Ostomy care is the daily practice of managing a stoma and its pouching system after surgery that reroutes part of the intestine or urinary tract through an opening in the abdomen. It involves emptying or changing a collection pouch, keeping the surrounding skin healthy, and adjusting to a routine that, for many people, becomes second nature within a few months. The basics are straightforward, but the details matter more than most people expect, particularly when it comes to protecting the skin around the stoma and choosing the right equipment for your body.
Why Someone Gets a Stoma
A stoma is created when a surgeon brings a loop or end of the intestine (or, less commonly, the ureter) to the surface of the abdomen and stitches it in place. The result is a small, pink, moist opening through which waste exits the body into an external pouch instead of following the usual route. The tissue looks similar to the inside of your cheek, and it has no nerve endings for sharp pain, though you can feel pressure.
The reasons for stoma surgery span a wide range of conditions. Colorectal cancers and inflammatory bowel diseases like Crohn’s disease and ulcerative colitis are among the most recognized causes, but traumatic abdominal injuries and bowel obstructions also lead to stoma creation. A study of over 200 ostomy patients found that gangrenous sigmoid volvulus, colorectal cancers, and abdominal injuries were the three leading indications, together accounting for about 80% of cases in that population.1PubMed Central. Types and Indications of Colostomy and Determinants of Outcomes of Patients After Surgery The relative frequency of each cause varies widely between countries and healthcare settings.
The three main types of stoma are a colostomy (from the colon), an ileostomy (from the small intestine), and a urostomy (from the urinary tract). The type you have shapes almost everything about daily care, from how often you empty the pouch to how much fluid your body loses to what skin problems you are most likely to face.
How the Pouching System Works
The pouch that collects waste is only the most visible part of a multi-component system. At its core, every ostomy appliance has two elements: a skin barrier (also called a baseplate or wafer) that adheres to the abdomen around the stoma, and a pouch that attaches to or is built into that barrier. One-piece systems combine them; two-piece systems let you snap or click the pouch on and off without disturbing the barrier stuck to your skin.
The skin barrier is the component that does the heaviest lifting. Most are made from hydrocolloid adhesives, a blend of materials designed to absorb moisture while maintaining a seal against the skin. Research into these adhesives is ongoing, with work focused on improving how long the seal holds up and how well the barrier handles the corrosive fluids that ileostomies produce.2London South Bank University Research Repository. Maintaining the Integrity Over Wear Time of a Hydrocolloid-based Ostomy Adhesive Whilst Maintaining Skin Barrier Function A barrier that breaks down too quickly lets output seep underneath, irritating the skin and undermining the seal further in a frustrating cycle.
Not every abdomen is flat and smooth around the stoma. Creases, folds, scars, and stomas that sit flush with or below the skin surface can make it hard for a flat barrier to form a tight seal. In those cases, convex pouching products, which press gently inward around the stoma to push it outward, are frequently the preferred solution.3PubMed Central. Use of Convexity in Ostomy Care: Results of an International Consensus Meeting Getting the right fit often takes trial and error, and a wound or ostomy care nurse is the best resource for that process.
Researchers have also explored lower-cost alternatives for regions where commercial pouching systems are too expensive. A proof-of-concept study tested a beeswax and pine resin adhesive mixture, sourced both in the United States and in Tanzania, and found it performed comparably to a commercial adhesive in dermatological safety testing.4PubMed. Dermatological Effects of a Beeswax-Pine Resin Mixture on Abdominal Skin: A Proof-of-Concept Study Supporting the Development of an Affordable Investigational Ostomy Pouching System in Low-Income Regions That kind of innovation matters because the cost of supplies is a serious barrier to adequate ostomy care in much of the world.
The Daily Routine
Day-to-day ostomy care centers on emptying the pouch, changing it when needed, and cleaning the skin around the stoma. How often you empty depends on your stoma type. Colostomy output is usually semi-formed and may only need emptying a couple of times a day. Ileostomy output is more liquid and frequent, often requiring emptying four to six times daily. Urostomy pouches have a drain valve at the bottom and need regular draining as well.
Pouch changes, meaning removing the entire barrier from the skin and applying a fresh one, typically happen every three to five days for most systems, though this varies by product, body type, and output consistency. During each change, cleaning the peristomal skin is a crucial step. The prevailing expert guidance is remarkably simple: use water. A survey of wound and ostomy care nurses found that about 80% instructed their patients to use only water for routine cleansing of the skin around the stoma, advising against soap because residue can interfere with how well the new barrier adheres.5PubMed Central. Current Ostomy Care Practice Related to Peristomal Skin Issues
An international expert group recently developed a standardized protocol for peristomal hygiene, built around four steps: Cleanse, Assess, Secure, and Live. The framework covers safe adhesive removal and skin cleaning, a repeatable assessment of the skin and stoma using validated tools, individualized product selection to match your anatomy and risk factors, and ongoing support for adapting to daily life.6PubMed. Standardizing Peristomal Hygiene: Reducing Variation and Complications in Ostomy Care The protocol is designed to work whether you are working with a specialist nurse or managing care largely on your own.7Journal of Wound, Ostomy, and Continence Nursing. Peristomal Hygiene: A Protocol of Care to Address a Global Crisis in Ostomy Care
The Skin Problem Almost Everyone Faces
Peristomal skin complications are the single most common issue in ostomy care, and their frequency is striking. A systematic review found that reported rates range from about 36% to over 73% of ostomy patients, depending on the study and the population.8PubMed Central. Peristomal Skin Complications in Ileostomy and Colostomy Patients: What We Need to Know from a Public Health Perspective That means skin problems are not a rare complication but something the majority of ostomates will deal with at some point.
The most common type is contact dermatitis, essentially irritation caused by stoma output or adhesive products touching the skin. Moisture-associated skin damage and maceration (where the skin stays wet and begins to break down) are also frequently reported.8PubMed Central. Peristomal Skin Complications in Ileostomy and Colostomy Patients: What We Need to Know from a Public Health Perspective Mechanical trauma from repeatedly pulling off adhesive barriers rounds out the list. Skin infections such as fungal overgrowth or folliculitis can also occur but are less common.
Certain factors make skin problems more likely. An analysis of trial data found that people with skin creases in the peristomal area were roughly three times more likely to develop a complication than those with smooth skin surfaces. The likelihood also increased by about a quarter for every additional week a person had their stoma, suggesting that cumulative exposure matters. Perhaps most strikingly, ileostomy patients were approximately ten times more likely to develop a severe skin complication compared to colostomy patients, because ileostomy output contains more digestive enzymes that aggressively break down skin.9Journal of Wound, Ostomy, and Continence Nursing. Lessons Learned About Peristomal Skin Complications: Secondary Analysis of the ADVOCATE Trial The three most commonly used products to manage skin trouble were barrier rings, skin barrier powder, and adhesive remover.
Parastomal Hernia and Other Structural Complications
Beyond skin issues, the other major physical complication is parastomal hernia, where abdominal contents bulge through the muscle wall around the stoma site. This is more common than many patients are warned about. One study found parastomal hernias in about half of loop stoma patients during follow-up, with roughly equal numbers detected by physical examination and by CT scan alone.10PubMed Central. Risk factors for parastomal hernia of loop stoma and relationships with other stoma complications in laparoscopic surgery era Another study tracking patients over a median of three years found that about 30% developed a parastomal hernia, with female sex, age over 60, higher body mass index, and hypertension all emerging as independent risk factors.11Annals of Coloproctology. Incidence and Risk Factors of Parastomal Hernia
End colostomies carry the highest hernia risk compared to other stoma types. European Hernia Society guidelines strongly recommend using a prophylactic synthetic mesh at the time of end colostomy creation to reduce the chance of hernia formation.12PubMed. European Hernia Society guidelines on prevention and treatment of parastomal hernias Peristomal skin disorders and parastomal hernias also appear to be linked, with the presence of one making the other more likely, which makes sense because a hernia changes the abdominal contour and makes it harder for the pouching system to seal properly.10PubMed Central. Risk factors for parastomal hernia of loop stoma and relationships with other stoma complications in laparoscopic surgery era
Fear of hernia also affects exercise. A survey of Australians living with a stoma found that roughly half reported a parastomal hernia, and those with a hernia were far less likely to have received guidance about exercise. Fear of vigorous activity, abdominal exercises, and heavy lifting was high regardless of hernia status, and fewer than a quarter of all participants completed strengthening or vigorous exercise regularly. The reluctance is understandable, but inactivity carries its own health costs, and guided exercise programs tailored to ostomates are an underused resource.
Diet and Hydration After an Ileostomy
Dietary considerations differ sharply between colostomy and ileostomy patients. With a colostomy, the large intestine still absorbs water before output reaches the stoma, so dehydration is less of a concern and dietary restrictions are relatively mild. With an ileostomy, the colon has been bypassed or removed entirely, and the body loses a significant amount of water and electrolytes through liquid stool output.
Dehydration is a leading cause of hospital readmission after ileostomy surgery, and the risk of kidney injury rises substantially.13PubMed Central. Oral rehydration solution for the management of fluid and electrolyte disturbances in patients with an ileostomy: A scoping review Oral rehydration solutions, which contain a balance of sodium, potassium, and glucose, help the remaining small intestine absorb water more effectively than plain water alone. Many ileostomy patients are advised to sip a rehydration solution throughout the day rather than relying solely on drinking water or other beverages.
High-output ileostomies, where the stoma produces more than about 1,500 milliliters per day, require especially careful dietary management. General guidance includes eating smaller, more frequent meals, chewing food thoroughly, and being cautious with high-fiber or hard-to-digest foods that could cause blockages. Staying on top of sodium and fluid intake is not optional for this group; it is the difference between staying out of the hospital and ending up in the emergency department.
Emotional and Social Impact
The psychological dimension of living with a stoma is substantial and frequently underestimated by healthcare providers focused on the surgical and physical aspects of care. A review of the literature identified poor body image perception, depression, sexual difficulties, and lower psychosocial adaptation as the most commonly reported problems among stoma patients.14PubMed Central. Overview of psychosocial problems in individuals with stoma: A review of literature
Body image disturbance appears to be closely tied to other psychological outcomes. In one study, patients who reported depressive thoughts or self-harm ideation soon after surgery had significantly higher body image disturbance scores. Those with higher self-efficacy, meaning confidence in their own ability to manage their stoma, had lower body image disturbance.15PubMed Central. Psychological Adaptation to Alteration of Body Image among Stoma Patients: A Descriptive Study That finding points to a practical lever: building confidence in self-care does not just improve pouch changes, it seems to genuinely help with how you feel about your body.
Sexual function and intimacy deserve direct mention because they are commonly affected yet rarely discussed proactively. The surgery that creates a stoma can damage pelvic nerves, and many cancer patients have also undergone radiation or chemotherapy that compounds the physical effects. Beyond the physiological side, the psychological impact of having a visible pouch during intimacy creates anxiety for many people.16PubMed Central. Sexual Dysfunction and Intimacy for Ostomates Qualitative research with stoma patients has found that changes in spousal relationships and unmet needs for sexual health information are recurring themes.17PubMed Central. The sexuality experience of stoma patients: a meta-ethnography of qualitative research Smaller pouches, pouch covers, and intimacy wraps exist, and openly discussing concerns with a partner and a healthcare provider is consistently recommended as the most effective first step.
When a Stoma Can Be Reversed
Not all stomas are permanent. Many are created as temporary measures, particularly loop ileostomies formed to protect a surgical connection further downstream while it heals. Reversal surgery reconnects the intestine and closes the abdominal opening. However, timing matters considerably.
A multi-center study found that patients who had their stoma reversed within 18 months had significantly fewer major complications compared to those who waited longer. The early-reversal group also had shorter hospital stays and a much lower rate of post-operative bowel paralysis.18PubMed Central. Stoma reversal after emergency stoma formation—the importance of timing: a multi-centre retrospective cohort study Being male and undergoing chemotherapy for cancer were both associated with longer waits before reversal, suggesting that systemic treatment and possibly delayed surgical scheduling contribute to timing delays.
Reversal surgery itself carries risks. In a study of nearly 400 patients undergoing temporary stoma reversal, the most common early complication was surgical site infection, affecting about a quarter of patients. Wound breakdown, small bowel obstruction, and anastomotic leak (where the new intestinal connection fails to seal properly) were less common but potentially serious.19Biological and Clinical Sciences Research Journal. Early Postoperative Outcomes of Temporary Intestinal Stoma Reversal Surgery Reversal is not a simple undo button, but for patients whose underlying condition has resolved, it is a realistic goal.
Technology Changing the Routine
Ostomy care has traditionally been a low-tech affair: pouch, barrier, scissors, and mirror. That is changing. A systematic review of health technologies in ostomy care found two broad categories emerging: sensor-based wearable devices, mostly used to track pouch fullness and output volume, and app-based platforms on phones or tablets used for patient education and self-management. The review found that both categories improved patients’ knowledge, self-care participation, and sense of control over their condition.20Journal of Wound, Ostomy, and Continence Nursing. A Systematic Review of Health Technologies Impact on Ostomy Care
One clinical trial of a digital ostomy device that monitors the pouch found that after 12 weeks of use, leakage episodes decreased significantly. Patients also reported less embarrassment, more social engagement, and better self-management scores.21medRxiv. Evaluation of a novel digital ostomy device on leakage incidents, quality of life, mental well-being, and patient self-care: an interventional, multicentre clinical trial A separate pilot of an intelligent monitoring system using deep learning and augmented reality reported reductions in complication rates, improvements in health literacy, and lower hospital readmission rates within three months after surgery.22PubMed Central. Intelligent monitoring system for quality of life of colostomy patients based on deep learning and AR These are early-stage findings and the evidence base is still small, but the direction is clear: connected devices that alert you before a leak happens or that help you track patterns in your output could meaningfully reduce the daily anxiety that living with a stoma creates.
Ostomy Care in Children
Pediatric stomas present their own set of challenges. Children may need a stoma for congenital conditions like Hirschsprung disease or imperforate anus, and the physical realities are different from adult care: smaller bodies, faster growth requiring frequent appliance adjustments, and skin that reacts differently. Parents and caregivers are the ones performing the care, and studies have shown that insufficient pre- and post-operative education is a major contributor to complications. One report noted that roughly 73% of ostomy patients with inadequate preparation reported skin-related problems.23Dove Press. Empowering Stoma Care: Enhancing Knowledge, Confidence, and Support Through Collaborative Approaches Between Doctors and Parental Communities for Children with Stomas Collaborative approaches between medical teams and parent communities have shown promise in improving knowledge and confidence, which in turn reduces the physical and emotional toll on both the child and the family.
Access and Affordability Around the World
In high-income countries, ostomy supplies are typically covered by insurance or national health systems, and specialized wound and ostomy care nurses are available to guide patients. That is not the reality for much of the world. A mixed-methods study across four low- and middle-income countries highlighted the stark challenges: patients and caregivers lacked basic knowledge about stoma care, access to specialized nursing was minimal, and the cost of commercial pouching supplies was prohibitive for many families.24Journal of Global Health Reports. Mixed-methods exploration of challenges to stoma care for ostomates in four low-and middle-income countries: STomacARe For Improvement reSearcH (STARFISH) study
In settings where a single ostomy pouch can cost more than a day’s wages, patients sometimes resort to improvised collection systems, reuse disposable equipment far beyond its intended lifespan, or avoid leaving home entirely. The gap in stoma counseling is just as damaging as the supply gap: without hands-on instruction, people do not learn how to size a barrier correctly, how to recognize early skin breakdown, or when to seek medical help. Addressing these disparities requires cheaper products, more trained providers, and health systems that recognize ostomy care as an ongoing need rather than a one-time surgical outcome.
