Proctitis
Proctitis is an inflammation of the lining of the rectum, the final segment of the large intestine. This condition can cause discomfort, pain, and various other symptoms that can significantly impact one's quality of life. Understanding the causes, symptoms, diagnosis, and treatment options for proctitis is crucial for managing this condition effectively.
What is Proctitis?
Proctitis is characterised by inflammation of the rectal mucosa. This inflammation can result from various factors, including infections, autoimmune diseases, and radiation therapy. Depending on the underlying cause, proctitis can be classified into different types, each with its unique set of symptoms and treatments.
Types of Proctitis
Infectious Proctitis
Bacterial, viral, or parasitic infections cause infectious proctitis. Common culprits include sexually transmitted infections (STIs) such as gonorrhea, chlamydia, and herpes. Other infections, such as shigella or campylobacter, can also lead to proctitis.

Get A Second OpinionRadiation Proctitis
Radiation proctitis occurs as a side effect of radiation therapy, primarily for cancer treatment in the pelvic region. The radiation can damage the rectal mucosa, leading to inflammation and other symptoms.
Autoimmune Proctitis
Autoimmune proctitis is often associated with inflammatory bowel diseases (IBD) such as Crohn's disease or ulcerative colitis. In these cases, the body's immune system mistakenly attacks the rectal tissue, causing inflammation.
Ischemic Proctitis
Ischemic proctitis is a result of reduced blood flow to the rectum, often due to conditions like atherosclerosis or blood clots. This reduced blood flow can lead to inflammation and tissue damage.
Symptoms of Proctitis
The symptoms of proctitis can vary depending on the underlying cause and severity of the inflammation. Common symptoms include:
- Rectal Pain: A consistent or intermittent pain in the rectal area.
- Rectal Bleeding: Blood in the stool or on toilet paper after a bowel movement.
- Diarrhea: Frequent, loose stools.
- Tenesmus: A constant feeling of needing to have a bowel movement, even when the rectum is empty.
- Mucus Discharge: The presence of mucus in the stool.
- Constipation: Difficulty passing stools or infrequent bowel movements.
- Abdominal Pain: Generalized or localised pain in the lower abdomen.
Causes of Proctitis
Infections
Infectious agents are a significant cause of proctitis. These can include:
- Bacteria: Such as Neisseria gonorrhoeae, Chlamydia trachomatis, and Treponema pallidum.
- Viruses: Including herpes simplex virus (HSV) and cytomegalovirus (CMV).
- Parasites: Such as Entamoeba histolytica.
Radiation Therapy
Radiation therapy for cancers in the pelvic area, such as prostate or cervical cancer, can damage the rectal lining, leading to radiation proctitis.
Autoimmune Disorders
Conditions like Crohn's disease and ulcerative colitis can cause chronic inflammation of the rectum as part of a broader inflammatory process in the gastrointestinal tract.
Reduced Blood Flow
Conditions that compromise blood flow to the rectum, such as atherosclerosis, can result in ischemic proctitis. This type of proctitis is less common but can be severe.
Other Causes
- Trauma: Physical injury to the rectum.
- Medications: Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), can cause rectal inflammation.
- Chemicals: Exposure to irritants or chemicals can also lead to proctitis.
Diagnosis of Proctitis
Diagnosing proctitis involves a combination of medical history, physical examination, and diagnostic tests. A healthcare provider will typically perform the following:
Medical History and Physical Examination
The healthcare provider will ask about symptoms, sexual history, and any recent medical treatments or procedures. A physical examination, including a digital rectal exam, may also be conducted.
Laboratory Tests
- Stool Tests: To detect infections or blood in the stool.
- Blood Tests: To identify signs of infection, inflammation, or autoimmune disorders.
Imaging Studies
- Sigmoidoscopy: A flexible tube with a camera is inserted into the rectum to visualise the rectal lining and obtain tissue samples.
- Colonoscopy: A similar procedure that examines the entire colon and rectum.
Biopsy
A tissue sample taken during a sigmoidoscopy or colonoscopy can be analysed to determine the presence of inflammation, infection, or other abnormalities.
Complications of Proctitis
If left untreated, proctitis can lead to several complications, including:
- Chronic Pain: Persistent pain and discomfort in the rectal area.
- Ulcers: Open sores in the rectal lining that can bleed and become infected.
- Strictures: Narrowing of the rectum due to scar tissue formation.
- Fistulas: Abnormal connections between the rectum and other organs, such as the bladder or vagina.
- Increased Risk of Colorectal Cancer: Particularly in cases of chronic inflammation, such as with IBD-associated proctitis.
Treatment of Proctitis
The treatment of proctitis depends on the underlying cause and severity of the condition. Common treatment options include:
Medications
- Antibiotics: For bacterial infections.
- Antivirals: For viral infections, such as herpes.
- Anti-inflammatory Drugs: To reduce inflammation, including corticosteroids and aminosalicylates.
- Immunosuppressants: For autoimmune proctitis associated with IBD.
Radiation Therapy Management
For radiation proctitis, treatment options may include:
- Anti-inflammatory Medications: To reduce inflammation and pain.
- Endoscopic Procedures: Such as argon plasma coagulation to treat bleeding and ulcers.
- Hyperbaric Oxygen Therapy: To promote healing of the damaged rectal tissue.
Lifestyle and Dietary Changes
- Dietary Adjustments: Avoid foods that can irritate the rectum, such as spicy or acidic foods.
- Hydration: Drinking plenty of fluids to prevent dehydration, especially in cases of diarrhoea.
- Fiber Intake: Increasing dietary fiber to manage constipation and promote healthy bowel movements.

Surgical Intervention
In severe cases of proctitis, surgical intervention may be necessary. This can include procedures to remove damaged tissue, repair fistulas, or address strictures.
Proctitis is a condition characterised by inflammation of the rectal lining, leading to various uncomfortable and potentially severe symptoms. Understanding the different types, causes, symptoms, and treatment options for proctitis is essential for effective management and improved quality of life.
If you suspect you have proctitis or are experiencing symptoms, it is crucial to seek medical attention for a proper diagnosis and tailored treatment plan. Early intervention can help prevent complications and ensure the best possible outcomes.
