Ostomy care is the daily routine of maintaining a stoma, a surgically created opening in the abdomen that reroutes waste from the digestive or urinary system into an external pouch worn on the body. It covers everything from changing and emptying the pouching system to protecting the surrounding skin, managing diet, and watching for complications. The specifics vary depending on the type of ostomy you have, but the core skills are the same.
Types of Ostomies
The three main types of ostomies each involve a different part of the body and produce different kinds of output, which directly affects how you manage care.
- Ileostomy: Surgeons bring the ileum, the end of the small intestine, through the abdominal wall. The large intestine is either bypassed or removed entirely. Output tends to be liquid or semi-liquid and more constant, which makes skin protection especially important.
- Colostomy: Part of the large intestine (colon) is brought through the abdominal wall. Because some of the colon is still functioning, output is typically more formed, closer to a normal bowel movement. The farther along the colon the stoma is placed, the firmer the output.
- Urostomy: This type redirects urine rather than stool. Surgeons use a small piece of intestine to create a channel from the kidneys to an opening in the abdomen. The pouch collects urine continuously.
A less common option is a continent ileostomy, where surgeons create an internal pouch from the small intestine with a built-in valve. Instead of wearing an external bag, you drain the internal pouch several times a day by inserting a thin tube through the stoma.
The Pouching System and How It Works
The foundation of ostomy care is the pouching system, a wearable appliance that collects output from the stoma. It has two key parts: a skin barrier (also called a wafer or flange) that adheres to the skin around the stoma, and a pouch that catches waste. These come in two designs. A one-piece system combines the barrier and pouch into a single unit. A two-piece system has a separate barrier that stays on the skin while you snap or click the pouch on and off, which lets you replace the pouch without disturbing the adhesive seal.
Several accessories help the system fit securely and protect your skin:
- Barrier rings: Soft, moldable rings that fill in uneven skin surfaces around the stoma, improving the fit of the skin barrier and helping prevent leakage.
- Stoma paste: Works like caulk, sealing gaps between the stoma and the skin barrier so output can’t seep underneath and reach your skin.
- Skin prep wipes: Apply a thin protective film to the skin before you attach the barrier. These are alcohol-free (“no sting”) and help shield skin from stoma fluid and adhesive removal.
Emptying and Changing the Pouch
You should empty the pouch when it’s about one-third full. Waiting longer adds weight that can pull the seal away from your skin and cause leaks. Depending on your output, this might mean emptying several times a day.
The full pouching system, barrier included, needs to be changed every two to four days. Consistent wear time in that range is a good sign that your system fits well. If you can’t get at least two days of reliable wear before leaking starts, that’s a signal to have your setup evaluated by an ostomy nurse, as the barrier opening, shape, or accessories may need adjusting.
When changing the system, gently remove the old barrier (adhesive remover wipes can help), clean the skin around the stoma with warm water, let it dry completely, and then apply the new barrier and pouch. Avoid using soaps with oils or moisturizers in them, as these can interfere with adhesion.
Protecting the Skin Around the Stoma
The skin immediately surrounding the stoma, called peristomal skin, takes the most abuse. Constant exposure to digestive enzymes or urine causes irritation, and a poorly fitting barrier makes it worse. Healthy peristomal skin should look like the skin on the rest of your abdomen. Any redness, rawness, or itching is worth addressing quickly before it escalates.
The single most important thing you can do is make sure the barrier opening is sized to fit closely around the base of the stoma, with minimal exposed skin between the stoma and the edge of the barrier. Too large a gap lets output pool against your skin. Too tight can injure the stoma itself.
If you develop areas of moisture damage or skin breakdown, a common treatment is dusting the area with skin barrier powder, brushing away the excess, and sealing it with an alcohol-free liquid skin sealant. This creates a dry, protected surface that the barrier can still adhere to. For skin irritation caused by a fungal infection (warm, moist conditions make this possible), antifungal powder applied and sealed the same way is the standard approach. In cases of more significant skin loss, a thin hydrocolloid sheet can be cut to fit around the stoma and used as a protective base layer under the pouching system.
Certain stoma shapes present extra challenges. A stoma that sits flush with the skin or retracts slightly below the surface doesn’t project enough to direct output cleanly into the pouch. A convex skin barrier, which curves inward toward the body, can help push the stoma outward. An ostomy belt adds gentle pressure to improve the seal. If your stoma sits in a deep skin fold or crease, a flexible one-piece system often conforms better than a rigid two-piece.
Diet and Hydration
You don’t need a dramatically restricted diet after ostomy surgery, but a few adjustments make a real difference in comfort and safety. The biggest concern, particularly with an ileostomy, is food blockage. Certain high-fiber and hard-to-digest foods can clump together and obstruct the stoma opening. The most common culprits include nuts, seeds, popcorn, dried fruit, corn, raw pineapple, mushrooms, celery, vegetable and fruit skins, coconut, tough meats like grilled steak, and sausage casings.
You don’t have to avoid these foods entirely. The key is eating small amounts and chewing thoroughly, ideally to an applesauce-like consistency, so pieces pass through the stoma without clumping. Introducing these foods gradually lets you learn how your body handles them.
Hydration matters more after ostomy surgery than most people realize, especially with an ileostomy, because the large intestine (which normally absorbs most of your water) has been bypassed. Aim for at least eight cups of fluid daily, about two liters, and more if you’re in hot weather, sweating, exercising, or producing high output from your stoma. Sip fluids slowly and frequently rather than gulping large amounts at once, as small sips are absorbed more efficiently. During meals, take only small sips to help food go down, then wait about 30 minutes after eating before drinking more freely.
Complications to Watch For
Most stoma complications develop gradually and are manageable when caught early. Three of the most common structural problems are:
- Parastomal hernia: Swelling or a bulge around the stoma, caused by intestine pushing through the abdominal wall near the stoma site. Mild hernias can often be managed with a support belt and guidance from an ostomy nurse. Larger or painful hernias may require surgery.
- Stoma retraction: The stoma pulls back below skin level instead of protruding slightly. This makes it harder to achieve a good seal and increases the risk of skin irritation. Convex barriers and different pouch styles can compensate.
- Stoma prolapse: The opposite problem, where the stoma extends too far above the skin surface. Adjusted pouching systems can accommodate the extra length.
Beyond structural issues, contact your ostomy nurse or doctor if you notice your stoma changing color (it should be pink or red, similar to the inside of your mouth), persistent skin problems that aren’t responding to your usual care routine, signs of blockage like cramping and no output for several hours, or any unusual pain around the stoma site. Most of these situations aren’t emergencies, but early attention prevents them from becoming serious.
Building a Routine
Ostomy care feels overwhelming at first, but it becomes second nature surprisingly quickly. Most people settle into a consistent routine within a few weeks of surgery. Keeping supplies organized helps: barrier rings, paste, powder, skin prep wipes, pre-cut barriers, and spare pouches should all be within reach when you’re doing a change. Many people keep a small travel kit stocked for pouch changes away from home.
An ostomy nurse (also called a wound, ostomy, and continence nurse) is your most valuable resource, especially in the early months. They can evaluate your pouching system fit, recommend accessories for your specific stoma shape and skin contours, and troubleshoot problems like persistent leaking or skin irritation. If you’re struggling with wear time, frequent leaks, or skin breakdown, a single visit can often identify the issue and save weeks of frustration.
