How do the anorexia nervosa subtypes differ?

• A. Binge-eating/purging type is defined by extreme restriction of intake without binge episodes.
• B. Binge-eating/purging type has no restriction on intake.
• C. Binge-eating/purging type involves recurrent binge eating followed by purging or other compensatory behaviors; restricting type involves severe restriction of intake without binge/purge patterns.
• D. Restricting type involves binge eating but no purging.

Answer: (C)

Main concept: Anorexia nervosa has two subtypes distinguished by eating behaviors. The binge-eating/purging subtype includes recurrent binge eating episodes or purging behaviors (or both) within a recent period. The restricting subtype involves severe restriction of intake with no recurrent binge eating or purging during that same period. Binge eating means eating a larger amount of food than most people would eat in a similar timeframe and feeling a loss of control; purging covers actions like self-induced vomiting or misuse of laxatives, diuretics, or enemas. This distinction is exactly what option describes, making it the best answer.
