Hernia: Symptoms, Causes, Types, Treatment and Hernia Surgery
A small bulge in the abdomen or groin may seem harmless at first. But if that lump becomes painful, increases in size, or interferes with daily activities, it could be a sign of a hernia.
A hernia occurs when an internal organ or tissue pushes through a weakened area of the surrounding muscle or connective tissue. Hernias are common and can affect people of different ages. While some hernias may cause little or no discomfort initially, others may require surgical treatment to prevent complications.
Understanding the symptoms, types and treatment options can help you seek medical attention at the right time.
What Is a Hernia?
A hernia develops when tissue, such as part of the intestine or abdominal tissue, pushes through a weak spot in the abdominal wall or surrounding muscle.
One of the most noticeable signs is a bulge or lump that may become more prominent when you cough, sneeze, strain, lift something heavy or stand for a long time. In some cases, the bulge may become less noticeable when you lie down.
A hernia does not usually disappear permanently on its own. Whether treatment is required depends on factors such as the type of hernia, its size, symptoms and the patient's overall health.
What Causes a Hernia?
A hernia can develop because of a combination of muscle weakness and increased pressure inside the abdomen.
Common contributing factors include:
Weakness in the abdominal wall
Repeated heavy lifting or physical strain
Chronic coughing
Constipation and repeated straining during bowel movements
Being overweight or obese
Pregnancy
Previous abdominal surgery
Age-related weakening of tissues
Certain conditions that increase pressure within the abdomen
Not everyone with these risk factors will develop a hernia, but they can increase the likelihood.
Common Types of Hernia
Hernias can occur in different areas of the body. Some of the commonly encountered types include:
1. Inguinal Hernia
An inguinal hernia develops in the groin and is one of the most common types of abdominal wall hernia. It may appear as a swelling in the groin and can sometimes extend into the scrotum in men. Discomfort may become more noticeable while coughing, lifting or standing for prolonged periods.
2. Umbilical Hernia
An umbilical hernia develops around the belly button. It can occur in children as well as adults and may appear as a noticeable swelling near the navel.
3. Femoral Hernia
A femoral hernia occurs near the upper thigh or groin. Although less common than inguinal hernias, it can require prompt medical assessment because complications may occur.
4. Incisional Hernia
An incisional hernia can develop through or near a previous surgical incision in the abdominal wall. It may occur months or even years after abdominal surgery.
5. Hiatus Hernia
A hiatus hernia is different from abdominal wall hernias. It occurs when part of the stomach moves upward through an opening in the diaphragm. It may be associated with symptoms such as acid reflux and heartburn.
What Are the Symptoms of a Hernia?
The symptoms can vary depending on the type and size of the hernia.
Common signs include:
A visible or palpable lump in the abdomen or groin
Pain or discomfort around the swelling
A feeling of heaviness or pressure
Burning or aching in the affected area
Discomfort while coughing, lifting or straining
A swelling that becomes more prominent while standing
A bulge that may reduce when lying down
Some people may have very few symptoms despite having a hernia. This is why a new or unexplained abdominal or groin lump should be evaluated by a doctor.
When Can a Hernia Become an Emergency?
Although many hernias are not emergencies, a hernia can sometimes become incarcerated, meaning the protruding tissue becomes trapped and cannot be pushed back. If the blood supply to the trapped tissue is cut off, it is known as a strangulated hernia, which requires urgent medical treatment.
Seek immediate medical attention if a hernia is accompanied by:
Sudden or severe pain
A rapidly enlarging or very tender swelling
A lump that previously went back in but suddenly cannot be pushed back
Redness over the swelling
Abdominal bloating
Nausea or vomiting
Difficulty passing stool or gas
Fever
These symptoms should not be ignored.
How Is a Hernia Diagnosed?
A surgeon will generally begin with a detailed medical history and physical examination. The doctor may examine the swelling while you are standing, coughing or straining.
Depending on the location and clinical findings, additional tests such as an ultrasound or other imaging investigations may sometimes be recommended.
The objective is not only to confirm the presence of a hernia but also to understand its location, size and whether there are any associated complications.
Does Every Hernia Need Surgery?
Not every hernia requires immediate surgery.
The decision depends on factors such as:
Type of hernia
Size and location
Presence and severity of symptoms
Risk of complications
Previous hernia surgery
Age and general health
Impact on daily activities
For some minimally symptomatic inguinal hernias, a doctor may recommend observation in selected patients. However, symptomatic or complicated hernias may require surgical repair.
A consultation with a qualified surgeon can help determine the appropriate approach rather than relying on self-treatment or delaying evaluation.
What Is Hernia Surgery?
Hernia surgery involves returning the protruding tissue to its appropriate position and repairing the weakened area of the abdominal wall.
Depending on the individual case, the repair may be performed through open surgery or laparoscopic/keyhole surgery.
In many repairs, a surgical mesh may be placed over the weakened area to reinforce the abdominal wall. In selected situations, stitches alone may be appropriate. The technique is chosen according to the type of hernia, its characteristics and the patient's medical condition.
Laparoscopic Hernia Surgery
Laparoscopic hernia surgery, also known as keyhole hernia surgery, uses a camera and specialised surgical instruments inserted through small incisions.
The surgeon identifies the hernia, returns the protruding tissue to its appropriate position and reinforces the weak area, often using mesh.
Potential advantages of minimally invasive surgery may include:
Smaller surgical incisions
Less postoperative discomfort in appropriate cases
Reduced visible scarring
Earlier mobilisation
Potentially quicker return to routine activities
However, laparoscopic surgery is not automatically suitable for every patient. The choice between laparoscopic and open repair should be made after evaluating the patient's hernia and overall health.
Open Hernia Surgery
In open hernia repair, the surgeon makes an incision directly over or near the hernia. The protruding tissue is returned to its appropriate position and the weakened abdominal wall is repaired.
Open repair remains an established surgical option and may be appropriate depending on the type, size and location of the hernia, as well as the patient's medical circumstances.
What Happens After Hernia Surgery?
Some pain, swelling or bruising around the surgical area can occur during the initial recovery period. Recovery varies from person to person and depends on the type of repair and the individual's health.
Patients are generally advised to:
Follow the surgeon's wound-care instructions
Keep the surgical area clean and dry as advised
Walk and gradually increase activity as recommended
Take prescribed medicines appropriately
Avoid strenuous activity and heavy lifting until cleared by the surgeon
Attend follow-up appointments
For inguinal hernia repair, many patients can return to routine activities relatively quickly, while complete recovery from surgery may take several weeks. The exact timeline should always be discussed with the treating surgeon.
Are There Risks Associated With Hernia Surgery?
Like any surgical procedure, hernia repair has potential risks. These can include:
Infection
Bleeding or collection of fluid/blood
Temporary swelling or discomfort
Difficulty passing urine
Persistent or chronic pain in some patients
Injury to surrounding structures
Recurrence of the hernia
Serious complications are uncommon, but the risks vary depending on the procedure and individual patient factors. Your surgeon should explain the expected benefits, alternatives and possible risks before surgery.
Can a Hernia Be Prevented?
Not every hernia can be prevented because some are related to natural or inherited weakness in the abdominal wall. However, maintaining a healthy lifestyle may help reduce certain risk factors.
Helpful measures include:
Maintaining a healthy body weight
Treating persistent cough
Preventing and managing constipation
Using proper technique when lifting objects
Avoiding unnecessary excessive strain
Stopping smoking, where applicable
Following appropriate exercise and nutrition habits
These measures cannot guarantee that a hernia will not develop, but they can support overall abdominal and physical health.
When Should You See a Surgeon?
Do not ignore a persistent lump or swelling in the abdomen or groin, especially if it is becoming larger or painful.
You should consider a surgical consultation if:
You notice a new abdominal or groin lump
The swelling repeatedly appears while standing or coughing
You experience pain or discomfort during physical activity
The lump is increasing in size
Your daily activities are being affected
You have previously undergone hernia surgery and notice a new swelling
Early evaluation allows the surgeon to understand the condition and discuss whether observation, planned surgery or another approach is appropriate.

Frequently Asked Questions About Hernia
1. Can a hernia heal without surgery?
A hernia generally does not permanently repair itself. Some minimally symptomatic hernias may be monitored under medical guidance, while symptomatic or complicated hernias may require surgery.
2. Is laparoscopic hernia surgery safe?
Laparoscopic hernia repair is an established surgical technique, but like any operation, it has potential risks. Whether it is appropriate depends on the type of hernia and the patient's individual circumstances.
3. How long does hernia surgery take?
The duration varies according to the type and complexity of the repair. For example, NHS guidance notes that inguinal hernia repair commonly takes around 30–90 minutes, although individual procedures can differ.
4. Can a hernia come back after surgery?
Yes. Although hernia repair is intended to provide a durable repair, recurrence can occur in some patients.
5. Is every abdominal lump a hernia?
No. Several conditions can cause a lump or swelling. A medical examination is necessary to determine the actual cause.
