Hernia Symptoms, Causes & Treatment | Specialist Hernia Surgeon Sydney
What is a Hernia?
A hernia is a common condition where internal tissue pushes through a weakness in the abdominal wall, often causing a visible lump or discomfort. While some hernias may initially be painless, many progress over time and require assessment by a specialist hernia surgeon. Early diagnosis allows appropriate planning of treatment, including hernia repair where indicated, and helps reduce the risk of complications or emergency surgery.
Hernia repair surgery is the only definitive treatment and is commonly performed using minimally invasive (keyhole) techniques. Hernias do not resolve on their own and may enlarge over time, particularly with physical strain or increased abdominal pressure.
The abdominal wall normally provides strength and support. When a defect develops in the muscle layer, the skin and fat above it stretch and allow tissue to protrude. Hernias most commonly occur at natural weak points in the abdominal wall, particularly in the groin region where inguinal hernias develop.
If you have been diagnosed with a hernia or are experiencing symptoms, specialist assessment can determine whether surgical repair is recommended.

Types of Hernias
Inguinal Hernia
The most common type of hernia, particularly in men. It occurs in the groin where the spermatic cord passes toward the testicle.
Femoral Hernia
Occurs just below the groin where major blood vessels pass into the thigh. More common in women.
Umbilical Hernia
Occurs around the belly button and may appear as a visible bulge. In adults, it is often associated with increased abdominal pressure.
incisional and ventral hernia
Develops at the site of previous abdominal surgery where scar tissue is weaker than surrounding muscle.
Epigastric Hernia (upper abdominal hernia)
Occurs between the breastbone and the belly button.
Spigelian Hernia
A less common hernia occurring along the outer edge of the abdominal muscles. It may be difficult to detect and sometimes requires imaging.
When should you see a hernia specialist?

What Causes Hernias?
Hernias often develop due to a combination of muscle weakness and increased abdominal pressure.
Common contributing factors include:
Heavy lifting
Chronic coughing
Constipation
Urinary straining
Obesity (learn more about obesity and bariatric treatment)
Male sex (for inguinal hernia)
Previous abdominal surgery
Pregnancy
Family history
In many cases, patients cannot identify exactly when the hernia first developed.
Symptoms of Hernia
Some hernias cause no symptoms and are discovered during examination. When symptoms occur, they may include:
A visible lump that increases when standing or straining
Discomfort, pressure, or dragging sensation
Groin pain (inguinal hernia)
Pain during lifting or coughing
A lump that comes and goes
Symptoms often worsen over time as the defect enlarges.
Can a hernia heal without surgery?
No. Hernias do not repair themselves and typically enlarge over time. While symptoms may fluctuate, the underlying defect remains and often requires surgical repair to prevent progression or complications.
Complications of Hernias
Hernias do not repair themselves and most often require hernia repair surgery. Over time hernias tend to get bigger as the defect in the muscle stretches to allow more abdominal contents to slip in and out. As they grow, the risk of complications increases.
Because hernias do not resolve on their own, most symptomatic cases are managed with planned surgical repair rather than observation.
Incarceration
The hernia contents become trapped and cannot be pushed back in. This may cause persistent discomfort.
Strangulation
The blood supply to the herniated tissue becomes compromised. This causes:
Severe pain
Swelling
Nausea or vomiting
Redness over the hernia
Inability to pass gas or stool
Strangulation is a surgical emergency and requires urgent hospital assessment.
Early evaluation by a specialist upper gastrointestinal surgeon allows planned repair and reduces the risk of emergency surgery.
Who Should Consider Hernia Repair?
Patients with symptomatic hernias are generally advised to undergo repair before complications occur.
Surgery may be recommended if:
The hernia causes pain
The bulge is enlarging
Daily activities are affected
There is risk of incarceration
The patient is medically fit for surgery
Patients with strangulated hernias require urgent surgery.

How Are Hernias Diagnosed?
Most hernias are diagnosed clinically during examination.
Imaging may be used when diagnosis is unclear:
Ultrasound
CT scan
MRI (in selected cases)
Pre-operative tests are performed based on age and medical history to ensure safety under anaesthesia.
Hernia FAQs
Can a hernia go away without surgery?
No. A hernia does not heal on its own and usually requires hernia repair surgery to prevent enlargement or complications. Early specialist assessment allows planned treatment rather than emergency surgery.
Is a hernia dangerous?
Most hernias are not immediately dangerous, but complications such as incarceration or strangulation can occur. Severe pain, nausea, vomiting or a firm irreducible lump require urgent hospital assessment.
When should I see a surgeon for a hernia in Sydney?
If you notice a persistent lump, groin discomfort, or abdominal pain, assessment by a specialist upper gastrointestinal surgeon in Sydney allows early diagnosis and discussion of repair options.
Can I exercise with a hernia?
Light activity may be possible, but heavy lifting or straining can worsen symptoms or enlarge the defect. A specialist can advise whether watchful waiting or hernia surgery is recommended.
Do all hernias require surgery?
Most symptomatic hernias are recommended for repair, as they do not resolve spontaneously. Surgical repair strengthens the abdominal wall and reduces the risk of complications.
