Discussion

Ä Anorexia nervosa and bulimia nervosa are characterized by severe disturbances of eating behavior. The salient feature of anorexia nervosa is a refusal to maintain a minimally normal body weight. Bulimia nervosa is characterized by recurrent episodes of binge eating followed by abnormal compensatory behaviors, such as self-induced vomiting. Anorexia nervosa and bulimia nervosa are closely related. Both occur primarily among previously healthy young women who become overly concerned with body shape and weight.

Explanation

Amenorrhea, self perception of being “fat” and Underweight are features of anorexia nervosa where as binge eating is the feature of Bulimia Nervosa

Comments

Ä Many patients with bulimia nervosa have past histories of anorexia nervosa, and many patients with anorexia nervosa engage in binge eating and purging behavior. In the current diagnostic system, the critical distinction between anorexia nervosa and bulimia nervosa depends on body weight: patients with anorexia nervosa are, by definition, significantly underweight, whereas the weights of patients with bulimia nervosa are in the normal range or above.

Tips

Ä Anorexia nervosa and bulimia nervosa are more prevalent in cultures where food is plentiful and in which being thin is associated with attractiveness. These disorders are more frequent among young women who place a premium on thinness, such as ballet dancers and models. The incidence of anorexia nervosa appears to have increased in recent decades
