Will my stoma bag leak, and how do I stop it?
Leaks can happen, especially in the early weeks while you learn your kit, but they are usually a fit problem you can solve rather than something you have to put up with. The most common cause is a barrier opening cut too large, so output slips under the seal and loosens it. The fixes are practical: cut the opening to match your stoma, make sure the skin is clean and dry before sticking the bag on, and fill any dips or creases around the stoma with accessories like stoma paste or a seal/barrier ring so the surface is flat. If you cannot work out why it keeps leaking, your stoma care nurse can find the cause.

Leaks are one of the most common early worries, and it is honest to say they can happen, particularly in the first weeks while you are still learning your kit. The reassuring part is that a leak is almost always a fit problem with a practical fix, not something you simply have to live with.
Why bags leak
The usual culprit is the seal. UChicago Medicine explains that if the opening in the skin barrier is cut too large, stool can make contact with the skin and loosen the adhesive seal (UChicago Medicine). Other things make this more likely: skin that was damp when the bag went on, dips or creases around the stoma that leave gaps, heavy or watery output, and heat or sweat loosening the adhesive.
What actually helps
The fixes follow from the causes:
- Cut the barrier opening to match the size and shape of your stoma, so output goes into the bag instead of under it.
- Clean and fully dry the skin before applying a fresh bag.
- Fill any uneven spots. Accessories such as stoma paste or a seal/barrier ring smooth out dips and creases so the surface around the stoma is flat. Colostomy UK notes a seal, or even a different type of pouch, can help create that flat surface, and that there are products available to help protect the skin (Colostomy UK).
When to ask for help
You do not have to put up with repeated leaks. If you cannot work out why it keeps happening, that is exactly what the stoma clinic is for: UChicago Medicine advises that the ostomy nurses can evaluate a pouching system that keeps leaking and help correct the cause (UChicago Medicine). A change of product or a small technique tweak often fixes it.
