Understanding Rectal Prolapse: Causes and Treatments
Rectal prolapse is a medical condition that can significantly impact a person's quality of life. Understanding its causes, symptoms, and treatment options is crucial for effective management.
In this article, we delve deep into rectal prolapse, exploring its grading system, distinguishing it from haemorrhoids, and discussing both conservative and surgical treatment options.

Get A Second OpinionWhat is Rectal Prolapse?
Rectal prolapse occurs when the rectum, the final section of the large intestine, loses its normal attachments and slips through the anus, causing it to protrude externally. This condition can be both distressing and painful, leading to various complications if not treated appropriately.
Causes of Rectal Prolapse
Anatomical and Physiological Factors
The primary causes of rectal prolapse are often related to anatomical and physiological changes within the body. These can include:
- Weakness of the Pelvic Floor Muscles: The muscles and ligaments supporting the rectum may weaken due to ageing, childbirth, or chronic straining during bowel movements.
- Neurological Conditions: Diseases such as multiple sclerosis or spinal cord injuries can impact the nerves that control the rectum, leading to prolapse.
- Chronic Constipation or Diarrhea: Persistent straining during bowel movements can weaken the pelvic floor muscles over time.
Secondary Causes
Other factors that may contribute to rectal prolapse include:
- Genetic Predisposition: Some individuals may be genetically prone to developing rectal prolapse.
- Previous Surgeries: Surgical procedures involving the pelvic area can sometimes weaken the support structures of the rectum.
Symptoms of Rectal Prolapse
Recognizing the symptoms of rectal prolapse is essential for timely diagnosis and treatment. Key symptoms include:
- Visible Protrusion: The most evident symptom is a visible bulge or protrusion from the anus, especially during bowel movements.
- Anal Discomfort: Patients may experience pain, itching, or a sensation of incomplete evacuation after bowel movements.
- Incontinence: In severe cases, there may be faecal incontinence or leakage of mucus.
Rectal Prolapse vs Hemorrhoids
It's crucial to differentiate between rectal prolapse and haemorrhoids, as the treatment approaches for these conditions differ significantly.
Rectal Prolapse
Rectal prolapse involves the entire wall of the rectum protruding through the anus. This condition often requires surgical intervention to correct.
Hemorrhoids
Hemorrhoids, on the other hand, are swollen blood vessels in the anal canal. They can cause symptoms such as bleeding, itching, and discomfort but typically do not involve the rectal wall's protrusion. Hemorrhoids are usually treated with lifestyle changes, medications, or minimally invasive procedures.
Grading of Rectal Prolapse
Rectal prolapse is graded based on the extent of the prolapse. This grading system helps determine the appropriate treatment approach.
Grade I: Partial Prolapse
In Grade I prolapse, only the mucosa (the innermost lining of the rectum) protrudes through the anus. This is often referred to as a mucosal prolapse.
Grade II: Complete Prolapse
Grade II prolapse involves the full thickness of the rectal wall protruding through the anus. This is the most common and most severe form of rectal prolapse.
Grade III: Full Thickness Prolapse with Incarceration
In Grade III prolapse, the entire rectal wall protrudes, and the prolapsed segment becomes trapped outside the anus, leading to incarceration. This condition often requires emergency surgical intervention.
Treatment Options for Rectal Prolapse
Treatment for rectal prolapse depends on the severity of the condition and the patient's overall health. Both conservative and surgical options are available.
Conservative Treatments
For mild cases of rectal prolapse, conservative treatments may be effective. These include:
- Dietary Changes: Increasing fibre intake and staying hydrated can help prevent constipation and reduce straining during bowel movements.
- Pelvic Floor Exercises: Strengthening the pelvic floor muscles through exercises such as Kegels can provide better support to the rectum.
- Stool Softeners: Medications to soften stools can reduce straining and alleviate symptoms.

In more severe cases or when conservative treatments fail, surgical intervention may be necessary. Several surgical options are available, each tailored to the patient's specific condition.
Rectopexy
Rectopexy is a surgical procedure that involves repositioning and securing the rectum to its original position. This can be done through open surgery or minimally invasive techniques such as laparoscopy. Rectopexy is often recommended for Grade II and III prolapse.
Perineal Procedures
Perineal procedures, such as the Altemeier procedure, involve removing the prolapsed rectum through the perineum (the area between the anus and the genitals). This approach is less invasive and may be suitable for elderly or high-risk patients.
Resection Rectopexy
Resection rectopexy combines rectal resection (removal of a portion of the rectum) with rectopexy. This procedure is typically reserved for patients with redundant (excess) rectal tissue.
Post-Surgical Care
Post-surgical care is crucial for a successful recovery. Patients may need to follow a specific diet, avoid heavy lifting, and engage in pelvic floor exercises to prevent recurrence.
Frequently Asked Questions
1. What is rectal prolapse?
Rectal prolapse occurs when part of the rectum protrudes through the anus, often leading to discomfort, bleeding, and difficulty with bowel movements.
2. What are the treatment options for rectal prolapse?
Treatment may involve surgical repair, including rectopexy, or non-surgical methods such as stool softeners and pelvic floor exercises.
3. How does rectal prolapse differ from hemorrhoids?
Rectal prolapse involves the rectum slipping out, while hemorrhoids are swollen blood vessels in the rectal or anal area.
4. What are the symptoms of rectal prolapse?
Symptoms include a protrusion of tissue from the anus, pain during bowel movements, and difficulty controlling bowel function.
5. What are the risk factors for rectal prolapse?
Risk factors include chronic constipation, aging, pelvic floor disorders, and previous surgeries, all contributing to weakened rectal support.
