Why Anal Fissures Occur?

Most authorities on anal fissures agree that anal fissures are mostly caused by trauma or stretching of anus and anal canal beyond its capacity/limit, especially by passage of hard and larger stool volume through anus. Some patients can even remember the bowel movement which caused the trauma leading to development of anal fissure. The particular bowel movement that leads to anal fissure is very painful and the pain continues after that for every bowel movement. The most common and important cause of hard stool is intake of low fiber diet. The diet with low fresh fruits and vegetable content contains little dietary fibers (commonly taken in developed countries) and cause constipation and anal fissure. In developed countries people consume low fiber diet and suffer from anal fissure more frequently than people of developing countries, where people eat more fresh vegetables, which contain high dietary fiber.

Repeated diarrheal episodes may also cause anal fissure. Among women, during childbirth the perineum (the skin in between anus and vagina) may be damaged due to trauma which may extent up to anoderm (the location where anal fissures develop) and cause anal fissure. Other possible causes of anal fissure include trauma due to use of rectal thermometer, ultrasound probes, endoscope etc. This is a less common cause of anal fissure, which require sufficient trauma to damage the anoderm.

There are some predisposing factors in causation of anal fissure, such as prior surgery in anus, which may cause stenosis (narrowing) of anal canal or may damage the anal sphincter. Narrowing of anal canal can easily lead to anal fissure, especially if patient consume low fiber diet which produce hard stool.

Generally anal fissure is not related to any particular occupation or no occupation is a predisposing factor for development of anal fissure.

Any anatomical abnormality such as hypertrophy or hyper tonicity of anal sphincter, may lead to anal fissure. The normal resting pressure is generally elevated in patients with anal fissure.
