Anorectal abscesses cannot always be prevented. Early treatment of erosions of the bowel lining can help prevent an anorectal abscess. Stool softeners can be used to improve chronic constipation. Effective treatment of underlying disorders, such as diabetes, can lower the risk of abscess formation.
An anorectal abscess that is untreated or not fully healed can get worse. It can develop into a fistula or a life-threatening infection. A fistula is an abnormal opening or tract that connects two organs that are not supposed to be connected.
An anorectal abscess is not contagious and poses no risk to others.
