Repeated passage of feces into inappropriate places (e.g., clothing, floor), whether involuntary or intentional, occurring at least once monthly for at least 3 months, in a child with a chronological or developmental age of at least 4 years, not attributable solely to a substance or a general medical condition other than through a mechanism involving constipation.
Encopresis is repeated, clinically significant passage of stool into inappropriate places in a child old enough (at least 4 years chronological or developmental age) that this would no longer be expected. Most cases are associated with constipation and overflow incontinence, where impacted stool leads to involuntary leakage — a mechanism distinct from encopresis without constipation, which is less common and may involve a more intentional pattern.
Requires a chronological or developmental age of at least 4 years; the 'with constipation and overflow incontinence' presentation is the more common of the two specifiers and often begins with painful or difficult bowel movements that lead to stool withholding, chronic constipation, and eventual involuntary overflow leakage.
Can cause significant shame, social withdrawal, and family conflict, particularly since soiling is often met with frustration or punishment before the underlying constipation-driven mechanism is recognized; can significantly affect school attendance and peer relationships if not addressed.
A history of painful, hard, or infrequent bowel movements often precedes the onset of the constipation-with-overflow presentation; stool withholding behaviors (avoiding the toilet, crossing legs, hiding) are commonly observed as the pattern develops.
Toilet-training practices, expectations for independence in toileting, and family comfort discussing bowel habits vary across cultures; clinicians should approach the topic sensitively and avoid assuming psychological or behavioral intent before a medical evaluation for constipation has been completed.
A common misconception is that encopresis reflects willful defiance or laziness. The majority of cases are driven by an underlying constipation-and-overflow mechanism that is physiological in nature, even though the resulting soiling can look, superficially, like a behavioral or intentional act.
If chronic constipation is found to stem from a specific, independently significant medical condition (e.g., Hirschsprung disease) requiring its own primary medical management, ensure that condition is addressed directly alongside the behavioral diagnosis rather than treating the soiling as purely psychological.
An 8-year-old has recurrent episodes of soiling underwear, on medical evaluation found to have a large volume of retained, impacted stool and a history of painful bowel movements leading to toilet avoidance — consistent with Encopresis, with constipation and overflow incontinence.
Know
Encopresis is repeated, clinically significant passage of feces into inappropriate places in a child at least 4 years old, most often driven by an underlying constipation-and-overflow mechanism rather than willful defiance.
Notice
In a case, notice whether there's a history of painful or withheld bowel movements and medical evidence of constipation (pointing to the more common 'with constipation' specifier) versus a pattern without such a history.
Distinguish
Distinguish from a purely medical/gastrointestinal condition by confirming whether constipation is the driving mechanism (still consistent with the diagnosis) or an independently significant medical condition needing its own primary treatment; note the natural pairing with Enuresis as the two elimination disorders, which can co-occur.
Recognize
Repeated passage of feces into inappropriate places (e.g., clothing, floor), whether involuntary or intentional; at least one such event a month for at least 3 months; chronological age at least 4 years (or equivalent developmental level); behavior not attributable exclusively to the direct physiological effects of a substance (e.g., a laxative) or a general medical condition, except through a mechanism involving constipation. Specifiers: with constipation and overflow incontinence, or without constipation and overflow incontinence.
Distinguish
Distinguish from a purely medical/gastrointestinal condition by confirming whether constipation is the driving mechanism (still consistent with the diagnosis) or an independently significant medical condition needing its own primary treatment; note the natural pairing with Enuresis as the two elimination disorders, which can co-occur.
A general medical condition causing chronic constipation independent of behavioral factors (e.g., Hirschsprung disease, hypothyroidism, anatomical abnormality) should be considered and, when present as the primary driver, evaluated medically alongside or instead of the behavioral diagnosis — though encopresis via a constipation-overflow mechanism remains diagnosable even when constipation itself has straightforward physiological origins, since the criterion excludes only conditions unrelated to the constipation mechanism.
Learners often overlook that a child with Autism Spectrum Disorder who resists or avoids the toilet is not automatically diagnosed with Encopresis — the mechanism (sensory/behavioral avoidance and rigidity vs. a constipation-driven retentive pattern) is what actually distinguishes the two, not just the presence of soiling.
Learners often assume any soiling in a child past toilet-training age is automatically Encopresis. In fact, sub-threshold frequency or duration, or presentations of unclear or mixed elimination pathway, route to the residual category rather than Encopresis itself.
Both are sometimes attributed to willful defiance or laziness by frustrated caregivers, when most presentations -- particularly nocturnal enuresis and constipation-driven encopresis -- are involuntary and physiologically or genetically rooted rather than behavioral choices.
