Rumination disorder is a condition in which a person keeps bringing up food from the stomach into the mouth (regurgitation) and rechewing the food.
Rumination disorder most often starts after age 3 months, following a 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 linked with the disorder.
Rumination disorder may also occur in adults.
- Repeatedly bringing up (regurgitating) food
- Repeatedly rechewing food
Symptoms must go on for at least 1 month to fit the definition of rumination disorder.
People do not appear to be upset, retching, or disgusted when they bring up food. It may appear to cause pleasure.

Rumination disorder is treated with behavioral techniques. One treatment associates bad consequences with rumination and good consequences with more appropriate behavior (mild aversive training).
Other techniques include improving the environment (if there is abuse or neglect) and counseling the parents.
In some cases, rumination disorder will disappear on its own, and the child will go back to eating normally without treatment. In other cases, treatment is needed.
Complications may include:
- Failure to thrive
- Lowered resistance to disease
