, a) Provide and differentiate the diagnostic criteria and hallmark features of
Anorexia Nervosa, Bulimia Nervosa and Binge-eating disorder (20)
To differentiate the diagnostic criteria and hallmark features of Anorexia Nervosa, Bulimia
Nervosa, and Binge-Eating Disorder, we will look at the definitions, key characteristics, and
specific criteria for each disorder as outlined by the Diagnostic and Statistical Manual of Mental
Disorders, Fifth Edition (DSM-5).
Anorexia Nervosa (AN)
Definition: Anorexia Nervosa is characterized by an intense fear of gaining weight and a
distorted body image that leads to self-imposed starvation and excessive weight loss.
Diagnostic Criteria:
1. Restriction of energy intake: Leading to a significantly low body weight in the context
of age, sex, developmental trajectory, and physical health.
2. Intense fear of gaining weight: Or becoming fat, even though underweight.
3. Disturbance in self-perceived weight or shape: Undue influence of body weight or
shape on self-evaluation, or persistent lack of recognition of the seriousness of the current
low body weight.
Hallmark Features:
• Significant weight loss and malnutrition.
• Amenorrhea (absence of menstruation) in females.
• Preoccupation with food, dieting, and body size.
• Use of extreme measures to lose weight, such as excessive exercise, purging, or use of
diet pills.
Bulimia Nervosa (BN)
Definition: Bulimia Nervosa involves recurrent episodes of binge eating followed by
inappropriate compensatory behaviors to prevent weight gain, such as self-induced vomiting,
misuse of laxatives, or excessive exercise.
Diagnostic Criteria:
1. Recurrent episodes of binge eating: Characterized by both:
o Eating, in a discrete period (e.g., within any 2-hour period), an amount of food
that is definitely larger than what most individuals would eat in a similar period
under similar circumstances.
o A sense of lack of control over eating during the episode.
