An anal fissure is a cut or tear in the lining of the anus.
More to Know
An anal fissure can occur when someone passes a large or hard stool (poop), which
stretches the lining of the anus until it tears. It also can happen when frequent
diarrhea irritates the lining.
An anal fissure can cause pain or itching in the area, especially during and
after bowel movements. You may also see blood on the stool, baby wipes, or toilet
tissue.
In infants, anal fissures are very common and tend to heal completely with basic
care, including soaks and ointment. In older kids and teens, the cuts can take several
weeks or longer to heal and sometimes tear open again.

Keep in Mind
Preventing constipation
and keeping the area clean can help anal fissures heal. Drinking plenty of fluids,
taking stool softeners, eating foods with fiber, and exercising regularly can help
treat and prevent fissures by making bowel movements easier to pass. Keeping the area
clean and applying ointments can relieve pain and speed healing.
Rarely, a fissure doesn't heal. In this case, the doctor may recommend surgery.
