Anal Fissure: causes and symptoms
An anal fissure is a condition defined by a small tear present in the thin, wet tissue lining the anus, which is the muscle aperture at the end of the digestive system responsible for stool expulsion. Straining or large stools during bowel movements and constipation are among the most common causes of anal fissures.
Anal fissures can affect people of all ages.. Fortunately, most anal fissures can be easily treated through simple interventions such as increasing fiber intake or warm-water baths. However, in some cases, medication or surgery may be necessary to treat anal fissures.
Symptoms of Anal Fissures
The most common anal fissure symptoms include:
- Pain during defecation: Anal fissures often cause sharp pain during bowel movements.
- Pain after bowel movements: This discomfort can persist for several hours.
- Visible skin crack: A noticeable tear around the anus, sometimes with a visible crack.
- Presence of bright red blood: Blood may appear on toilet paper or Bleeding While Passing Stool
When to see a doctor?

Risk Factors for Anal Fissures
The following factors may increase the chances of having an anal fissure:
- Constipation: Constipation of tearing is increased by straining during bowel motions and passing hard stools.
- Childbirth: Women are more likely to develop anal fissures after giving birth.
- Crohn’s disease: Chronic intestinal inflammation is caused by this inflammatory bowel disease. This could make the anal canal lining more prone to tears.
- Age: Anal fissures can develop at any age but are more frequent in infants and middle-aged adults.
Complications of Anal Fissures
Anal fissure complications may include:
- Failure to heal: An anal fissure that does not heal after eight weeks is considered chronic and may require additional treatment.
- Recurrence: After you’ve had an anal fissure, you’re more prone to have another one.
- Extended tears: In some cases, fissures may extend to the muscles around the anus, making healing more difficult and causing prolonged pain.
Diagnosis of Anal Fissures
The doctor will most likely ask about the medical history and perform a physical exam, which will include a gentle digital examination of the anal region. The tear is frequently noticeable. This exam is usually all that is required to identify an anal fissure.
- Anoscopy: A tool inserted into the anus to examine the area.
- Flexible sigmoidoscopy: A Flexible sigmoidoscopy procedure to examine the sigmoid colon with a camera.
- Colonoscopy: A deeper examination of the colon, particularly for those over 45 or with symptoms like abdominal pain or diarrhea.
Treatments for Anal Fissures
In most cases, anal fissure treatment heals within a few weeks with proper home care. Here’s how you can manage it:
- Increase fiber intake: A high-fiber diet helps soften stools and prevents straining.
- Sitz baths: Soaking the warm water for 10 to 20 minutes, especially after bowel movements, can relax the sphincter and promote healing.
- Topical treatments: Over-the-counter creams like Xylocaine (lidocaine) can relieve pain.
If home care doesn’t provide relief, medical treatments may include:
Nonsurgical treatments
Nitroglycerin (Rectiv): This medication can improve blood flow to the fissure and relax the anal sphincter, aiding healing.
Onabotulinumtoxin A: Injecting botox can paralyze the anal sphincter temporarily, reducing pain and spasms.
Surgical treatments
Anal Fissure Surgery: For chronic fissures that don’t heal with other treatments, surgery may be needed. The most common procedure is lateral internal sphincterotomy (LIS), where part of the internal anal sphincter muscle is cut to relieve pressure and promote healing. Although effective, surgery carries a small risk of incontinence.
