At Conrad Pearson Clinic, we often see concerned parents whose newborns have been diagnosed with a hernia. While the word hernia can sound alarming, it’s important to understand that this condition is relatively common in infants—especially those born prematurely—and that effective treatments are available.
What Is a Hernia in Infants?
A hernia occurs when a small portion of tissue—often part of the intestine—pushes through a weak spot in the abdominal wall or groin area. In babies, the two most common types are:
· Inguinal hernia: Appears in the groin or scrotum when the abdominal contents push through an opening that hasn’t fully closed.
· Umbilical hernia: Appears around the belly button when the muscle opening that allows the umbilical cord to pass through doesn’t close completely after birth.
Why Premature Infants Are More Susceptible
Premature infants—those born before 37 weeks of gestation—have not had as much time for their bodies to fully develop before birth. This immaturity affects many organ systems, including the muscles and connective tissues that help hold the abdominal organs in place.
Here are the top four reasons hernias are more common in premature infants:
1. Incomplete Closure of Natural Openings
During fetal development, certain natural openings in the abdominal wall, such as the inguinal canal, normally close before birth. In premature babies, these structures may still be open, allowing the intestine or other tissue to slip through and form a hernia.
2. Weaker Muscle and Tissue Support
The abdominal wall and connective tissues of premature infants are thinner and less developed. This makes it easier for internal organs to push through weak spots, especially when the baby cries, coughs, or strains.
3. Increased Abdominal Pressure
Premature infants often need breathing support, such as continuous positive airway pressure (CPAP) or mechanical ventilation. These therapies can increase pressure in the abdomen, which may contribute to the formation of hernias.
4. Higher Rates in Boys
Inguinal hernias occur more often in male infants—especially those born prematurely—because the testicles descend from the abdomen into the scrotum late in pregnancy. If this process happens early (before full closure of the inguinal canal), it can leave an opening that allows a hernia to develop.
How Are Infant Hernias Treated?
While some umbilical hernias may close on their own as a child grows, inguinal hernias do often require surgical repair. The good news is that pediatric hernia repair is a safe and routine procedure, typically performed as outpatient surgery. Prompt treatment helps prevent complications, such as the intestine becoming trapped (a condition called incarceration), which can be serious.
Supporting Families Through Care
At Conrad Pearson Clinic, our team understands that any surgery or diagnosis in a newborn can be stressful. We take time to explain each step, coordinate with pediatric specialists, and ensure your child receives the safest and most compassionate care possible. If your baby has been diagnosed with a hernia—or if you have concerns about a bulge or swelling in your infant’s groin—contact Dr. Gleason, our Pediatric Urologist, for an evaluation. Early diagnosis and treatment lead to the best outcomes for your child’s health and comfort.
