Fecal incontinence has a significant social and economic impact and significantly impairs quality of life [1-5]. Fecal incontinence can contribute to the loss of the ability to live independently. [5,6]. This topic will review the etiology and evaluation of fecal incontinence in adults. Our recommendations are largely consistent with guidelines issued by the American College of Gastroenterology . The management of fecal incontinence in adults is discussed in detail, separately. (See "Fecal incontinence in adults: Management".)
TERMINOLOGY AND CLASSIFICATION
●Fecal incontinence is defined as the involuntary loss of solid or liquid feces.
●Anal incontinence is defined as the involuntary loss of solid or liquid feces or flatus.
Based on the mechanism of incontinence, fecal incontinence is divided into the following:
●Urge incontinence is characterized by the desire to defecate, but incontinence occurs despite efforts to retain stool.
