How to Change a Colostomy Bag Without Damaging the Skin

Living with a colostomy means you’ll need to change your pouch regularly. Learning how to change a colostomy bag the right way can keep your skin healthy, prevent leaks, and boost your confidence. This guide walks you through each step in clear, simple language—no sugar-coating, just practical advice.

Why Proper Technique Matters

Changing your bag carefully:

• Protects the delicate skin around your stoma
• Reduces the risk of irritation, redness or infection
• Helps your pouch adhere better and last longer
• Gives you control over a daily routine

Taking five extra minutes for each change can save you discomfort and extra supplies down the road.

What You’ll Need

Gather everything before you start. Having your supplies within reach keeps the process smooth.

• Clean colostomy pouch and skin barrier (flange)
• Scissors (if cutting the barrier to size)
• Warm water and mild, fragrance-free soap
• Soft washcloths or disposable wipes
• Skin barrier paste or powder (as recommended)
• A mirror (to check seal and fit)
• Paper towel or cloth to catch any spills
• Disposal bag for the used pouch

Lay items out on a clean, dry surface—ideally a table or counter at waist height.

Step-by-Step Guide

1. Prepare Your Supplies

• Inspect the new barrier ring and pouch for defects.
• If your barrier needs trimming, place it over your stoma and cut carefully around the pattern ring. Aim for a snug fit—about 1–2 mm larger than the stoma.
• Open the pouch packaging so it’s ready.

2. Empty the Current Bag

• Sit or stand over the toilet.
• Unclip or unwrap the bottom of your pouch and let contents drain.
• Use a little toilet paper in the pouch to absorb any drips, then re-seal the end.
• Dispose of paper and any waste appropriately. Wash your hands.

3. Remove the Old Bag

• Gently lift an edge of the flange or adhesive barrier, pulling toward your skin, not away from it, to avoid tugging.
• Peel slowly and support the skin with the other hand to minimize discomfort.
• Dispose of the old pouch in a disposal bag.

4. Clean the Skin

• Use warm water and a soft washcloth or fragrance-free wipe to clean around the stoma.
• Pat the skin dry with a clean towel—do not rub.
• Check for redness, irritation, or raised areas. If you spot anything concerning, consider a free, online symptom check, using the doctor approved Ubie Symptom Checker.

5. Apply Skin Barrier

• If you use stoma powder for moisture, sprinkle a thin layer and brush off excess.
• For minor creases or dips, apply a small amount of barrier paste to fill gaps. Let it dry until tacky.
• Peel the backing from the barrier ring or flange.

6. Attach the New Bag

• Center the opening of the barrier exactly over your stoma.
• Press firmly around the entire edge—start at the bottom, move to the sides, then the top.
• Run your palm around the seal again to ensure full contact.
• If using a two-piece system, click or snap the pouch onto the barrier plate until you hear a secure “seal.”

Check the fit with a mirror. You should see no gaps or lifted edges.

Protecting Your Skin

Healthy skin is key to comfort:

• Change your pouch every 3–5 days or sooner if you notice lifting, leaks, or redness.
• Avoid alcohol-based cleansers or baby wipes with fragrance—they can dry out and irritate skin.
• Use a barrier spray or wipe under your flange if you sweat heavily or live in a humid climate.
• Keep excess hair trimmed around the stoma to help the pouch stick better and reduce tugging.

If you develop persistent redness, itching, or burning, you may have a contact allergy to your pouch material. Speak to your doctor about trying a different flange or adhesive.

Tips for Comfort and Confidence

• Change your pouch at a time of day when your output is lowest—often first thing in the morning or between meals.
• Sit on the toilet with a disposable pad or a folded towel across your lap if you’re concerned about spills.
• Wear high-waisted underwear or a snug ostomy belt to keep your pouch discreet and close to your body.
• Practice in front of a mirror until you feel more comfortable lining up and sealing the barrier.
• Keep a spare “change kit” in your bag or car in case you need to change away from home.

Over time, what seems awkward will become a routine you can manage quickly and confidently.

When to Seek Medical Advice

Most pouch changes are straightforward, but certain signs mean you should talk to a healthcare professional right away:

• Heavy bleeding from the stoma or surrounding skin
• Severe pain or swelling around your stoma
• Sudden changes in stoma size or shape
• Signs of infection: excessive redness, warmth, pus, or fever
• Inability to get a good seal despite following all steps

If you’re ever in doubt—or you think something could be serious or life-threatening—please speak to a doctor. You might also consider doing a free, online symptom check, using the doctor approved Ubie Symptom Checker.
