Answer to Question 1
Anorexia Nervosa
A person with anorexia nervosa demonstrates the following:
1 . Refusal to maintain body weight at or above a minimal normal weight for age and height
2 . Intense fear of weight gain or becoming fat, even though underweight
3 . Distorted body image, undue influence of body weight or shape on self-evaluation, or denial of the seriousness of the current low body weight
Two types:
Restricting type: During the episode of anorexia nervosa, the person does not regularly engage in binge eating or purging behavior (that is, self-induced vomiting or the misuse of laxatives, diuretics, or enemas).
Binge-eating/purging type: During the episode of anorexia nervosa, the person regularly engages in binge eating or purging behavior (that is, self-induced vomiting or the misuse of laxatives, diuretics, or enemas).
Bulimia Nervosa
A person with bulimia nervosa demonstrates the following:
1 . Recurrent episodes of binge eating characterized by:
a . Eating in a discrete period of time an amount of food that is definitely larger than most people would eat during a similar period of time and under similar circumstances
b. A sense of lack of control over eating during the episode
2 . Recurrent compensatory behavior to prevent weight gain, such as self-induced vomiting; misuse of laxatives, diuretics, enemas, or other medications; fasting; or excessive exercise
3 . Binge eating and compensatory behaviors that occur, on an average, at least twice a week for three months
4 . Self-evaluation unduly influenced by body shape and weight
5 . Does not occur exclusively during episodes of anorexia nervosa.
Two types:
Purging type: The person regularly engages in self-induced vomiting or the misuse of laxatives, diuretics, or enemas.
