FI is a signor a symptom, not a diagnosis. Incontinence can result from different causes and might occur with either constipation or diarrhea. Continence is maintained by several inter-related factors, and usually there is more than one deficiency of these mechanisms for incontinence to develop. The most common causes are thought to be immediate or delayed damage from childbirth, complications from prior anorectic surgery (especially involving the anal sphincters or hemorrhoid vascular cushions) and altered bowel habits (e.g. caused by irritable bowel syndrome, Crohn's disease, ulcerative colitis, food intolerance, or constipation with overflow incontinence). An estimated 2.2% of community dwelling adults are affected.
