CAUSES OF ANAL FISSURE
WHAT IS AN ANAL FISSURE?
The anal canal is a short tube surrounded by muscle at the end of your rectum. The rectum is the bottom section of your colon large intestine. An anal fissure also called fissure-in-ano is a small rip or tear in the lining of the anal canal. Fissures are common, but are often confused with other anal conditions, such as hemorrhoids. Fissures are usually caused by trauma to the inner lining of the anus from a bowel movement or other stretching of the anal canal. This can be due to a hard, dry bowel movement or loose, frequent bowel movements. Patients with a tight anal sphincter muscle are more likely to develop anal fissures. Less common causes of fissures include inflammatory bowel disease, anal infections, or tumors. Anal fissures typically cause a sharp pain that starts with the passage of stool.

At times, the fissure can be deep enough to expose the muscle tissue underneath. In most cases, the tear heals on its own within four to six weeks. Certain treatments can promote healing and help relieve discomfort, including stool softeners and topical pain relievers.
