What cauaes anal leakage?

Anal leakage: Processes that interrupt the integrity of the sphincter muscle or the hemorrhoid columns can produce anal leakage. For example, stretching of the sphincter muscle, a flareup of hemorrhoids, mucosal prolapse, or an abnormal connection called a fistula can all produce what would be termed anal leakage. I suggest you see a surgeon for a anorectal examination.
