Thank you for your query,
Encopresis is an elimination disorder
In most children with encopresis the underlying primary abnormality may be chronic constipation
with fecal impaction
and fecal retention
Many children with encopresis present with abnormal anal sphincter function documented by rectal sphincter physiologic studies like electormyography and defecating a rectal balloon.
The treatment of this condition is clearance of impacted fecal material, short term use of laxatives and adding high dietary fiber to diet to prevent further constipation and behavior management.
This problem comes under mental illnesses, and consult your Pediatrician
to know whether it comes under disability according to your country health policy.
Hope i have answered your query.
