Prevalence of Bowel Incontinence

Unless asked specifically about it, individuals often are reluctant to disclose incontinence – even when talking to their own physician. This reluctance can make it difficult to obtain accurate estimates of the true prevalence of fecal incontinence. The results, and criteria, from several studies vary in reported prevalence of fecal incontinence.

"I thought I was the only one."

"You feel so alone. You don't dare tell most people."

Fecal incontinence affects people of all ages.

• In women living in the community, fecal incontinence occurs in 6% of those younger than 40 and increases to 15% in older women. Combined fecal and urinary incontinence is estimated to occur in about 10% of women.[1] 
• In men living in the community, fecal incontinence occurs in 6–10% and increases slightly with age. Combined fecal and urinary incontinence occur in 10% of men.[1]
• Two nursing home studies have identified a 45.0%[3] to 47.0%[4] prevalence of fecal incontinence among residents. Studies suggest that incontinence contributes to the decision to institutionalize elderly patients.
• Minor fecal incontinence (staining underclothes or losing less than 2 tsp. of stool) affects 7.4% of adult males and 6.9% of adult females.[2]
• Approximately 30% of people with irritable bowel syndrome (IBS) have frequent loose stools and 20%[5] report fecal incontinence.
• Obstetrical trauma, leading to sphincter muscle injury or pudendal nerve injury, is a common cause of fecal incontinence.[6]
