What Is an Inguinal Hernia?
An inguinal hernia occurs when tissue from inside the abdomen—most commonly fat or intestine—protrudes through a weak area in the groin.
Some patients notice a visible swelling. Others experience discomfort while standing, lifting, coughing, exercising, or working. Some have a feeling of pressure or heaviness. And some have almost no symptoms at all.
In many patients, the swelling disappears when lying down or can be gently pushed back into the abdomen. This is called a reducible hernia.
The important point is that an inguinal hernia does not heal spontaneously.
Symptoms may improve or worsen over time, but the anatomical defect itself does not simply disappear.
Does Every Inguinal Hernia Need Immediate Surgery?
No.
In selected adults—particularly men with an asymptomatic or only minimally symptomatic inguinal hernia—watchful waiting can be a reasonable option.
But watchful waiting should not be confused with ignoring the hernia.
It means that immediate surgery may not offer enough benefit to justify operating at that moment, while the patient remains under observation and understands which changes should prompt reassessment.
This distinction matters because many patients with little or no pain gradually become accustomed to living with the hernia.
The swelling becomes part of everyday life.
They adapt the way they stand, lift, work, exercise, or dress. As long as there is no major pain, they may begin to treat the hernia as something that no longer requires attention.
This is one reason we still encounter very large hernias in routine surgical practice despite modern access to elective hernia repair.
The absence of severe pain does not necessarily mean that the condition has remained clinically irrelevant.
When Does Surgery Become More Reasonable?
The decision moves more strongly toward repair when the hernia causes meaningful pain or discomfort, interferes with work or exercise, increases in size, becomes more difficult to reduce, or produces recurrent episodes of pain or trapping.
But even here, symptoms should not be interpreted in isolation.
A patient who performs heavy physical work may experience the same anatomical hernia very differently from someone whose daily life involves little physical strain.
A patient who can easily take time away from work after surgery faces a different practical situation from someone whose income depends on returning to manual labour as quickly as possible.
This is why the decision should be based on the patient, not simply the size of the defect.
The Socioeconomic Reality Matters
There is another issue that is rarely discussed enough in conversations about elective hernia surgery.
Many patients with inguinal hernias are manual workers.
They lift, carry, push, pull, climb, or perform physically demanding work for a living.
After surgery, we may carefully explain postoperative recommendations. We may advise a gradual return to activity and discuss wound care, pain control, warning signs, and follow-up.
But medical advice exists inside a social and economic reality.
A patient may understand every recommendation perfectly and still return to strenuous work earlier than advised because the alternative is losing income.
Some patients simply cannot afford several weeks away from work.
That does not mean they are “non-compliant” in the simplistic sense of refusing medical advice.
Sometimes they are making the only decision they feel they can make.
When discussing postoperative recovery, complications, chronic pain, or recurrence, I do not think these realities should be ignored.
Recurrence is multifactorial and cannot be attributed to one behaviour alone. But the ability to follow a postoperative plan, attend follow-up, modify activity, control weight, stop smoking, or obtain help when something goes wrong is clearly influenced by a patient’s living conditions.
So the question should not only be:
“Can we repair this hernia?”
It should also be:
“What will the patient’s life look like after we repair it?”
Obesity Is Part of the Picture
Another important issue is obesity.
Obesity has become one of the defining health problems of our era, yet many patients do not immediately connect body weight with abdominal wall disease.
Excess body weight can increase mechanical stress on the abdominal wall and can complicate both the disease itself and its surgical treatment.
It may influence technical difficulty, wound-related problems, recovery, and the long-term durability of abdominal wall repair.
This does not mean that every patient with obesity should lose weight before hernia surgery or that surgery should automatically be delayed.
Again, the decision has to be individualized.
But weight should be part of the conversation.
Treating the hernia while completely ignoring the patient’s broader abdominal wall risk factors makes little sense.
What About Very Large Hernias?
Despite advances in elective surgery, very large inguinal and inguinoscrotal hernias still appear in everyday practice.
Some have been present for years.
Patients may have gradually adapted to them.
They may have delayed medical care because of fear, financial concerns, work obligations, embarrassment, or because the hernia caused surprisingly little pain.
But a small reducible hernia and a giant hernia that has evolved over many years are not the same surgical problem.
As a hernia enlarges, the anatomy, technical difficulty, postoperative recovery, and potential complications may also change.
This is another reason why “it does not hurt” should not always be the end of the discussion.
When Is an Inguinal Hernia an Emergency?
The situation changes completely when a hernia becomes acutely painful and cannot be reduced.
An incarcerated hernia means that the hernia contents become trapped.
A strangulated hernia is more serious because the blood supply to the trapped tissue may be compromised.
Sudden severe groin pain, an irreducible swelling, increasing tenderness, vomiting, abdominal distension, inability to pass stool or gas, or changes in the colour of the skin over the hernia require urgent medical assessment.
A painful, irreducible hernia should not be approached like an ordinary elective outpatient problem.
What About Women?
Groin hernias in women require particular attention because femoral hernias are relatively more common in women and can sometimes be mistaken for inguinal hernias.
Femoral hernias also have a greater tendency to present with incarceration or strangulation.
For this reason, prolonged watchful waiting is generally less attractive in women with a confirmed groin hernia than it may be in a minimally symptomatic man.
The exact recommendation still depends on the patient and the clinical situation.
Open or Minimally Invasive Surgery?
Once the decision for repair has been made, another question follows:
How should the hernia be repaired?
Broadly, inguinal hernia repair can be performed using an open approach or a minimally invasive approach, most commonly laparoscopic techniques such as TEP or TAPP.
Both can provide excellent results when appropriately selected and properly performed.
However, one problem I still encounter is that both some patients and some surgeons underestimate the potential advantages of minimally invasive hernia surgery.
There may be a tendency to regard open surgery as the more familiar, simpler, or more “proven” option simply because it has been practiced for longer.
But familiarity and superiority are not the same thing.
In appropriately selected patients and experienced hands, minimally invasive approaches can offer meaningful advantages, particularly in situations such as bilateral hernias, recurrent hernias after previous open repair, and patients in whom postoperative recovery and return to activity are particularly important.
At the same time, minimally invasive surgery is not automatically the correct answer for every patient.
The surgeon’s experience matters.
The patient’s previous operations matter.
The anatomy matters.
The available equipment and operating room environment matter.
The right question is therefore not:
“Is laparoscopic surgery better than open surgery?”
It is:
“Which approach provides the best balance of safety, recovery, and durability for this particular patient?”
Surgery Has Risks Too
Hernia surgery is common, but “common” does not mean risk-free.
Bleeding, infection, seroma, urinary retention, injury to surrounding structures, postoperative pain, chronic groin pain, and recurrence are all possible.
Serious complications are uncommon, but they are part of the decision.
This is why finding a hernia is not, by itself, enough to justify surgery.
The expected benefit of repair should outweigh the expected risks.
Asymptomatic Hernias: The Decision Is Becoming Clearer, but the Patient Still Matters
The boundaries of surgery for asymptomatic and minimally symptomatic inguinal hernias have become better defined.
We have increasingly useful evidence about when watchful waiting is reasonable and when elective repair should be considered more strongly.
But evidence cannot describe every patient’s life.
Two patients with an apparently identical asymptomatic hernia may live in completely different circumstances.
One may have a desk job, easy access to healthcare, stable income, and the ability to return rapidly for reassessment if symptoms change.
Another may perform heavy manual labour every day, live far from surgical care, have limited financial flexibility, and be unable to stop working when symptoms worsen.
The anatomical hernia may be similar.
The practical risk is not necessarily the same.
This does not mean that socioeconomic status should determine whether someone receives surgery.
It means that socioeconomic circumstances and lifestyle should be part of individualized surgical decision-making rather than treated as irrelevant background information.
Treat the Patient, Not the Hernia
This is perhaps the most important point.
A surgeon does not operate on a CT scan.
We do not operate on a centimetre measurement.
We do not operate on a bulge.
We operate on a person who happens to have a hernia.
That person has a job, a family, a body weight, other diseases, expectations, fears, economic limitations, physical demands, health literacy, and an individual tolerance for risk.
All of these matter.
Two patients with essentially the same inguinal hernia can reasonably receive different recommendations.
And that is not inconsistency.
That is individualized care.
So, When Should an Inguinal Hernia Be Operated On?
Surgery becomes increasingly reasonable when the hernia causes meaningful symptoms, limits daily life, enlarges, becomes difficult to reduce, or creates a clinically important risk of complication.
Emergency assessment is required when the hernia becomes acutely painful and irreducible or when symptoms suggest bowel obstruction or strangulation.
For selected adults with minimal or no symptoms, careful observation remains a valid option.
But the decision should extend beyond the hernia itself.
The patient’s occupation, body weight, general health, ability to attend follow-up, capacity to comply with postoperative recommendations, access to medical care, social support, and economic circumstances may all influence what constitutes the most sensible timing and approach.
A good hernia consultation should therefore not end with:
“You have a hernia, so you need an operation.”
It should answer a more useful question:
“For this patient, with this hernia, living this life, what is the right treatment and when is the right time to provide it?”

A groin swelling or suspected hernia should be assessed by an appropriate healthcare professional. Sudden severe pain, an irreducible swelling, vomiting, or other acute symptoms require urgent medical evaluation.
