An umbilical hernia is
a hernia that happens when part of the intestines bulges through the abdominal wall
next to the belly button.
More to Know
A hernia is an opening or weakness in the wall of a muscle,
tissue, or membrane that normally holds an organ in place. If the opening or weakness
is large enough, a portion of the organ may be able to poke through the hole. With
an umbilical hernia, the opening is found near the belly button, at a part of the
abdominal wall called the umbilical ring.
The umbilical ring is a muscle that surrounds the belly button. During pregnancy,
the umbilical cord flows through the umbilical ring to deliver blood and nutrients
to the developing baby. The umbilical ring normally closes shortly after birth. If
the muscle doesn't close correctly, the intestines can poke through. This can cause
a bulge near the belly button, especially when someone cries, coughs, or strains.
Umbilical hernias are most common in newborns
and infants under 6 months, but they can also affect older kids and adults. They usually
heal on their own by the time a baby is 1 year old. Surgery is only necessary if the
hernia is very large; grows in size after age 1 or 2; fails to heal by age 4 or 5;
or if blood flow to the part of the intestine sticking out gets cut off.
Keep in Mind
In most instances, an umbilical hernia causes no pain or problems and usually closes
up on its own by age 2. Surgery is rarely necessary and long-term complications are
rare, but any suspected hernia should be examined by a doctor.
