due to her weight loss
You begin to discuss healthy ways of gaining
weight, she storms out of the room and says
“No Way I’m doing that – I’m fine the way I
am”

Type



Prevalence – Estimated at 1%
90-95% are female
Bimodal peaks of onset at ages 13-14 and 1718
Prepubertal may be associated with more
severe profile
Adolescent onset associated with better
prognosis that prepubertal and adult onset
30% of patients were obese

Determine Level of Care:
 Medically Unstable: medical hospital
▪ Heart rate <40, glucose < 60 mg/dl, potassium <3 mEq/l,
orthostatic hypotension
 Psych Unstable: psych hospital
 Med/Psych stable:
▪ <70% IBW: Inpatient
▪ 70-85% IBW: Partial/Day treatment
▪ >85%: Outpatient

Create treatment team
 Therapist: individual and family
 Nutritionist
 Medical provider
 Psychiatrist


Coordination between all providers is KEY
Start with therapeutic alliance



School – Consider reduced schedule
Exercise: limit activities, team sports, gym
Amennorhea: consider OCP >6-12 months
 Calcium 1200-1500 mg
 Vitamin D 400-800 IU
 Dexa Scan if no menses > 6 months


Standardized tables
Premorbid weight
Weight at which patient had last period
Progressive weight goals
Weight at which patient feels safe and
healthy
May need to postpone discussion



Close monitoring: every 1-2 weeks
Standardized weights: gown, empty bladder
Weight gain: ½-1 lb per week
 If faster risk refeeding syndrome



Ask patient if they want to know weight
Avoid comments about weight
During treatment constantly assess:
 Resistance, denial, non-compliance, deception
 Depression, anxiety
 Purging activities

Treat psychiatric co-morbities





Cardiac: Arrhythmias, prolonged QT, heart
failure, pericardial effusions
Neurologic: cerebral atrophy
Endocrine:Osteoporosis
Renal: renal failure, nephrolithiasis
GI: gastric dysmotility
Dental: enamel erosions


Initial visit – after coaxing back into room,
you explain your concerns about health
She reluctantly agrees to see a nutritionist,
refuses to see a therapist
Follow-up one week later, weight is down 2
pounds – refused to implement changes
suggested by nutritionist
Admitted to day treatment program

< 50% achieve full recovery
 Predictors of recovery: higher body weight at intake,
shorter duration of intake episode, and atypical features



1/3 improve with lingering symptoms
1/5 remain chronically ill
Mortality
 Mortality rate is 12x higher than that for age matched
women
 24% of deaths due to suicide


K.P. presents to your office 5 years since
initial diagnosis of anorexia nervosa – since
that time, she has had one inpatient
admission and 3 partial hospitalizations – last

2 years

and scars on her knuckles

Medications
 SSRIs – most studied is fluoxetine 60 mgs/day


Related to purging activity
Dental: erosion, false teeth
GI: esophageal tears, cathartic colon, GERD
Metabolic: electrolye imbalance, dehydration
