Comprehensive Guide to Anal Fissures
An anal fissure is a small tear in the thin, moist tissue (mucosa) that lines the anus. This common condition can cause significant pain and bleeding during and after bowel movements. Understanding the causes, symptoms, and treatment options is crucial for effective management and prevention. This guide provides detailed information to supplement your knowledge.
What Causes an Anal Fissure?
The primary cause of most anal fissures is trauma to the anal canal. This typically happens from:
- Passing large, hard, or dry stools (constipation).
- Straining during bowel movements.
- Chronic diarrhea.
- Childbirth, which can cause trauma to the perineum and anal area.
- Less common causes include inflammatory bowel disease (like Crohn’s disease), anal cancer, or other infections.
High tension in the internal anal sphincter muscle can also contribute to the development of fissures and impair their healing by reducing blood flow to the area.
Key Symptoms of an Anal Fissure
The symptoms of an anal fissure are often distinct and can significantly impact quality of life. The most prominent signs include:
- Severe, sharp pain during a bowel movement, often described as feeling like passing broken glass.
- A lingering deep, burning pain or ache that can last for several hours after a bowel movement.
- Bright red blood on the stool or on toilet paper after wiping.
- A visible crack or tear in the skin around the anus.
- A small lump or skin tag (known as a sentinel pile) next to the fissure, which is common in chronic cases.

Diagnosis Process
Diagnosing an anal fissure is usually straightforward. A healthcare provider can often diagnose it based on a description of symptoms and a gentle visual inspection of the anal area. In most cases, a digital rectal exam or anoscopy is avoided initially to prevent further pain. If the fissure is in an unusual location (not in the posterior or anterior midline) or if it doesn’t heal with initial treatment, further investigation may be needed to rule out underlying conditions like Crohn’s disease.
Treatment: From Conservative to Surgical
The goal of treatment is to relieve pain and pressure on the anal canal, allowing the tear to heal. Treatment strategies vary based on whether the fissure is acute (present for less than 6-8 weeks) or chronic.
- First-Line Conservative Treatment: Increasing dietary fiber and fluid intake to soften stools, taking warm water baths (sitz baths) to relax the sphincter muscle, and using topical anesthetics like lidocaine can heal most acute fissures.
- Medical Treatment: For chronic fissures, medications are often used to relax the anal sphincter muscle and improve blood flow. These include topical nitroglycerin ointment or calcium channel blocker creams (like diltiazem or nifedipine).
- Botox Injections: Botulinum toxin (Botox) can be injected into the internal anal sphincter to temporarily paralyze the muscle, promoting healing.
- Surgical Treatment: The gold standard for chronic fissures that don’t respond to other treatments is a procedure called Lateral Internal Sphincterotomy (LIS). This involves making a small incision in the internal anal sphincter muscle to reduce spasm and pressure.
Preventing Recurrence
Once a fissure has healed, preventing its return is key. The most effective prevention strategy is to avoid constipation and straining. This can be achieved by maintaining a high-fiber diet (25-35 grams per day), drinking plenty of water, and establishing regular bowel habits. Promptly treating any bouts of diarrhea is also important.
Understanding Acute vs. Chronic Fissures
An acute fissure appears as a fresh, superficial tear, similar to a paper cut. With proper care, it often heals within a few weeks. A chronic fissure, lasting more than 8 weeks, develops deeper into the muscle layer and may feature a sentinel pile at its outer edge and hypertrophied anal papilla at its inner edge. Chronic fissures are less likely to heal on their own and typically require more intensive medical or surgical intervention.
Frequently Asked Questions
Can an anal fissure heal on its own?
Yes, many acute anal fissures can heal on their own within a few weeks, especially with simple home care like increasing fiber and fluid intake, and taking sitz baths. Chronic fissures are less likely to heal without medical intervention.
Is bleeding from an anal fissure dangerous?
The bleeding from an anal fissure is typically a small amount of bright red blood and is not dangerous. However, any rectal bleeding should be evaluated by a healthcare provider to rule out more serious conditions.
What is a sitz bath?
A sitz bath involves sitting in a few inches of warm water for 10-15 minutes, two to three times a day, especially after bowel movements. This helps to relax the anal sphincter muscle, improve blood flow, and relieve pain, which aids in the healing process.
What is the main risk of the LIS surgery?
The primary risk of a Lateral Internal Sphincterotomy (LIS) is a small but permanent degree of incontinence to gas or liquid stool. While the surgery has a very high success rate (over 90%) for healing fissures, this potential side effect is why it’s typically reserved for cases that fail conservative and medical treatments.
