Stoma leaks and sore peristomal skin are common, usually fixable problems. The most frequent causes include a poor pouch fit, trapped moisture, enzyme burn from stoma output, allergic reactions, yeast infections, or physical changes like stoma retraction or a parastomal hernia.
Medically approved next steps include:
Seek urgent care for spreading redness, deep ulcers, fever, severe pain, dehydration, or a discolored (dusky, black, or pale) stoma.
Because stoma and skin issues can stem from many different causes—some minor, some serious—understanding your specific symptoms is the fastest way to know what to do next. A free, instant, online symptom check can help you identify likely causes, flag red flags, and guide your next steps in minutes—no signup required. It's a smart first move before booking an appointment or heading to urgent care.

Not seeing your question? No worries.
Submit your own QuestionIf your stoma is leaking and your skin feels sore, raw, or broken down, you are not alone. Peristomal skin problems (skin around the stoma) are one of the most common complications for people with an ostomy. The good news? Most causes are treatable — and preventable — with the right steps.
This guide explains why stoma leakage happens, why your skin may be "failing," and what medically approved next steps you should take.
A stoma should drain into a well-fitted pouching system without leaking onto the surrounding skin. When leakage happens, it usually comes down to one or more of the following:
Your stoma can change size and shape, especially:
If the opening in the skin barrier is too large, stool or urine can touch the skin. Even small gaps can cause irritation.
Stool — especially from an ileostomy — contains digestive enzymes. These enzymes can literally digest the skin if they sit on it. Urine from a urostomy can also irritate skin, especially if infection is present.
When skin becomes irritated, the barrier won't stick properly. That leads to more leaks — and a worsening cycle.
The barrier needs dry skin to seal properly. If your skin is:
The adhesive may fail.
Some people react to:
This causes redness, itching, and sometimes blistering.
If the skin looks:
You may have a yeast infection. This is common in warm, moist areas under an appliance.
If the stoma sinks below skin level or the abdominal shape changes, it becomes harder for the appliance to seal correctly.
Healthy peristomal skin should look like the skin on the rest of your abdomen.
Warning signs include:
If you're experiencing any of these warning signs and want to identify what might be causing your peristomal skin changes, this free Abnormal skin symptom checker can help you understand your symptoms and determine your next steps.
It's not just about comfort.
Untreated skin damage can lead to:
While most cases are manageable, ignoring ongoing stoma leakage can turn a minor irritation into a serious issue.
Here's what ostomy nurses and colorectal specialists typically recommend.
Especially if:
Use a stoma measuring guide. The barrier opening should be 1–2 mm larger than your stoma, not wider.
If your stoma shape is irregular, consider:
An ostomy nurse can help refit your appliance properly.
If skin is already irritated:
Avoid:
These interfere with adhesion and delay healing.
If you suspect a fungal infection:
If skin is severely painful, oozing pus, or spreading redness appears, see a doctor urgently.
Depending on your issue, you may benefit from:
An ostomy nurse can assess abdominal contours and recommend the best option.
If you notice:
You may have a parastomal hernia. These are common.
Mild cases are managed with:
Severe cases may require surgical evaluation.
Common mistakes include:
General best practices:
Do not delay medical care if you notice:
These can signal serious complications that require prompt treatment.
When in doubt, speak to a doctor. Some stoma complications can become life-threatening if ignored.
In most cases, yes.
Peristomal skin heals well once:
Healing may take:
The key is breaking the leak–irritation cycle early.
Once your skin improves, prevention becomes the priority.
Early intervention prevents major setbacks.
If your stoma is leaking and your skin is breaking down, it's not a personal failure — it's usually a fit or skin protection issue. Most causes are mechanical and fixable.
However, untreated leakage can lead to serious skin damage and infection. Do not ignore persistent redness, pain, or open areas.
Start with:
If you're dealing with unusual redness, irritation, or breakdown around your stoma and need help determining the cause, you can check your Abnormal skin symptoms using a free AI-powered tool to get personalized recommendations before your next appointment.
And most importantly, speak to a doctor about any symptoms that could be serious or life-threatening.
With the right adjustments, most stoma leakage problems can be resolved — and your skin can recover.
