Extra notes:
1. Bulimia
Nervosa
A. Recurrent episodes of binge eating. An episode of
binge eating is characterized by both of the following:
• Eating, in a discrete period of time (e.g., within
any 2‐ hour period), an amount of food that is
definitely larger than most people would eat
during a similar period of time and under
similar circumstances.
• A sense of lack of control over eating during
the episode (e.g., a feeling that one cannot stop
eating or control what or how much one is
eating).
B. Recurrent inappropriate compensatory behaviors in
order to prevent weight gain, such as
• self‐induced vomiting;
• misuse of laxatives,
• diuretics or other medications;
• fasting; or
• excessive exercise.
C. The binge eating and inappropriate compensatory
behaviors both occur, on average, at least once a
week for 3 months.
D. Self‐evaluation is unduly influened y ody shape
and weight.
• Evaluating self despite body shape and weight
• Believe they are larger than what it might
actually be

2.
Anorexia
Nervosa
A. Restriction of energy intake relative to requirements,
leading to a significantly low body weight in the
context of age, sex, developmental trajectory, and
physical health. Significantly low weight is defined as
a weight that is less than minimally normal or, for
children and adolescents, less than that minimally
expected.
• Way below the low end of the spectrum thin
B. Intense fear of gaining weight or of becoming fat, or
persistent behavior that interferes with weight gain,
even though at a significantly low weight.
C. Disturbance in the way in which one’s body weight
or shape is experienced, undue influence of body
weight or shape on self‐ evaluation, or persistent lack
of recognition of the seriousness of the current low
body weight.
• Look in miror = completely out of touch of
reality
• Think fat when skinny
Specify whether: 2 types
(1) Restricting type:
• During the last 3 months, the individual has
not engaged in recurrent episodes of binge
eating or purging behavior
• (i.e., self‐induced vomiting or the misuse of
laxatives, diuretics, or enemas).
• This subtype describes presentations in which
weight loss is accomplished primarily through
dieting, fasting, and/or excessive exercise.
• restricting calories = main difference
(2) Binge‐eating/purging type:
• During the last 3 months, the individual has
engaged in recurrent episodes of binge eating
or purging behaviour
• (i.e., self‐induced vomiting or the misuse of
laxatives, diuretics, or enemas).
