Anal fissures are caused by trauma to the anus and anal canal. The cause of the trauma usually is a bowel movement, and many people can remember the exact bowel movement during which their pain began. The fissure may be caused by a hard stool or repeated episodes of diarrhea.
CAUSES OF ANAL FISSURE. 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.
