How to Tell the Difference Between Hemorrhoids and Rectal Prolapse

The single most reliable visual clue is the pattern of folds in the protruding tissue. Hemorrhoids bulge outward in distinct columns separated by grooves that radiate from the center like spokes on a wheel, while a complete rectal prolapse pushes out as a ring of tissue with circular, concentric folds running around its circumference. That difference sounds straightforward in a textbook, but in practice the two conditions can look surprisingly similar, especially when tissue is swollen, and misdiagnosis between them is common enough that surgeons have written entire papers warning colleagues about the problem.

The Fold Pattern That Clinicians Look For

When tissue protrudes from the anus, the first thing a doctor examines is how that tissue is arranged. Prolapsed internal hemorrhoids are swollen vascular cushions, and they tend to protrude as separate lumps with grooves between them. Those grooves run outward from the anal opening, creating a radial or spoke-like pattern. By contrast, a complete rectal prolapse involves the entire wall of the rectum sliding out through the anal canal. Because the full circumference of the rectum is involved, the mucosal folds wrap around the protruding mass in concentric rings, much like the rings on a target or the ridges on a stack of tires.¹

This distinction holds up on surgical imaging as well. Figures in surgical literature consistently show that even when hemorrhoid tissue is severely swollen or darkened from reduced blood flow, the radial grooves between the hemorrhoid cushions remain visible. A rectal prolapse, on the other hand, presents a smooth, continuous ring of mucosa without those radial divisions.²

If you are trying to check at home with a mirror, look for those grooves. Hemorrhoids typically appear as two or three distinct bulges with visible furrows between them. A prolapse looks more like a doughnut or tube of pink tissue with rings going around it. That said, home assessment has real limits, and a doctor can confirm the diagnosis with a brief exam.

How the Two Conditions Feel Different

The symptom profiles overlap more than most people expect, which is part of why confusion between the two is so common. Both can cause a sensation of something bulging from the anus, both can cause bleeding, and both can produce mucus discharge. But there are patterns worth noting.

Hemorrhoids tend to cause itching, bright red blood on the toilet paper or in the bowl, and a feeling of incomplete evacuation. The tissue usually pops back inside on its own after a bowel movement, at least in earlier stages. Pain is not always a major feature of internal hemorrhoids unless they become thrombosed (clotted) or strangulated.

Rectal prolapse, on the other hand, is more strongly associated with a dragging or heavy sensation in the pelvis, difficulty controlling bowel movements, and significant mucus leakage. The protruding tissue may initially reduce on its own but over time requires manual pushing to get it back inside. A key difference many people notice is that rectal prolapse tends to appear during activities other than just bowel movements. Coughing, sneezing, standing for a long time, or any exertion that increases abdominal pressure can push the rectum out, whereas hemorrhoids are more closely tied to straining during defecation.

Fecal Incontinence as a Distinguishing Signal

One symptom that strongly tilts the diagnosis toward rectal prolapse rather than hemorrhoids is fecal incontinence, meaning involuntary leakage of stool. While hemorrhoids can cause minor soiling due to mucus, actual loss of bowel control is far more characteristic of rectal prolapse. The reason is mechanical: when the rectum repeatedly slides out through the anal canal, it stretches and damages the anal sphincter muscles over time. Research comparing continent and incontinent patients with rectal prolapse found that internal anal sphincter defects were dramatically more common in the incontinent group, occurring in about 60% of those patients compared with roughly 6% of those who maintained continence.³

So if you are experiencing regular involuntary leakage along with tissue protruding from the anus, that combination points more strongly toward prolapse than hemorrhoids. Hemorrhoids can certainly be uncomfortable and messy, but they do not typically compromise the sphincter mechanism in the same way.

The Straining Test

When a patient visits a clinician with a protruding mass from the anus, one of the simplest and most informative diagnostic steps is simply asking the patient to strain as though having a bowel movement, often while seated on a commode or in a squatting position. Rectal prolapse can be diagnosed this way because the full-thickness protrusion tends to emerge during straining and is clearly visible to the examiner.¹ The key detail the examiner watches for is whether the tissue coming out forms that telltale concentric-ringed tube or whether it appears as separate cushions with radial grooves.

A digital rectal examination, where the doctor inserts a gloved finger into the rectum, adds information about sphincter tone and the presence of a mass. Low sphincter tone at rest is a red flag for prolapse. The clinician may also use an anoscope, a short lighted tube, to look at the anal canal from the inside and identify the source of any bleeding or swelling.

In many cases, the physical exam alone settles the diagnosis. The trouble arises when the prolapse is intermittent and does not appear during the office visit, or when the hemorrhoids are so severely prolapsed that they mimic the appearance of a rectal prolapse. These are the cases where more advanced testing comes in.

When Imaging Is Needed

For straightforward cases, no imaging is required. But when the clinical picture is ambiguous, or when a surgeon needs to plan a repair and wants a full map of pelvic floor anatomy, dynamic MRI defecography is one of the most useful tools. This involves an MRI scan taken while the patient bears down or evacuates, so the radiologist can watch the pelvic organs in real time. It can distinguish between mucosal prolapse (where only the inner lining of the rectum slides), full-thickness rectal prolapse (where the entire rectal wall comes through), and internal intussusception (where the rectum folds in on itself but does not exit the anus).⁴

This type of imaging is especially valuable for people who have had prior pelvic or perineal surgery, where scar tissue can make physical examination less reliable. In one study, MRI defecography confirmed the clinical diagnosis about three-quarters of the time but also picked up additional pelvic floor problems that the physical exam had missed in about a third of patients.⁵ That matters because rectal prolapse often coexists with other pelvic floor issues like cystocele (bladder prolapse) or enterocele (small bowel descent), and missing those at the time of diagnosis can lead to incomplete treatment.

Why Getting the Diagnosis Right Matters So Much

The reason surgeons write cautionary papers about this distinction is that the treatments for hemorrhoids and rectal prolapse are fundamentally different, and applying the wrong one can make things worse. Hemorrhoid management ranges from dietary changes and topical treatments for mild cases to procedures like rubber band ligation or hemorrhoidectomy for more severe ones. In a large retrospective comparison, hemorrhoidectomy resolved symptoms in about 96% of cases as a standalone procedure, while rubber band ligation required a second session in about a third of patients.⁶

Rectal prolapse, by contrast, almost always requires surgical repair. The two main categories of operation are abdominal approaches (where the surgeon works from inside the abdomen to anchor the rectum back in place) and perineal approaches (where the repair is done from below, through the anal opening). Neither of these would be appropriate for hemorrhoids, and performing a hemorrhoid procedure on tissue that is actually prolapsed rectum can fail to fix the problem while adding complications.

The confusion runs in both directions. A patient with severe prolapsing hemorrhoids may undergo unnecessary prolapse surgery, and a patient with early rectal prolapse may receive hemorrhoid treatments that provide only temporary relief because the underlying cause was never addressed.

When the Two Conditions Coexist

Here is a wrinkle that makes things even more complicated: hemorrhoids and rectal prolapse can occur in the same person at the same time. Internal rectal prolapse, where the rectum telescopes into itself without fully exiting the anus, can contribute to hemorrhoid formation by increasing venous pressure in the anal cushions. One study examining patients with outlet obstruction constipation specifically enrolled those with both internal rectal prolapse and circumferential hemorrhoids, indicating this is a recognized combined presentation.⁷

When both are present, the surgical strategy needs to address both issues. Treating only the hemorrhoids while ignoring the underlying prolapse sets the patient up for recurrence because the mechanical forces that created the hemorrhoids in the first place are still at work. Similarly, fixing the prolapse and leaving severe hemorrhoids untreated means the patient still has symptoms afterward. This is one reason thorough preoperative evaluation, sometimes including both physical exam and imaging, is so valuable.

The co-occurrence also partially explains why recurrence rates after hemorrhoid surgery are not zero. If there is an undiagnosed component of internal prolapse contributing to the hemorrhoids, the hemorrhoids are more likely to come back.

Hemorrhoids That Develop After Prolapse Repair

An unexpected finding in the surgical literature is that a meaningful number of patients develop significant hemorrhoids after undergoing surgery for rectal prolapse. One study tracking patients after laparoscopic ventral mesh rectopexy, a common abdominal approach for prolapse repair, found that roughly one in four patients developed hemorrhoids severe enough to need a second operation within five years.⁸

The suspected reason is that anchoring the rectum back in place can change the dynamics of blood flow and pressure in the anal cushions, effectively trading one problem for another. This does not mean the prolapse surgery was wrong to perform, but it does mean that patients undergoing prolapse repair should be counseled about this possibility so they are not caught off guard when hemorrhoid symptoms appear months or years later.

Emergency Situations

Both conditions can become emergencies, though the mechanisms differ. Hemorrhoids can become acutely thrombosed, meaning a blood clot forms inside the swollen vein, causing sudden severe pain and a hard, tender lump. Internal hemorrhoids can also become strangulated if they prolapse and the sphincter clamps down on them, cutting off blood supply. This causes intense pain, swelling, and sometimes tissue death if not treated promptly.

Rectal prolapse becomes an emergency when the protruding rectum cannot be pushed back inside (irreducible prolapse) or when the tissue loses its blood supply (strangulated prolapse). Strangulated rectal prolapse is a surgical emergency. A thorough physical examination including digital rectal exam and anoscopy is considered essential for distinguishing between these acute presentations and planning the right urgent treatment.⁹

In an emergency room setting, the distinction between a strangulated hemorrhoid and an irreducible rectal prolapse carries high stakes. The fold pattern described earlier still applies even when tissue is swollen and discolored: radial grooves between distinct cushions point to hemorrhoids, while a continuous ring of tissue with circumferential folds indicates prolapse. If you find yourself in an emergency with tissue protruding from the anus that you cannot push back in, has turned dark purple or black, or is causing excruciating pain, get to an emergency room. Do not try to force anything back in.

Who Gets Each Condition

The risk profiles for hemorrhoids and rectal prolapse are different enough to be useful as a soft diagnostic clue. Hemorrhoids are extremely common across all age groups and affect roughly half of all adults at some point. Risk factors include chronic constipation, prolonged sitting, pregnancy, obesity, and heavy lifting. They are an equal-opportunity condition without a strong sex preference.

Rectal prolapse has a more distinctive demographic pattern. It is most common in older women, particularly those who have had multiple vaginal deliveries, due to weakening of the pelvic floor muscles over decades. It also occurs in young children, where it is usually self-limiting and linked to constipation or conditions like cystic fibrosis. In men it is less common and more frequently associated with neurological conditions or chronic straining. If you are an older woman with tissue protruding from the anus, rectal prolapse deserves serious consideration alongside hemorrhoids. If you are a 30-year-old man with bright red blood and some tissue bulging during bowel movements, hemorrhoids are far more likely, though not guaranteed.

Chronic straining is a shared risk factor for both conditions, which is one reason they can coexist and one reason lifestyle measures like adequate fiber intake, staying hydrated, and not sitting on the toilet for extended periods are recommended regardless of which diagnosis you end up with. Those measures will not cure a full-thickness rectal prolapse, but they can slow its progression and reduce the severity of accompanying hemorrhoid symptoms.

Internal Prolapse and the Gray Zone

Full-thickness rectal prolapse that protrudes outside the body is relatively easy to distinguish from hemorrhoids with a good physical exam. The much harder diagnostic territory is internal rectal prolapse, also called rectal intussusception, where the rectal wall folds inward and telescopes down but does not actually come out through the anus. This condition produces symptoms that overlap heavily with hemorrhoids: bleeding, mucus, a feeling of incomplete evacuation, and difficulty passing stool.

Because the prolapse stays inside, there is no external tissue to examine for fold patterns. Diagnosis typically requires either defecography (a special X-ray taken while the patient evacuates a contrast-filled paste) or the dynamic MRI defecography described earlier. Internal prolapse is thought to be an earlier stage that can progress to full external prolapse in some patients, though not all cases progress. If you have persistent hemorrhoid-like symptoms that do not respond to standard hemorrhoid treatments, internal prolapse is one of the conditions your doctor should consider investigating.

The concept of a spectrum from internal intussusception to partial external prolapse to full-thickness external prolapse is well accepted in colorectal surgery. Where a given patient falls on that spectrum affects both the treatment approach and the likely outcome. Manometry, which measures the pressures generated by the anal sphincters, and defecography are sometimes used together to get a complete picture before deciding on surgery.¹⁰

What a Home Self-Check Can and Cannot Tell You

If tissue is protruding from your anus and you want to get a preliminary sense of whether you are dealing with hemorrhoids or prolapse before seeing a doctor, a mirror and good lighting can help. Look for these features:

• Separate lumps with grooves: Distinct bulges with visible furrows running between them, like segments of a flower, suggest hemorrhoids.
• A continuous ring or tube: A smooth, symmetrical cylinder of tissue with ridges wrapping around it in circles suggests rectal prolapse.
• Color: Hemorrhoids are often a mix of purple and skin-colored. Prolapsed rectal tissue tends to be uniformly pink or red, similar to the inside of your cheek.
• Size: Rectal prolapse tends to produce a larger mass than hemorrhoids. A protrusion the size of a golf ball or larger that appears as a uniform tube is more consistent with prolapse.
• When it appears: Tissue that comes out mainly during bowel movements and goes back in on its own is more consistent with hemorrhoids. Tissue that appears with coughing, walking, or standing and needs to be pushed back in manually is more suggestive of prolapse.

None of these features are diagnostic on their own, and self-assessment cannot replace a clinical evaluation. Both conditions deserve medical attention, but the urgency differs. Hemorrhoids that are bothersome but manageable can wait for a routine appointment. Any tissue that you cannot push back inside, that is turning dark, or that is accompanied by loss of bowel control warrants a prompt visit to a doctor or emergency room.
