An anal fissure is a tiny tear in the thin, moist tissue or mucosa that lines the anus.
An anal fissure may occur when you pass hard or large stools during a bowel movement. Anal fissures typically cause pain and bleeding with bowel movements. One may experience spasms in the ring of muscle at the end of anus / anal sphincter.
The usual causes of anal fissure include: passing large or hard stools, constipation and straining during bowel movements, chronic diarrhea, inflammation of the anorectal area, or another inflammatory bowel disease and even childbirth.
Most anal fissures get better with simple treatments, such as increased fiber intake or sitz baths. Some people with anal fissures may need relevant medication or, occasionally, a laser surgery here at VSLC.
