Overview

Rumination disorder is a childhood eating disorder in which the sufferer brings up partially digested food and rechews it before swallowing it or spitting it out.

Rumination disorder typically occurs within the first 3-12 months of age and can lead to the child becoming malnourished.

While Rumination Disorder (originally Childhood Rumination Disorder) may begin in childhood or infancy, adults may also have this chronic disorder, for which there is presently no known cure nor cause. While those diagnosed with this condition in childhood may 'grow out of it', it is by no means a medical fact that they are bound to do so by adolescence or adulthood.

Epidemiology and Demographics

Prevalence

• Prevalence data for rumination disorder are inconclusive
• Higher in certain groups, such as individuals with intellectual disability

Diagnostic Criteria

DSM-V Diagnostic Criteria for Intellectual Disability

“

A. Repeated regurgitation of food over a period of at least 1 month. Regurgitated food may be re-chewed, re-swallowed, or spit out. AND B. The repeated regurgitation is not attributable to an associated gastrointestinal or other medical condition (e.g., gastroesophageal reflux, pyloric stenosis). AND 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. AND D. If the symptoms occur in the context of another mental disorder (e.g., intellectual disability Intellectual developmental disorder or another neuro developmental disorder),they are sufficiently severe to warrant additional clinical attention. Specify if: In remission: After full criteria for rumination disorder were previously met, the criteria have not been met for a sustained period of time.
