EATING DISORDERS - PROGRESS AND PROBLEMS

Recent research on Anorexia Nervosa and Bulimia Nervosa has yielded an increasingly detailed understanding of the range of biological and ps ychological abnormalities associated with these eating disorders. Inhe rited vulnerabilities, cultural pressures, and adverse individual and family experiences all appear to contribute to the onset of extreme di eting, binge eating, and purging. Once initiated, these behaviors give rise to multiple physiological disturbances, some of which may serve to perpetuate the illness.

This article reviews current thinking on the etiology and treatment of the two major eating disorders and a related syndrome, Binge Eating D isorder.
