If a parent often finds empty food wrapper's in their teenage daughter's bedroom, if she spends several minutes in the bathroom right after every meal, and if she exercises for more than an hour every day, the parent may suspect
a. bulimia nervosa.
b. anorexia nervosa.
c. binge-eating disorder.
d. chronic dieting syndrome.
A
Bulimia nervosa is characterized by episodes of binge eating (food wrappers may be evidence of this), and compensatory behaviors including purging (time spent in the bathroom after meals may signal vomiting), and excessive exercise. Anorexia nervosa is characterized by refusal to maintain weight above a certain low value and fear of gaining weight; this would be demonstrated by restricted food intake and/or excessive exercise. Binge-eating disorder is characterized by episodes of binge eating (the food wrappers may suggest this), but without compensatory be-haviors. Chronic dieting may be associated with several eating disorders, but is not a defined syndrome.
