Common Eating Problems in Children
 
Food refusal
Inappropriate food for age
Poor appetite
Picky eaters
Faulty feeding practices
 
These can be easily treated with
parents’ education, few feeding
modifications.
 
 
But “
Eating Disorders” 
on the other
hand are much more difficult to treat.
 
 
 
EATING  DISORDERs
 
 
Eating disorders (EDs) are complex
biopsychosocial disorders characterized by
dysfunctional patterns of cognition and
weight control behaviors that result in
significant physical, psychological and
social complications.
 
Affects older children and adolescents.
Incidence is increasing in India over the last
two decades.
 
 
“ED” 
“FED”
 
“Eating Disorders (ED)” – this term has been replaced with
“Feeding and Eating Disorders (FED)” 
in the 5th revision of
the American Psychiatric Association’s 
Diagnostic and
Statistical Manual of Mental Disorders (DSM-5) 
published in
2013 and in the 11th revision of the World Health
Organisation’s International Statistical Classification of
Diseases (ICD-11) and Related Health Problems published in
2019.

edn) (DSM-5). Washington, DC: American Psychiatric Association; 2013.
World Health Organization. International Statistical Classification of Diseases and Related
Health Problems, 11th Revision(ICD-11). Geneva: World Health Organization; 2019.
 
CLASSIFICATION
 
In DSM-5, FED comprises of eight diagnoses –
 
Six specific diagnoses :
1.
Anorexia Nervosa (AN)
2.
Bulimia Nervosa (BN)
3.
Binge Eating Disorder (BED)
4.
Avoidant/Restrictive Food Intake Disorder (ARFID)
5.
Pica and
6.
Rumination Disorder (RD)
 
Two umbrella diagnoses :
1.
Other Specified Feeding or Eating Disorder (OSFED) and
2.
Unspecified Feeding or Eating Disorder (UFED)
 
ANOREXIA  NERVOSA
 
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 minimally
expected.
 
Intense fear of gaining weight or of
becoming fat, or persistent behaviour
that interferes with weight gain, even
though at a significantly low weight.
 
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.
 
 
Two types –
Restricting type
: 
During the last three months, the individual has not engaged in
recurrent episodes of binge eating or purging behaviour (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.
Binge-eating/purging type
: 
During the last three 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).
 
Severity:
Mild: BMI more than 17
Moderate: BMI 16- 16.99
Severe: BMI 15-15.99
Extreme: BMI less than 15
 
CLINICAL  FINDINGs
 
Weight loss
; Loss of muscle, subcutaneous fat
Weakness, fatigue
Hypothermia; Acrocyanosis
Pedal edema
Dry skin
, brittle nail
Lanugo-type hairs, increased loss of scalp hair
Dizziness, fainting, palpitations
Bradycardia; Hypotension
, orthostatic pulse difference >25 beats/min.;
Increased risk of heart failure
Early abdominal fullness, digestive problems, constipation
Osteoporosis
Severe dehydration, which may lead to renal failure
Irregular menstruation, amenorrhea
 
AN may be associated with other psychiatric disorders, like – depression, OCD
(Obsessive-Compulsive disorder), phobias, panic disorder, mood disorder,
various personality disorder.
 
 
LABORATORY  FINDINGs
 
↓ Hemoglobin, ↓ WBC, ↓ Platelet
Hypoglycemia
↓ K, Na, Ca, Mg, Phosphorus (Refeeding syndrome)
Metabolic alkalosis (in vomiting) or acidosis (laxative use)
↑ LFT, cholesterol
Hypoproteinemia
Normal or ↓ ESR
Hypercarotenemia
↓ LH, FSH, estrogen
Normal TSH, fT4, ↓ T3 (Sick Euthyroid syndrome)
↓ Bone density
ECG – Sinus bradycardia, low voltage graphs, prolonged QT
interval, flat or inverted T wave, depressed ST segment
 
BULIMIA  NERVOSA
 
Recurrent episodes of binge eating. 
An episode of binge
eating is characterized by both:
         1
. Eating in a discrete period of time (e.g. within any 2
hour period), an amount of food that is definitely larger
than what most individuals would eat in a similar period
of time under similar circumstances
;
         2. A sense of 
lack of control 
over eating during the
episodes (e.g. a feeling that one cannot stop eating or
control what or how much one is eating).
 
Recurrent inappropriate compensatory behaviors to
prevent weight gain, 
such as self-induced vomiting;
misuse of laxatives, diuretics, or other medications;
fasting; or excessive exercise.
 
The binge eating and inappropriate compensatory
behaviors both occur, on average, at least
 once a week
for 3 months
.
 
 
 
Self-evaluation is unduly influenced by body shape and weight.
The disturbance does not occur exclusively during episodes of anorexia nervosa.
 
 
Severity:
 
  
Mild
: 
An average of 
1-3 episodes 
of inappropriate compensatory behaviours per week.
 
  
Moderate: 
An average of 
4-7 episodes 
of inappropriate compensatory behaviours per
week.
 
  
Severe
: 
An average of 
8-13 episodes 
of inappropriate compensatory behaviours per
week.
 
 
 Extreme
: 
An average of 
14 or more episodes 
of inappropriate compensatory behaviours
per week.
 
 
 
Episodic binge eating usually occur in secret; may be triggered by stress, isolation or
negative emotions. Tend to binge on foods high in sugar and refined flour.
More likely to binge alone.
Aware of fat and calories, but less regimented in avoidance than AN.
 
 
 
CLINICAL  FINDINGs
 
Thin to overweight
Russell’s sign
Subconjunctival hemorrhage
Dental enamel erosion
, perimolysis
Esophagitis; Mallory-Weiss tears
Hematemesis
Enlarged salivary glands
 (parotid > submandibular)
Absent gag reflex
Menstrual irregularities
Laxative dependent : rectal prolapse, melena, cathartic colon
May be associated with depression, substance abuse, h/o PTSD; more likely
suicidal than AN
 
 
LABORATORY  FINDINGs
 
    ↑ Serum amylase
     Electrolyte abnormalities – due to diarrhea from heavy laxative use
    ↓ K, Hypochloremic metabolic alkalosis  – from frequent purging
    ECG - Arrhythmia
 
BINGE  EATING  DISORDER
 
Recurrent episodes of binge eating
. An episode of
binge eating is characterized by both:
        1
. 
Eating in a discrete period of time (e.g. within
any 2 hour period), an amount of food that is
definitely larger than what most individuals would
eat in a similar period of time under similar
circumstances
;
        2. A sense of lack of control over eating during the
episodes (e.g. a feeling that one cannot stop eating
or control what or how much one is eating).
Binge eating episodes are associated with 
three or
more 
of the following:
        1. Eating much more 
rapidly than normal
.
        2. Eating until feeling 
uncomfortably full
.
        3. Eating large amounts of food 
when not feeling
physically hungry.
        4. 
Eating alone 
because of feeling embarrassed by
how much one is eating.
        5. Feeling disgusted with oneself, depressed, or
very guilty 
afterwards.
 
 
Marked distress regarding binge eating is present.
The binge eating occurs, on average, at least once a week for 3 months.
The binge eating is not associated with the recurrent use of inappropriate
compensatory behavior as in bulimia nervosa 
and does not occur
exclusively during the course of bulimia nervosa or anorexia nervosa.
 
 
Severity:
 
Mild: 
1-3 
binge eating episodes per week.
 
Moderate:
 4-7 
binge eating episodes per week.
 
Severe: 
8-13 
binge eating episodes per week.
 
Extreme: 
14 or more 
binge eating episodes per week.
 
AVOIDANT/ RESTRICTIVE  FOOD  INTAKE
DISORDER
 
A feeding or eating disturbance 
(e.g. lack of apparent
interest in eating food; avoidance based on the sensory
characteristics of food; concern about aversive
consequences of eating) 
as manifested by persistent
failure to meet appropriate nutritional and/or energy
needs associated with one (or more) of the following:
       1. Significant weight loss (or failure to achieve
expected weight gain or faltering growth in children).
       2. Significant nutritional deficiency.
       3. Dependence on enteral feeding or oral nutritional
supplements.
       4. Marked interference with psychosocial functioning.
 
The disturbance is not better explained by lack of
available food or by an associated culturally sanctioned
practice.
 
 
The eating disturbance does not occur exclusively during the course of anorexia nervosa or
bulimia nervosa, and there is no evidence of a disturbance in the way in which one’s body
weight or shape is experienced.
 
The eating disturbance is not attributable to a concurrent medical condition or not better
explained by another mental disorder. When the eating disturbance occurs in the context of
another condition or disorder, the severity of the eating disturbance exceeds that routinely
associated with the condition or disorder and warrants additional clinical attention.
 
Presents as 3 subtypes –
 
 
 
   
1. Low interest or
limited intake
 
 2. Sensory or limited
variety
 
 3. Fear or aversive
 
PICA
 
Persistent eating of non-nutritive, non-food substances  (e.g., paper, paint,
plaster, soap, clay, wool, ashes, earth etc.) over the period of at least 1 month.
The eating of non-nutritive, non-food substances is inappropriate to the
developmental level of the individual.
The eating behaviour is not part of a culturally supported or socially
normative practice.
If the eating behaviour occurs in the context of another mental disorder
(e.g.,intellectual disability, autism spectrum disorder) or medical condition
(e.g.,pregnancy), it is sufficiently severe to warrant additional clinical
attention
.
 
 
Onset can occur in childhood. Pica can occur in otherwise normally
developing children.
It is the only FED which can be diagnosed simultaneously with other ED.
Treatment
 – Combined behavioral, social and medical approaches.
                          Specific treatment for the ingested items
, e.g., Lead toxicity,
Iron-deficiency anemia, Parasitic infestation, Surgical intervention for gastric
bezoar from ingestion of hair etc.
 
RUMINATION  DISORDER
 
Repeated regurgitation of food over the period of at least 1 month. Regurgitated
food may be re-chewed, re-swallowed, or spit out.
Not attributable to an associated gastrointestinal or other medical condition (e.g.,
reflux).
Does not occur exclusively during the course of anorexia nervosa, bulimia nervosa,
binge-eating disorder, or avoidant/restrictive food intake disorder.
If symptoms occur in the context of another mental disorder (e.g., intellectual
disability), they are sufficiently severe to warrant additional clinical attention.
 
 
Rumination is poorly understood but believed to be 
self-stimulatory
.
Weight loss, failure to reach expected weight, malnutrition may occur.
Behavioral treatment by reinforcing correct eating behavior while minimizing
attention to rumination.
Aversive conditioning techniques 
are more useful in adolescents.
 
OTHER  SPECIFIED  FEEDING  OR
EATING  DISORDER
 
Symptoms characteristic of a feeding or eating disorder that
cause clinical distress or impairment in social, occupational, or
other important areas of functioning predominate.
 
However DO NOT meet the full criteria for any of the
disorders in the feeding and eating disorders diagnostic class.
 
This category can also be used in situations to communicate
the specific reason the presentation does not meet the criteria
for a specific eating disorder.
 
This is done by recording “other specified feeding or eating
disorder” followed by the specific reason e.g. “bulimia
nervosa- low frequency”.
 
UNSPECIFIED  FEEDING  OR  EATING
DISORDER
 
 Symptoms characteristic of a feeding and eating disorder &
cause clinical significant distress or impairment in social,
occupational or other important areas of functioning
predominate.
 
•     However DO NOT meet the full criteria for any of the
disorders in the feeding and eating disorders diagnostic class.
 
•     Used when the clinician chooses not to specify the reason that
criteria are not met for a specific feeding and eating disorder.
 
•     This includes times when there is insufficient information to
make a more specific diagnosis (e.g. in emergency room
setting).
 
ETIOLOGY  AND  PATHOGENESIS
 
Multidimensional
 
Genetic/ Biological Factors 
– Both AN and BN tend to run in families.
   - Serotonin may play a role in BN
   - Dopamine in restrained eating
 
Psychological Factors – 
Low self-esteem/ Poor body image
   - Overvaluation of appearance
   - Inadequate coping machanisms
   
- Feeling of failure/ feeling out of control
   
- Response to change (puberty); stress (sports, dance)
 
Social/ Cultural Factors – 
Social norms for obtaining “the perfect body”
    
- Peer pressure
    
- Social media hype of thin body image
 
Interpersonal Factors – 
Unresolved family conflicts
    
- Body relevant insult and teasing
    
- History of physical or sexual abuse
 
RISK  FACTORs  FOR  “FED”
 
A family history of FED, substance use or mood disorder
 
Poor communication and conflict resolution at home
 
Low self-esteem and self-confidence
 
Personality traits such as perfectionism
 
Family values or cultural norms about having a specific body size
 
Participation in sports that focus on body shape and size such as ballet
dancing, gymnastics, track events etc.
 
Early puberty
 
Abusive relations that cause emotional distress and feeling of loss of
control such as physical or sexual abuse
 
EVALUATION
 
Thorough history/ interview – There are 
different questionnaire
, like
   - Eating Disorder Inventory (EDI)
   - Eating Disorder Examination Interview (EDE)
   - Eating Attitudes Test (EAT)
   - SSHADES
 
Specific signs and symptoms as discussed previously
Specific laboratory investigations
 
 In another type of assessment, individuals with AN are shown line
drawings of persons with varying body weight and asked to pick the
closest one.

     CBT and FBT (Maudsley approach)
     DBT – Used in binge-purge subtype
     Individual psychodynamic (not effective)
Inpatient care – Prognosis depends on duration of illness, age and type of
treatment.
Antidepressants, Antipsychotics – not much effective
Use of zinc, cyproheptadine
Hormone therapy - controversial
However, patients are five times more likely to die prematurely and at
much higher risk for suicide than non-eating disorder patients which
underscores the need for early screening and treatment.

TREATMENT  OF  “BN”
 
Outpatient care – Break the binge-purge cycle →
intensive counseling and regular follow-up.
    CBT most effective.
 FBT also useful.
SSRIs
TCA - ↓binge, improve mood.
Antiepileptic drug (topiramate)
Inpatient care - Nutritional rehabilitation, replenishing
electrolytes, preventing further medical or psychiatric
complications.
If untreated, BN may lead to long-term complications, e.g.
Arrhythmia, dental problems, bleeding from esophagus.
Mortality less common than AN.
Poor prognosis if associated with sexual abuse, depression
or substance abuse.
 
 
TREATMENT  OF  “BED”
 
CBT
 (CBT+Orlistat > CBT)
DBT and group therapy
SSRI
 – ↓binge freqency
TCA
 – ↓binge frequency, weight and depression
Antieileptics (topiramate and zonisamide), SNRI, Atomoxetine -
↓binge frequency, weight
 
TREATMENT  OF  “ARFID”
 
    CBT
    Structure meal time
    Exposure therapy 
– Helps to tolerate anxiety-provoking foods or
the physical process of consuming the feared food or neophobia.
    FBT
    
Nutritional rehabilitation 
– Volume before variety
.   Supplementation of 
specific vitamins or minerals
    Cyproheptadine – in low-weight patients
    Lorazepam, Olanzapine – more trials needed.
 
 
PREVENTION
 
Prevention is difficult
Target older adolescents and college-age-
women
Psychoeducational approaches
De-emphasizing socio-cultural influences
Risk factor identification and intervention
to alter these factors
 
 
 
TAKE  HOME  MESSAGE
 
FEDs are potentially life threatening
 
Cause considerable psychological distress apart
from the physical complications
 
Early diagnosis and treatment are of paramount
importance
 
More awareness is needed in our society
 
Social media can play a vital role

Eating disorders in children, such as anorexia nervosa, bulimia nervosa, and binge eating disorder, are complex biopsychosocial disorders characterized by dysfunctional patterns of cognition and weight control behaviors. They result in significant physical, psychological, and social complications. These disorders have been on the rise in India over the last two decades, impacting older children and adolescents. The classification in DSM-5 includes specific diagnoses like ARFID and umbrella diagnoses like OSFED and UFED, highlighting the importance of early identification, intervention, and treatment to address these challenging issues.

  1. EATING DISORDERS IN EATING DISORDERS IN CHILDREN CHILDREN DR. SOUMI KUNDU Assistant Professor Department of Pediatrics KPCMCH, Kolkata

  2. Common Eating Problems in Children Common Eating Problems in Children Food refusal Inappropriate food for age Poor appetite Picky eaters Faulty feeding practices These can be easily treated with parents education, few feeding modifications. But Eating Disorders on the other hand are much more difficult to treat.

  3. EATING DISORDERs EATING DISORDERs

  4. Eating disorders (EDs) are complex biopsychosocial disorders characterized by dysfunctional patterns of cognition and weight control behaviors that result in significant physical, psychological and social complications. Affects older children and adolescents. Incidence is increasing in India over the last two decades.

  5. ED ED FED FED Eating Disorders (ED) this term has been replaced with Feeding and Eating Disorders (FED) in the 5th revision of the American Psychiatric Association s Diagnostic and Statistical Manual of Mental Disorders (DSM-5) published in 2013 and in the 11th revision of the World Health Organisation s International Statistical Classification of Diseases (ICD-11) and Related Health Problems published in 2019. American Psychiatric Association. Diagnostic and Statistical Manual of Mental Disorders (5th edn) (DSM-5). Washington, DC: American Psychiatric Association; 2013. World Health Organization. International Statistical Classification of Diseases and Related Health Problems, 11th Revision(ICD-11). Geneva: World Health Organization; 2019.

  6. CLASSIFICATION CLASSIFICATION In DSM-5, FED comprises of eight diagnoses Six specific diagnoses : 1. Anorexia Nervosa (AN) 2. Bulimia Nervosa (BN) 3. Binge Eating Disorder (BED) 4. Avoidant/Restrictive Food Intake Disorder (ARFID) 5. Pica and 6. Rumination Disorder (RD) Two umbrella diagnoses : Other Specified Feeding or Eating Disorder (OSFED) and Unspecified Feeding or Eating Disorder (UFED) 1. 2.

  7. ANOREXIA NERVOSA ANOREXIA NERVOSA 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 minimally expected. Intense fear of gaining weight or of becoming fat, or persistent behaviour that interferes with weight gain, even though at a significantly low weight.

  8. 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. Two types Restricting type: During the last three months, the individual has not engaged in recurrent episodes of binge eating or purging behaviour (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. Binge-eating/purging type: During the last three 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). Severity: Mild: BMI more than 17 Moderate: BMI 16- 16.99 Severe: BMI 15-15.99 Extreme: BMI less than 15

  9. CLINICAL FINDINGs CLINICAL FINDINGs Weight loss; Loss of muscle, subcutaneous fat Weakness, fatigue Hypothermia; Acrocyanosis Pedal edema Dry skin, brittle nail Lanugo-type hairs, increased loss of scalp hair Dizziness, fainting, palpitations Bradycardia; Hypotension, orthostatic pulse difference >25 beats/min.; Increased risk of heart failure Early abdominal fullness, digestive problems, constipation Osteoporosis Severe dehydration, which may lead to renal failure Irregular menstruation, amenorrhea AN may be associated with other psychiatric disorders, like depression, OCD (Obsessive-Compulsive disorder), phobias, panic disorder, mood disorder, various personality disorder.

  10. LABORATORY FINDINGs LABORATORY FINDINGs Hemoglobin, WBC, Platelet Hypoglycemia K, Na, Ca, Mg, Phosphorus (Refeeding syndrome) Metabolic alkalosis (in vomiting) or acidosis (laxative use) LFT, cholesterol Hypoproteinemia Normal or ESR Hypercarotenemia LH, FSH, estrogen Normal TSH, fT4, T3 (Sick Euthyroid syndrome) Bone density ECG Sinus bradycardia, low voltage graphs, prolonged QT interval, flat or inverted T wave, depressed ST segment

  11. BULIMIA NERVOSA BULIMIA NERVOSA Recurrent episodes of binge eating. An episode of binge eating is characterized by both: 1. Eating in a discrete period of time (e.g. within any 2 hour period), an amount of food that is definitely larger than what most individuals would eat in a similar period of time under similar circumstances; 2. A sense of lack of control over eating during the episodes (e.g. a feeling that one cannot stop eating or control what or how much one is eating). Recurrent inappropriate compensatory behaviors to prevent weight gain, such as self-induced vomiting; misuse of laxatives, diuretics, or other medications; fasting; or excessive exercise. The binge eating and inappropriate compensatory behaviors both occur, on average, at least once a week for 3 months.

  12. Self-evaluation is unduly influenced by body shape and weight. The disturbance does not occur exclusively during episodes of anorexia nervosa. Severity: Mild: An average of 1-3 episodes of inappropriate compensatory behaviours per week. Moderate: An average of 4-7 episodes of inappropriate compensatory behaviours per week. Severe: An average of 8-13 episodes of inappropriate compensatory behaviours per week. Extreme: An average of 14 or more episodes of inappropriate compensatory behaviours per week. Episodic binge eating usually occur in secret; may be triggered by stress, isolation or negative emotions. Tend to binge on foods high in sugar and refined flour. More likely to binge alone. Aware of fat and calories, but less regimented in avoidance than AN.

  13. CLINICAL FINDINGs CLINICAL FINDINGs Thin to overweight Russell s sign Subconjunctival hemorrhage Dental enamel erosion, perimolysis Esophagitis; Mallory-Weiss tears Hematemesis Enlarged salivary glands (parotid > submandibular) Absent gag reflex Menstrual irregularities Laxative dependent : rectal prolapse, melena, cathartic colon May be associated with depression, substance abuse, h/o PTSD; more likely suicidal than AN LABORATORY FINDINGs LABORATORY FINDINGs Serum amylase Electrolyte abnormalities due to diarrhea from heavy laxative use K, Hypochloremic metabolic alkalosis from frequent purging ECG - Arrhythmia

  14. BINGE EATING DISORDER BINGE EATING DISORDER Recurrent episodes of binge eating. An episode of binge eating is characterized by both: 1. Eating in a discrete period of time (e.g. within any 2 hour period), an amount of food that is definitely larger than what most individuals would eat in a similar period of time under similar circumstances; 2. A sense of lack of control over eating during the episodes (e.g. a feeling that one cannot stop eating or control what or how much one is eating). Binge eating episodes are associated with three or more of the following: 1. Eating much more rapidly than normal. 2. Eating until feeling uncomfortably full. 3. Eating large amounts of food when not feeling physically hungry. 4. Eating alone because of feeling embarrassed by how much one is eating. 5. Feeling disgusted with oneself, depressed, or very guilty afterwards.

  15. Marked distress regarding binge eating is present. The binge eating occurs, on average, at least once a week for 3 months. The binge eating is not associated with the recurrent use of inappropriate compensatory behavior as in bulimia nervosa and does not occur exclusively during the course of bulimia nervosa or anorexia nervosa. Severity: Mild: 1-3 binge eating episodes per week. Moderate: 4-7 binge eating episodes per week. Severe: 8-13 binge eating episodes per week. Extreme: 14 or more binge eating episodes per week.

  16. AVOIDANT/ RESTRICTIVE FOOD INTAKE AVOIDANT/ RESTRICTIVE FOOD INTAKE DISORDER DISORDER A feeding or eating disturbance (e.g. lack of apparent interest in eating food; avoidance based on the sensory characteristics of food; concern about aversive consequences of eating) as manifested by persistent failure to meet appropriate nutritional and/or energy needs associated with one (or more) of the following: 1. Significant weight loss (or failure to achieve expected weight gain or faltering growth in children). 2. Significant nutritional deficiency. 3. Dependence on enteral feeding or oral nutritional supplements. 4. Marked interference with psychosocial functioning. The disturbance is not better explained by lack of available food or by an associated culturally sanctioned practice.

  17. The eating disturbance does not occur exclusively during the course of anorexia nervosa or bulimia nervosa, and there is no evidence of a disturbance in the way in which one s body weight or shape is experienced. The eating disturbance is not attributable to a concurrent medical condition or not better explained by another mental disorder. When the eating disturbance occurs in the context of another condition or disorder, the severity of the eating disturbance exceeds that routinely associated with the condition or disorder and warrants additional clinical attention. Presents as 3 subtypes 1. Low interest or limited intake 3. Fear or aversive 2. Sensory or limited variety

  18. PICA PICA Persistent eating of non-nutritive, non-food substances (e.g., paper, paint, plaster, soap, clay, wool, ashes, earth etc.) over the period of at least 1 month. The eating of non-nutritive, non-food substances is inappropriate to the developmental level of the individual. The eating behaviour is not part of a culturally supported or socially normative practice. If the eating behaviour occurs in the context of another mental disorder (e.g.,intellectual disability, autism spectrum disorder) or medical condition (e.g.,pregnancy), it is sufficiently severe to warrant additional clinical attention. Onset can occur in childhood. Pica can occur in otherwise normally developing children. It is the only FED which can be diagnosed simultaneously with other ED. Treatment Combined behavioral, social and medical approaches. Specific treatment for the ingested items, e.g., Lead toxicity, Iron-deficiency anemia, Parasitic infestation, Surgical intervention for gastric bezoar from ingestion of hair etc.

  19. RUMINATION DISORDER RUMINATION DISORDER Repeated regurgitation of food over the period of at least 1 month. Regurgitated food may be re-chewed, re-swallowed, or spit out. Not attributable to an associated gastrointestinal or other medical condition (e.g., reflux). Does not occur exclusively during the course of anorexia nervosa, bulimia nervosa, binge-eating disorder, or avoidant/restrictive food intake disorder. If symptoms occur in the context of another mental disorder (e.g., intellectual disability), they are sufficiently severe to warrant additional clinical attention. Rumination is poorly understood but believed to be self-stimulatory. Weight loss, failure to reach expected weight, malnutrition may occur. Behavioral treatment by reinforcing correct eating behavior while minimizing attention to rumination. Aversive conditioning techniques are more useful in adolescents.

  20. OTHER SPECIFIED FEEDING OR EATING DISORDER Symptoms characteristic of a feeding or eating disorder that cause clinical distress or impairment in social, occupational, or other important areas of functioning predominate. However DO NOT meet the full criteria for any of the disorders in the feeding and eating disorders diagnostic class. This category can also be used in situations to communicate the specific reason the presentation does not meet the criteria for a specific eating disorder. This is done by recording other specified feeding or eating disorder followed by the specific reason e.g. bulimia nervosa- low frequency .

  21. UNSPECIFIED FEEDING OR EATING DISORDER Symptoms characteristic of a feeding and eating disorder & cause clinical significant distress or impairment in social, occupational or other important areas of functioning predominate. However DO NOT meet the full criteria for any of the disorders in the feeding and eating disorders diagnostic class. Used when the clinician chooses not to specify the reason that criteria are not met for a specific feeding and eating disorder. This includes times when there is insufficient information to make a more specific diagnosis (e.g. in emergency room setting).

  22. ETIOLOGY AND PATHOGENESIS ETIOLOGY AND PATHOGENESIS Multidimensional Genetic/ Biological Factors Both AN and BN tend to run in families. - Serotonin may play a role in BN - Dopamine in restrained eating Psychological Factors Low self-esteem/ Poor body image - Overvaluation of appearance - Inadequate coping machanisms - Feeling of failure/ feeling out of control - Response to change (puberty); stress (sports, dance) Social/ Cultural Factors Social norms for obtaining the perfect body - Peer pressure - Social media hype of thin body image Interpersonal Factors Unresolved family conflicts - Body relevant insult and teasing - History of physical or sexual abuse

  23. RISK FACTORs FOR FED RISK FACTORs FOR FED A family history of FED, substance use or mood disorder Poor communication and conflict resolution at home Low self-esteem and self-confidence Personality traits such as perfectionism Family values or cultural norms about having a specific body size Participation in sports that focus on body shape and size such as ballet dancing, gymnastics, track events etc. Early puberty Abusive relations that cause emotional distress and feeling of loss of control such as physical or sexual abuse

  24. EVALUATION EVALUATION Thorough history/ interview There are different questionnaire, like - Eating Disorder Inventory (EDI) - Eating Disorder Examination Interview (EDE) - Eating Attitudes Test (EAT) - SSHADES Specific signs and symptoms as discussed previously Specific laboratory investigations In another type of assessment, individuals with AN are shown line drawings of persons with varying body weight and asked to pick the closest one.

  25. SAMPLE SCREENING QUESTIONs FOR SAMPLE SCREENING QUESTIONs FOR SUSPECTED FED SUSPECTED FED Why do you think that you are losing weight? How long has this been going on? What is your highest and lowest weight? What is your usual diet? Do you eat breakfast, lunch and dinner? Do you skip meals? Have you changed your intake? Is there anything that you do not eat or feel guilty eating? Have you ever tried to restrict your intake or consumed large quantities of food at one time? Have you tried to vomit, use laxatives or other diet pills? Do you exercise regularly? How much at one time? When was your last menstrual history and how often do you have your menses? Have you felt sad, depressed, suicidal or anxious? Are you on social media? If so, what do you use and how often? Are any of your peers dieting or concerned about their weight? When you look in the mirror what do you see? Are there certain parts of your body that you are unhappy with? How would you feel if you gained weight? Have you had any dizziness, weakness, fatigue or difficulty focusing? Have you noticed any cold intolerance or irregular menses? Do you have dry skin and/ or Lanugo (fine hair)? Have you had any bloating, heartburn, abdominal pain, constipation, diarrhea, chest pain, joint pains or muscle cramps? Abraham A. Eating Disorders in Adolescents.

  26. DIFFERENTIAL DIAGNOSIS DIFFERENTIAL DIAGNOSIS Malignancy, CNS tumors Endocrinopathies, e.g. Hyperthyroidism Occult chronic infection Malabsorption, e.g. Inflammatory bowel disease, celiac disease Stimulant abuse Type 1 diabetes mellitus Addison disease Depression Obsessive-compulsive disorder

  27. COMPLICATIONs COMPLICATIONs Cardiac complications Ventricular dysrhythmias, reduced myocardial contractility Nutritional deficiencies Refeeding syndrome Suicidal tendency, depression, anxiety Hypothalamic dysfunction Reduced gonadal function Osteoporosis Hypertension, Diabetes mellitus, gall-bladder disease (associated with BED )

  28. TREATMENT TREATMENT Multidisciplinary care Inpatient or outpatient treatment Nutrition Physical activity Cognitive Behavioral Therapy(CBT) Family Based Therapy(FBT) Dialectical Behavioral Therapy(DBT) Interpersonal Psychotherapy(ITP) Drug therapy Selective Serotonin Reuptake Inhibitors(SSRI), Tricyclic antidepressants(TCA), Serotonin Norepinephrine Reuptake Inhibitor(SNRI), Anticonvulsants Alternate therapies Yoga, mindfulness

  29. TREATMENT OF AN TREATMENT OF AN Treatment of AN comprises of a specific program involving three main phases Weight restoration Treatment of psychological disturbances Long term remission. Outpatient care In mild to moderate cases. CBT and FBT (Maudsley approach) DBT Used in binge-purge subtype Individual psychodynamic (not effective) Inpatient care Prognosis depends on duration of illness, age and type of treatment. Antidepressants, Antipsychotics not much effective Use of zinc, cyproheptadine Hormone therapy - controversial However, patients are five times more likely to die prematurely and at much higher risk for suicide than non-eating disorder patients which underscores the need for early screening and treatment.
