rumination disorder
Repeated regurgitation and re-chewing of food occurring for at least one month following normal digestion.
Full Definition
Rumination disorder involves repeated regurgitation of food over a period of at least one month, where previously swallowed food is brought back up into the mouth without apparent nausea, involuntary retching, or associated gastrointestinal illness. The regurgitated food may be re-chewed, re-swallowed, or spit out. In infants, the disorder typically manifests between 3-12 months of age and may be associated with lack of stimulation or neglect. In older children and adolescents, it may be associated with intellectual disability or other mental disorders. The condition can lead to malnutrition, weight loss, and dental problems if untreated.
