A new bulge around your stoma can be worrying. You may notice it when standing, coughing or moving and immediately wonder whether something has gone wrong with your stoma or whether you have done something to cause it.

A hernia can occur after stoma surgery, and a parastomal hernia develops in the area around the stoma. It does not necessarily mean you have done anything wrong. Understanding the signs, knowing how to protect your abdominal area and getting appropriate advice can make the situation feel much less frightening.

What Is a Parastomal Hernia?

A parastomal hernia is a weakness in the abdominal wall around a stoma. Part of the tissue inside the abdomen can push through this weaker area, creating a swelling or bulge beside or around the stoma.

Some parastomal hernias cause few or no symptoms. Others can affect comfort, movement or the way a stoma bag fits. If you notice a new or changing bulge around your stoma, it is sensible to mention it to your stoma nurse or GP rather than trying to diagnose it yourself.

A parastomal hernia after stoma surgery can develop gradually, so you may not notice it immediately after your operation.

What Does a Parastomal Hernia Feel or Look Like?

The appearance can vary from person to person. One common sign is a soft swelling beside or around the stoma that becomes more noticeable when you are standing, coughing or straining.

You might also notice changes in how your usual stoma bag sits against your skin.

Possible signs include:

• A new bulge or swelling around the stoma
• A feeling of heaviness or pulling around the abdominal area
• Discomfort when coughing, bending or moving
• Changes in the shape of the area around your stoma
• Difficulty getting your usual pouching system to fit comfortably
• More frequent leaks because the abdominal surface has changed

Not every bulge is a hernia, however. Your stoma nurse, GP or another healthcare professional can assess what is happening and advise you about the next steps.

When Should You Contact Your GP or Stoma Nurse?

A suspected parastomal hernia does not always require emergency treatment, but new symptoms should not simply be ignored.

Contact your stoma nurse or GP if you develop a new lump, increasing discomfort or repeated problems with your stoma bag fitting. They can assess the area and, if necessary, arrange further assessment.

Seek urgent medical help if symptoms are severe

If you experience severe or rapidly worsening abdominal pain, persistent vomiting, significant abdominal swelling, or major changes in your stoma output alongside feeling unwell, seek urgent medical advice.

A stoma that changes colour significantly or appears unusually swollen should also be assessed promptly. If you are unsure whether your symptoms are urgent, contact NHS 111 or seek appropriate medical care.

Can You Prevent a Hernia After Stoma Surgery?

There is no guaranteed way to prevent a parastomal hernia. Your individual risk can depend on factors such as the type of surgery, the position of the stoma, the strength of the abdominal wall and other aspects of your health.

However, following your surgical team’s advice can help you protect your abdomen while recovering.

1. Follow your lifting advice after surgery

After an operation, your abdominal muscles and tissues need time to recover. Your surgical team or stoma nurse can advise you about when and how to gradually return to lifting and other physical activities.

Avoid suddenly returning to heavy lifting simply because your incision appears healed. If your work, exercise or daily routine involves lifting, ask your healthcare team how to increase activity safely.

2. Use good technique when moving

If you need to lift something, your stoma nurse or physiotherapist may be able to demonstrate safer movement techniques.

Try to avoid sudden, forceful movements and remember that everyday activities such as getting out of bed, coughing and carrying shopping can also place pressure on your abdominal muscles.

3. Discuss exercise with your healthcare team

Gentle movement is often an important part of recovery, but the right activities and timing depend on your surgery and individual circumstances.

Once your healthcare team says it is appropriate, ask about exercises that can help you gradually rebuild abdominal strength without placing excessive strain on your healing tissues.

Can a Hernia Support Belt Help?

A hernia support belt for stoma patients may provide additional support around the abdominal area for some people. These garments are designed to offer gentle support and can sometimes make certain activities feel more comfortable.

However, a support belt is not suitable for everyone and should not be treated as a way to cure or permanently prevent a hernia.

If you are considering one, speak with your stoma nurse first. They can help you determine whether a support garment is appropriate and advise you on choosing the correct size and design around your particular stoma.

A belt that is too tight or poorly fitted may cause discomfort and could interfere with your stoma bag or appliance.

Choosing Products When You Have a Hernia

A change in the shape of your abdomen can make your usual stoma care routine more difficult. You may find that your appliance no longer sits exactly as it did before.

This does not mean you have to put up with constant leaks or discomfort.

Your stoma nurse can help you review your pouching system and consider whether you need a different appliance, accessories or fitting approach. Depending on your circumstances, products such as support garments, barrier products or different pouching systems may be discussed.

Keep stoma care as simple as possible

When the area around your stoma changes, it can be tempting to keep adding products in the hope that something will solve the problem. Instead, make one change at a time where possible and ask your stoma care team for guidance.

A comfortable, well-fitting system should work with the shape of your abdomen rather than forcing your body to fit around the product.

Practical Steps If You Think You Have a Hernia

If you have noticed a new bulge around your stoma, try this simple approach:

1. Make a note of the change. Notice when the swelling appears and whether it changes when you stand, cough or lie down.
2. Check your stoma bag fit. Look for new pressure points, creasing or leakage.
3. Contact your stoma nurse or GP. Explain what you have noticed and how long it has been happening.
4. Ask before using a support belt. Your healthcare professional can advise whether one is appropriate for you.
5. Follow personalised activity advice. Do not assume that exercises or lifting recommendations for someone else will be suitable for your recovery.
6. Get urgent help for severe symptoms. Particularly if you have significant pain, vomiting, marked swelling or concerning changes to your stoma or output.

Living With a Parastomal Hernia

Being told that you may have a hernia can feel unsettling, particularly when you are already adjusting to life with a stoma. But a hernia does not automatically mean that your stoma will stop working or that you will need another operation.

Management depends on your symptoms and individual circumstances. Some people may be monitored and supported with changes to their stoma care routine, activity advice or suitable support garments, while others may need further specialist assessment.

If you are worried, your stoma nurse is an excellent first point of contact. In the UK, your GP can also assess your symptoms and arrange further care when needed.

Organisations such as Colostomy UK and IA (the Ileostomy & Internal Pouch Association) also provide information and support for people living with a stoma.

Remember: You Haven’t Failed Your Recovery

A parastomal hernia can happen even when you have followed your medical team’s advice carefully. Developing one is not necessarily a sign that you lifted something incorrectly or somehow caused your surgery to fail.

What matters is recognising changes, getting appropriate advice and finding a stoma care routine that keeps you comfortable and confident.

If you are looking for ways to make everyday stoma care easier, Colo-Majic’s biodegradable ostomy liners can be another practical part of your routine. You can also ask about free samples to see whether the liners suit your needs before making them part of your regular stoma care.
