Rumination Disorder
Diagnostic Criteria
Criterion A
Repeated regurgitation of food over a period of at least 1
month. Regurgitated food may be re-chewed, re-swallowed, or spit out.
Criterion B
The repeated regurgitation is not attributable to an associated gastrointestinal or other medical condition (e.g., gastroesophageal reflux, pyloric stenosis).
Criterion C
The eating disturbance does not occur exclusively during the course of anorexia nervosa, bulimia nervosa, binge-eating disorder, or avoidant/restrictive food intake disorder.
Criterion D
If the symptoms occur in the context of another mental disorder (e.g., intellectual developmental disorder or another neurodevelopmental disorder), they are sufficiently severe to warrant additional clinical attention.
Specifier
In remission: After full criteria for rumination disorder were previously met, the criteria have not been met for a sustained period of time.
