Anorexia nervosa, bulimia nervosa, and binge eating disorder share the feature of a disturbed relationship with eating and the body, but they differ significantly in their clinical presentation, their psychological underpinnings, and the specific approach that treatment requires. Anorexia involves severe restriction of food intake driven by an intense fear of weight gain and a distorted perception of body size, and it carries serious medical risks that affect the parameters of psychological treatment. Bulimia involves cycles of binge eating followed by compensatory behaviors, most commonly purging, and is often associated with significant shame, secrecy, and a more ambivalent relationship with the eating behavior than anorexia typically produces. Binge eating disorder involves recurrent episodes of consuming large amounts of food in a compressed timeframe, accompanied by feelings of loss of control and significant distress, without the compensatory behaviors that characterize bulimia.
Dr. Steinbok's clinical assessment at his Boca Raton practice distinguishes between these presentations and addresses the specific psychological dynamics that each involves. Anorexia treatment must account for the ego-syntonic quality of the restriction and the degree to which the disorder has become organized around a patient's identity. Bulimia treatment often involves the shame and secrecy surrounding the binge-purge cycle alongside the underlying emotional regulation difficulties that drive it. Binge eating disorder treatment focuses on the emotional eating function and the psychological states the bingeing is managing. Each requires a different clinical emphasis, and an eating disorder psychologist in Boca Raton who treats them as variations on a single problem tends to produce less effective outcomes than one who engages with the specific features of each presentation.
