Faecal incontinence implies loss of voluntary control of passage of faeces from the anus. Faecal soiling of the clothes occurs, which is socially embarrassing for the patient. Any disease process that interferes with rectal sensation or affects function of the anorectal musculature may produce incontinence. However, incontinence may still occur with normal sphincters and pelvic floor, for example in severe diarrhoea.
