<unk>  is thought to be very common, but much under-reported due to embarrassment. One study reported a prevalence of 2.2% in the general population. It affects people of all ages, but is more common in older adults (but it should not be considered a normal part of aging).<unk> es are more likely to develop it than males (63% of those with<unk>  over 30 may be<unk> e). In 2014, the National Center for Health Statistics reported that one out of every six seniors in the U.S. who lived in their own home or apartment had<unk> . Men and women were equally affected. 45–50% of people with<unk>  have severe physical and/or mental disabilities. Risk factors include age,<unk> e gender, urinary incontinence, history of vaginal delivery (non-Caesarean section childbirth), obesity, prior anorectal surgery, poor general health and physical limitations. Combined urinary and<unk>  is sometimes termed double incontinence, and it is more likely to be present in those with urinary incontinence. Traditionally,<unk>  was thought to be an insignificant complication of surgery, but it is now known that a variety of different procedures are associated with this possible complication, and sometimes at high levels. Examples are midline internal sphincterotomy (8% risk), lateral internal sphincterotomy,<unk> stulectomy,<unk> stulotomy (18-52%), hemorrhoidectomy (33%), ileo-anal reservoir reconstruction, lower anterior resection, total abdominal colectomy, ureterosigmoidostomy, and anal dilation (Lord's procedure, 0-50%). Some authors consider obstetric trauma to be the most common cause.
