Eating disorders such as anorexia nervosa (AN), and bulimia nervosa (BN) are characterized by serious disturbances in eating behaviors as well as intense preoccupation with issues regarding eating, weight, body size and shape. Eating concerns and disordered eating behavior fall on a spectrum. While someone may not meet the very specific criteria outlined by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) for anorexia nervosa and bulimia nervosa, these individuals may fit into a category called Eating Disorder Not Otherwise Specified (EDNOS) which includes those individuals who struggle from binge eating disorder.
