Treatment and Management of Anal Fissure[sg_popup id="977" event="click" wrap="span"]
An anal fissure is a small tear, cut or an ulcer (an open sore) in the thin moist tissue (mucosa) lining the lower rectum or the anus. These can occur at any age but are highly common in young infants. The risk for anal fissure decreases as age increases. Majority of cases of anal fissure can be treated with appropriate home treatment and usually heal within days to weeks. These are called acute anal fissures. In contrast, chronic anal fissures occur for more than six weeks and may require surgery.
Anal fissures occur in the specialized tissue called the anoderm, which lines the anus and the anal canal. The anoderm contains no hair, sweat glands and sebaceous glands, however, it is rich of nerve endings, thus causing extreme pain when it has a tear. Trauma to the anus causes anal fissures.
What Causes Anal Fissure?
It is believed that excessive tension in the sphincter muscles controlling the anus can lead to anal fissure. The following can lead to too much tension in the muscular rings of the anus:
- Passing large, hard stools frequently that stretches the anal canal
- Constipation and cannot pass hard stools even with repeated attempts
- Chronic diarrhoea
- Reduced blood flow to the area
- After childbirth
- Rectal foreign body
- Anal intercourse
- Crohn’s disease
- Inflammatory bowel disease
What are the Symptoms of Anal Fissure?
Young infants may not always be able to articulate if they are feeling pain when passing stools. Sharp, burning and stinging pain during bowel movement is the most common symptom of anal fissures. The following symptoms are usually present in combination and may appear abruptly or gradually:
- Bleeding after passing bowels
- On the outside of the stool
- On baby wipes or tissue paper
- Bloody diarrhoea
- Yellowish discharge
- Evident crack in the skin when the area is slightly stretched, usually in the middle
- Abdominal pain
- Weight loss

- Eat a high fibre diet to soften stools and reduce pain during bowel movements. Drink plenty of water and other fluids.
- Avoid constipation as it may prolong healing time.
