TL; DR
- Healthy appearance: A normal stoma is dark pink to bright red, moist and shiny, and protrudes 1-3 cm above the skin surface
- Post-surgery changes: Stomas look swollen and puffy immediately after surgery but shrink and stabilize over several weeks as healing progresses
- Self-care routine: Check color, moisture, size, protrusion height, and surrounding skin health during each pouch change to catch issues early
- Warning signs: Contact your healthcare provider for color changes (pale, purple, gray, black), excessive bleeding, sudden size changes, persistent skin problems, or continuous leakage
Introduction
Many people feel surprised or concerned when first seeing their stoma, so uncertainty and emotional adjustment are perfectly normal. Learning what a healthy stoma looks like helps alleviate some of the fear and builds reassurance over time. This is why as you get used to its appearance, size, and normal changes, confidence grows, and daily care feels manageable.
The first time you see a stoma, or work with one, you may feel odd, overwhelmed, or even scared. This blog describes what a stoma is, what a stoma looks like, what may happen as a stoma ages, and signs that a stoma may need medical attention.
What Is A Stoma?
A stoma is a surgically made opening located on the surface of the abdomen that joins a portion of the bowel or urinary system directly to the exterior of the body. The opening is created because a person may need to eliminate their body wastes, either from the bowel or the bladder, through a different pathway.
You may also hear the term ostomy, which refers to the surgical procedure itself. Depending on the type of surgery, a stoma may allow the passage of:
- Stool, in the case of a colostomy or ileostomy.
- Urine, in the case of a urostomy.
- Mucus, which is especially common in the early healing period.
A stoma is made from living tissue that was previously inside your body. Because of this, it does not look or behave like normal skin, and that difference is completely normal and expected.
Color & Texture: How a Healthy Stoma Looks Like
One of the most important indicators of stoma appearance in health is its color and texture. While its appearance may be surprising at first, understanding normal stoma color and size can be reassuring.
Color
A healthy stoma is:
- Dark pink to bright red
- Evenly colored across its surface
- Vibrant and well-perfused
This coloration indicates good blood flow. In fact, a healthy stoma closely resembles the inside of your mouth or lips.
Texture & Moisture
- The surface should be moist, shiny, and glossy
- The tissue should feel soft and pliable
- It should never appear dry, crusted, or hardened
Because the stoma lacks nerve endings like skin, gentle touch should not cause pain.
Minor Bleeding
It is common for a stoma to bleed slightly during cleaning or pouch changes. However, you should notify your healthcare provider right away if bleeding seems excessive or occurs on its own.
Shape & Protrusion: Why Height Matters
A life with a stoma requires an understanding of what a stoma looks like. Recognize what a normal stoma looks and feels like to detect potential issues, as every stoma is different.
Stoma Shape
No two stoma are exactly alike in shape and appearance. But specific patterns are considered normal.
Most stomas are:
- Smooth, round, or oval: These have a soft, rounded, or slightly elongated oval form.
- Slightly irregular outline: It is perfectly normal for a margin to exhibit a slight irregularity in outline.
- Moist and shiny: Healthy mucous membranes, such as the inside of your mouth, are moist and shiny.
Small changes are normal. There are variations in stoma appearance depending on the type of surgery (colostomy, ileostomy, or urostomy), the surgeon, and the particular anatomy.
Protrusion: The “Height” of Your Stoma
How much your stoma protrudes from the skin's surface will affect the adherence of your pouch directly, and how waste is directed away from your body efficiently.
Ideal protrusion: About 1–3 centimeters above the skin surface. Ideally, proper positioning ensures a direct flow of feces or urine into the pouch.
Why height matters: Poor positioning of the stoma, too close to the skin surface, or prolapsing below the skin allows drainage to accumulate at the base, hence making the adhesion of the ostomy baseplate or barrier not as effective. Leaks can result in redness, irritation, and infection.
Other Presentations:
- Flush stomas
- Sit on the same level as your skin.
- It often occurs when the stoma cannot be brought further out due to scar tissue or body contour.
- They can work well but often need convex pouching systems that push against them gently in order to improve fit and drainage.
- Retracted stomas
- Sit slightly below the skin level.
- It can result from tension on the bowel, weight changes, or post-surgical healing.
- May need custom barriers or belts for better seal and protection.
- Prolapsed stomas
- Extend outward more than the usual 3 cm.
- Though their appearance may seem alarming, they often remain functional.
- Gentle support garments and specific pouching techniques can help manage them, but it’s important to consult a stoma care nurse for guidance.
Surrounding Skin & Overall Appearance
The skin surrounding the stoma, typically about four inches, is known as the peristomal skin. It is very important for your comfort and hygiene. A healthy peristomal skin area serves as a sound foundation that prevents irritation, leakage and infection.
What healthy peristomal skin looks like:
- Intact, smooth, and without open areas.
- Same color and texture as normal abdominal skin.
- Pain-free, non-itchy, and free from redness or swelling.

Common Skin Issues and Their Causes
Peristomal skin problems are common but easily preventable once the cause is identified. Minor discomfort or redness often points to a correctable issue:
Poorly fitting pouch openings:
- A hole that is too large or too small allows the output to come into contact with the skin.
Leakage of Stool/Urine:
- Chemical irritation from the leakage of stool or urine under the barrier.
- Sensitivity to adhesive tape may cause skin irritation, redness, or itching around the area where the pouch is applied.
- Improper cleaning or removal methods: Aggressive scrubbing may damage fragile skin.
Symptoms may include:
- Burning, stinging, or redness.
- Small skin sores or lacerations.
Many problems can be resolved before becoming serious, but only if persistent itching or pain is noticed early and referred to a stoma care professional.
How Stoma Changes Over Time
Remember, your stoma is part of your body, and it will evolve as you recover. Learning to identify these phases will therefore enable you to remain calm, confident, and proactive.
Immediately After Surgery:
- The stoma looks puffy, wet, and purplish-red.
- Uneven shape; mucus secretion is normal.
- It can feel tender or slightly sore.
- This dilatation, termed edema, is a normal reaction to surgery and typically resolves over a few weeks.
Weeks Following Surgery:
- Swelling disappears as the healing progresses.
- The stoma looks smaller and more stable in size.
- The color transitions to a steady pink-to-red hue.
- The protrusion becomes more defined.
During this phase, you may have to adjust the opening of your pouch to match the development of your stoma. Prior to every adjustment, it is essential to measure for a proper fit.
Actual Appearance
Once fully healed, the mature stoma should:
- Preserve a stable shape and dimensions.
- Stay moist, shiny, and comfortably jutting out.
- Can take strong and secure pouch adhesion.
- Monitoring can also prevent unforeseen changes from occurring and becoming complicated if left unnoticed.
How to Self-Assess Your Stoma
Regular self-evaluation helps you take control of your stoma care routine and ensure good long-term health. Taking a few moments to evaluate each time you change your stoma pouch can be very helpful. The most crucial points to check include:
- Color & Moisture: A normal stoma is pink to red in color and moist.
- Size & Shape: You should measure your stoma periodically, as size variations are likely. Download a free stoma measuring guide.
- Protrusion: Ensure it is elevated 1–3 cm from the skin surface.
- Surrounding Skin: Evaluate the skin around the stoma for being of normal color and smooth to touch without redness.
- Monitor stool texture, urine clarity, or mucus amounts.
- Changes Over Time: Monitor for swelling, bleeding, odor, and irritation using a journal.
- These are meant to help detect early signs and boost your confidence in managing your ostomy on your own.
When to Report Something
Even when taking good care, unexpected changes may occur. You can contact your stoma nurse or doctor if you notice any of the following:
- Color may shift to light, purple, grey, or black (indication of problems with circulation).
- Sudden retraction or prolapse.
- Bleeding or Swelling.
- Unusual discharge, odor, or pain.
- Continuous redness or raw areas.
- Open sores or injured skin in the area. Repeated leakage, even when correctly fitted. Medical attention can prevent infection, restore comfort, and preserve skin integrity.
Final Takeaway
A normal stoma appears pink to reddish in color, moist and shiny, projecting above the surface of the skin by 1-3 cm. By practicing self-care, properly handling the ostomy bag, including a Coloplast Stoma Bag, and seeking prompt attention from doctors and specialists when needed, it is possible to live freely and unafraid of having a stoma.
Life with an ostomy, therefore, is not a disability but an adaptation that supports health, preserves dignity, and enhances overall quality of life.
