Etiology of Eating Disorders
- Biological
- Psychological
- Social
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
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
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

Different Lines of Treatment
29. Anorexia Nervosa: Treatment
Determine inpatient vs. day treatment vs. outpatient
Multidisciplinary teams are ESSENTIAL!
Family Doctors
Certified Psychiatrist
Certified Nurse
Certified Psychologist
Nutritionist
1st: weight restoration : Nutritional Management.
2nd: psychological : Distortion of body image, low self-
esteem, and interpersonal conflicts
3rd: 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
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.
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
48. Bulemia: Prognosis
33% remit every year
But another 33% relapse into full criteria
Adolescent-onset better prognosis than adult-onset
Death-rate = 1%
50. DSM-5 Diagnostic Criteria for Binge Eating
Disorder
Eating, in a discrete period of time , large amount
Lack of control over eating during the episode
Binge eating occurs, on average, at least once a week
for three month
51. Binge Eating Disorders

the regular use of compensatory measures to
counter the binge eating.

-Indications that the binge eating is out of control,
such as eating when not hungry,

-Eating alone because of shame about the
behavior
-Feelings of strong shame or guilt regarding the
binge eating
52. DSM-5 Diagnostic Criteria for Binge Eating
Disorder
BE are associated WITH :
1. Eating much more rapidly than normal
2. Eating until feeling uncomfortably full
3. Eating large amounts of food when not feeling
hungry
4. feeling disgusted with oneself, depressed, or very
guilty afterwards
55. Night eating syndrome (NES) : Diagnosis
Evening hyperphagia (consumption of 25% or more of the total daily
calories after the evening meal) and/or nocturnal awakening and
ingestion of food two or more times per week.
Three of five associated symptoms
- lack of appetite in the morning, urges to eat in the
evening/at night, belief that one must eat in order
to fall back to sleep at night, and/or difficulty
sleeping
56. Night Eating Syndrome : Statistics
Prevalence : in 1 and 2% of the general population, and
approximately 10% of obese individuals.
Sex Ratio : NES affects both men and women
Age of onset : in early adulthood (spanning from late
teenage years to late twenties) and is often long-
lasting, children rarely reporting NES.
57. Complication Of BED
Obesity
-Increase Risk of Type II DM
-- Cardiovascular Disease
-- Breathing problem
-- Physical aliments (joint/
muscle)
Without obesity
-Sleep Problem .
-- Anxiety / Depression .
-- Irritable bowel Syndrome.
-- Early Menstruation.
58. Binge Eating Disorder:
Treatment (Medication)
SSRI
high dose reduces binge behavior short-term
but doesn’t help weight loss
Topomax, Zonisamide (anticonvulsants, mild
mood stabalizer)
Helps binge reduction
Helps weight loss
Caution for adverse effects, high discontinuation rates
59. Binge Eating Disorder:
Treatment (Therapy)
Therapies either prioritize…
Weight loss
Binge-reduction
Neither (ie. relationships, depression etc)
Group psychotherapy
Family need help with co-dependency
12-step Self help groups
Food Addicts in Recovery Anonymous
62. Pica

one month Regurgitated food may be re-chewed, re-
swallowed, or spit out.
Not preceeded by nausea or vomoting

condition (e.g. gastrointestinal condition).
The behaviour does not occur exclusively in the course
of Anorexia Nervosa, Bulimia Nervosa, BED, or
Avoidant/Restrictive Food Intake disorder.
