A lump in the groin, a swelling around the belly button or a bulge that becomes more noticeable when lifting something heavy may not seem like a serious problem. Some people ignore it for months, assuming it is simply a muscle strain or a sign of getting older.
But it could be a hernia.
Hernias are common in both men and women, although the type of hernia and the way it presents can differ. Some cause little discomfort, while others can lead to a medical emergency if part of the intestine becomes trapped.
From the community pharmacy counter, one of the most important things we can do is recognise the warning signs, explain what people should look out for and encourage them to seek medical assessment rather than relying on painkillers or supportive garments to manage the problem indefinitely.
What exactly is a hernia?
A hernia occurs when an internal organ or tissue pushes through a weak area in the muscle or surrounding tissue that normally holds it in place.
Imagine the abdominal wall as a strong sheet of material. If a weak point develops, pressure from inside the abdomen can push tissue through that opening, producing a visible or sometimes hidden bulge.
Hernias can develop at different points in the body, but those affecting the groin and abdomen are among the most common. They may become more noticeable when coughing, lifting, standing for long periods or straining during a bowel movement.
Some hernias disappear temporarily when a person lies down. This does not mean the underlying weakness has healed.
The NHS provides a useful overview of the different types and their symptoms: NHS – Hernia.
Why are men more likely to develop certain hernias?
Inguinal hernia: particularly common in men
An inguinal hernia develops when tissue pushes through a weak area in the groin. It may produce a bulge that extends towards the scrotum.
Men are more susceptible because of the anatomy of the inguinal canal, through which structures associated with the testicles pass during development.
Typical symptoms include:
- A lump in the groin that becomes more noticeable when standing, coughing or lifting.
- An ache, dragging sensation or feeling of pressure in the groin.
- Discomfort when bending, exercising or carrying heavy objects.
- Swelling that reduces or disappears when lying down.
Some men have a noticeable lump but very little pain. Others experience discomfort that gradually interferes with everyday activities.
It is important not to assume that every groin lump is a hernia. Swollen lymph nodes, cysts and other conditions can produce similar symptoms and need different management.
What about women? Hernias are not just a man’s problem
Women can develop several types of hernia, but groin hernias deserve particular attention because the symptoms may be less obvious.
Femoral hernia: an important warning for women
A femoral hernia occurs when tissue pushes through a weak point near the top of the inner thigh, just below the groin crease.
Femoral hernias are less common than inguinal hernias overall, but they occur more frequently in women, particularly older women.
The signs can be subtle:
- A small lump or swelling at the top of the inner thigh.
- Discomfort in the groin when walking, standing or lifting.
- A dragging sensation or unexplained groin pain.
- A swelling that appears during coughing or straining.
The concern is that a femoral hernia has a higher risk of becoming trapped or strangulated. This means the bowel can become stuck in the opening and its blood supply may be cut off.
For this reason, a suspected femoral hernia needs prompt medical assessment, and surgery is generally recommended rather than prolonged observation. NHS – Femoral hernia repair.
Umbilical hernia: the swelling around the belly button
An umbilical hernia develops when tissue pushes through a weak spot around the navel.
It affects both sexes and may occur in adults who are overweight, have had pregnancies, or experience increased pressure inside the abdomen.
Women may notice one after pregnancy, while men can develop one in association with excess abdominal weight or repeated straining.
The swelling may be painless initially, but it can become uncomfortable or tender, especially when coughing or lifting.
A bulge around the belly button should not automatically be dismissed as a cosmetic issue. A GP can assess whether it is a hernia and whether repair is necessary.
Incisional hernia: following abdominal surgery
An incisional hernia develops through a weakened area where an abdominal operation was previously performed.
It can affect men or women, sometimes months or years after surgery. A bulge may appear around the surgical scar and become more obvious when standing or straining.
Previous abdominal surgery, wound complications and increased pressure within the abdomen can contribute to the risk.
If a new swelling appears near an old surgical scar, it is worth arranging an assessment rather than assuming it is simply scar tissue.
What causes a hernia?
There is rarely one single cause. Often, a hernia develops because of an existing weakness in the abdominal wall combined with pressure from inside the abdomen.
Factors that may contribute include:
- Ageing and weakening of muscle or connective tissue.
- A family history of hernias.
- Persistent coughing.
- Chronic constipation and repeated straining on the toilet.
- Being overweight or obese.
- Pregnancy and repeated pregnancies.
- Heavy lifting, particularly when it involves straining.
- Previous abdominal surgery.
Heavy lifting is often blamed, but it is not the whole story. A hernia can develop even in someone who has never lifted heavy weights. Equally, having a physically demanding job does not mean a person will inevitably develop one.
The National Institute of Diabetes and Digestive and Kidney Diseases explains the role of abdominal wall weakness and increased pressure in its guide to inguinal hernias.
When does a hernia become dangerous?
This is the part of the conversation I would never want patients to overlook.
A hernia can become incarcerated, meaning the tissue inside it becomes trapped and cannot return to the abdomen. If the blood supply is then cut off, it is called a strangulated hernia.
Without urgent treatment, the affected tissue can become damaged. If bowel is involved, this can become life-threatening.
Warning signs that need emergency assessment
- Sudden or severe pain around the hernia.
- A lump that becomes hard, very tender or discoloured.
- A previously reducible lump that will no longer go back in.
- Vomiting, abdominal swelling or inability to pass wind or stools.
- A painful lump accompanied by fever or feeling seriously unwell.
If these symptoms occur, go to A&E immediately or call 999 if severely unwell. Do not wait for a routine GP appointment or try to force the lump back inside.
These warning signs are consistent with the NHS guidance on hernias and the NIDDK’s advice on complications.
Can a hernia be treated without surgery?
This is one of the most common questions patients ask.
The honest answer is that medicines, exercise and dietary changes cannot close the opening in the abdominal wall. They may help manage contributing factors or discomfort, but they do not repair the hernia itself.
Treatment depends on the type of hernia, its symptoms and the patient’s overall health.
Watchful waiting: Some men with an inguinal hernia that causes no symptoms or only minimal discomfort may be offered monitoring after medical assessment. This is not suitable for every hernia, and symptoms can develop or worsen over time.
Women with suspected groin hernias generally need a more cautious approach because a femoral hernia may be present but difficult to identify. Early surgical assessment is important.
Surgical repair: The surgeon returns the protruding tissue to its proper position and repairs the weak area. This may involve stitches, surgical mesh or a combination, depending on the circumstances. Surgery can be performed through an open incision or by keyhole techniques.
Many patients go home on the day of surgery, although this depends on the procedure and their health. Recovery varies, so patients should follow the surgical team’s advice about lifting, exercise and returning to work.
For further information, see the NHS guide to inguinal hernia repair.
What can a community pharmacist advise?
A pharmacist cannot confirm a hernia simply by looking at a lump across the counter. Other conditions can cause similar symptoms, and examination may be needed.
However, there are several practical ways we can help.
1. Do not mask an unexplained lump with painkillers. Pain relief may reduce discomfort without addressing the underlying problem. A new groin or abdominal lump should be assessed by a GP.
2. Address constipation. Straining increases pressure in the abdomen. Adequate fluid intake, dietary fibre and appropriate treatment for constipation may help reduce straining, although they will not repair a hernia.
3. Review persistent coughing. A cough that continues for weeks should be investigated rather than repeatedly treated with over-the-counter remedies.
4. Be sensible about lifting. Avoid activities that provoke pain or marked straining while awaiting assessment. There is no universal lifting limit for everyone with a hernia, so advice should be tailored to the individual.
5. Be cautious with hernia belts and supports. These do not cure a hernia and are not appropriate for everyone. Anyone considering one should discuss it with a healthcare professional, particularly if the lump is painful or difficult to reduce.
6. Check pain relief is suitable. Paracetamol may be appropriate for some people, but persistent or worsening pain needs assessment rather than repeated self-medication. Anti-inflammatory medicines such as ibuprofen are not suitable for everyone, particularly people with certain stomach, kidney or cardiovascular conditions or those taking medicines that increase bleeding risk.
Can hernias be prevented?
Not every hernia can be prevented, particularly when an underlying weakness is present. Nevertheless, sensible measures can help reduce avoidable pressure on the abdominal wall.
Maintaining a healthy weight, staying physically active, avoiding smoking, treating persistent coughing and preventing chronic constipation are useful steps.
When lifting, use an appropriate technique and avoid holding your breath and straining excessively. If an activity repeatedly produces groin pain or a bulge, stop and seek advice.
These measures support general health, but they should never be presented as a guarantee against hernia development.
The message I want readers to remember
A hernia is not always painful, and a painless lump is not necessarily harmless. Men are particularly prone to inguinal hernias, while women need to be especially alert to the possibility of a femoral hernia.
If you notice a new lump around your groin, belly button or an old surgical scar, arrange a medical assessment. Do not wait for it to become painful.
And if a hernia becomes suddenly painful, hard or discoloured, especially with vomiting or abdominal swelling, seek emergency help.
As community pharmacists, we often meet people at the point when a small concern first becomes a question. Sometimes the most valuable advice we can give is not which medicine to buy, but when a symptom deserves proper investigation.
Until next time, take care of your health.
