Rumination Disorder

Overview

Description

Rumination Disorder is characterized by repeated regurgitation of food, which may be re-chewed, re-swallowed, or spit out. This behavior occurs for at least one month, is not attributable to a gastrointestinal or other medical condition, and is not exclusively during the course of another eating disorder. It can occur in infancy, childhood, adolescence, or adulthood.

Prevalence

Exact prevalence is unknown; more common in infants and individuals with developmental disabilities, but can occur across the lifespan.

Age of Onset

In infants, typically between 3–12 months; in older individuals, may emerge in adolescence or adulthood in the context of stress, anxiety, or habit formation.
