Rumination disorder is repeated regurgitation (backflow of food from the stomach into the mouth) and re-chewing of food. Symptoms must go on for at least 1 month to fit the definition of rumination disorder. There does not appear to be upset, retching, or disgust associated with the regurgitation, and it may appear to cause pleasure.

Rumination disorder usually starts after 3 months of age, following an period of normal digestion. It occurs in infants and is rare in children and teenagers. The cause is often unknown. Certain problems such as lack of stimulation of the infant, neglect, and high-stress family situations, have been associated with the disorder.
