Rectal prolapse announces itself with a distinctive sensation: you feel something bulging out of or sliding through your anus, often during a bowel movement or while straining. In a full-thickness external prolapse, you can see and feel a dark-red, fleshy mass protruding from the anal opening, with visible circular folds of tissue. The condition can also involve pain, incomplete evacuation, mucous or bloody discharge, and fecal incontinence or constipation.1PubMed. Rectal prolapse: an overview of clinical features, diagnosis, and patient-specific management strategies Not every case is so obvious, though, and the trickier internal form can cause frustrating symptoms without anything visible on the outside.
What It Feels and Looks Like
The most unmistakable sign is a mass of tissue that pushes through the anus. Early on, this may happen only while you’re straining on the toilet and then slip back inside on its own. Over time, the prolapse can start appearing during everyday activities like walking, coughing, or even standing for long periods. Eventually it may stay out permanently and require you to push it back in with your hand.
Beyond the visible bulge, there are several other symptoms that point toward rectal prolapse:
- Mucous discharge: A persistent wetness or slimy residue around the anus, often staining underwear.
- Bleeding: Small amounts of bright red blood, particularly after bowel movements, from the exposed rectal lining rubbing against clothing or the toilet seat.
- Incomplete evacuation: The feeling that you haven’t fully emptied your bowels, sometimes causing repeated trips to the bathroom.
- Fecal incontinence: Leaking stool or losing control of gas, which happens because the prolapse stretches the anal sphincter muscles over time.
- Constipation: Difficulty passing stool, which can be both a cause and a consequence of the prolapse.
Pain is not always a major feature. Many people with rectal prolapse describe it as more uncomfortable and distressing than actually painful, though a prolapse that gets trapped outside and swells up can become quite sore.
External Prolapse Versus the Hidden Internal Kind
Rectal prolapse comes in two broad forms. External rectal prolapse is a full-thickness protrusion of the rectal wall through the anal canal. A key visual feature is that the prolapsed tissue has concentric, ring-like folds running around its surface.2PubMed Central. Current diagnostic tools and treatment modalities for rectal prolapse – Section: TYPES OF PROLAPSE If you were to look at it in a mirror (which, understandably, is not a comfortable exercise), you’d see these circular ridges rather than separate finger-like lumps.
Internal rectal prolapse, also called rectal intussusception, is sneakier. The rectal wall folds inward on itself but doesn’t actually poke through the anus. It typically starts about 6 to 8 centimeters above the anal opening and can range from a minor fold of just a few millimeters to a full circular invagination involving all layers of the rectal wall.2PubMed Central. Current diagnostic tools and treatment modalities for rectal prolapse – Section: TYPES OF PROLAPSE Because nothing is visible externally, the main clues are functional: you struggle to empty your bowels, feel a persistent sensation of something blocking the way, or deal with mucous discharge. Internal prolapse is sometimes only discovered through imaging studies done for other pelvic floor complaints.
How to Tell It Apart From Hemorrhoids
This is one of the most common points of confusion, and even some healthcare providers can initially mistake one for the other. The most reliable visual difference comes back to those tissue folds. A full-thickness rectal prolapse shows concentric, circular ridges because the entire rectal wall is turning inside out like a sock. Prolapsed hemorrhoids, on the other hand, have radial grooves, meaning the tissue appears to fan out from the center in separate segments or cushions with furrows running between them.2PubMed Central. Current diagnostic tools and treatment modalities for rectal prolapse – Section: TYPES OF PROLAPSE
The symptom profiles overlap somewhat. Both can cause bleeding, mucous discharge, and a sensation of something protruding. But hemorrhoids tend to cause itching and localized pain around the anus, while rectal prolapse is more associated with fecal incontinence and the feeling of incomplete evacuation. If you’re noticing leakage of stool or a growing inability to control gas alongside a visible lump, that pattern points more toward prolapse than hemorrhoids.
How Doctors Confirm the Diagnosis
A doctor who suspects rectal prolapse will usually start by asking you about your symptoms and then performing a physical exam. Here’s the catch: the prolapse doesn’t always cooperate during an office visit. If you’re lying on an exam table, relaxed, the rectum may be sitting perfectly inside with nothing to see. Clinical guidelines recommend that when a patient’s history suggests prolapse but nothing is visible, the patient should strain while sitting on a toilet, with or without the help of an enema or rectal balloon, so the perineum can be inspected in a sitting or squatting position.3Diseases of the Colon & Rectum. Clinical Practice Guidelines for the Treatment of Rectal Prolapse This might feel awkward, but it’s the most straightforward way to catch a prolapse that comes and goes.
For internal prolapse, or when the clinical picture is complicated by other pelvic floor issues, imaging becomes valuable. Dynamic MRI defecography is one tool that lets doctors watch your pelvic floor in real time while you simulate a bowel movement inside an MRI scanner. One study found that this type of imaging revealed additional diagnoses beyond what clinicians detected on physical exam in about a third of patients with complex pelvic floor disorders.4PubMed. Dynamic magnetic resonance imaging defecography: a diagnostic alternative in the assessment of pelvic floor disorders in proctology That extra diagnostic sensitivity matters because pelvic floor problems rarely travel alone.
Anorectal manometry, a test that measures the pressures generated by the anal sphincter muscles, can also be part of the workup. Research shows that people with rectal prolapse often have lower resting and squeezing pressures in the anal sphincter compared to healthy controls. Even patients who haven’t yet developed incontinence may already show reduced resting pressures, suggesting the internal sphincter starts weakening before obvious symptoms of leakage appear.5The American Journal of Surgery. Clinical and manometric evaluation of anal sphincter function in patients with rectal prolapse This kind of testing helps surgeons plan the right procedure and counsel patients about what to expect afterward.
Who Gets Rectal Prolapse and Why
The exact cause remains somewhat unclear, but the condition is linked to a set of anatomical features that allow the rectum to descend. These include a deep pouch between the rectum and uterus (or bladder), looseness in the ligaments and connective tissue that normally anchor the rectum to the pelvis, weakness in the pelvic floor muscles, loss of the normal curve of the sacrum, and a redundant sigmoid colon that provides too much slack.6PubMed Central. Update on the pathophysiology of rectal prolapse These defects don’t all have to be present at once, but when several combine, the rectum has less support and more room to telescope through the anal canal.
Women, especially older women, make up the majority of adult cases. Years of childbirth, hormonal changes, and cumulative strain on the pelvic floor all contribute. Men can develop rectal prolapse too, though it’s less common. In children, rectal prolapse has a different set of associations. Pediatric cases warrant screening for cystic fibrosis because about 3.5% of children with cystic fibrosis develop rectal prolapse, and roughly 3.6% of children presenting with rectal prolapse turn out to have previously undiagnosed cystic fibrosis.7PubMed. Rectal prolapse and cystic fibrosis
Chronic constipation and excessive straining are among the most commonly cited contributing factors. Neurological conditions that affect pelvic floor nerve function, previous pelvic surgery, and conditions that chronically raise abdominal pressure can also set the stage. Rectal prolapse often coexists with other forms of pelvic organ prolapse, and the two are increasingly being diagnosed together.8PubMed Central. Management of Pelvic Organ Prolapse (POP) and Rectal Prolapse If you have symptoms suggesting bladder prolapse or uterine descent alongside rectal symptoms, it’s worth mentioning both to your doctor so the full picture can be evaluated at once.
What to Do If It Comes Out and Won’t Go Back
Most of the time, an external prolapse slides back in on its own or can be gently pushed back with a clean hand. But occasionally the prolapsed tissue gets trapped outside the anus and swells up, a situation called incarceration. This is a genuine urgency. If the blood supply to the trapped tissue gets cut off, strangulation can occur, which is a surgical emergency.1PubMed. Rectal prolapse: an overview of clinical features, diagnosis, and patient-specific management strategies
An old but still-used first-aid trick involves applying ordinary granulated sugar to the swollen, incarcerated tissue. The sugar draws fluid out of the swollen tissue through osmosis, reducing the edema enough that the bowel can sometimes be gently eased back inside.9PubMed. Sugar in the reduction of incarcerated prolapsed bowel. Report of two cases. This technique has been described in case reports for both prolapsed rectums and prolapsed stomas.10BMJ Case Reports. Granulated sugar to reduce an incarcerated prolapsed defunctioning ileostomy It is a temporizing measure to try while getting to medical care, not a substitute for evaluation. If you can’t reduce a trapped prolapse, or if the tissue looks dark purple or black, head to an emergency department immediately.
Treatment Options Once You Know
Treatment depends heavily on the severity of the prolapse, your overall health, and your symptoms. For mild or internal prolapse, conservative measures are the starting point. Addressing constipation with dietary fiber and adequate fluids, learning to avoid excessive straining, and doing pelvic floor exercises can all help. One case report described an older adult with rectal prolapse who, over just seven visits of integrative physical therapy combining pelvic floor training, acupressure, and mindfulness techniques, reported a 90% reduction in prolapse severity and complete resolution of rectal pain that had been rated five out of ten at baseline.11Journal of Women’s & Pelvic Health Physical Therapy. Conservative Management of Rectal Prolapse in an Older Adult Using Acupressure and Integrative Physical Therapy: A Case Report A single case report is not enough to generalize from, but it illustrates that non-surgical approaches can be meaningful for some people.
For full-thickness external prolapse, surgery is usually the definitive treatment. Broadly, procedures are divided into abdominal approaches, which go in through the belly to anchor the rectum back in place, and perineal approaches, which work through the anus itself. Perineal procedures are generally reserved for patients who are elderly, frail, or have multiple health conditions that make general anesthesia risky.12PubMed Central. Perineal approaches to rectal prolapse Abdominal procedures, including laparoscopic techniques, tend to have lower recurrence rates. One prospective study of laparoscopic repair found that incontinence improved significantly regardless of the specific technique used, constipation resolved in about two-thirds of patients, and only about 7% developed recurrent prolapse over a median follow-up of two years.13PubMed. Laparoscopic repair of rectal prolapse: a prospective study evaluating surgical outcome and changes in symptoms and bowel function
When prolapse recurs after surgery, the question of which approach to use the second time gets more complex. In one series of patients with recurrent prolapse, about 60% underwent perineal approaches and 40% had abdominal procedures. The heavy lean toward perineal surgery reflected the reality of the patient population: the average age was just over 70, and nearly all had significant coexisting health issues.14PubMed Central. Comparison of abdominal and perineal approach for recurrent rectal prolapse The choice between approaches comes down to a conversation between you and your surgeon about your risk tolerance, your fitness for general anesthesia, and how much the recurrence is affecting your quality of life.
The Toll on Daily Life and Mental Health
Rectal prolapse doesn’t just cause physical discomfort. Many people living with it experience embarrassment, social withdrawal, and difficulty maintaining intimate relationships. The constant worry about leakage, odor, or the prolapse becoming visible affects daily decisions about what to wear, where to go, and whether to exercise. People often delay seeking help for years because of shame, which unfortunately allows the condition to progress.
Research on quality of life in women with rectal prolapse has found that physical symptoms and depressive symptoms interact with each other in ways that compound the damage to both physical and mental well-being. Depressive symptoms had a significant direct effect on physical quality of life in women with colorectal and urinary distress symptoms, and the interplay between pelvic organ prolapse symptoms and depression affected mental quality of life as well.15PubMed Central. Interaction and main effects of physical and depressive symptoms on quality of life in Korean women seeking care for rectal prolapse: a cross-sectional observational study In other words, the physical symptoms feed the depression and the depression amplifies the perception of physical symptoms, creating a cycle that is hard to break without addressing both sides.
Does How You Sit on the Toilet Matter?
There’s a persistent idea that the modern seated toilet contributes to pelvic floor disorders, including rectal prolapse. The argument goes that sitting at a 90-degree angle forces you to strain harder because the puborectalis muscle, which wraps around the rectum like a sling, doesn’t fully relax in that position. Squatting opens the anorectal angle and theoretically allows stool to pass with less pushing.
Some research supports the plausibility of this idea. One analysis of toilet design and pelvic health suggested that the pressure generated by the diaphragm during defecation, combined with the apparent relaxation of abdominal muscles in the seated position, pushes pelvic organs downward and can contribute to conditions like uterine prolapse, cystocele, and rectocele, particularly in women.16PubMed Central. Health promotion and prevention of bowel disorders through toilet designs: A myth or reality? The evidence here is more theoretical than proven by large trials, but it aligns with what we know about straining as a risk factor. If you already have rectal prolapse or are at risk, placing a small footstool in front of your toilet to raise your knees above your hips mimics a partial squat and may reduce the effort needed for bowel movements. It’s a low-cost, low-risk change that many colorectal specialists informally recommend.
When to See a Doctor
If you’ve noticed a mass coming out of your anus, don’t wait. Even if it goes back in on its own, the fact that it appeared at all means something structural is happening that is unlikely to resolve without attention. The same goes for a persistent feeling of something blocking your bowel movements, new-onset fecal incontinence, or unexplained mucous discharge.
Some people convince themselves they just have hemorrhoids and buy over-the-counter creams for months or years. While hemorrhoid treatments might soothe surface irritation, they do nothing for a prolapsing rectum. The distinction matters because untreated rectal prolapse can progressively stretch and weaken the anal sphincter, making incontinence worse over time and potentially making any future surgery less effective. Sphincter damage can begin even before you notice obvious leakage, as reduced resting pressures in the anal canal suggest early internal sphincter dysfunction.5The American Journal of Surgery. Clinical and manometric evaluation of anal sphincter function in patients with rectal prolapse Getting evaluated sooner rather than later gives you more options and better odds of preserving continence.
