Hemorrhoids affect a large portion of adults, with prevalence increasing notably with age1 . Prolapsed hemorrhoids occur when internal hemorrhoids bulge outside the anus, causing symptoms such as pain, bleeding, and itching2 . While many cases improve with conservative care, some require medical or surgical intervention to relieve discomfort and prevent complications3 . Understanding the causes, symptoms, diagnosis, and treatment options can help manage this common condition effectively4 .
Recognizing Symptoms
Prolapsed hemorrhoids are swollen veins in the lower rectum and anus that protrude outside the anus due to increased pressure and weakened tissue support4 . The main symptom is a soft lump or bulge around the anus, which may be felt during wiping or sitting2 . Other common symptoms include:
- Bright red rectal bleeding, often visible on the stool surface or toilet paper5
- Pain and discomfort, especially when sitting or during bowel movements6
- Itching and irritation around the anus (pruritus) 6
- Mucus discharge from the anus due to irritation5
- A sensation of incomplete evacuation or feeling like stool is stuck after wiping2
- Occasional minor fecal leakage in some cases7
Symptoms may be intermittent and tend to worsen progressively over time8 . Prolapsed hemorrhoids can cause swelling and sensitivity in the anal area, leading to discomfort9 . Pain is usually more pronounced if the hemorrhoid becomes strangulated or thrombosed (clotted) 3.
💡 Did You Know?
A prolapsed hemorrhoid is when an internal hemorrhoid bulges outside of your anus. It can cause uncomfortable symptoms like itching and pain2 .
Causes of Prolapsed Hemorrhoids
Prolapsed hemorrhoids develop when the veins in the rectal area become swollen and engorged due to increased pressure in the anorectal venous plexus6 . This venous dilation, combined with weakening of the supporting tissues, causes the hemorrhoidal cushions to descend beyond the anal canal, resulting in prolapse5 . The pathogenesis mainly involves prolapse of the anal cushions, which normally help maintain continence10 .
Risk Factors
Several factors increase the risk of developing prolapsed hemorrhoids by raising intra-abdominal or rectal venous pressure or weakening tissue support6 :
- Excessive straining during bowel movements, often due to constipation or low fiber intake6 5
- Chronic constipation leading to hard stools and increased straining5
- Low dietary fiber intake, which contributes to constipation and hemorrhoidal risk5
- Prolonged sitting on the toilet, increasing pressure on the anal veins4
- Pregnancy, which causes increased pelvic pressure and venous congestion11 3
- Obesity, contributing to increased intra-abdominal pressure3
- Frequent heavy lifting or strenuous physical activity6
- Aging, which weakens connective tissues supporting the hemorrhoidal cushions8
These factors promote venous dilation and tissue laxity, facilitating hemorrhoidal prolapse8 .
Increased straining during defecation may trigger symptoms like bleeding and prolapse in patients with hemorrhoidal disease. Pregnancy can also predispose to congestion of the anal cushions, often resolving after birth11 .
Diagnosing Prolapsed Hemorrhoids
Diagnosis begins with a detailed medical history focusing on symptom onset, frequency, and severity5 . Assessment of dietary habits, bowel patterns, and family history helps identify risk factors and rule out other conditions8 . Physical examination includes inspection of the anal area for visible prolapse and external signs such as swelling or skin irritation5 .
Straining during examination can reveal prolapsed hemorrhoids not visible at rest5 . A digital rectal exam is a key initial diagnostic tool to assess internal hemorrhoids and exclude other anorectal conditions6 . Additional diagnostic tests may include anoscopy or imaging studies if needed5 .
Differential diagnosis is important to distinguish prolapsed hemorrhoids from other causes of rectal protrusion, such as rectal prolapse (full-thickness rectal wall protrusion) or rectal polyps12 13.
Stages of Prolapsed Hemorrhoids
Prolapsed hemorrhoids are classified based on the degree of prolapse, which guides treatment decisions14 :
| Grade | Description | Clinical Features | Management Implications |
|---|---|---|---|
| I | No prolapse; hemorrhoids bleed but remain inside the anal canal | May cause painless bleeding5 | Usually managed conservatively15 |
| II | Prolapse during defecation but reduce spontaneously | Intermittent prolapse, mild symptoms5 4 | Office procedures often effective16 |
| III | Prolapse requires manual reduction | More frequent prolapse, discomfort4 | May require procedural treatment6 |
| IV | Prolapsed permanently and cannot be reduced | Persistent protrusion, significant symptoms4 | Often requires surgical intervention17 |

Prolapse may be transient during bowel movements or permanent in advanced stages5 4.
Treatment Options for Prolapsed Hemorrhoids
Treatment depends on symptom severity and hemorrhoid grade5 . Many cases respond well to conservative care, while others may need office-based procedures or surgery.
At-Home Treatments
First-line management focuses on lifestyle and dietary modifications to reduce symptoms and prevent progression5 6:
- Increase dietary fiber intake to soften stools and reduce straining5
- Maintain adequate hydration to support regular bowel movements6
- Avoid prolonged sitting and straining during defecation5
- Use stool softeners if constipation is present8
- Take sitz baths (warm water baths) to relieve pain and inflammation6
- Apply over-the-counter topical treatments containing hydrocortisone, witch hazel, or lidocaine for symptom relief2 18
- Use oral analgesics to manage discomfort if needed8
Many prolapsed hemorrhoids improve or resolve with these measures alone8 3.
In-Office Procedures
For symptomatic grades II and III hemorrhoids or those refractory to conservative care, minimally invasive procedures are effective16 5:
- Rubber band ligation: placing a band around the hemorrhoid base to cut off blood supply, causing it to shrink16 18
- Sclerotherapy: injection of a sclerosing agent to shrink hemorrhoidal tissue16 18
- Infrared coagulation or laser therapy: using heat to reduce hemorrhoid size5 18
These procedures are generally safe, performed in outpatient settings, and have quick recovery times16 18.
Surgery
Surgical intervention is reserved for severe, persistent, or grade IV prolapsed hemorrhoids17 19:
- Hemorrhoidectomy: surgical removal of hemorrhoidal tissue, effective for large or thrombosed hemorrhoids17 18
- Stapled hemorrhoidopexy (Procedure for Prolapse and Hemorrhoids, PPH): circular stapling to reposition prolapsed tissue with less postoperative pain and faster recovery20 21
- Emerging minimally invasive techniques like high-intensity focused ultrasound rectoanal lifting (HIFU-RAL) show promise in reducing complications22 23
Surgery carries risks of postoperative pain and complications but offers definitive treatment for advanced cases24 17.
“Procedure for Prolapse and Hemorrhoids (PPH), also known as circular stapled hemorrhoidectomy, is a common method of treating hemorrhoids due to its low risk of complications and minimal postoperative pain.”

Preventing Prolapsed Hemorrhoids
Prevention focuses on reducing rectal venous pressure and promoting bowel health through lifestyle changes8 6:
- Eat a high-fiber diet to prevent constipation and reduce straining5
- Drink plenty of fluids to maintain stool softness6
- Avoid prolonged sitting on the toilet and straining during bowel movements8
- Use stool softeners if prone to constipation6
- Limit heavy lifting and strenuous activities that increase intra-abdominal pressure5
- Engage in regular exercise to promote bowel regularity8
These measures help maintain tissue strength and reduce the risk of hemorrhoidal prolapse6 .
Potential Complications
Serious complications from hemorrhoids are uncommon but can occur if prolapsed hemorrhoids remain untreated5 6. Potential issues include:
- Severe pain and discomfort from chronic prolapse6
- Strangulated hemorrhoids, where blood supply is cut off causing ischemia, ulceration, and tissue necrosis5 6
- Chronic bleeding leading to iron deficiency anemia, presenting with fatigue and weakness8 6
- Thrombosed hemorrhoids causing intense pain due to blood clots within swollen veins3
Urgent medical treatment is required for strangulated or thrombosed hemorrhoids to prevent tissue damage8 .
Untreated prolapsed hemorrhoids may cause severe pain and discomfort. Chronic bleeding can lead to iron deficiency anemia, which may cause fatigue and cognitive changes6 .
