A hernia occurs when an internal organ or fatty tissue pushes through a weakness in the surrounding muscle or connective tissue wall. While the concept sounds straightforward, hernias vary significantly in type, location, severity, and treatment -and understanding these differences is the first step toward getting the right care.
Dr. Deepak Subramanian, a hernia surgeon, sees patients across the full spectrum of hernia conditions. This guide covers every major hernia type in plain, patient-friendly language -with clear explanations of where each occurs, who is most at risk, and when to seek medical attention.
Why Hernia Type Matters
Not all hernias are treated the same way. A hernia’s location determines which structures are at risk, which surgical technique is most appropriate, and how urgently treatment is needed. Misidentifying a hernia type -or ignoring one entirely -can lead to serious complications, including incarceration (when herniated tissue becomes trapped and cannot be pushed back) or strangulation (when blood supply to the trapped tissue is cut off, requiring emergency surgery).
Identifying your hernia type accurately is therefore not an academic exercise -it directly shapes your treatment plan and outcome.
1. Inguinal Hernia -The Most Common Type
Inguinal hernia (groin hernia) is the most frequently diagnosed hernia worldwide, accounting for approximately 70–75% of all abdominal wall hernias. It occurs when a portion of the small intestine or abdominal fat pushes through a weakness in the inguinal canal (a passage in the lower abdominal wall through which blood vessels and, in men, the spermatic cord pass).
Inguinal hernias are significantly more common in men due to anatomical differences in the inguinal canal. They typically present as a visible or palpable (touchable) bulge in the groin, which may enlarge when standing, coughing, or straining.
Two subtypes exist: direct inguinal hernias (which push straight through a weak point in the abdominal wall) and indirect inguinal hernias (which follow the path of the inguinal canal). The distinction influences surgical planning.
2. Femoral Hernia -More Common in Women
Femoral hernia occurs when abdominal tissue or a section of intestine protrudes through the femoral canal (a small space beneath the inguinal ligament, just below the groin crease, through which blood vessels pass to the leg). The result is a bulge in the upper inner thigh or groin.
While less common than inguinal hernia overall, femoral hernia disproportionately affects women -particularly those who have had multiple pregnancies. Femoral hernias carry a higher risk of strangulation than inguinal hernias and should be evaluated promptly even when symptoms are mild.
3. Umbilical Hernia – Common in Infants and Adults
Umbilical hernia develops when abdominal tissue or a loop of intestine pushes through a weakness near the navel (belly button). The navel is a natural anatomical weak point -the site where the umbilical cord was attached during fetal development.
In infants, small umbilical hernias are common and frequently resolve on their own by age 2. In adults, umbilical hernias do not self-resolve and typically require surgical repair. Women who have had multiple pregnancies, individuals with obesity, and those with chronic increased abdominal pressure (from persistent cough or ascites -fluid accumulation in the abdomen) are at elevated risk.
4. Incisional Hernia -A Complication of Previous Surgery
An incisional hernia forms at the site of a prior abdominal surgical incision (cut), where the healing tissue creates a relative weakness in the abdominal wall. Intestine or abdominal fat can push through this weakened area, producing a bulge near the old scar.
Incisional hernias carry one of the highest recurrence rates of any hernia type -approximately 27.7% -making technique selection and mesh use particularly critical during repair. Risk factors include obesity, wound infection following the original surgery, and early return to strenuous activity before the incision has fully healed.
5. Epigastric Hernia -Between the Navel and Breastbone
Epigastric hernia occurs when fatty tissue protrudes through a weakness in the epigastric region -the midline of the upper abdomen, between the navel and the breastbone (sternum). Unlike most other hernia types, epigastric hernias rarely contain the intestine; they typically involve only fatty tissue called the omentum (the apron-like layer of fat covering the abdominal organs).
They are most common in adults between 20 and 50 years of age and are more frequent in men. Though often small, epigastric hernias can cause localised pain and tenderness -particularly after eating -and do not resolve without surgical repair.
6. Congenital Diaphragmatic Hernia -Present from Birth
Congenital diaphragmatic hernia (CDH) is a birth defect in which the diaphragm (the dome-shaped muscle separating the chest from the abdomen) fails to develop completely. The resulting opening allows abdominal organs -including the stomach, intestines, or liver -to migrate into the chest cavity during fetal development, where they compress the developing lungs.
CDH occurs in approximately 1 in 2,500 live births and is one of the more serious congenital conditions, as it can cause pulmonary hypoplasia (underdeveloped lungs) and respiratory failure at birth. It requires immediate neonatal management and surgical repair.
7. Spigelian Hernia -Rare and Often Misdiagnosed
Spigelian hernia occurs along the spigelian fascia -a band of fibrous tissue running vertically along the lateral edge (outer side) of the rectus abdominis muscle (the central front abdominal muscle). Because spigelian hernias develop between muscle layers rather than directly beneath the skin, they are frequently invisible on surface examination -making them one of the most commonly misdiagnosed hernia types.
Patients typically report localised abdominal pain without a visible bulge, which leads to delayed diagnosis. Ultrasound or CT imaging (a detailed cross-sectional scan) is often required to confirm the diagnosis. Despite their rarity, spigelian hernias carry a meaningful risk of incarceration and warrant surgical repair once identified.
8. Sports Hernia -Not a True Hernia, But Equally Serious
Despite its name, a sports hernia (also called athletic pubalgia -chronic groin pain caused by soft tissue injury in athletes) is not a hernia in the traditional anatomical sense. It refers to a tear or strain of the muscles, tendons, or ligaments in the lower abdomen or groin, caused by repetitive high-intensity movements involving twisting, cutting, or sudden directional changes.
Sports hernias are most frequently seen in footballers, hockey players, and athletes in contact sports. They do not produce a visible bulge but cause chronic groin pain that worsens with athletic activity. Treatment ranges from structured physiotherapy to surgical repair, depending on severity and response to conservative management.
9. Recurrent Hernia -When a Hernia Returns After Surgery
Recurrent hernia develops at or near the site of a previously repaired hernia. It is not a distinct anatomical hernia type but a classification based on surgical history -and it represents one of the most technically challenging scenarios in hernia surgery.
Recurrence rates vary by hernia type and repair method. Smoking, obesity, uncontrolled diabetes, and non-mesh repair techniques all elevate this risk. Recurrent hernias are generally more complex to repair than primary (first-time) hernias due to scar tissue from the previous operation, and they typically require specialist expertise and mesh reinforcement.
When Any Hernia Becomes an Emergency
Regardless of hernia type, certain symptoms signal a surgical emergency that requires immediate hospital attendance -do not wait for a scheduled appointment if you experience:
- A hernia bulge that suddenly becomes hard, tender, or impossible to push back
- Severe, worsening pain at the hernia site
- Nausea, vomiting, or inability to pass stool alongside hernia pain
- Skin over the hernia turning red, purple, or dark
- Fever accompanying localised hernia symptoms
These signs suggest incarceration or strangulation -both require urgent surgical intervention. According to the National Health Service (NHS), strangulated hernias are life-threatening if not treated promptly.
How Are Hernias Diagnosed and Treated?
Most hernias are diagnosed through clinical examination – a physical assessment by a specialist who evaluates the size, location, and reducibility (whether the hernia can be gently pushed back) of the bulge. Imaging studies such as ultrasound or CT scan are used for hernias difficult to identify on examination alone.
Treatment depends on hernia type, size, and symptom severity. Options range from watchful waiting for small, asymptomatic hernias to laparoscopic (keyhole), robotic, or open surgical repair for symptomatic or complicated cases. According to the European Hernia Society, mesh-based repair significantly reduces recurrence rates across most hernia types compared to non-mesh techniques.

The Right Diagnosis Starts With the Right Specialist
Each hernia type has a distinct anatomy, risk profile, and optimal treatment approach. A general surgical opinion is not always sufficient – particularly for complex, recurrent, or rare hernias that require specialist experience to both diagnose and repair correctly.
Dr. Deepak Subramanian at Chennai Hernia Care provides specialist evaluation across all hernia types, with access to laparoscopic and robotic surgical techniques tailored to each patient’s specific condition.

Frequently Asked Questions (FAQs)
Inguinal hernia is the most common, accounting for 70–75% of all abdominal wall hernias. It occurs in the groin and is significantly more prevalent in men due to anatomical differences in the inguinal canal.
All hernias carry risk if left untreated, but strangulated hernias -regardless of type -are the most immediately life-threatening. Femoral hernias strangulate more frequently than other types and are considered particularly high-risk even when small.
In infants, small umbilical hernias may close naturally by age two. In adults, hernias do not heal without surgical repair and typically worsen gradually as the defect enlarges under ongoing abdominal pressure.
Location provides the first clue -groin suggests inguinal or femoral, navel suggests umbilical, near an old scar suggests incisional. Accurate diagnosis requires examination by a hernia specialist, as some hernias like spigelian produce no visible bulge at all.
Inguinal hernias are far more common in men. Femoral hernias disproportionately affect women. Umbilical and incisional hernias affect both sexes, with additional risk in women following multiple pregnancies.
An untreated hernia typically enlarges, becomes increasingly painful, and carries a growing risk of incarceration or strangulation. Elective repair, when planned, is always safer and technically simpler than emergency repair.
