The essential feature of Rumination Disorder is the repeated regurgitation and rechewing of food that develops in an infant or child after a period of normal functioning and lasts for at least 1 month. Partially digested food is brought up into the mouth without apparent nausea, retching, disgust, or associated gastrointestinal disorder. The food is then either ejected from the mouth or, more frequently, chewed and reswallowed.
