Question

what is the primary difference between anorexia nervosa and bulimia nervosa?
○ anorexia causes physical pain, whereas bulimia does not.
○ anorexia is a chronic condition, whereas bulimia is often short term.
○ anorexia typically develops in childhood or adolescence, whereas bulimia often develops in adulthood.
○ people with anorexia are usually underweight, whereas people with bulimia are often at normal weight.

Explanation:

To determine the primary difference between anorexia nervosa and bulimia nervosa, we analyze each option:

• The first option is incorrect as both disorders can cause physical pain.
• The second option is wrong because both can be chronic; bulimia isn't typically short - term.
• The third option is incorrect as both often develop in adolescence (anorexia) or young adulthood (bulimia), with anorexia not being limited to childhood.
• The fourth option is correct: Anorexia nervosa is characterized by extreme restriction of food intake, leading to being underweight. Bulimia nervosa involves binge - eating and purging, and those with bulimia are often at a normal weight (or may be overweight in some cases).

Answer:

D. People with anorexia are usually underweight, whereas people with bulimia are often at normal weight.
