The most obvious sign of rectal prolapse is a reddish lump of tissue that comes out of the anus, usually while straining during a bowel movement. In early stages, this tissue may slide back inside on its own. In more advanced cases, it stays out or reappears with everyday activities like coughing, sneezing, or lifting. If you’re noticing something bulging from your anus along with changes in bowel habits, there’s a good chance that’s what you’re dealing with.
What Rectal Prolapse Looks and Feels Like
The hallmark symptom is visible tissue protruding from the anus. It often appears during or after a bowel movement and looks like a moist, dark red or pinkish mass. You may also notice:
- Mucus or blood leaking from the rectum
- A feeling that your rectum isn’t empty after a bowel movement
- Difficulty controlling bowel movements (fecal incontinence)
- Constipation or loose stools that seem to worsen over time
- A persistent sense of pressure or fullness in the rectal area
Some people first notice the prolapse only when wiping, feeling a soft bulge that wasn’t there before. Over time, it can appear when you sneeze, stand for long periods, or do anything that increases pressure in your abdomen.
Three Types, Three Levels of Severity
Not all rectal prolapse is the same. There are three distinct forms, and they range from invisible to unmistakable.
Internal prolapse (intussusception) is the earliest and hardest to detect on your own. The rectal wall folds inward but doesn’t come out of the anus. You won’t see anything, but you may feel like you can’t fully empty your bowels, or you may strain more than usual. Many people with internal prolapse never progress beyond this stage.
Mucosal prolapse involves only the inner lining of the rectum pushing out through the anus. The bulge tends to be smaller and may look similar to a hemorrhoid.
Full-thickness prolapse means the entire wall of the rectum pushes through the anus. This is the most recognizable form. One theory in the surgical literature holds that full-thickness prolapse often begins as internal intussusception that starts about 6 to 8 centimeters above the anal opening and gradually worsens with repeated straining over months or years.
Rectal Prolapse vs. Hemorrhoids
This is the confusion most people have, and the distinction matters because treatment is completely different. Both can cause a bulge near the anus, bleeding, and itching. But there are reliable ways to tell them apart.
The key visual difference is the pattern of the tissue folds. A full-thickness rectal prolapse has concentric, circular folds, like rings around the protruding tissue. Hemorrhoids, by contrast, have radial folds that fan outward like the segments of an orange. If you’re looking at tissue that forms uniform rings, that points strongly toward prolapse.
Symptom-wise, rectal prolapse is more likely to cause fecal incontinence, mucus discharge, and a bulge that appears with coughing or lifting, not just during bowel movements. Hemorrhoids more commonly cause localized pain, a firm lump, and bright red blood on toilet paper. If you’re experiencing leakage you can’t control alongside a visible bulge, that combination is much more characteristic of prolapse than hemorrhoids.
Who Is Most at Risk
About 80 to 90 percent of adults with rectal prolapse are women, and the condition is most common in people over 50. A Finnish population study found that roughly 2.5 out of every 100,000 people are diagnosed with complete rectal prolapse each year, making it relatively uncommon but not rare.
Several factors increase your risk. Chronic constipation and habitual straining during bowel movements are the most frequently cited. Chronic diarrhea, prior pelvic surgery, and conditions that weaken the pelvic floor muscles or the nerves controlling them also contribute. In structural terms, people who develop prolapse often have a rectum that isn’t firmly anchored in place, combined with weak anal sphincter muscles and a weakened pelvic floor.
In children, rectal prolapse is rare and typically occurs before age 4. It’s associated with cystic fibrosis and differences in rectal anatomy, such as the rectum sitting in a straighter, more vertical position than usual.
How Doctors Confirm the Diagnosis
If you suspect rectal prolapse, a physical exam is the starting point. Your doctor will perform a digital rectal exam, inserting a gloved, lubricated finger into the rectum to assess sphincter strength and feel for abnormalities. You’ll likely be asked to bear down as if having a bowel movement so the doctor can watch for tissue sliding out.
Here’s the catch: prolapse doesn’t always show up on command. If your doctor suspects it but can’t see it during the exam, you may be asked to strain while sitting on a toilet, sometimes after an enema, to reproduce what you’ve been experiencing at home. Some doctors will even ask you to photograph the prolapse at home when it happens, since it can be intermittent.
When the physical exam isn’t conclusive, imaging studies help. Defecography is one of the most useful tests. You’re given a contrast dye, and then X-ray or MRI imaging captures what happens in your lower digestive tract while you bear down. This reveals both the structural changes and how well your rectal muscles are functioning. It’s particularly valuable for detecting internal prolapse that doesn’t come through the anus.
Other tests your doctor may order include anal manometry, which measures the tightness of your anal sphincter using a small flexible tube with an inflatable balloon, and colonoscopy, which rules out other conditions like polyps, hemorrhoids, or colon cancer that could be contributing to your symptoms.
Signs That Need Urgent Attention
Most rectal prolapse develops gradually and isn’t a medical emergency. But there is one serious complication to watch for: strangulation. This happens when prolapsed tissue gets trapped outside the anus and its blood supply is cut off. The tissue may turn dark purple or black, swell significantly, and become very painful. Left untreated, strangulation can lead to tissue death. If you have a prolapse that you cannot push back into place and it’s becoming increasingly painful, swollen, or discolored, that requires immediate medical care.
Why Self-Assessment Has Limits
You can spot the obvious signs of a full-thickness prolapse on your own, especially if tissue is visibly coming out. But internal prolapse produces no visible bulge, and mucosal prolapse can look nearly identical to prolapsed hemorrhoids without the trained eye to distinguish the fold patterns. Even in clinical settings, the digital rectal exam has limitations. Research has shown that while it’s reasonably sensitive for detecting major sphincter problems, it has poor specificity, meaning a “normal” exam doesn’t necessarily rule out underlying muscle weakness or damage. The physical exam is a starting point, not the final word, which is why imaging like defecography plays such an important role when symptoms are present but the diagnosis is uncertain.
