Hernias

Overview

A hernia happens when an organ or fatty tissue pushes through a weak spot in the muscle or tissue that normally holds it in place. Most hernias appear in the belly or groin as a bulge. Some are small and cause no trouble, but others can be painful or lead to serious problems.

Yes, hernias are common. Groin hernias are the most common type, and belly-button hernias are also seen often.

Anyone can get a hernia, but they are more common in men, older adults, and people who lift heavy things or have long-lasting coughing or straining. Babies can have hernias too.

Symptoms

Common symptoms

• A bulge or lump in the belly or groin, which may disappear when you lie down
• Aching or burning feeling at the bulge
• Pain when lifting, coughing, or straining
• A feeling of heaviness or weakness in the area
• Sometimes no symptoms at all

Symptoms in children

• A bulge in the groin or near the belly button, especially when crying or straining
• The bulge may be soft and may push back in
• In babies, a hernia may show up as a swelling that comes and goes
• Pain or fussiness if the bulge is tender

Symptoms in older adults

• A bulge that grows slowly over time
• More aching with activity
• Symptoms may be mistaken for a strain or normal aging
• A higher chance of problems if the hernia is large or has been there a long time

Causes

Main causes

• Weak spots in the muscle wall that some people are born with
• Increased pressure inside the belly from lifting, coughing, or straining
• Straining on the toilet from constipation
• Extra fluid in the belly or a long-lasting cough

Risk factors

• Being male, especially for groin hernias
• Older age and weaker muscles
• Heavy lifting at work or in sports
• Long-lasting cough, constipation, or straining
• Being overweight
• Family history of hernias
• Previous surgery in the belly
• Pregnancy
• Being born early or having a family history of hernias in children

When to see a doctor

See a doctor urgently if:

• A hernia that is painful, firm, or cannot be pushed back in
• Vomiting, bloating, or not passing gas or stool with a hernia
• A child with a painful lump in the groin or belly button

Book a routine appointment if:

• You notice a new bulge or lump
• The bulge aches after activity
• A hernia is getting bigger or bothers you
• You want to talk about treatment choices

Diagnosis

A doctor usually diagnoses a hernia by asking about your symptoms and doing a physical exam. They will look and feel for a bulge, sometimes while you stand, cough, or strain. Many hernias do not need scans.

Tests that may be done

• Physical exam
• Ultrasound, which uses sound waves to make pictures inside the body
• CT scan or MRI in some cases, such as when the diagnosis is unclear
• Blood tests or other tests if surgery is planned

What to expect at your appointment

The check is quick and usually not painful. Your doctor may ask you to cough or stand to make the bulge easier to see. They will explain what type of hernia they think it is and whether you need any tests or treatment.

Treatment

Treatment depends on the type of hernia, your symptoms, and your overall health. Some small hernias that cause no trouble can be watched safely. A hernia that is painful or getting bigger may need surgery. There are no medicines that repair a hernia.

Self-care at home

• Avoid heavy lifting and straining while you wait for advice
• Treat constipation by eating fiber and drinking enough water
• Stop smoking or get help to quit, as coughing can make hernias worse
• Keep a healthy weight
• Use good lifting technique: bend your knees and keep the load close
• Ask your doctor before starting hard exercise

Medical treatments

Doctors may recommend a supportive belt or truss for short-term comfort in some adults, but this does not fix the hernia and should only be used with medical advice. For people who cannot have surgery, doctors focus on managing symptoms and watching for problems. Pain relief can be discussed with your doctor or pharmacist, but medicines do not heal a hernia.

When is surgery considered?

Surgery may be recommended if the hernia is painful, growing, or causing problems, or if there is a risk of it getting stuck. In children, surgery is often advised early to prevent complications. The operation repairs the weak spot, often with a small piece of mesh. Most people recover well, and your surgical team will explain the risks and benefits.

Living with this condition

Most people with a hernia can carry on with normal life while they and their doctor decide what to do. Learn what makes your symptoms worse and avoid those triggers. Check the bulge regularly and know the warning signs of a stuck hernia.

Lifestyle tips

• Stay active with gentle exercise
• Avoid straining on the toilet
• Lift with your legs, not your back
• Ask for help with heavy objects
• Keep a healthy weight
• Stop smoking

Diet and exercise

Eat plenty of fiber from fruits, vegetables, and whole grains, and drink enough water to keep stools soft. Gentle exercise like walking can help. Ask your doctor or a physiotherapist about safe core exercises and what to avoid.

Mental health and emotional wellbeing

A hernia can cause worry, especially if you are waiting for surgery or have pain. It is normal to feel anxious. Talk to your doctor about your concerns and ask what symptoms mean. Support from family, friends, or a counselor can help. If you feel you are in crisis, contact your local emergency number or a mental health crisis service in your country.

Prevention

You cannot prevent every hernia, especially those you are born with. But you can lower pressure on your belly muscles by avoiding heavy straining, treating constipation, not smoking, and keeping a healthy weight.

Vaccines

There is no vaccine that prevents hernias.

Screening programmes

There is no routine screening for hernias. See your doctor if you notice a bulge or have pain.

Complications

If left untreated

• A hernia can get bigger and more uncomfortable
• It can become stuck in the weak spot, which is called an incarcerated hernia
• The blood supply can be cut off, which is called a strangulated hernia and is an emergency
• Bowel blockage can cause vomiting, bloating, and severe pain

Long-term outlook

Most hernias can be managed safely. Many people live normal lives with a hernia, and surgery is usually very successful when needed. Seeing your doctor early helps you make a good plan.
