There are two major types of AN; and one minor type
In the restricting type, patients do not regularly engage in binge eating or purging. In the binge-purge type, AN is combined with binge eating or purging behavior, or both.
Atypical: AN, except the patient is not underweight despite significant weight loss
Assessing the patient’s __________ is essential to determining the diagnosis of AN
Body Image
___________________________________________ is an obvious red flag for the presence of an ED. Additionally, AN should be considered in any girl with ___________who has _____________________.
Weight loss from a baseline of normal body weight
secondary amenorrhea … lost weight
A(n) _________ weight _____________(timing) is the most accurate way to assess weight.
gown-only … after urination
In AN, A combination of malnutrition and stress causes ____________. (Define)
Hypothalamic hypogonadism: the hypothalamic-pituitary-gonadal axis shuts down as the body struggles to survive, directing finite energy resources to vital functions.
_____ will continue to be an important clinical sign that an adolescent female’s body is malnourished. It occurs for two reasons:
Amenorrhea
- Hypothalamic hypogonadism –> hypothalamic amennorhea
- Lack of adipose interrupts activation of estrogen
An adolescent female needs about __% body fat to restart menses and __% body fat to initiate menses if she has primary amenorrhea
17 … 22
A(n) _________ should be performed in those suspected to have AN, because significant abnormalities may be present, most importantly _________.
electrocardiogram (ECG) … prolonged QTc syndrome
Manualized family therapy
10 weeks are devoted to empowering parents
11–16, returns control over eating to the adolescent once he or she accepts the demands of the parents
17–20, maintaining a healthy weight; shifts the focus away from the ED to establishing a healthy adolescent identity
Practitioners frequently use _____________ for treatment of AN, despite the lack of evidence supporting efficacy.
atypical antipsychotics (risperidone, quetiapine, and esp. olanzapine)
____ repeatedly have been shown to not be helpful in the initial therapy of AN. A recent study showed that their use may decrease _________ when used in malnourished patients. However, …
SSRIs … bone mineral density
… SSRIs (fluoxetine, citalopram, or sertraline) may help prevent relapse.

- A sense of lack of control during the episode (eg, feeling that one cannot stop eating or control what or how much one is eating).
Characteristic of Bulimia Nervosa and Binge Eating Disorder (BED)
Binge eating followed by [recurrent inappropriate compensatory behavior to prevent weight gain (eg, self-induced vomiting; misuse of laxatives, diuretics, or other products; excessive exercise; fasting).]
Characteristic of Bulimia Nervosa [Purging disorder]
Binge eating (and inappropriate compensatory behaviors) occur(s) at least once a week for 3 months (on average).
