Anal Fissure vs. Fistula: Understanding the Key Differences

Many people confuse anal fissures and anal fistulas because both cause pain and discomfort in the anal region. However, they are completely different medical conditions that require different treatment approaches.

If you have ever experienced pain or discomfort during bowel movements and wondered whether it’s a fissure or a fistula, this blog will help you understand the differences, symptoms, causes, and treatments for both conditions — so you can seek the right medical help without delay.

What Is an Anal Fissure?

An anal fissure is a small tear or crack in the lining of the anus, often caused by passing hard stools or straining during bowel movements. Although it is a surface-level injury, it can be extremely painful because it exposes sensitive nerve endings.

Common Causes of Anal Fissure

• Passing dry or hard stools

• Chronic constipation or diarrhea

• Straining during bowel movements

• Tight anal muscles that make stool passage difficult

• Trauma or injury to the anal area (e.g., during childbirth)

• Less commonly, inflammatory bowel diseases like Crohn’s disease

Symptoms of Anal Fissure

• Sharp, burning pain during and after bowel movements

• Bright red blood on toilet paper or stool

• Swelling or inflammation around the anal area

• Visible small tear near the anal opening

• Painful muscle spasms

What Is an Anal Fistula?

An anal fistula is an abnormal tunnel that forms between the anal canal and the skin near the anus. It often develops after an infection in the anal glands, leading to an abscess that fails to heal completely.

Common Causes of Anal Fistula

• Untreated anal gland infection or abscess

• Chronic inflammatory bowel diseases (e.g., Crohn’s disease, ulcerative colitis)

• Injury to the anal region

• Rarely, chronic infections like tuberculosis or certain cancers

Symptoms of Anal Fistula

• Persistent pus or blood discharge near the anus

• Swelling and redness around the anal opening

• Pain that worsens while sitting or moving

• Irritation and skin damage from constant discharge

• Fever or general unwellness during infection

Anal Fissure vs. Fistula: Key Differences

Treatment Options for Anal Fissures

Most anal fissures heal naturally with proper care, but persistent cases may need medical or surgical intervention.

Common Treatments:

• Lifestyle changes – High-fiber diet, adequate water intake, avoiding straining

• Sitz baths – Sitting in warm water for 10–15 minutes, 2–3 times daily

• Topical ointments – To relax the anal sphincter and promote healing

• Surgery/Botox – For severe or chronic fissures to reduce muscle tension

Treatment Options for Anal Fistulas

Unlike fissures, fistulas rarely heal on their own and often require surgery.

Common Treatments:

• Antibiotics – To treat active infections

• Incision & drainage – For pus-filled abscesses before fistula repair

• Surgical procedures – Fistulotomy, seton placement, or minimally invasive laser treatment for quicker recovery

• Post-operative care – Maintaining hygiene and following wound care instructions

Prevention Tips

For Anal Fissures

• Maintain good anal hygiene
