptoms and receive personalized treatment and care.

​Your time with your doctor may be limited, so make sure to prepare for your visit beforehand. Here are some tips to help get you started.

​Your child’s doctor will first ask questions about any other symptom, such as pain, that you may have observed in your child. Thereby a detailed physical examination by a paediatrician will help make a diagnosis of umbilical hernia.

In some cases, a CT (Computerized Tomography) scan or abdominal ultrasound may be requested to check for the possibility of any complications associated with umbilical hernia.

In most cases, umbilical hernia closes themselves by the time a child is two or three years of age. That’s why surgery is not recommended immediately and a wait-and-see approach is prescribed to parents of children with umbilical hernia. 

However, surgery may be recommended to treat umbilical hernia if:

  • The hernia doesn’t go back into the abdomen by two or three years of age

  • The hernia is very large (if it’s more than half an inch in diameter)

  • The hernia is painful

  • The child has incarcerated umbilical hernia with trapped intestines

Surgery helps to place the protruding abdominal lining or intestine back in place and close the abdominal muscle opening to prevent a recurrence of the hernia. 

As with all surgical procedures, talk with your doctor at The Aga Khan University Hospital about the possible risks and complications of surgery before you try it.
