During pregnancy, the umbilical cord passes from the mother to the baby through a small opening in the baby’s abdomen. A weakness in the abdomen occurs when the muscles of the baby’s abdomen do not completely close after birth. The weakness can cause abdominal tissue to push through the belly button.
Umbilical hernias in infants are more common in African American infants. Risk factors for any infant include:
There are usually no symptoms associated with an umbilical hernia.
You will be asked about your baby's symptoms and medical history. A physical exam will be done.
An umbilical hernia can be diagnosed by a physical exam.
In most infants, an umbilical hernia will go away on its own as the baby develops. This is usually within the first few years of life.
Persistent small hernias that do not cause symptoms may not need treatment. You and your doctor will watch the hernia to make sure new problems do not develop.
Large hernias or those causing symptoms will require additional care. For example:
These conditions may require surgery to place dislocated tissue back in place and close damaged wall.
There are no current guidelines to prevent an umbilical hernia.
