How to Change Your Ostomy Bag Correctly: Tips and Tricks

How often should you change a stoma bag?

Regularly changing your stoma bag (ostomy pouch) is essential for hygiene, skin protection, and optimal performance of your ostomy appliance. The frequency depends on the type of system and stoma:

By system type:

• One-piece systems: Usually changed daily
• Two-piece systems:
  
  • Pouch: changed daily or when needed
  • Baseplate: typically every 2–3 days

By stoma type:

• Colostomy: Closed pouches should be changed when filled
• Ileostomy and urostomy: Drainable pouches should be changed at least daily or when function declines

Signs you must change your ostomy bag immediately

• In case of leaks: If your supply is leaking or the bag spills, it should be changed immediately.
• If adhesion decreases: If the skin barrier plate detaches from the skin, this indicates insufficient adhesion – a change is necessary.
• In case of skin discomfort: An unpleasant sensation under the skin barrier plate, such as burning or itching, may indicate skin irritation and should be taken seriously.
• Based on fill level: If the bag is about half full, a change is recommended – especially for drainable bags. 
  When the filter is exhausted: If the activated carbon filter no longer works effectively, unpleasant odors may occur – a change is also advisable in this case. 
• When the filter is exhausted: If the activated carbon filter no longer works effectively, unpleasant odors may occur – a change is also advisable in this case.

How to prepare for a stoma bag change

Good preparation is key to a smooth and hygienic stoma pouch change. Having everything ready allows you to focus fully on the process.


Essential supplies:

• New supply
• 3–4 moist (water-soaked) wipes or compresses
• 2–3 dry compresses or lint-free soft cloths
• Disposal bag (secured with a clothespin)
• Razor
• Scissors & template
• If needed: adhesive remover, skin protection lotion, skin barrier paste or rings, and a hand mirror


Tip: If your baseplate is not pre-cut, measure your stoma carefully and cut the opening so it fits snugly without pressure.

Step-by-step: How to change a stoma bag

1. Prepare and empty the pouch

If you are using a drainable pouch, empty it beforehand to make handling easier. For ileostomy or urostomy systems, clean the outlet gently.


2. Remove the used stoma bag

Carefully peel the adhesive from top to bottom while supporting your skin. This helps prevent irritation. Use an adhesive remover if needed.


3. Clean the stoma and skin

• Use warm water and soft cloths
• Avoid harsh or oily products
• Clean gently—do not rub


Dry the skin thoroughly, as moisture can reduce adhesive strength.


4. Check the stoma and skin

A healthy stoma should appear pink or red and moist, while the surrounding skin should be intact and irritation-free. If you notice redness, soreness, or discomfort, consult your stoma care nurse.


5. Prepare and apply the new pouch


• Measure and adjust the baseplate opening
• Ensure a close fit (1–2 mm around the stoma)
• Apply gently and smooth from the center outward
• Hold your hand over the adhesive briefly to improve bonding


6. Finish the process


Dispose of used materials and wash your hands. Check that everything feels secure and comfortable.

What to keep in mind before an ostomy appliance

• Skin must be dry: Before applying the appliance, the skin around the stoma should be completely dry. Moisture can significantly reduce the adhesive strength of the baseplate.
• Use appropriate care products: Only use pH-neutral and non-greasy soaps, creams, or wipes. Incorrect products can reduce adhesion and irritate the skin.
• Healthy skin is essential: Intact skin around the stoma is crucial for a secure fit. If there are wounds or irritated areas, consult your stoma nurse or doctor.
• Choose the right timing: Pick a time when your stoma is at rest to ensure a stress-free change:
  
  • With an ileostomy: Changing before breakfast is often optimal, as stoma activity is usually lowest before the first meal. Completely “inactive” periods are hard to predict, but this timing often works best.
  • With a colostomy: Natural rest periods occur throughout the day. The ideal time for a change should be determined according to your personal stoma rhythm.

Showering and bathing with a stoma

Maintaining hygiene is an important part of stoma care, and showering or bathing is completely safe.

Should you shower with or without a stoma bag?

• Colostomy: Often possible without a bag during low activity periods
• Ileostomy/urostomy: Keeping the bag on is usually more practical


Modern ostomy appliances are water-resistant and designed for daily washing.

Tips for showering and bathing with a stoma

Before showering:


• Empty your pouch
• Cover the filter
• Prepare new supplies if needed


During washing: 

• Use warm, not hot water
• Avoid direct water pressure on the stoma
• Use mild, pH-neutral cleansers


After washing:


• Pat skin dry gently
• Avoid oily or alcohol-based products
• Check the seal of your appliance

Skin care around the stoma

Proper stoma skin care is essential to prevent irritation and ensure long wear time of your appliance.

Best practices

• Keep skin clean and dry
• Use fragrance-free, alcohol-free products
• Avoid oily creams near the adhesive area
• Check skin regularly for early signs of irritation


Healthy skin is key to a secure and leak-free ostomy system.

Common mistakes when changing a stoma bag

Avoiding these mistakes can significantly improve comfort and appliance performance:


• Applying a pouch to damp skin
• Cutting the baseplate opening too large or too small
• Touching the adhesive surface
• Ignoring early signs of skin irritation
• Changing the pouch during high stoma activity


Solution: Develop a consistent routine and adjust based on your body’s rhythm

Changing your stoma bag while traveling

• Adequate supply: Take enough ostomy materials – bags, baseplates, cleaning wipes, etc. Ideally, plan for a few extra days’ supply. 
• Carry-on for air travel: Keep all essential items in your hand luggage to ensure access in case of lost checked baggage. 
• Hygiene: Maintain clean conditions, especially in public restrooms. Disinfectant wipes or disposable underpads can be helpful. For travel in Europe, a Euro WC key may be practical for accessing accessible toilets. 
• Travel certificate / stoma passport: A medical certificate (preferably multilingual) makes airport security checks easier. Many suppliers issue a stoma passport with a travel certificate. 
• Storage: Protect your materials from extreme heat or cold, as this can affect the adhesive performance of baseplates. 
• Emergency plan: Research medical contacts at your destination in case any issues with your ostomy care arise.

How to know your stoma bag fits properly

A well-fitted ostomy appliance ensures comfort and security:

• No leaks or odor 
• Skin remains irritation-free 
• Opening fits closely around the stoma 
• Appliance stays secure for hours or days 
• No wrinkles or gaps in the adhesive 

Finding your routine

Adjusting to life with a stoma takes time, and it is normal to feel uncertain at first. With practice, changing your stoma bag and maintaining hygiene becomes quicker and more intuitive.

The most important goal is to find a routine that:

• Protects your skin 
• Ensures comfort and security 
• Fits naturally into your daily life 

Bottom line: Confidence in your stoma care routine

A consistent and well-planned stoma care routine – including regular pouch changes, proper skin care, and good hygiene – ensures long-term comfort and reliability.

 

By using the right techniques and products, you can prevent complications, protect your skin, and maintain a high quality of life.

 

If you ever feel unsure, your stoma care nurse or healthcare professional can provide personalized guidance tailored to your needs.

FAQ: Changing your stoma bag

Can I change my own ostomy bag?

Yes — and in fact, changing your own pouch is something most ostomates manage comfortably and independently after a short period of practice. In the early days following surgery, a stoma care nurse will guide you through the process step by step and be on hand to answer any questions. It is completely normal to feel nervous or uncertain at first, but most people find that with a little time and repetition, pouch changes become a quick and routine part of daily life — much like any other personal care task. If you ever struggle with the process due to limited dexterity, vision difficulties or other physical challenges, your stoma care nurse can suggest adapted techniques or products to make things easier.

How do you change a stoma bag step by step?

Changing a stoma pouch is a straightforward process once you have done it a few times. Begin by gathering everything you need — a new pouch or baseplate, adhesive remover, warm water, a soft cloth or gauze pads and any skincare products you use. Gently remove the old pouch by pressing the skin away from the baseplate rather than pulling the pouch away from the skin, using an adhesive remover spray or wipe to ease the process and protect the skin. Clean the stoma and surrounding skin with warm water and pat the area completely dry. Check the stoma for any changes in colour, size or condition. Cut or fit the new baseplate to the correct size if needed, remove the backing and apply it firmly to the skin, pressing from the stoma outward to avoid air bubbles. Finally, close or seal the new pouch and dispose of the used one hygienically.

Is it painful to change an ostomy bag?

For most people, changing a stoma pouch is not painful. The stoma itself has no nerve endings, which means it does not feel pain — though it may bleed very slightly when touched, which is normal and not a cause for concern. The skin around the stoma can occasionally feel tender, particularly if there is any irritation or if the baseplate is removed too quickly or forcefully. Using an adhesive remover product makes the process much gentler on the skin and significantly reduces any discomfort. If pouch changes are consistently uncomfortable or painful, it is worth speaking to a stoma care nurse, as this may indicate a skin issue or a product that is not the right fit for your individual needs.

How often should an ostomy bag be changed?

The frequency of pouch changes depends on the type of system you use and your individual output. Closed pouches, which are typically used by colostomy patients with more formed output, are usually changed one to three times a day. Drainable pouches — more commonly used with an ileostomy or urostomy — can stay in place for longer, as they are emptied regularly throughout the day rather than replaced each time. The baseplate of a two-piece system can often remain on the skin for three to seven days, depending on the product and how well it adheres. As a general rule, the pouch should be emptied when it is around one third full, and the baseplate should be changed at the first sign of lifting, leaking or skin irritation — rather than waiting until it fails completely.
