What is a stoma hernia?
A stoma hernia (also called a parastomal hernia) is something most ostomates experience after their stoma surgery. In simple terms, a stoma hernia is a bulging of tissue or bowel through a weak point in your abdominal wall at the stoma opening.
When your stoma was created, a hole was made in your abdominal muscles to bring your bowel to the surface. This creates a natural weak spot: and over time, increased pressure in your abdomen can push tissue through that weak spot and create a visible bulge.
Again, stoma hernias are very common and are usually manageable without surgery, and most people live well with them once they understand what's happening.
Symptoms of a stoma hernia
Visual and physical signs of a stoma hernia
The most obvious sign of a parastomal hernia is a visible or palpable bulge around your stoma. You might notice a change gradually over weeks or months, or sometimes even suddenly. The bulge is usually soft and feels like a pocket of tissue beneath the skin.
A stoma hernia looks like:
- A soft swelling or bulge near or around your stoma
- Your stoma looks larger, flatter, or shifted from its normal position
- The swelling is more obvious when you're standing (gravity pulls it down) and may reduce when you're lying flat
- The bulge might increase in size as the day goes on, especially if you've been active
Symptoms you might feel if you have a stoma hernia
Apart from visible changes, you may also go through discomfort:
- Pressure or pulling sensation: You might feel heaviness or tightness in your abdomen, especially around the hernia area.
- Difficulty securing your pouch: A hernia changes the contour of your abdomen. Your baseplate might not stick as well, or the shape of your stoma means your normal pouch no longer fits properly.
- Bloating or fullness: You might feel fuller faster when eating or experience more gas and bloating than before.
- Pain or discomfort: Some people feel a dull ache or pressure, especially after standing for long periods or lifting. Others feel nothing at all.
- Changes in stoma function: Your output might change slightly, or you might notice your stoma is less predictable.
- Difficulty with certain movements: Coughing, lifting, or bending might trigger discomfort.
You don’t have any discomfort? Having a hernia doesn't automatically mean you'll have pain or complications. Some people notice their stoma hernia symptoms only because they see the bulge visually and yet feel completely fine. The hernia may be there but not be causing problems. This is very common.
Stoma hernias: When are they dangerous?
Most stoma hernias are not dangerous, but some do require extra attention. Here’s how you can spot the difference:
When a hernia is not dangerous
A typical parastomal hernia is manageable. You can see the bulge, you might feel some discomfort, but your stoma functions as it should and you can live your life. Most hernias are this type. They don't require emergency surgery; they need to be properly managed and monitored instead.
When a hernia becomes dangerous
A stoma hernia that is strangulated is a red flag. A strangulated hernia means the tissue pushing through the weak spot has lost its blood supply (the muscle has tightened around it like a tourniquet). This is a medical emergency.
Signs of a strangulated hernia are:
- Severe, sudden pain around your stoma
- Your stoma changes colour (darkens to purple or black)
- Your stoma feels hard or cold to the touch
- Severe nausea or vomiting
- Your stoma stops producing output completely
- Redness, warmth, or swelling that appears suddenly
A strangulated hernia needs emergency surgery within hours. If you experience these signs, go to A&E immediately. Don't wait.
Incarcerated hernias
An incarcerated hernia is tissue trapped in the weak spot but still has some blood supply. It's painful and uncomfortable but not immediately life-threatening. However, it can progress to strangulation if not treated, so it needs prompt medical attention.
Signs of an incarcerated hernia:
- Sudden increase in pain
- Swelling that worsens and doesn't reduce when lying down
- Nausea
- Inability to empty your pouch normally
Contact your stoma care nurse or GP same day if you suspect an incarcerated hernia. Don't wait for an emergency.


Living with a stoma hernia: Management options
Conservative management (surgery-free)
Most people manage their hernias without surgery, sometimes for years. Conservative management involves:
Pouch adjustment: Your stoma care nurse can help fit a pouch that works better with your hernia. Sometimes a different shape or size accommodates the bulge more comfortably.
Support garments: Specially designed support belts or binders help reduce the bulge and provide comfort. These are worn over your pouch and give external support without restricting your circulation.
Barrier products: Stoma seals and rings may help your pouch stay secure even with the changed anatomy.
Lifestyle modifications: Avoiding heavy lifting, managing constipation, maintaining healthy weight, and not straining all reduce pressure and prevent the hernia from worsening.
Regular monitoring: Check your hernia regularly to spot any changes early.
When surgery might be considered
Surgery (hernia repair) is an option if:
- The hernia significantly impacts your life quality: Pain is severe, pouch security is impossible, or you can't do normal activities.
- The hernia is growing rapidly: If it's increasing in size noticeably month to month, surgery might be recommended to prevent complications.
- There's a risk of strangulation: If your anatomy suggests strangulation is likely, surgery is preventative.
- Complications develop: If you've had episodes of incarceration or strangulation, surgery is warranted.
Surgery for parastomal hernia repair has risks (it can recur, it requires general anaesthesia, recovery takes time) and benefits (pain relief, peace of mind). Your surgeon will help you weigh them. Many people live well without surgery, and others find surgery gives them back their quality of life. It all depends on your personal experience.
How to manage a stoma hernia
Reduce pressure on your abdomen
Avoid heavy lifting: Don't lift more than 5–10 kg without support. If you must lift, wear a support belt.
Prevent constipation: Constipation increases pressure. Stay hydrated, eat adequate fibre (gradually), and manage bowel movements proactively.
Manage your cough: If you smoke, quitting is the single best thing for your hernia risk. If you have asthma or COPD, work with your doctor to control coughing.
Maintain healthy weight: Extra abdominal weight increases pressure constantly. Even modest weight loss helps.
Have good posture: Slouching increases intra-abdominal pressure. Sitting and standing upright helps.
Move gently
- Regular, gentle movements: Walking, stretching, and swimming are all fine. Competitive sports, intense gym work, and core exercises should be avoided unless approved by your surgeon.
- Avoid sudden movements: No jumping, explosive exercises, or high-impact activities.
- Support yourself: When coughing, sneezing, or lifting anything, brace your abdomen with your hand or a support garment.
Nutrition and wellness
Eat well: Adequate protein, vitamins, and minerals support tissue strength. Avoid crash diets; slow, sustainable changes work better.
Stay hydrated: Dehydration leads to constipation which, again, increases pressure.
Don't smoke: Smoking weakens connective tissue and significantly increases hernia risk and complications.
Manage stress: Stress affects digestion which can also lead to constipation. Manage your stress through relaxation, movement, and support.
Monitor regularly
Check your hernia weekly. Look for:
- Changes in size
- Changes in colour
- New pain or discomfort
- Changes in how your pouch fits
- Any symptoms of strangulation
Small, gradual changes are normal. Sudden deterioration needs professional assessment.
When to seek medical help
Contact your stoma care nurse or GP if:
The hernia grows noticeably: High increase in size month to month isn’t normal and asks for medical help.
Pain increases: New or worsening pain needs evaluation.
Your pouch won't stay secure: Recurring stoma leakage due to the hernia requires professional help.
You see signs of strangulation: Colour changes, sudden severe pain, or hard swelling need immediate attention (A&E).
You feel unwell: Nausea, vomiting, or feeling unwell alongside the hernia needs evaluation.
You have questions about surgery: If the hernia is affecting your quality of life, discuss repair options with your surgeon.
Key takeaways on stoma hernias
Stoma hernia symptoms include visible bulging around your stoma, discomfort or pressure, and sometimes difficulty fitting your pouch. However, there are many people who have no symptoms at all.
Hernias are common after stoma surgery and usually manageable without surgery. They ask for monitoring but not panic.
A strangulated stoma hernia is rare but serious: severe pain, colour changes, or complete output stoppage need emergency attention.
Most people manage hernias through conservative measures such as appropriate pouch fitting, support garments, pressure reduction, and gentle movement. Surgery is an option if the hernia impacts quality of life significantly.
Your stoma care nurse is your best resource. They can assess your specific hernia, recommend management strategies, and help you decide if surgery is appropriate for you.
FAQ: Stoma hernia
Can a stoma hernia go away on its own?
No. Once tissue pushes through the weak spot in your abdominal wall, it doesn't go back on its own. Hernias stay the same size, shrink very slightly, or grow over time but they can’t go away without surgery. However, "not going away" doesn't mean "needs surgery." Many people have stable hernias that never cause problems and never need surgery in the first place. The hernia itself is permanent but manageable.
Will wearing a support belt make my hernia worse?
No. A properly fitted support belt gives you extra support and helps you prevent the hernia from getting worse. It reduces pressure on the weak spot and gives you comfort. Make sure the belt isn't too tight (that restricts circulation), and work with your stoma care nurse to find one that fits well and feels comfortable.
Can exercise make a stoma hernia worse?
Intense exercise and heavy lifting can increase hernia size, especially core-focused exercises like crunches or planks. Gentle exercise like walking, swimming, or yoga is fine. Competitive sports or high-impact activities should be avoided. Talk to your surgeon about what's safe for you specifically as some people can do more than others depending on their hernia size and how stable it is.
What's the difference between a hernia and other abdominal swelling?
A stoma hernia is a specific bulging of tissue through a weak spot in muscle. You can usually feel the edges of the bulge, and it changes size with position (worse standing, better lying down). General abdominal swelling from bloating, weight gain, or fluid is more diffuse and doesn't have defined edges. If you're unsure which one you have, your stoma care nurse can examine you and tell you what you're dealing with.
If I have a hernia, can I still travel or do normal activities?
Yes. Most people with hernias travel, work, exercise (gently), and live normal lives. The key is understanding your individual hernia; what makes it uncomfortable, what helps, and what to avoid. Wear a support belt if it helps. Avoid heavy lifting. Manage constipation. If your hernia is causing too much restriction, that's when surgery becomes worth considering.
