Anal Fissure: An Overview
What is an Anal Fissure?
An anal fissure is a minor tear in the delicate, moist lining of the anus—the muscular end of the digestive tract where stool leaves the body. It often results from constipation, straining, or passing hard or large stools. Symptoms typically include pain and bleeding during bowel movements, and possibly muscle spasms in the anal sphincter.
Who is Affected?
While common in infants, anal fissures can occur at any age. Most heal with simple measures like increased fiber intake or warm baths. Some cases may require medication or surgery.
Recognizing Symptoms
- Pain during and after bowel movements
- Bleeding: Bright red blood on stool or toilet paper
- Skin Changes: A visible tear or skin tag near the anus
When to Consult a Doctor
Consult a healthcare provider if you experience pain or bleeding during bowel movements.
Causes and Risk Factors
Common Causes
- Large or hard stools
- Chronic constipation and straining
- Persistent diarrhea
- Anal intercourse
- Childbirth
Less Common Causes
- Inflammatory bowel diseases like Crohn’s disease
- Anal cancer
- HIV
- Tuberculosis
- Syphilis
Risk Factors
- Constipation: Increases the risk of tears
- Childbirth: More common postpartum in women
- Chronic Inflammation: Conditions like Crohn’s disease
- Age: Prevalent in infants and middle-aged adults
Potential Complications
- Chronic Fissures: Those not healing within eight weeks
- Recurrence: Likelihood of experiencing additional fissures
- Muscle Damage: Tears extending to the internal anal sphincter, complicating healing
Prevention Strategies
Prevent anal fissures by avoiding constipation or diarrhea through a diet rich in fiber, adequate hydration, and regular exercise to minimize straining during bowel movements.
