rumination (rumination disorders) Repeated regurgitation of food over a period of at
least 1 month. Regurgitated food may be re-chewed, re-s wallowed, or spit out. In
rumination disorders, there is no evidence that an associated gastrointestinal or an-
other medical condition (e.g., gastroesophage al reflux) is sufficient  to account for the
repeated regurgitation.
