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.
