Rumination in adults: two case histories.

Rumination has been reported to be a relatively rare disorder of eating during infancy. Over the past decade, there appears to be a renewed interest in and recognition of adult rumination. Although some authors believe adult rumination is benign, others have begun to link it with both eating disorders and depressive symptoms. This paper presents two adult cases whose rumination was associated with anorexia and bulimia nervosa. More identification and study of adult rumination is needed to clarify its course and medical significance.
