Finding out your child has a hernia, whether it was spotted during a routine check-up, noticed during a nappy change, or flagged after your child complained of groin discomfort, raises immediate and understandable concerns. Is it serious? Does it need surgery? Can it wait?
This guide answers those questions directly. Dr. Deepak Subramanian at Chennai Hernia Care regularly consults with parents of children diagnosed with hernias across all age groups from premature newborns to teenagers. Understanding what causes hernias in children, how they present differently from adult hernias, and what treatment options are available helps parents make informed decisions alongside their child’s medical team.
Why Do Children Get Hernias?
Hernias in children are almost always congenital (present from birth or arising from an incomplete developmental process that occurs before or shortly after birth), which is fundamentally different from most adult hernias, which develop over time due to lifestyle and mechanical factors.
Incomplete Closure of the Processus Vaginalis
The most common cause of inguinal hernia in children is a patent (open) processus vaginalis, a thin pouch of the abdominal lining that guides the testicles downward into the scrotum during fetal development. In most male infants, this pouch closes completely shortly before or after birth. When it remains open, it creates a direct pathway through which abdominal contents, typically a loop of intestine or fatty tissue, can push into the groin or scrotum.
This explains why inguinal hernia is significantly more common in boys than girls, occurring 3 to 10 times more frequently in males, and why premature infants face a dramatically elevated risk, since the processus vaginalis is more likely to remain open in babies born before the developmental closure process is complete.
Incomplete Closure of the Umbilical Ring
Umbilical hernia in children occurs when the umbilical ring (the opening through which the umbilical cord passed during fetal development) does not close completely after birth. The result is a soft, visible bulge at the navel that becomes more prominent when the baby cries, strains, or coughs.
Small umbilical hernias are extremely common in newborns, affecting up to 20% of infants, and the majority close spontaneously (on their own) by age two to four without any intervention. This makes umbilical hernia in infants a condition that is monitored rather than immediately treated in most cases.
Prematurity and Low Birth Weight
Premature infants face a substantially higher risk of hernia development because the normal developmental processes that close natural openings in the abdominal wall require the full gestational period to complete. Inguinal hernia incidence approaches 30% in very premature infants compared to approximately 1–3% in full-term babies, making hernia screening a routine component of premature infant care.
Genetic and Family History Factors
Children with a first-degree relative (parent or sibling) who had a hernia in childhood have a measurably higher risk of developing one themselves. Certain genetic connective tissue conditions, including Ehlers-Danlos syndrome (a group of inherited disorders affecting the strength and elasticity of connective tissue) are associated with elevated hernia risk across multiple anatomical sites.

Types of Hernia Most Common in Children
Inguinal Hernia
Inguinal hernia is the most common hernia requiring surgery in children, accounting for the majority of paediatric hernia operations. It appears as a bulge in the groin or in boys, sometimes extending into the scrotum that becomes visible when the child cries, coughs, or strains and may partially or completely disappear when the child is relaxed or lying down.
In girls, the ovary or fallopian tube can occasionally herniate through the inguinal canal a situation that requires prompt surgical attention because of the risk of vascular compromise (loss of blood supply) to the ovarian tissue.
Umbilical Hernia
Umbilical hernia presents as a soft, round protrusion at the navel. In infants, it is typically painless and reducible (can be gently pushed back). As noted above, the majority of small umbilical hernias resolve spontaneously in early childhood. Those that persist beyond age four to five, are larger than 1.5 cm, or are symptomatic are referred for surgical repair.
Incisional Hernia
While less common in children than adults, incisional hernia (a hernia developing at the site of a prior surgical scar) can occur following abdominal operations in the paediatric age group, particularly if the wound experienced infection or the fascial closure (the stitching of the deep muscle layer) was compromised during healing.

Symptoms of Hernia in Children: What Parents Should Watch For
Visible Bulge
The most reliable sign of hernia in a child is a visible or palpable (touchable) bulge in the groin, scrotum (in boys), labia (in girls), or at the navel. The bulge typically becomes more prominent during crying, coughing, straining during bowel movements, or physical activity and may reduce or disappear when the child is calm and lying flat.
Parents often first notice the bulge during bathing, nappy changing, or dressing. Any new, unexplained bulge in these locations in a child warrants prompt medical review even if it comes and goes.
Pain and Irritability
Older children may report pain or discomfort in the groin or abdomen, particularly during physical activity. In infants and younger children who cannot verbalise discomfort, unexplained irritability, especially during nappy changes or when the groin area is touched, is a common indicator that the hernia is causing discomfort.
Feeding Difficulties and Vomiting
In infants with inguinal hernia, episodes of vomiting, refusal to feed, or abdominal distension (bloating) alongside a firm, tender groin bulge may indicate that the hernia has become incarcerated (the herniated tissue cannot be pushed back). This requires urgent medical attention.
Emergency Symptoms: Act Immediately
Certain symptoms indicate a strangulated hernia (where the blood supply to the trapped herniated tissue has been cut off, a surgical emergency in any age group):
- A hernia bulge that suddenly becomes hard, very tender, and cannot be reduced
- Skin over the bulge turning red, purple, or darkened
- The child becomes acutely unwell, pale, distressed, vomiting
- Fever alongside a tense, painful groin or abdominal bulge
Strangulated hernias in children require immediate hospital attendance do not wait for a scheduled appointment. According to the Royal College of Surgeons of England, the risk of incarceration is highest in the first year of life, making early surgical repair particularly important for infants with inguinal hernia.

When Does a Child’s Hernia Need Surgery?
Inguinal Hernia Surgery Is Always Recommended
Unlike an umbilical hernia, an inguinal hernia in children does not resolve spontaneously. Surgical repair is always recommended once the diagnosis is confirmed; the only question is timing. Because the risk of incarceration is highest in infancy (particularly in the first six months of life), early repair is generally advised as soon as the infant is medically stable enough to safely undergo anaesthesia.
For premature infants, surgery is typically planned shortly before or around the time of hospital discharge from the neonatal unit, balancing the risk of anaesthesia in a small infant against the risk of hernia complications if repair is delayed.
Umbilical Hernia Watchful Waiting First
Small umbilical hernias in children under four years of age are managed with watchful waiting and regular monitoring to track whether the hernia is closing spontaneously, as the majority will. Surgical repair is considered when the hernia persists beyond age four to five, the defect is larger than 1.5 cm, the hernia is symptomatic, or any sign of incarceration develops.
The traditional practice of taping coins over umbilical hernias to encourage closure is not medically recommended; it does not accelerate natural closure and can cause skin irritation.
Contralateral Exploration
During inguinal hernia repair in infants and young children, some surgeons assess the opposite (unaffected) side for a patent processus vaginalis, since bilateral (both-sided) inguinal hernia is present in a meaningful proportion of children estimated at 10–30% depending on age and gestational history. The decision to explore the opposite side is made individually based on the child’s age, prematurity history, and intraoperative findings.
Hernia Surgery in Children: What the Procedure Involves
Surgical Approach
Laparoscopic (keyhole) repair is increasingly used for paediatric inguinal hernia repair, offering smaller incisions, excellent visualisation of the anatomy, and the ability to assess the contralateral side during the same procedure. Incisions are typically less than 1 cm, and procedure time averages 20–40 minutes in experienced hands.
Open herniotomy (the traditional open surgical technique involving a small groin incision, identification of the hernia sac, and high ligation tying off the sac at its base without the need for mesh in most paediatric cases) remains the gold standard for many paediatric presentations and continues to produce excellent outcomes.
A key distinction from adult hernia repair: mesh is not routinely used in paediatric inguinal hernia repair. In children, the underlying tissue is healthy and the hernia sac ligation alone without mesh reinforcement achieves excellent long-term results. Mesh use in children is reserved for selected cases with unusually large defects or other specific clinical indications.
According to the Journal of Pediatric Surgery, recurrence rates following paediatric inguinal hernia repair in experienced hands are below 1–3% significantly lower than adult recurrence rates reflecting both the clean tissue environment and the effectiveness of the herniotomy technique in this age group.
Anaesthesia
All paediatric hernia surgery is performed under general anaesthesia (medication that renders the child fully unconscious and pain-free). Anaesthetic safety in children has advanced significantly, and serious anaesthetic complications in healthy children are rare. Your surgical and anaesthetic team will explain the procedure, fasting requirements, and what to expect before and after in detail.

Recovery After Hernia Surgery in Children
Children recover from hernia surgery with remarkable speed compared to adults. Most children are discharged home the same day as their operation and resume normal behaviour within 24–48 hours.
Activity restrictions typically last two weeks, during which contact sports, rough play, swimming, and any activity that risks direct impact to the surgical site should be avoided. Most children return to school within one week and to full physical activity including sports by three to four weeks post-operatively.
Pain management in the immediate post-operative period uses weight-appropriate doses of paracetamol (acetaminophen) and in some cases ibuprofen, avoiding opioid medications wherever possible. Local anaesthetic infiltration at the incision site during surgery provides meaningful pain relief in the first several hours after the procedure.
Wound care is straightforward; the incisions are small, typically closed with dissolvable sutures (stitches that do not need removal) or surgical adhesive, and require only gentle cleaning and drying. Parents should watch for increasing redness, swelling, or discharge from the wound site and contact the surgical team if these develop.
Specialist Care for Your Child’s Hernia
A hernia diagnosis in a child is understandably worrying, but with the right surgical team and timely management, outcomes in paediatric hernia repair are consistently excellent. The key is early assessment, accurate diagnosis, and an experienced surgeon who works with children regularly.
At Chennai Hernia Care, Dr. Deepak Subramanian provides specialist evaluation for paediatric hernia cases, with access to both laparoscopic and open surgical techniques tailored to each child’s age, anatomy, and specific hernia presentation.
If you have noticed a bulge in your child’s groin or navel, or your child has been diagnosed with a hernia, do not delay seeking specialist assessment.

Frequently Asked Questions (FAQs)
Umbilical hernias in children under four years frequently resolve without surgery; the majority close naturally by age two to four. Inguinal hernias in children do not resolve without surgery and require repair once diagnosed to prevent the risk of incarceration or strangulation.
Yes. Paediatric hernia repair is one of the most commonly performed surgical procedures in children and carries an excellent safety record when performed by an experienced surgeon in an appropriate facility.
A hernia that becomes suddenly hard, very tender, irreducible, and is accompanied by a distressed, vomiting child or skin discolouration over the bulge is a surgical emergency. Go to the nearest emergency department immediately rather than waiting for an appointment.
In most paediatric inguinal hernia repairs, mesh is not required. The hernia sac ligation technique used in children produces excellent results without mesh, as the surrounding tissue is healthy and strong. Mesh is reserved for selected cases with unusually large defects.
Hernias in newborns are almost always caused by incomplete closure of natural anatomical openings during fetal development, specifically the processus vaginalis (for inguinal hernia) or the umbilical ring (for umbilical hernia). They are not caused by anything the mother did during pregnancy.
