9. Etiology
(kristinaschwerin
et.al.2010)

10. Increased risk of anorexia nervosa among first-degree
biological relatives of individuals with the disorder
Twin studies
concordant rates for monozygotic twins is significantly higher
than those for dizygotic twins.
Genetic Factors May Predispose to Eating
Disorders

11. Genetics Linked to Anorexia
Records from 30,000 Swedish twins found
identical twins more likely to share an eating
problem than fraternal twins or non twin
siblings
found that genes were responsible for 56%
of the cases.
“People need to understand that they are fighting
their biology and not just a psychological need to be
thin”
By Dr. Cynthia Bulik of University of North Carolina
School of Medicine

12. Etiology
(kristinaschwerin
et.al.2010)

13. Personality Traits
Low self-esteem
Feelings of inadequacy or lack of
control in life
Fear of becoming fat
Depressed, anxious, angry, and lonely
feelings
Keep feelings to themselves

14. Etiology
(kristinaschwerin
et.al.2010)

15. Environmental Factors
1-Interpersonal Factors
Troubled family and personal relationships
Difficulty expressing emotions and feelings
History of being bullied based on weight
History of trauma, sexual, physical and/or mental abuse
-60-75% of all bulimia nervosa patients have a history of
physical and/or sexual abuse

16. Environmental Factors: Social
2-Social Factors (media, clutural and Family pressures)
Cultural pressures that glorify "thinness" and place value
on obtaining the "perfect body”
Mothers who are overly concerned about their
daughter’s weight and physical attractiveness might
cause increase risk for development of eating disorders
Girls with eating disorders often have brothers and a
father who are overly critical of their weight.
People pursing professions or activities that emphasize
thinness are more susceptible
ie. Modeling, dancing, gymnastics, wresting

21. Diagnosis AN (DSM-5):
Restriction of energy intake relative to

body weight in the context of age, sex.
Intense fear of gaining weight or becoming

not engaged in recurrent episodes of binge eating or
purging behavior
Binge-Eating/Purging Type: during last 3 months,the
person engaged in
recurrent episodes of binge eating or purging behavior

23. Epidemiology:

Death 3-8%
Age: 10-30years.
Risk : Sp. After stress
M:F ratio 1: 20
In professions modeling –
ballet dancers.

24. Anorexia Nervosa
*onset and course
mean age at onset is 17 years
bi-modal peaks at ages 14 and 18
course and outcome are highly variable
30 % recover after a single episode
30 % fluctuation pattern of weight gain followed by
relapse
30% chronic deteriorating course of the illness over many
years
> 3 years of illness: prognosis is poor

29. Anorexia Nervosa: Treatment
Determine inpatient vs. day treatment vs. outpatient
Multidisciplinary teams are ESSENTIAL!
Family Doctors
Certified Psychiatrist
Certified Nurse
Certified Psychologist
Nutritionist
1
st
: weight restoration : Nutritional Management.
2
nd
: psychological : Distortion of body image, low self-
esteem, and interpersonal conflicts
3
rd
: maintinance:Achieving long-term remission and
rehabilitation.

30. Anorexia Nervosa : Hospitalization
Indication :
 <75% ideal body weight
 Hypothermia T<36
 Bradycardia HR<50 while awake, <45 asleep
 Orthostasis-drop in sbp >10, increase in HR>35
 Dehydration
Severe hypokalemia (<2-3 mmol/L) or other
electrolyte abnormality
Severe depression/suicidality–Psychiatric
admit
Refractory to outpatient treatment

31. Weight Restoration : Nutritional
Manegement
Oral Or Intavenous Feeding
-Intravenous feeding is used for patients who refuse to eat or the
amount of weight loss has become life threatening
Physician strictly sets the rate of weight gain
Usually from half to one kg per week
In the beginning 1,000 calories are given per day
Calorie intake may eventually go up to 3,500 calories per day
Dietitian is often used to develop strategies for planning
meals and to educate the patient and parents
Useful for achieving long-term remission

32. Anorexia Nervosa:
Psychological Therapy
Best evidence is for family-based treatment (Maudsley
approach)
Who: younger patients who live at home, intact family
Philosophy: no-blame, family did not cause anorexia; family
is the best resource to help her get better
Elevate family’s anxiety about the gravity of the illness.
Empower parents to do whatever they need to do to get the
anorexic to eat. Align siblings with the patient for support.
Externalize the anorexia.
“Family Meal”
Once weight-restored: explore the family dynamics and
psychological issues.

33. Anorexia Nervosa: Medications
No approved medication treatments for Anorexia Nervosa
Prozac (or other SSRI) for co-morbid depression or anxiety
Low-dose Atypical Antipsychotics off-label for near-
psychotic thinking that is characteristic of anorexia,
Zyprexa may help with weight gain
-problem: informed consent for risks of weight gain

34. Feeding and Eating Disorders
Anorexia Nervosa
Bulimia Nervosa
Binge Eating Disorder (BED)
Avoidant/Restrictive Food Intake
Disorder (ARFID)
Pica
Rumination Disorder

37. Diagnostic Criteria for Bulemia Nervosa DSM-5
A. Recurrent episodes of binge eating:
(1) Eating large amount in a discrete period of time
(2) lack of control over eating
B. Recurrent compensatory behavior in order to prevent
weight gain.
C. Binge eating and inappropriate compensatory
behaviors is at least once a week for 3 months.

38. Bulemia: Epidemiology
Lifetime Prevalence
1.5% women
0.5% men
Prevalence of binge-purge behaviors:
13% girls
7% boys

39. Medical Complication
Electrolyte abnormalities
Dental –loss of enamel, chipped teeth, cavities
Parotid enlargement
Conjunctival hemorrhages
Calluses on dorsal side of hand (Russel’s sign)
Esophagitis
hematemesis
Latxative-dependent: cathartic colon, melena, rectal
prolapse

42. Bulemia: Treatment
Multidisciplinary team
Family Doctors
Certified Psychiatrist
Certified Nurse
Certified Psychologist
Nutritionist
Treatment Approches :
Evidence based Treatment :
Cognetive Behavior Therapy + Antidepressant
(SSRI)

43. Bulimia Treatment
Primary Goal
Cut down or eliminate binging and purging
Patients establish patterns of regular eating
Treatment Involves:
Psychological support
Focuses on improvement of attitudes related to E.D.
Encourages healthy but not excessive exercise
Deals with mood or anxiety disorders
Nutritional Counseling
Teaches the nutritional value of food
Dietician is used to help in meal planning strategies
Medication management
Antidepressants (SSRI’s) are effective to treat patients who also
have depression, anxiety, or who do not respond to therapy alone
May help prevent relapse

44. Bulemia: Individual Therapies
Interpersonal therapy (IPT) (short-term treatment
focused on life transitions)
Psychodynamic Psychotherapy (good for long-term
results in people with chronic depressive and
personality symptoms)
Family therapy is a good option if patient is young and
still lives at home (But not as much evidence as for
Anorexia)

45. Psychological Treatment
2-Group Therapy
Provides a supportive network
Members have similar issues
Can address many issues, including:
Alternative coping strategies
Exploration of underlying issues
Ways to change behaviors
Long-term goals

46. Bulemia: Medicaions
High-dose Fluoxetine/Prozac (SSRI) –very good
evidence!
Sertraline/Zoloft (SSRI) –some good evidence
Buproprion/Wellbutrin (other antidepressant) –
contraindicated! (risk of seizures if history of
purging)
Topiramate/Topomax (mood stabalizer, promotes
weight loss) –some good evidence, but use with
caution esp if low-weight

47. Nutritional Counseling

48. Bulemia: Prognosis
33% remit every year
But another 33% relapse into full criteria
Adolescent-onset better prognosis than adult-onset
Death-rate = 1%
