Anal Fissure: Causes, Symptoms and Treatment Options

What is Anal Fissure?

An anal fissure is a small tear in the delicate lining of your anus. This tiny cut also known as fissure in ano, causes sharp pain, burning and bleeding when you pass stool. It is a common condition that can happen to people of all ages. It is often triggered by constipation and straining during bowel movements.

How do Anal Fissures Affect the Body?

Your anus sits at the end of your digestive tract, where stool leaves your body. A strong ring of muscle called the anal sphincter surrounds this opening, helping you control bowel movements.

When a fissure in the anus develops, it creates an open wound that exposes the underlying muscle. This exposure causes painful muscle spasms every time you have a bowel movement. The pain can be sharp and burning, often lasting several hours after you finish. 

These spasms create a bigger problem. They reduce blood flow to the torn area, making it harder for your body to heal naturally. This is why some fissures become chronic and refuse to heal on their own.

Anal fissure symptoms become worse because passing stool reopens the tear repeatedly.  The whole process disrupts your normal routine. The pain makes you dread using the toilet, which often leads to holding in the stool. This creates harder stools, more straining, and a cycle that makes the fissure worse.

Types of Fissures

Anal fissures are classified into two types based on how long they've been present and what changes have occurred in the tissue.

Acute Anal Fissure

An acute anal fissure is a recent tear that causes sharp, burning pain during and after bowel movements—often described as passing broken glass. The pain can last from minutes to hours. Most acute fissures heal on their own within weeks.

Chronic Anal Fissure

A chronic anal fissure lasts over six weeks, with thickened edges, a sentinel pile, and sometimes visible muscle at the base. Pain is more persistent, with frequent spasms. It usually won’t heal with home care alone and needs medical attention.

Here is a table to show the difference between the two types of anal fissure:

Feature Acute Anal Fissure Chronic Anal Fissure
Duration Recent tear, present for less than 6 weeks Persists for more than 6–8 weeks
Cause Usually due to passing hard or large stools, diarrhea Poor healing from repeated or prolonged strain, diarrhea
Pain Sudden, sharp, burning pain during or after bowel movement Persistent, less sharp pain; may interfere with daily activities
Appearance Fresh tear with smooth edges Thickened, scarred edges; possible sentinel skin tag
Muscle Spasm Present but usually temporary Ongoing internal sphincter spasm restricts blood flow
Healing Response Heals naturally in most cases with simple care Difficult to heal without medical intervention
Treatment Diet changes, hydration, sitz baths, medication Fissure medicine, minor surgical procedures (if needed)
Prognosis Excellent with early management Requires targeted therapy to break the cycle of non-healing

 

Causes of Fissures

Understanding what causes anal fissures helps you take steps to prevent this painful condition from developing or recurring. The main causes of anal fissure include:

  • Hard or large stools: When you're constipated, passing hard stools forces your anal lining to stretch beyond its limits. This stretching tears the thin tissue, creating a fissure. The anal mucosa is much more delicate than regular skin, making it prone to injury.
  • Straining during bowel movements: Excessive pushing increases pressure in your anal canal. This pressure can cause existing small tears to worsen or create new ones in the anal lining.
  • Chronic diarrhea: Frequent loose stools irritate and inflame your anal canal. This constant irritation weakens the tissue, making it more likely to tear even with normal bowel movements.
  • Childbirth trauma: Vaginal delivery can stretch and damage the anal area, especially during prolonged labour or when delivering larger babies. This makes new mothers more vulnerable to developing fissures.
  • Inflammatory bowel diseases: Conditions like Crohn's disease cause ongoing inflammation in your intestines. This chronic inflammation weakens your anal lining and increases your risk of developing fissures.
  • Physical trauma: Anal intercourse, medical procedures, or insertion of foreign objects can directly injure the anal lining and create tears.
  • Poor hygiene or infections: Infections or irritation from harsh cleaning products can inflame your anal skin, making it more susceptible to tearing.
  • Age-related factors: Infants and adults between the ages of 40 and 60 are more prone to anal fissures because their anal tissue tends to be more delicate or less elastic. In infants, the tissue is still developing, while in middle-aged adults, reduced blood flow and natural aging can make the skin more susceptible to tearing.
Understanding these causes of anal fissure empowers you to make dietary and lifestyle adjustments that protect your anal
health.

What are the Risk Factors for Anal Fissure?

Certain conditions and habits increase your likelihood of developing a fissure in ano. Recognising these risk factors helps you make lifestyle changes that can prevent this painful condition. Key risk factors include:
  • Constipation and straining: This is the primary risk factor. When you strain to pass hard stools, you create excessive pressure that can tear your anal lining.
  • Age vulnerability: Infants have naturally delicate anal tissue, whilst middle-aged adults experience changes in tissue elasticity that make fissures more likely.
  • Recent childbirth: Women who've had vaginal deliveries face a higher risk due to stretching and potential trauma to the anal area during birth.
  • Inflammatory bowel diseases: Crohn's disease and similar conditions create chronic inflammation that weakens your anal tissues over time.
  • History of anal trauma: Previous injuries or medical procedures in the anal area can create scar tissue that's more prone to tearing.
  • Poor bowel habits: Delaying bowel movements when you feel the urge allows stools to become harder and more difficult to pass.
  • Low-fibre diet: Diets lacking adequate fruits, vegetables, and whole grains lead to harder stools that require more straining to pass

Symptoms of Anal Fissures

Recognising anal fissure symptoms early helps you seek appropriate treatment before the condition becomes chronic. The symptoms can significantly impact your daily comfort and quality of life. Common symptoms of fissure include:
  • Severe pain during bowel movements: You'll experience sharp, intense pain that many describe as feeling like passing glass or knives. This pain occurs during defecation and can last for minutes to hours afterwards.
  • Bright red bleeding: You'll notice fresh blood on toilet paper, in the toilet bowl, or on the surface of your stool. Unlike other conditions, fissure bleeding is typically bright red and occurs with bowel movements.
  • Anal itching and irritation: The area around your anus may feel itchy, burning or irritated due to inflammation and the body's healing attempts.
  • Visible tear or skin tag: You might see a small crack in the anal opening or notice a small piece of skin (sentinel pile) near the fissure site.
  • Anal muscle spasms: Your anal sphincter muscle may go into spasm, causing additional cramping and discomfort that can persist between bowel movements.
Important distinctions:

The pain from fissures tends to be sharp and episodic, occurring mainly with bowel movements. This differs from hemorrhoid pain, which can be more constant and throbbing.

In infants, symptoms of fissure may appear as unusual fussiness during nappy changes and blood streaks in their stool.

These symptoms often worsen with poor dietary habits or dehydration, making early recognition and treatment for fissures essential.

How is Fissure Diagnosed?

Proper diagnosis of a fissure requires a thorough medical evaluation to distinguish it from other anal conditions and determine the best treatment approach. Let's take a look at the pointers below:

Symptom Review

Your doctor will ask detailed questions about your pain patterns, bleeding, bowel habits, and any previous anal problems. This conversation helps identify when symptoms started and what might be causing them.

Physical Examination

The doctor performs a gentle visual inspection of your anal area to look for visible tears, swelling, or skin tags. Light palpation may be done to check muscle tone and assess tenderness levels.

Endoscopy Procedures

Your doctor may also do some endoscopic exams to ensure accurate identification and appropriate fissure treatment planning

Anoscopy

A small, lighted tube is gently inserted into your anus to provide a clear view of the anal canal and identify fissure location and severity.

Sigmoidoscopy

This examines your lower colon and rectum if deeper inflammation is suspected, particularly useful when inflammatory bowel disease might be present.

Colonoscopy

A comprehensive examination of your entire colon is recommended when bleeding persists or other intestinal diseases need to be ruled out.

Treatment for Anal Fissures

Fissure treatment focuses on breaking the painful cycle that prevents healing. When you have an anal fissure, the torn tissue struggles to repair itself because muscle spasms and pain during bowel movements keep reopening the wound. Treatment options range from simple home care to medical interventions, all aimed at reducing pain, softening stools, and allowing natural healing to occur.

Home Remedies

Simple home remedies can provide significant relief for fissure symptoms and promote natural healing. These approaches focus on reducing strain during bowel movements, keeping stools soft, and creating conditions that support tissue repair. Many of these remedies align well with traditional Indian practices and can be easily incorporated into daily routines. Key home remedies include:

Remedy Details
Increase dietary fibre intake Add more whole grains, fruits like papaya and guava, vegetables such as spinach and carrots, and legumes to your meals. Aim for 25–30 grams of fibre daily to soften stools naturally. Fibre absorbs water and creates bulk, making bowel movements easier and reducing trauma to the fissure in anus.
Stay well hydrated Drink 2–3 litres of water daily, including herbal teas and buttermilk. Proper hydration keeps stools soft and prevents the straining that worsens anal fissure symptoms. Water works with fibre to create the right stool consistency for comfortable passage.
Take warm sitz baths Soak the affected area in warm water for 10–15 minutes, especially after bowel movements. This relaxes the anal muscles, improves blood flow to promote healing, and provides immediate pain relief. The warmth reduces muscle spasms that often accompany fissures.
Avoid straining during bowel movements Respond to the urge promptly and don't spend long periods on the toilet. Use a footstool to elevate your feet, which improves the angle for easier stool passage. Straining increases pressure on the fissure and delays healing.
Maintain gentle anal hygiene Clean the area with plain water after bowel movements and pat dry gently. Avoid harsh soaps or fragranced wipes that can irritate the sensitive tissue. Water-based cleaning helps prevent infection whilst being gentle on healing skin.
Use natural stool softeners Psyllium husk (isabgol) mixed with water creates bulk and softness, reducing the mechanical trauma during defecation. Take it regularly to maintain a consistent stool texture.
Moderate spicy foods Whilst healing, reduce very hot spices that may increase discomfort during bowel movements. This gives the fissure time to heal without additional irritation.

 

Medications

Fissure medicines focus on pain relief, muscle relaxation, and supporting the healing process through both symptom management and addressing underlying causes.

Over-the-counter Medication

OTC fissure medicine aims to break the pain-spasm cycle. These treatments can be broadly categorised into the following categories:

  • Topical anaesthetics like lidocaine numb the area during bowel movements, providing immediate pain relief. Some creams contain vasodilators like nitroglycerin, which relax the internal anal sphincter muscle and increase blood flow to promote healing. However, these are temporary solutions which do not provide proper treatment and are not ideal for long term use, as they can cause headache, dizziness in some users due to their effects on blood vessels.
  • Stool softeners such as docusate sodium prevent the hard stools that can reopen healing fissures. Bulk-forming fibre supplements like psyllium husk help maintain soft stools consistently, preventing further trauma to the healing fissur

Plant-based Medication

Plant-based treatments offer a gentle approach to fissure treatment by reducing inflammation, easing pain, and supporting your digestive health naturally. Traditional herbal remedies have been used for generations to heal anal conditions safely. Healing Hands has developed best home remedy for anal fissure treatment FissureKit specific plant-based medicines kit that combines traditional wisdom with modern safety standard

 Surgery Options

When an anal fissure becomes chronic—lasting more than 6-8 weeks—and doesn't respond to conservative treatment, surgical intervention may be necessary. Surgery aims to reduce muscle spasm, improve blood flow to the fissure site, and create conditions for proper healing. The choice of procedure depends on fissure severity, patient health, and surgeon expertise. At Healing Hands Clinic we have specialised well trained surgeons to treat patients with such conditions.

 Partial Lateral Internal Sphincterotomy (PLIS)

It represents the gold standard surgical treatment for fissure. The surgeon makes a small, controlled cut in the internal anal sphincter muscle to reduce spasm and pressure. This improved muscle relaxation allows better blood circulation to reach the fissure, promoting natural healing. Success rates exceed 90%, with most patients experiencing significant pain relief within days. The procedure is typically done as day surgery, and patients can return to normal activities within a week with proper care.

Laser Surgery

It offers a minimally invasive alternative using focused laser energy to treat the fissure area. The laser reduces sphincter spasm whilst promoting tissue healing through controlled thermal effects. Patients experience less post-operative pain and faster recovery compared to traditional surgery. However, this option requires specialised equipment and trained surgeons, making it less widely available in many Indian centres. We at Healing Hands Clinic have specialised well trained surgeons to treat patients with chronic anal fissure.

Botulinum (Botox) Injection

It provides a non-surgical approach by temporarily relaxing the internal anal sphincter muscle. The injection is given in an outpatient setting, directly into the muscle causing spasm. Effects typically last 3-6 months, during which the reduced muscle tension allows the fissure to heal naturally. Some patients may need repeat injections, but this option appeals to those wanting to avoid surgical cuts. Best way to treat fissure is to start early treatment with proven effective fissure medicines.

Lord's Dilatation

This involves gentle manual stretching of the anal canal under anaesthesia to reduce sphincter pressure. This older technique is now less commonly used due to higher risks of incontinence compared to more precise modern methods.
It may still be considered in specific cases where other surgical options aren't suitable, but most surgeons prefer sphincterotomy for its predictable results and lower complication rates.

When to See a Doctor

While many fissure cases heal with home care and early treatment with medicines, certain symptoms require immediate medical attention. You should consult a doctor if you experience the anal fissure symptoms for more than 6 to 8 weeks such as severe pain that lasts for hours after bowel movements, making it difficult to sit or walk comfortably.

Watch for these warning signs:
  • Bright red blood on toilet paper or in stools that persist beyond 6 – 8 weeks
  • A visible crack or tear around your anal opening
  • Symptoms of fissure continuing for more than 6 – 8 weeks despite trying home remedies
  • Fever, pus discharge, or swelling around the anal area
  • Pain so intense that you avoid bowel movements entirely
Quick Tip: Don't let embarrassment delay your visit. Doctors see these conditions regularly and can offer effective solutions.

Early consultation helps rule out serious conditions like Crohn's disease or anal cancer. Many people in India delay seeking care due to stigma, but this often worsens symptoms and leads to chronic fissure in the anus. Your doctor can recommend proper treatment for fissure options, including topical medications or Ayurvedic medicine for fissure that speed healing naturally.
The sooner you seek help, the easier it becomes to manage your condition and prevent complications.

Complications from Untreated Anal Fissures

Ignoring a fissure can lead to serious complications that significantly impact your daily life. The most common issue is chronic fissure formation, where the tear deepens and fails to heal after eight weeks, causing persistent pain and bleeding. Here's what can happen without proper fissure treatment:

  • Anal sphincter spasm: The muscle around your anus tightens to protect the area, reducing blood flow and preventing natural healing.
  • Infection: Bacteria can enter the tear, potentially causing abscesses or fistulas that may require surgical intervention.
  • Skin tags: Chronic fissures often develop small skin flaps near the tear, creating hygiene challenges and discomfort

In India, delayed treatment due to embarrassment often worsens these fissure complications. The anal sphincter spasm creates a cycle where pain leads to muscle tension, which further reduces healing. This is why early intervention with proper medicines for fissure or lifestyle changes is crucial.
Without treatment, you might eventually need anal fissure surgery, which could have been avoided with timely care with proven medicines and appropriate home management.

Your Path to Healing: Managing Fissures Effectively

Understanding anal fissure symptoms and acting quickly makes all the difference in your healing journey. Persistent pain or bleeding shouldn't be ignored, as timely care prevents complications and brings faster relief.
Treatment for fissure ranges from simple dietary changes and warm baths to prescribed medications when needed. The key is consistency with care and not waiting until the problem worsens.
For those seeking gentle, effective support, consider exploring proven solutions that combine traditional wisdom with modern understanding. Healing Hands FissureKit offers thoughtful approaches designed specifically for Indian lifestyles, helping you regain comfort naturally.
Remember, early intervention empowers you to take charge of your digestive health with confidence. Your comfort matters, and effective relief is within reach.
