Common condition affecting up to 10% of the population, particularly older institutionalised people.
The pathogenesis is often multifactorial with local, anatomical, or systemic disorders potentially contributing.

Faecal incontinence is the involuntary passage of flatus or faeces. The underlying aetiology is often complex with multiple possible contributing factors including anorectal structural abnormalities, neurological disorders, cognitive or behavioural dysfunction, stool consistency, or general disability (particularly age). Sometimes no cause can be found. It is extremely common, affecting up to 10% of adults, but the true prevalence remains hidden due to the associated stigma.
