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.
Less often, having anal sex or putting things into your anus can overstretch the skin and cause a fissure. Too much pressure, tight anal sphincter muscles, and poor blood supply to your anus may lead to their development and poor healing. Anal fissures don't usually give way to more serious problems. They donât cause cancer. But they can be very uncomfortable. To help these fissures heal and keep them from coming back: 1  Eat a healthy diet that has plenty of fiber. 2  Stay well-hydrated.
