What are anal tears?

Anal tears are small cuts or rips in the skin of your anus. Your anus is the opening from which stools (feces) come out. A tear here makes passing stools very painful.

If you have an anal tear (also called anal fissure), the pain after passing stools can last for hours after you've been to the bathroom.

Doctors don't know why some people get anal tears and others don't. There are a number of reasons why you may get an anal tear.

  • Passing hard and dry stools. These types of stools can cause your
     
     
     
     
     
    anus
    The anus, which is at the end of the rectum, is where a stool leaves your body when you go to the bathroom. Part of the anus is a muscle that helps you hold in the stool until you are on the toilet.

    constipated
    When you're constipated, you have difficulty passing stools (feces). Your bowel movements may be dry and hard. You may have fewer bowel movements than usual, and it may be a strain when you try to go.
     
     
     
     
     
    Constipation. When you're constipated, passing stools is difficult and you don't pass them often enough. This may lead to tears in your anus. But we don't know for sure how many people get tears because of constipation.
  •  
     
     
     
     
    diarrhea
    Diarrhea is when you have loose, watery stools and you need to go to the bathroom far more often than usual. Doctors say you have diarrhea if you need to go to the bathroom more than three times a day.
     
     
     
     
     
    Diarrhea may also cause tears in some people.
Most anal tears happen at the back of the anus. But 1 in 4 women and 1 in 12 men get a tear at the front.

It's unusual to have more than one tear at a time, or for the skin on the sides of the anus to tear. If this happens, your doctor may do some tests to see if the tears are due to an
 
 
 
 
 
infection
You get an infection when viruses, bacteria, fungi or other tiny organisms get into your body. These bugs are so tiny that you can't see them without a microscope. For example, an infection in your airways causes the common cold. And an infection in your skin can cause rashes such as athlete's foot.
 
 
 
 
 
infection or a problem with your digestion.

Anal tears often heal on their own. Or you may need to take some simple steps to help them heal. To learn more, see What can I do to help my anal tear heal?

Sometimes a tear stays open for several weeks or more. Tears that don't heal, or come and go for months, are called chronic anal tears.

Doctors think that some tears don't heal because the muscle that controls the anus tightens up (goes into spasm). The tightness can cause more pain, and it stops blood from getting to your anus properly. This prevents the tear from healing.
