What is a hernia?
A Hernia occurs when internal tissue or part of the bowel pushes through a weak area in the abdominal wall.
This weakness may be present from birth or develop over time due to:
- Heavy lifting
- Chronic coughing
- Previous surgery
- Age-related muscle weakening
Hernias do not heal on their own and may gradually increase in size or symptoms.
Symptoms of a Hernia
Common symptoms of a hernia include:
- Visible bulge in the abdomen or groin
- Pain or discomfort when lifting, coughing, or bending
- A dragging or heavy sensation
- Burning, aching, or pressure in the area
- Bulge that becomes more noticeable with standing or exertion
- In some cases, no symptoms at early stages
Types of Hernias
Inguinal Hernia
The most common type of hernia, occurring in the groin. More common in men.
Femoral Hernia
Occurs lower in the groin. More common in women and carries a higher risk of complications.
Umbilical and Para-umbilical Hernia
Occur at or near the belly button.
Ventral Hernia (including Incisional Hernia)
Develop through a previous surgical incision or weakened abdominal wall.
Treatment
When is Hernia Surgery Needed?
Hernia repair may be recommended if you experience:
- Pain, discomfort, or a noticeable bulge
- Limitation of daily activities or exercise
- Increasing hernia size over time
- Risk of incarceration or strangulation (hernia becoming trapped or losing blood supply)
- Femoral hernias (often repaired early due to higher risk of complications)
Surgery is the only definitive treatment for a hernia.
How Hernia Repair is Performed
Hernia repair is performed under general anaesthesia and involves reinforcing the weakened abdominal wall, often using surgical mesh.
The most appropriate technique depends on hernia type, size, location, previous surgery, and patient factors.
Keyhole (Laparoscopic) Hernia Repair
Small incisions are made in the abdomen, and a camera (laparoscope) is used to guide the repair.
The hernia is repaired from behind the abdominal wall, and mesh is placed in the extraperitoneal (pre-muscle) plane to reinforce the weakness.
Benefits:
- Less post-operative pain
- Faster recovery
- Smaller scars
- Earlier return to normal activities
This approach is commonly used for bilateral or recurrent hernias.
Open Hernia Repair
An incision is made directly over the hernia site. The surgeon repairs the defect and places mesh to strengthen the abdominal wall.
This approach may be preferred for:
- Large or complex hernias
- Recurrent hernias
- Incisional hernias
- Patients not suitable for laparoscopic surgery
Recovery After Hernia Surgery
Recovery varies depending on the type of hernia and surgical approach.
Typical recovery timeline:
- Most patients go home the same day or after an overnight stay
- Light activity can begin within a few days
- Desk-based work: 1–2 weeks
- Heavy lifting or physical work: 2–4 weeks (sometimes longer depending on case)
Patients are encouraged to gradually return to activity as guided by their surgeon.
Potential Risks and Complications
As with any surgery, there are risks involved. These may include:
- Bleeding or infection
- Recurrence of the hernia
- Chronic pain
- Mesh-related complications (rare)
- Injury to surrounding structures (rare)
These risks are carefully discussed during consultation and consent.
Frequently Asked Questions
How do they test for a hernia?
A hernia is usually diagnosed through a physical examination. In some cases, ultrasound or CT imaging may be used if the diagnosis is unclear.
Can a hernia go away without surgery?
No. Hernias do not heal on their own and may slowly worsen over time.
What happens if a hernia is left untreated?
It may increase in size and, in some cases, become trapped (incarcerated) or lose blood supply (strangulated), which is a medical emergency.
Is hernia surgery painful?
Most patients experience mild to moderate discomfort after surgery, which improves significantly within a few days.
How long is recovery after hernia surgery?
Most patients return to desk work within 1–2 weeks, while physical jobs may require 2–4 weeks of recovery.
Is mesh always used in hernia repair?
Mesh is commonly used because it reduces the risk of recurrence. In select cases, non-mesh repair may be considered.
How is the surgical approach decided?
The decision depends on hernia type, size, previous surgery, and patient health factors.
