Living with an ostomy brings unique daily routines, and keeping the skin around your stoma healthy is one of the most important parts of your self-care. The skin surrounding a stoma is called the peristomal skin. When this area becomes red, itchy, or sore, it can make managing your ostomy challenging and uncomfortable. Fortunately, preventing and treating peristomal skin irritation is highly manageable with the right routine, proper supplies, and a little patience. By understanding how to protect this sensitive area, you can live comfortably, confidently, and worry-free.
Understanding Peristomal Skin and Why Irritation Happens
According to the United Ostomy Associations of America (UOAA), healthy peristomal skin should look exactly like the skin on the rest of your abdomen. It should be smooth, intact, and free of discoloration. However, because this skin is constantly covered by an adhesive barrier and exposed to bodily waste, it is highly vulnerable to damage.
To understand how to protect this area, it helps to understand a few basic terms:
- Stoma: The surgically created opening on your abdomen that allows bodily waste (urine or stool) to exit your body.
- Peristomal skin: The area of skin immediately surrounding the stoma, typically extending two to three inches outward. This is where your ostomy wafer sticks.
- Peristomal Medical Adhesive-Related Skin Injury (MARSI): A clinical term used by the Wound, Ostomy, and Continence Nurses Society (WOCN) to describe skin damage, such as tearing or redness, caused by the frequent application and removal of medical adhesives.
Peristomal skin irritation is usually caused by one of three things: chemical contact, mechanical trauma, or moisture buildup. Chemical irritation occurs when urine or stool leaks underneath your ostomy wafer and sits directly on your skin. Because digestive enzymes and waste are highly acidic or alkaline, they can quickly erode the skin, causing a painful, red rash. Mechanical irritation happens when the adhesive wafer is pulled off too quickly, stripping away the top layers of healthy skin. Moisture-related irritation occurs when sweat or liquid is trapped beneath the barrier, leading to a fungal infection or skin breakdown.
The Essential Role of Skin Barriers
The foundation of any successful ostomy care routine is the skin barrier. Also known as a wafer or faceplate, the barrier sticks directly to your abdomen, holding your ostomy pouch in place while shielding your skin from corrosive body waste. Choosing the right skin barriers is critical to maintaining skin integrity.
There are two primary types of skin barriers:
- Flat barriers: Best for stomas that protrude slightly above the abdomen. They lie flat against the skin and are highly flexible.
- Convex barriers: These have a curved, outward shape. They are designed for stomas that are flush with the skin or retracted (pulled inward). The gentle pressure of a convex barrier helps push the stoma forward, directing waste straight into the pouch and preventing leaks.
Additionally, barriers come in "cut-to-fit" styles, which allow you to trim the opening to your exact stoma shape, and "pre-cut" styles, which are pre-sized for round, stable stomas. Using the correct barrier style and size is your first and best line of defense against leaks and irritation.
Step-by-Step Guide to Preventing and Treating Peristomal Skin Irritation
Establishing a consistent, gentle routine for your pouch changes is the most effective way to keep your skin healthy. Follow these step-by-step instructions at home to protect your skin during every change.
Phase 1: Gather Your Supplies
Before you begin, make sure you have all your supplies within arm's reach. This prevents you from having to move around mid-change, which can lead to accidental leaks. You will need:
- A new ostomy pouch and skin barrier
- An adhesive remover wipe or spray (optional, but highly recommended)
- Warm water and a clean washcloth (or soft paper towels)
- A stoma measuring guide and a pen
- Curved medical scissors (if using a cut-to-fit barrier)
- Stoma powder (only if your skin is raw or weeping)
- A waste bag for disposal
Phase 2: Step-by-Step Instructions
Step 1: Gently Remove the Old Pouching System
Never rip or tear your ostomy barrier off your skin. According to the WOCN, fast removal is a leading cause of skin stripping. Instead, use an adhesive remover wipe or spray to gently dissolve the seal. Press down on the skin of your abdomen with one hand while slowly peeling the barrier downward with the other. Work from the top of the barrier to the bottom, moving slowly and gently.
Step 2: Clean the Peristomal Skin
Clean the skin around your stoma using warm water and a clean washcloth or soft paper towel. You do not need soap to clean this area. If you prefer to use soap, choose a mild, fragrance-free option that does not contain oils, moisturizers, or deodorants. Regular bath soaps often leave behind a greasy residue that prevents your new skin barrier from sticking properly, which can lead to early leaks.
Step 3: Inspect Your Skin and Stoma
Take a moment to look closely at your skin. Note any redness, rash, or irritation. If you see redness that matches the exact shape of your barrier, you may be sensitive to the adhesive. If the redness is concentrated right around the stoma, it is likely a sign that waste is leaking onto your skin. Check the color of your stoma as well; it should always be a healthy, moist red or pink, similar to the inside of your mouth.
Step 4: Measure Your Stoma
Stomas can change in size and shape over time, especially during the first six to eight weeks after surgery or if your weight fluctuates. Use your stoma measuring card to find the correct size. The opening of your skin barrier should fit snugly around the base of the stoma, leaving only about a 1/16 to 1/8-inch gap. If the gap is too large, your skin will be exposed to waste. If it is too small, the barrier can cut into or bruise the stoma.
Step 5: Treat Irritated Skin (The "Crusting" Method)
If your peristomal skin is red, raw, or weeping, your new barrier will not stick well. To treat this, use the "crusting" technique recommended by ostomy clinicians:
- Dust a small amount of stoma powder over the raw, wet areas of skin.
- Gently brush away any excess powder so only a thin layer remains on the irritated spots.
- Dab a non-alcohol skin barrier prep spray or wipe over the powder. This seals the powder and creates a dry, smooth surface.
- Allow the area to dry completely before applying your new barrier.
Step 6: Prepare and Apply the Skin Barrier
If using a cut-to-fit barrier, trace your stoma size onto the back of the wafer and cut it out carefully, smoothing the edges with your finger. Warm the skin barrier between your hands for a minute or two before applying it. The warmth of your body activates the adhesive, helping it mold to your skin's natural contours. Center the barrier over your stoma, press down gently, and hold your hand over the barrier for 30 to 60 seconds to ensure a secure, complete seal.
Common Mistakes to Avoid
When managing an ostomy, small habits can make a big difference in skin health. Avoid these common mistakes to protect your skin:
- Using household skin products: Avoid using baby wipes, rubbing alcohol, hydrogen peroxide, or standard body lotions on your peristomal skin. These products contain chemicals, oils, and alcohol that can damage the skin or prevent your barrier from adhering.
- Waiting too long to change a leaking pouch: If you feel burning, itching, or wetness under your barrier, do not wait for your scheduled change day. A burning sensation is a sign that waste is actively irritating your skin. Change your pouch immediately to stop the damage.
- Overusing skin prep products: Unless your skin is raw and you are using the crusting method, you generally do not need skin prep wipes. Overusing them can build up layers on the skin, actually reducing the stickiness of your barrier.
When to Consult a Healthcare Professional
While minor redness can often be resolved with proper sizing and the crusting method, some skin issues require professional medical attention. Contact your Wound, Ostomy, and Continence (WOC) nurse or primary healthcare provider if you experience any of the following:
- The peristomal skin is severely raw, bleeding, weeping, or blistered.
- You notice a bright red, itchy rash with small bumps, which may indicate a fungal (yeast) infection requiring prescription treatment.
- Your stoma changes color, becoming pale, dark red, purple, blue, or black. This is a medical emergency that requires immediate care.
- You experience severe, persistent pain or burning around your stoma.
- Your pouching system is leaking constantly (more than once or twice a week), which suggests you may need a different type of barrier, such as a convex wafer or a different size.
What does healthy peristomal skin look like?
According to the National Institutes of Health (NIH), healthy peristomal skin should look exactly like the skin on the rest of your abdomen. It should not be red, swollen, itchy, painful, or warm to the touch. It should feel comfortable and remain intact when you remove your pouching system.
Can I use regular soap to clean the skin around my stoma?
It is best to clean the skin around your stoma with warm water only. If you prefer to use soap, choose a very mild, fragrance-free soap that does not contain oils, moisturizers, or deodorants. Avoid standard bath soaps and body washes, as they leave behind a residue that can prevent your skin barrier from sticking properly, leading to leaks.
What should I do if my peristomal skin is red and weeping?
If your skin is raw and weeping, you can use the "crusting" method. Clean and dry the skin, apply a light dusting of stoma powder, brush off the excess, and seal it with a non-alcohol skin barrier spray or wipe. Let it dry completely before applying your new skin barrier. If the redness does not improve within a few days, consult your ostomy nurse.
How often should I change my ostomy skin barrier?
On average, ostomy skin barriers are designed to be changed every 3 to 7 days, depending on your body type, activity level, and the type of ostomy you have. However, if you feel any itching, burning, or suspect a leak, you should change your barrier immediately to prevent skin damage.
