An inguinal hernia is one of the most common surgical conditions encountered in general practice, affecting a significant proportion of the Australian population, particularly men over the age of 40. As a General Surgeon based in Northern Sydney, I regularly consult with patients who are uncertain about their symptoms, apprehensive about surgery, or simply seeking clarity on their treatment options. This article has been prepared to provide an authoritative overview of inguinal hernias, from their underlying causes through to modern surgical management.
What is a Groin Hernia?
A hernia occurs when a portion of tissue protrudes through a weakened area of the abdominal wall in the groin region. The tissue which herniates might be the fatty apron which sites above the intestines (omentum), the intestines or even part of the urinary bladder.
This weakness typically develops along the inguinal canal, a natural passageway present in both men and women, though the condition is considerably more prevalent in men due to anatomical differences associated with testicular descent during foetal development.
Types of Groin Hernia
There are three main types of groin hernia which can develop. All three might be present !
- Indirect inguinal hernias arise when tissue passes through the inguinal canal via a congenital opening, and are more common in younger patients.
- Direct inguinal hernias occur due to a weakness in the abdominal wall musculature, typically developing later in life as a result of age-related tissue degeneration.
- Femoral hernia: the tissue might protrude via the femoral canal, which is another passageway in the groin region connecting the abdomen and the upper thigh.
Diagnosis is usually established during clinical examination and imaging, however, the final findings are often obtained during surgical repair.

What Causes an Inguinal Hernia?
Risk Factors can be groups into two broad categories
1) those which increase intra-abdominal pressure and downward push
- chronic coughing, due to smoking or respiratory illness
- pregnancy
- abdominal obesity
- chronic constipation and straining
- heavy lifting
2) those which decrease native tissue strength
- increasing age
- genetic or familial predisposition
- smoking
- diabetes
- immunosuppressive conditions or medications
Recognising the Symptoms
Early recognition of an inguinal hernia allows for timely intervention and reduces the likelihood of complications. Patients should be alert to the following presentations:
Common Symptoms
- A noticeable bulge in the groin or scrotum, which may become more prominent when standing, coughing, or straining
- A sensation of heaviness, aching, or discomfort in the groin, particularly toward the end of the day
- Discomfort that intensifies with physical exertion, lifting, or prolonged standing
- A bulge that may reduce, or disappear, when lying down
Symptoms Requiring Urgent Attention
- Sudden, severe pain accompanied by a firm, non-reducible bulge
- Nausea, vomiting, or fever in association with groin swelling
- Discolouration of the overlying skin
The latter symptoms may indicate an incarcerated or strangulated hernia, a surgical emergency requiring immediate assessment.
It is also important to note that not all groin lumps and pain are due to Hernia. Careful assessment and selection for surgery is therefore required. My General Surgery page provides further information on the broader assessment of abdominal pain, should this be relevant to your presentation.
Why Timely Treatment Matters
Unlike some medical conditions, an inguinal hernia will not resolve on its own. In the absence of surgical correction, the hernia will typically enlarge over time and may increase the risk of incarceration, whereby the protruding tissue becomes trapped, or strangulation, whereby its blood supply is compromised. The latter constitutes a genuine surgical emergency. For this reason, patients presenting with a suspected hernia are generally advised to seek surgical consultation promptly, even in the absence of significant discomfort.
Diagnostic Approach
Diagnosis of an inguinal hernia is primarily clinical, established through a detailed history and physical examination. In select cases, particularly where the diagnosis is uncertain or the hernia is not easily palpable, imaging modalities such as ultrasound or CT scanning may be employed to confirm the diagnosis and assess for any associated complications. In complex cases, Dr George might also recommend MRI imaging.
Treatment Options
Non-Surgical Management
In select, minimally symptomatic cases, a period of watchful waiting may be appropriate, particularly in older or frail patients for whom surgical risk outweighs the benefit of repair. However, this approach is not suitable for the majority of patients, given the progressive nature of the condition.
Surgical Repair
Surgery remains the definitive treatment for inguinal hernia and is recommended for the majority of symptomatic patients. Two principal surgical approaches are available:
Open Hernia Repair
This traditional technique involves a single incision over the site of the hernia, through which the protruding tissue is repositioned and the abdominal wall is reinforced, typically with a surgical mesh. Open repair remains an excellent option for many patients, particularly those with larger or recurrent hernias.
Laparoscopic (Keyhole) Hernia Repair
This minimally invasive technique utilises several small incisions, through which a camera and specialised instruments are inserted to repair the hernia from within. Laparoscopic repair is often associated with reduced postoperative discomfort, a shorter recovery period, and a quicker return to normal activity, making it a preferred option for many suitable patients, including those with bilateral hernias.
Dr George frequently performs both types of surgical repair. The optimal approach depends on a range of factors, including hernia size and type, patient anatomy, prior surgical history, and individual patient preference. The options are discussed in detail during a consultation.
Recovery Following Hernia Repair
Recovery timelines vary according to the surgical technique employed and individual patient factors. In general, patients undergoing laparoscopic repair may return to light activity within one to two weeks, while those undergoing open repair may require a somewhat longer period of restricted activity. Patients are generally advised to avoid heavy lifting and strenuous exercise for four to six weeks following surgery to allow for adequate healing and to minimise the risk of recurrence.
When Should You See a Surgeon?
If you have identified a groin bulge, experience discomfort in the groin region, or have any concerns regarding a possible hernia, it is advisable to seek a professional surgical opinion without delay. Early assessment allows for appropriate planning and reduces the likelihood of emergency presentation.

Take the Next Step Toward Relief
Living with an untreated inguinal hernia can significantly affect your comfort, mobility, and quality of life. With appropriate surgical care, patients can expect an excellent outcome and a full return to their usual activities. If you are experiencing symptoms of an inguinal hernia, I invite you to schedule a consultation at my Northern Sydney clinic, where I provide personalised, expert assessment and a full range of modern surgical treatment options, from hernia repair to broader general surgical care.
