Yes—constipation is the most common cause of an anal fissure. Passing hard, large stools stretches and tears the delicate lining of the anal canal, creating a painful crack. This tear then triggers a spasm-pain cycle that makes each bowel movement harder to heal. In this article, we explain how constipation causes fissures, the warning signs to watch for, when to see a doctor, and the proven treatment and prevention options available at Lux Hospitals. Understanding this link helps you act early and avoid a chronic, recurring problem.
What Is an Anal Fissure?
An anal fissure is a small tear or crack in the thin lining of the anal canal. It is one of the most common causes of sharp anal pain.
Fissures can be acute (recent) or chronic (lasting over six weeks). Both types are highly treatable with the right care.
Key features include:
- A tear in the anal lining
- Sharp pain during bowel movements
- Bright red blood on tissue
- Can be acute or chronic
- Very common and treatable

How Constipation Causes an Anal Fissure
Constipation is the leading cause of anal fissures. When stools become hard and dry, they stretch the anal canal beyond its natural limit.
Straining to pass a large stool adds pressure that tears the delicate skin, creating a fissure.
Here is how the link works:
- Hard stools overstretch the anal lining
- Straining raises pressure inside the canal
- The lining cracks under the strain
- Repeated episodes deepen the tear
- Chronic constipation prevents healing
If you struggle with recurring hard stools, consult the colorectal team at Lux Hospitals.
The Pain-Spasm Cycle Explained
Once a fissure forms, it triggers a vicious cycle that keeps it from healing. The tear causes the internal anal muscle to tighten in spasm.
This spasm reduces blood flow to the area and increases pain during each bowel movement.
The cycle typically involves:
- Tear causes muscle spasm
- Spasm cuts blood supply
- Poor blood flow slows healing
- Pain leads to stool-holding
- Harder stools worsen the tear

Symptoms to Watch For
Fissures produce distinct, recognisable symptoms. The most telling sign is sharp pain during and after passing stool.
Many patients describe it as passing broken glass, followed by hours of throbbing discomfort.
Symptoms may include:
- Sharp pain during bowel movements
- Bright red blood on toilet paper
- Burning or aching afterward
- A visible tear or skin tag
- Itching around the anus
Other Causes of Anal Fissures
While constipation is the main culprit, fissures can arise from other conditions too. Anything that irritates or stretches the anal canal may cause a tear.
Digestive disorders and certain habits also raise the risk.
Other causes include:
- Chronic diarrhoea and loose stools
- Childbirth and vaginal delivery
- Inflammatory bowel disease
- Tight anal sphincter muscles
- Anal trauma or examinations
Who Is Most at Risk?
Anyone can develop a fissure, but some groups are more vulnerable. Poor diet and irregular bowel habits are major contributors.
Conditions affecting bowel movements also increase risk considerably.
You may be at higher risk if you have:
- Chronic constipation or straining
- A low-fibre, low-water diet
- Recent childbirth
- Irritable bowel syndrome
- A sedentary lifestyle
Reduce your risk with expert guidance from Lux Hospitals.
Complications of Untreated Fissures
Ignoring a fissure can lead to lasting problems. An acute tear can become chronic and far harder to heal.
Persistent fissures may also give rise to other anal conditions over time.
Possible complications include:
- Chronic, non-healing fissure
- Skin tags near the tear
- Development of an anal fistula
- Ongoing pain and bleeding
- Recurring infection or abscess
How to Prevent Fissures From Constipation
Preventing constipation is the best way to avoid fissures. Simple diet and lifestyle changes make a big difference.
Soft, regular stools protect the anal lining from tearing.
Helpful prevention steps include:
- Eat more fibre daily
- Drink plenty of water
- Exercise regularly
- Never delay bowel urges
- Avoid excessive straining

How Fissures Are Diagnosed
Diagnosis is usually quick and based on your symptoms. A specialist gently examines the anal area to confirm the tear.
In some cases, further tests rule out other conditions like piles or inflammatory bowel disease.
Diagnosis may involve:
- Review of symptoms and history
- Gentle visual examination
- Digital rectal exam if tolerated
- Anoscopy for a clearer view
- Tests to rule out other causes
