Umbilical Hernia in Newborns: Symptoms, Treatment, and When to See a Doctor

An umbilical hernia in newborns causes a soft bulge at the belly button and affects nearly 1 in 5 babies. Most close on their own by age 4 to 5 without any treatment. Our experts break down the causes, symptoms, home-care dos and don'ts, and the warning signs that need urgent medical attention.

An umbilical hernia in newborns is a soft bulge at the belly button that forms when the muscle opening through which the umbilical cord once passed does not fully close after birth. It appears in roughly 10% to 20% of infants and is more common in premature babies and those with low birth weight. The bulge often becomes more visible when the baby cries, coughs, or strains, and flattens when the baby is calm and lying down. In most cases, the opening closes naturally as the abdominal muscles grow stronger, usually before the child turns five.

Why Does An Umbilical Hernia Happen in Babies?

Before birth, the umbilical cord passes through a small gap in the abdominal wall called the umbilical ring, carrying nutrients from mother to baby. This ring is meant to close on its own soon after birth.

When the muscles on either side do not join completely, a portion of intestine or fatty tissue can push through the gap, covered only by skin. This is what creates the bulge presenting as an umbilical hernia. It has no connection to how the doctor cuts or clamps the cord during delivery, and it is not caused by anything the mother did during pregnancy.

What Are the Symptoms Of Umbilical Hernia in Babies?

An umbilical hernia in babies has a few clear, consistent signs that parents can watch for:

  • A soft, round bulge at or near the navel, sometimes the size of a small berry or a lime
  • The bulge grows larger during crying, coughing, or bowel movements
  • It shrinks or disappears when the baby is relaxed or lying on their back
  • No pain, redness, or discomfort in most cases
  • A doctor can often gently push the bulge back in during examination
Umbilical hernias in infants are usually painless and do not interfere with feeding, sleep, or weight gain.

How Big Can an Umbilical Hernia Get in Babies?

Umbilical hernias vary widely in size. Some are as small as a pea, while others grow to the size of a plum or a small lime.

The size of the hernial opening, rather than the size of the bulge itself, is what matters most for predicting whether it will close on its own. Smaller openings tend to close earlier, often within the first one to two years. Openings larger than 1.5 cm measured at age two are less likely to close spontaneously and are more likely to need surgical repair.

Even larger openings, however, have been known to close naturally in some children. Size alone does not determine treatment. A paediatrician measures the opening at check-ups to track this over time, rather than judging by how large the bulge looks when the baby cries.

How Is Umbilical Hernia Diagnosed in Newborns?

A paediatrician can usually diagnose an umbilical hernia through a physical examination alone. During a routine check-up, the doctor observes the bulge and watches for moments when the baby naturally cries or strains, which makes the bulge more visible, then gently presses on it to check if it goes back in.

Imaging tests, such as an ultrasound, are rarely needed and used only when there is uncertainty about the diagnosis or a suspected complication.

Does Umbilical Hernia in Babies Need Treatment?

Most umbilical hernias in newborns do not need any treatment. Studies show more than 90% resolve on their own by the time a child is 4 to 5 years old, and many close within the first one to two years.

Paediatricians typically recommend a " wait and watch" approach, monitoring the hernia at regular vaccination or growth check-ups.

Surgery is considered only if the hernia is large, causes symptoms, or has not closed by age 4 to 5. The procedure is short, usually under an hour, performed under general anaesthesia, and has a quick recovery.

Home Remedies Parents Should Avoid

In many households, family or elders suggest taping a coin over the baby's navel or wrapping a tight cloth or belly binder around the tummy to "push the hernia in" faster. Paediatric surgery guidelines make it clear that these methods do not accelerate closure of the muscle gap. Coins and tape are not sterile and can trap moisture against the skin, leading to rashes, sores, or infection.

Tight binding can also restrict a baby's breathing and digestion. There is no home remedy, oil, or massage proven to close an umbilical hernia faster; the opening closes on its own as the baby's abdominal muscles mature.

When Should You See a Doctor For Umbilical Hernia in Babies?

Contact your paediatrician promptly, or seek emergency care, if you notice:

  • The bulge becomes hard, swollen, discoloured, or tender to touch
  • The baby cries persistently, seems to be in pain, or refuses feeds
  • Vomiting, fever, or a bulge that cannot be gently pushed back in
  • The hernia has not started shrinking by the time the child is 4 to 5 years old
These signs may point to an incarcerated or strangulated hernia, where the trapped tissue loses its blood supply. This is rare, with the risk of incarceration estimated at 0.07% to 0.3%in unrepaired cases, but it is a medical emergency requiring immediate surgery.

Most umbilical hernias in newborns are a normal part of a baby's early growth and resolve without any intervention. Regular paediatric check-ups rather than home remedies are the safest way to monitor one.
