A prolapsed stoma looks like the stoma has telescoped outward, sticking out much further from the body than usual. Instead of the typical small, round bud sitting close to the skin, a prolapsed stoma appears as a longer, more cylindrical segment of exposed bowel protruding through the opening in the abdomen. It often looks swollen and may change in size throughout the day, particularly with standing, coughing, or physical activity.
How a Prolapse Differs From a Normal Stoma
A healthy stoma typically protrudes about 1 to 3 centimeters above the skin surface. It should be moist, shiny, and a pink-to-red color similar to the inside of your cheek. A prolapsed stoma keeps that same moist, glistening tissue appearance but extends significantly further out. Some prolapses add just a couple of centimeters, while others can extend several inches beyond where the stoma normally sits.
The protruding bowel often looks thicker and puffier than the original stoma because the tissue tends to swell once it’s outside the body. The surface may appear slightly more wrinkled or folded as the intestinal lining bunches during the protrusion. The shape can shift from the usual round bud to something more elongated or sausage-like.
Color Changes and What They Mean
Color is the single most important thing to watch. A prolapsed stoma that remains its normal healthy pink or red is generally not dangerous. The tissue is still getting adequate blood flow, and while the appearance can be alarming, a pink prolapse that continues to function is typically managed without urgency.
The colors that signal trouble are dusky purple, dark blue, or black. These changes indicate the blood supply to the protruding bowel is being compromised. A stoma that turns dusky or dark may be developing ischemia, where the tissue is being starved of oxygen. If the tissue turns black, necrosis (tissue death) may already be occurring. This can develop within hours and requires immediate medical attention. Ulceration on the stoma surface, bleeding that doesn’t stop, or a stoma that stops producing output altogether are also warning signs.
Why Prolapse Happens
A stoma prolapse occurs when a section of bowel pushes further through the opening in the abdominal wall than it should. Think of it like a sleeve being pushed inside out through a hole. The bowel essentially slides forward through the surgically created opening, often because the muscles and tissue around that opening aren’t providing enough resistance to keep it in place.
Loop stomas, where a loop of bowel is brought to the surface rather than a single cut end, are far more prone to prolapse. Rates for loop colostomies can reach as high as 47%, while end stomas and ileostomies have much lower rates, sometimes as low as 2%. Transverse loop colostomies carry the highest risk because of the larger amount of mobile bowel available to slide through the opening.
Being overweight is a significant risk factor. One study found that people with a BMI of 25 or higher had roughly 8.7 times the odds of developing a prolapse after loop colostomy compared to those at a lower weight. The thickness of the abdominal muscle wall where the stoma passes through also matters. When the stoma is routed through a thinner section of muscle, the risk increases by a similar magnitude. The likelihood of prolapse also increases over time, so a stoma that looks stable in the first few months can still prolapse years later.
How Prolapse Changes Throughout the Day
One of the most distinctive features of a prolapsed stoma is that it often changes size. Many people notice the prolapse is worse when they’re standing, straining, or coughing, and it may partially retract when they’re lying down and relaxed. This is because increased pressure inside the abdomen pushes more bowel outward. You might find that the stoma looks relatively normal in the morning and progressively extends as the day goes on, especially with physical activity.
Managing a Prolapse at Home
If a prolapse happens and the stoma remains pink and functional, the first approach is gentle manual reduction. This means lying down in a relaxed position and carefully pushing the protruding bowel back through the opening using steady, gentle pressure. Cold compresses can sometimes help reduce swelling enough to make this easier.
When swelling prevents the bowel from being pushed back in, a technique using ordinary granulated sugar can help. Applying sugar directly to the swollen stoma tissue draws fluid out of the bowel wall through osmosis, reducing the swelling enough to attempt reduction again. In published case reports, this approach has succeeded after initial manual attempts failed. The sugar acts as a desiccant, pulling water from the puffy tissue and shrinking the bowel’s diameter. If this doesn’t work, or if the stoma shows any color changes toward purple or black, you need emergency medical care before the tissue loses its blood supply permanently.
Adjusting Your Pouching System
Living with a prolapsed stoma often means rethinking your ostomy supplies. The extra length and changing size of the stoma can break the seal on a standard pouching system, leading to leaks and skin irritation. A flexible, cut-to-fit skin barrier works better than a pre-cut one because you can adjust the opening size as the stoma changes throughout the day. Switching to a larger pouch may also help accommodate the extra tissue without putting pressure on it.
Support belts designed for ostomies can make a meaningful difference. Hernia-style support belts are elastic binders with an opening for the pouch that stabilize the area around the stoma, helping reduce protrusion and keeping the pouching system sealed more securely. Research suggests that wearing an ostomy support garment reduces leakage frequency, which in turn protects the surrounding skin from irritation. Some newer belt designs include a compartment that holds and supports the pouch against the body, distributing its weight so the adhesive seal isn’t pulled by gravity. People who use these garments report fewer complications and better quality of life overall.
When Surgery Becomes Necessary
Many people live with a prolapsed stoma for years using conservative management. Surgery is considered when the prolapse causes repeated problems: frequent inability to maintain a pouch seal, recurrent episodes where the bowel can’t be reduced back in, signs of compromised blood flow, or significant impact on daily life. Surgical options include revising the existing stoma, relocating it to a new site on the abdomen, or in some cases reversing the stoma entirely if the underlying condition allows it. The decision depends on why the stoma was created in the first place and whether the factors that caused the prolapse, like abdominal wall weakness, can be addressed during the repair.
