An anal fissure is a small cut or tear in the lining of the anus. The crack in the skin causes severe pain and some bright red bleeding during and after bowel movements. 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. Or your doctor may need to look for other underlying disorders that can cause anal fissures.
What is anal fissure and what causes it?
Anal fissure - Diagnosis and treatment - Mayo Clinic
An anal fissure is a small tear in the thin, moist tissue 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. You also may experience spasms in the ring of muscle at the end of your anus anal sphincter. Anal fissures are very common in young infants but can affect people of any age. Most anal fissures get better with simple treatments, such as increased fiber intake or sitz baths.
Your doctor will likely ask about your medical history and perform a physical exam, including a gentle inspection of the anal region. Often the tear is visible. Usually this exam is all that's needed to diagnose an anal fissure. An acute anal fissure looks like a fresh tear, somewhat like a paper cut. A chronic anal fissure likely has a deeper tear, and may have internal or external fleshy growths.
An anal fissure fissure-in-ano is a small, oval shaped tear in skin that lines the opening of the anus. Fissures typically cause severe pain and bleeding with bowel movements. Fissures are quite common in the general population, but are often confused with other causes of pain and bleeding, such as hemorrhoids. Anal fissures can occur at any age and have equal gender distribution. A small number of patients may actually have fissures in both the front and the back locations.
