What Is a Hernia and When Does It Need Surgery?
A hernia can start as a small, painless lump that appears when you cough, lift, or stand. For some people, it stays mild for a while. For others, it becomes uncomfortable, limits daily activity, or needs surgical repair.
This guide explains what a hernia is, when it may need treatment, and what to expect if surgery is recommended. It is general information only and does not replace personal medical advice from a qualified surgeon.
What is a hernia?
A hernia occurs when an internal part of the body pushes through a weak spot in the muscle or tissue wall that normally holds it in place.
Most hernias involve a bulge under the skin. The bulge may come and go, especially in the early stages. It may be more noticeable when standing, coughing, straining, or lifting, and may flatten when lying down.
Hernias are common, and many are treatable. The key is knowing when symptoms need review.
Common types of hernias
Hernias can occur in different parts of the abdomen and groin.
Inguinal hernia
An inguinal hernia appears in the groin. It is one of the most common types and may cause a lump or dragging discomfort, especially with activity.
Femoral hernia
A femoral hernia also occurs near the groin, slightly lower than an inguinal hernia. It is less common but can have a higher risk of complications.
Umbilical hernia
An umbilical hernia appears near the belly button. It can occur in adults, especially after weight gain, pregnancy, or increased pressure in the abdomen.
Incisional hernia
An incisional hernia can form through a weakness at the site of a previous surgical cut.
Hiatus hernia
A hiatus hernia occurs when part of the stomach moves up through the diaphragm. It may be linked with reflux symptoms rather than a visible lump.
Common hernia symptoms
Symptoms vary depending on the type and size of the hernia. Common signs include:
A visible or felt lump in the groin or abdomen
A bulge that becomes clearer when coughing or standing
Aching, pressure, or a dragging feeling
Discomfort during lifting, bending, or exercise
A burning or heavy sensation around the lump
Symptoms that improve when lying down
Some hernias cause few symptoms at first. Even so, a new lump should be checked, especially if it is growing or becoming painful.
What causes a hernia?
A hernia usually develops when there is both a weak area in the muscle wall and increased pressure pushing against it.
Common risk factors include:
Heavy lifting or repeated straining
Ongoing cough
Constipation and straining on the toilet
Pregnancy
Being above a healthy weight
Previous abdominal surgery
Age-related weakening of tissues
Family history of hernias
Not every hernia is preventable. Good lifting technique, treating chronic cough or constipation, and maintaining a healthy weight may reduce strain on the abdominal wall.
Can a hernia go away on its own?
In adults, a hernia usually does not go away by itself. The opening in the muscle or tissue does not typically close without surgical repair.
Some small hernias can be monitored if they are not painful and have a low risk of complications. This is often called watchful waiting. It should be guided by a doctor or surgeon, because the safest approach depends on the hernia type, symptoms, general health, and lifestyle.
A support garment or hernia belt may help symptoms for some people, but it does not repair the hernia.
When does a hernia need surgery?
Surgery may be recommended when a hernia is painful, enlarging, affecting daily activities, or at higher risk of trapping tissue.
A hernia may need repair if:
Pain or discomfort is increasing
The lump is getting larger
It limits work, sport, walking, or lifting
It does not reduce when lying down
There have been repeated episodes of tenderness or swelling
The hernia type has a higher risk of complications
The aim of surgery is to return the tissue to the correct position and strengthen the weak area, often with surgical mesh.
Open vs laparoscopic hernia repair
Dr. Zeev Duieb will recommend a surgical approach based on the hernia, symptoms, medical history, and patient goals.
Open hernia repair
Open repair uses a single cut over or near the hernia. The surgeon returns the hernia contents to the correct position and repairs the weakness. Mesh may be used to lower the chance of recurrence.
Open surgery may be suitable for many hernias, including larger or more complex hernias.
Laparoscopic hernia repair
Laparoscopic repair uses small cuts and a camera to guide the operation. It may lead to smaller scars and a quicker return to some activities for suitable patients.
This approach is not right for everyone. Previous surgery, hernia size, and overall health can all affect the decision.
What to expect during recovery
Recovery time varies. Many people go home the same day or after a short hospital stay, depending on the operation and their health.
After surgery, patients can usually expect:
Some swelling, bruising, or pulling discomfort
Pain relief medication for the first few days
Gentle walking soon after surgery
Clear instructions about wound care
A gradual return to normal activity
Temporary limits on heavy lifting
Most people return to light daily tasks before they return to strenuous work, gym training, or heavy lifting. Follow-up care helps check healing and guide a safe return to activity.
Warning signs that need prompt medical attention
Seek urgent medical care if a hernia becomes suddenly painful or cannot be pushed back in.
Other warning signs include:
A firm, tender, or discoloured bulge
Nausea or vomiting
Fever
Severe abdominal pain
A swollen abdomen
Inability to pass wind or open the bowels
These symptoms may suggest the hernia is trapped or the blood supply is affected. This can be serious and needs prompt assessment.
Frequently asked questions
Is every hernia an emergency?
No. Many hernias are not emergencies, but they should still be assessed. Sudden pain, vomiting, or a lump that will not go back in needs urgent care.
Can exercise fix a hernia?
Exercise cannot close a hernia. Some exercises may worsen symptoms if they increase abdominal pressure. Ask your doctor before continuing heavy or core-focused training.
Will I need mesh for hernia surgery?
Mesh is commonly used in many hernia repairs because it strengthens the area. The decision depends on the hernia type, size, and individual circumstances.
How soon can I return to work?
This depends on the surgery and your job. Desk-based duties may resume sooner than heavy physical work. Your surgeon will give personalised advice.
Can a hernia come back after surgery?
Recurrence is possible, but careful repair and following recovery instructions can reduce the risk.
