An Umbilical Hernia is a common condition in newborns that occurs when the abdominal wall does not close completely after birth. During pregnancy, the Umbilical Cord passes through a small opening in the baby’s abdominal muscles. After birth, this opening usually closes on its own.
In some babies, however, the opening remains partially open, allowing tissues or parts of the intestine to bulge outward, creating a noticeable swelling around the belly button. This bulge often becomes more visible when the baby cries or strains.
Despite its worrying appearance, umbilical hernias are usually painless and harmless, and most cases close naturally before the child reaches four or five years old. Surgery is generally required only in more severe cases or when the opening does not close over time.
Causes of Umbilical Hernia in Infants
Several factors may contribute to the development of an umbilical hernia in babies:
Incomplete closure of abdominal muscles: The main cause is when the opening in the abdominal wall (where the umbilical cord passed during pregnancy) does not fully close after birth.
Weak abdominal wall: Structural weakness around the belly button allows internal tissues or intestines to push outward when pressure increases.
Premature birth: Babies born early often have underdeveloped abdominal muscles, increasing the likelihood of a hernia.
Genetic factors: Umbilical hernias occur more frequently in children with Down Syndrome or other chromosomal conditions such as Trisomy.
Rare medical conditions: Some connective tissue disorders like Ehlers-Danlos Syndrome and Beckwith-Wiedemann Syndrome may also be associated.
Hormonal disorders: In some cases, it may appear alongside Congenital Hypothyroidism.
Possible Complications
Complications from umbilical hernias are rare, but they can become serious if they occur. The most concerning complication is called incarcerated or strangulated hernia.
1. Trapped or Strangulated Intestine
This happens when part of the intestine becomes stuck in the opening and cannot move back into the abdomen. Blood flow may be cut off, which can lead to tissue death (gangrene) and requires emergency surgery.
2. Intestinal Blockage
If the intestine becomes trapped, food and waste may not pass through properly, leading to severe constipation.
3. Infection and Inflammation
When the intestine is displaced or food remains stuck, bacteria can grow more easily, increasing the risk of infection.
Symptoms of Umbilical Hernia in Babies
Parents can usually notice the signs easily. Common symptoms include:
Visible bulge around the belly button: A soft swelling typically measuring 1–5 cm in diameter.
Bulge appears with pressure: The swelling becomes more noticeable when the baby cries, coughs, laughs, or strains.
Easily pushed back inside: In normal cases, gentle pressure can push the bulge back into the abdomen without causing pain.
Normal skin color: The skin covering the hernia usually looks normal and not red or inflamed.
No pain: Most babies with umbilical hernias do not feel discomfort and remain active and healthy.
When Should You See a Doctor Immediately?
Although most umbilical hernias are harmless, seek urgent medical care if you notice any of the following warning signs:
The bulge becomes red, purple, or blue
The hernia becomes hard and cannot be pushed back in
Sudden increase in size
Severe or persistent crying due to abdominal pain
The baby becomes sensitive to touch around the belly
Persistent vomiting
Inability to pass gas or stool
Fever
These symptoms may indicate a strangulated hernia, which requires emergency medical attention.
Treatment of Umbilical Hernia in Babies
1. Observation and Monitoring
In most cases, doctors simply monitor the condition during routine checkups because many umbilical hernias close naturally by age 4–5.
2. Avoid Home Remedies
Traditional practices such as placing coins, tight bands, or adhesive tapes on the belly button should be avoided. These methods do not help the hernia close and may irritate the skin or trap the intestine.
3. Surgical Treatment
Surgery may be recommended if:
The hernia persists after age five
The opening is very large
Complications develop
4. Emergency Surgery
If the intestine becomes trapped or strangulated, immediate surgery is necessary. The procedure typically involves returning the tissues to their proper position and closing the abdominal opening with stitches.
✅ Important: In most babies, umbilical hernias resolve naturally without treatment. Parents should simply monitor the area and watch for any unusual changes while attending regular pediatric checkups.
