How to Change an Ileostomy Bag: Step-by-Step

Changing an ileostomy bag takes about 10 to 15 minutes once you get the hang of it, and most people change theirs every 3 to 5 days on average. The process involves removing the old pouch, cleaning the skin around your stoma, and applying a fresh pouching system with a secure seal. Whether you’re doing this for the first time after surgery or looking to refine your technique, the steps below walk you through the full process.

Gather Your Supplies First

Having everything within arm’s reach before you start prevents the awkward scramble of searching for supplies with an exposed stoma. You’ll need:

  • New pouch and wafer (or a combined one-piece system)
  • Stoma measuring card and scissors
  • Barrier ring or stoma paste for extra leak protection
  • Skin barrier wipes (alcohol-free)
  • Stoma powder if you have any raw or weepy skin
  • Warm water, mild soap, and a soft washcloth or paper towels
  • A plastic bag for the used pouch
  • Closure clip from your current pouch (save it)

Many people keep a pre-packed kit in the bathroom so everything is ready to go. If you’re away from home, a gallon-size zip-lock bag works well as a portable supply kit.

Remove the Old Pouch

Start by emptying the pouch into the toilet if there’s any output in it. Ileostomy output is liquid to semi-formed, so this step is quicker than you might expect. Remove the closure clip and set it aside for your new pouch.

If you use a two-piece system, press one hand gently on the skin around the stoma to create counter-pressure while peeling the wafer away with the other hand. Pull slowly and downward rather than ripping it off. For a one-piece system, the same technique applies since the pouch and wafer come off together. Place the used pouch in a plastic bag and toss it in the trash. Don’t flush any part of the pouching system.

Clean and Inspect Your Skin

Wash the skin around your stoma with warm water and a soft washcloth or paper towels. A mild soap is fine, but rinse thoroughly. Soaps with oils, moisturizers, or heavy fragrances can leave a residue that prevents the new wafer from sticking properly. The Wound, Ostomy and Continence Nurses Society recommends plain water with a soft material like a paper towel or washcloth as the standard approach. If you use an adhesive remover to get stubborn wafer residue off, wash and dry the skin afterward.

Pat the area completely dry with a clean towel. This is worth being patient about, because even slightly damp skin weakens the adhesive bond.

While the skin is bare, take a moment to look at it. Healthy peristomal skin should look like the skin on the rest of your abdomen. If you notice redness, raw patches, or small raised bumps with a shiny appearance, those are signs of irritation or a possible fungal issue. Ileostomy output contains digestive enzymes that are caustic enough to erode skin quickly if it leaks under the wafer, so catching early irritation matters. Reddened, shiny patches with small satellite bumps around the edges can signal a yeast infection, which is common in the warm, moist environment under a wafer.

Treat Irritated Skin Before Applying the New Wafer

If you spot any raw, weepy, or broken skin, you can still get a good seal. Sprinkle a light dusting of stoma powder on just the irritated area. Then dab a skin barrier wipe over the powder. This “crusting” technique creates a dry, protective layer that the adhesive can grip. Let it air-dry for one to two minutes before moving on. Avoid using tincture of benzoin or other tackifiers, as the WOCN Society advises against them for peristomal skin.

Measure and Cut Your Wafer

Your stoma can change size, especially in the first few months after surgery, so measure it each time you change. Hold the measuring card near your stoma (without touching it) and find the circle that matches. You want a gap of about 1.5 to 3 millimeters between the edge of the cut opening and the stoma itself. Too large a gap exposes skin to digestive output. Too tight risks cutting into or rubbing against the stoma.

Trace the correct circle onto the paper backing of your wafer and cut it out with curved scissors. Run your finger along the cut edge to make sure it’s smooth, since rough edges can irritate the stoma. If you use a pre-cut wafer that matches your stoma size, you can skip this step entirely.

Apply the Barrier Ring or Paste

This step is optional but makes a real difference for leak prevention. You have two main choices: barrier rings and paste. Barrier rings are soft, moldable rings that sit around the stoma opening and fill in any uneven skin contours. They tend to hold up well over several days without dissolving. Paste, which comes in a tube, serves a similar purpose by filling gaps between the wafer and the skin, though some people find it breaks down faster with liquid ileostomy output.

Neither option is universally better. Some people get reliable five-day wear from rings alone, while others prefer paste or a combination. Moldable strips are another option for irregular skin surfaces. If you’re getting frequent leaks, experimenting with a different seal method is often the fix.

Attach the New Pouching System

Peel the paper backing off the wafer. If you use a two-piece system, snap or press the pouch onto the wafer’s flange before or after application, depending on what feels easier. Center the opening over your stoma and press the wafer down, starting from the stoma and working outward to push out air bubbles.

Hold the wafer firmly against your skin for at least 60 seconds. The heat from your hands activates the adhesive and helps it mold to your body’s contours. Some people press with the flat bottom of a toothbrush around the edges for 20 to 30 seconds to reinforce the seal. A warm washcloth held over the wafer for a minute or two can also improve adhesion, especially in cooler weather when the adhesive is stiffer.

Close the bottom of the pouch with the clip or Velcro closure. Give the whole system a gentle tug to confirm it’s secure, then wash your hands.

One-Piece vs. Two-Piece Systems

With a one-piece system, the wafer and pouch are a single unit. Every change means removing the adhesive from your skin, which keeps things simple but means more frequent skin contact with adhesive removal. One-piece systems tend to sit flatter under clothing since there’s no flange ring adding bulk.

A two-piece system lets you swap the pouch without disturbing the wafer. This is helpful if you want to switch between a drainable pouch during the day and a different style at night, or if your skin is sensitive and benefits from fewer full wafer changes. The tradeoff is a slightly bulkier profile from the coupling mechanism. Make sure your pouch and wafer flanges are the same size and brand, since they need to snap together securely.

When and How Often to Change

People with ileostomies wear their pouching system for about 5 days on average, though this varies from 3 to 7 days depending on your skin, body shape, activity level, and the products you use. Change the system on a schedule rather than waiting for a leak. If you’re consistently getting less than 3 days of wear, something in your setup likely needs adjusting, whether that’s the wafer fit, the seal method, or the products themselves.

The best time to change is when output is lowest, which for most people is first thing in the morning before eating or drinking. This gives you a calmer window to work without the stoma being active. Empty your pouch when it reaches about one-third to one-half full. Letting it get heavier than that pulls on the wafer seal, which is one of the most common causes of leaks and premature wear.

Signs Something Needs Attention

Frequent leaks, burning or itching under the wafer, and skin that looks raw or eroded are all signals that your current setup isn’t protecting your skin. Ileostomy output is especially damaging because it contains active digestive enzymes, and even small amounts leaking under the wafer edge can cause painful skin breakdown within hours. If you notice that the skin directly around your stoma is consistently red or excoriated while skin farther away looks normal, the wafer opening is likely cut too large.

Changing the pouch too frequently can also backfire. Repeatedly pulling adhesive off the skin causes mechanical stripping, leaving skin that’s painful, moist, and prone to bleeding. If you’re changing more than every two days because of leaks, the solution is usually a better fit or a different barrier product rather than more frequent changes. A wound, ostomy, and continence (WOC) nurse can evaluate your setup and recommend adjustments. Early intervention with skin problems leads to significantly better outcomes than trying to push through ongoing irritation.
