Inguinal Hernia
Introduction
An inguinal hernia is a common condition where tissue, such as part of the intestine, protrudes through a weak spot in the abdominal muscles. The bulging tissue can create a noticeable lump, often associated with discomfort or pain. Inguinal hernias are more common in men than women due to the natural weaknesses in the male groin area.
What is an Inguinal Hernia?
An inguinal hernia occurs when tissue pushes through a weak spot in the groin muscle, often appearing as a bulge on one or both sides of the pubic bone. This type of hernia is particularly noticeable during straining, coughing, or lifting heavy objects and may be more apparent when standing up.
Symptoms of Inguinal Hernia
- Visible Bulge: One of the most common signs, especially in the area around the pubic bone.
- Pain or Discomfort: May be felt in the groin area during activities that increase pressure in the abdomen, such as lifting, bending, or coughing.
- A Heavy or Dragging Sensation: Often described in the groin or scrotum.
- Weakness or Pressure in the Groin
- Occasional Pain and Swelling Around the Testicles: When protruding intestine descends into the scrotum.
Causes and Risk Factors
- Increased Pressure in the Abdomen: Caused by heavy lifting, constipation, or chronic coughing.
- A Pre-existing Weak Spot in the Abdominal Wall: Some people are born with a weaker abdominal wall, which can predispose them to hernias.
- Age: Tissues weaken as one ages.
- Pregnancy: Which can increase pressure inside the abdomen.
- Previous Hernia Repairs: Past surgery can lead to hernias due to weakened tissue at the site of the repair.
Diagnosing an Inguinal Hernia
Diagnosis typically involves a physical exam where the doctor may feel a bulge in your groin or scrotum while you stand and strain. If the diagnosis isn’t clear, imaging tests such as an abdominal ultrasound, CT scan, or MRI might be recommended to confirm the presence of a hernia.

Frequently Asked Questions
Inguinal hernias do not heal on their own. Surgery is the only definitive treatment to repair the hernia, although smaller, asymptomatic hernias may be managed conservatively if they do not cause discomfort or risk complications.
The most noticeable symptom of an inguinal hernia is a bulge on one or both sides of the pubic bone which becomes more apparent when upright, straining, or coughing. Pain or discomfort may also be present, especially when bending over, coughing, or lifting. There may also be a sensation of heaviness or dragging in the groin area.
Yes, the most significant risk of an untreated inguinal hernia is strangulated, which occurs when the blood supply to the part of the intestine or other trapped tissue is cut off. This condition is life-threatening and requires emergency surgery.
Recovery times vary; patients who undergo laparoscopic surgery often return to light activities within a few days and fully recover within 3 to 6 weeks. Recovery from open surgery might take slightly longer, with full recovery taking up to 6 weeks.
Yes, inguinal hernia surgery is generally safe and complications are rare. However, as with any surgery, there are risks such as infection, pain, or recurrence of the hernia. Discussing these risks with your surgeon will help you understand the potential complications and how they are managed.
While not all inguinal hernias can be prevented, minimising strain on the abdominal muscles and maintaining a healthy weight can help reduce risk. Avoid heavy lifting, manage chronic coughs, and relieve constipation with a high-fibre diet to reduce the chances of developing a hernia.
Open hernia repair involves a single long incision over the hernia site through which the surgeon repairs a hernia. Laparoscopic surgery uses several small incisions and a camera to guide the surgery. Laparoscopic surgery generally offers a quicker recovery, less postoperative pain, and a shorter return to normal activities.
