Medical disorders:  Kleine-Levin or Kluver-Bucy syndromes = binge eating-associated neurological disorders, differenbt from bulimia
When to hospitalize for EDs...
Trend toward fewer and shorter hospitalizationsInsurance driven vs data drivenMedical vs psychiatric issuesGeneralizability of treatmentEgo-syntonic nature of anorexia
Anorexic persons with metabolic and electrolyte imbalances are at risk of?
Heart failure or circulatory collapse
cognitive and physiological model of eating disorders
inheritied set point that regulates weight and metabolismdistorted beliefs about body shapefaulty beliefs about weight regulation
People with anorexia nervosa may also present these psychological problems
Depression, anxiety, low self-esteem, insomnia, substance abuse, OCD, including exercising compulsively
Overall Aims of Treatment for AN
Weight gain of .5 to 2lbs per weekRestoration of normal weightRestoration of normal menstruation

skin that is rough, dry, and cracked. Brittle nails.
Cold hands and feet that may have a bluish color.
loss of hair from scalp, and lanugo on trunk, extremities, and face
Affect Regulation
regulation of emotions,

thyroid disease
refusal to maintain normal body weightsevere volunatry restriction of food intake resulting from : fear or weight gain and disturbed body image
S&S of Bulimia Nervosa
-dental caries(vomiting)-parotid swelling(increased serum amylade levels)-gastric dilation, rupture (binge eating)-scars on hand=Russell's sign (self indused vomiting) hypokalemia,hyponatremia,elec imbalance(induced vomiting,laxative)

Co morbidity:
- with anorexia; Cluster C d/o= avoidant and OCD -with bulimia; Cluster B and C d/o= borderline and avoidant.-Hx of sexual abuse is more common-may be related to depression
Family Environment Factors in AN
Limited Ability to Tolerate Psychological Tension or Disharmony Emphasis on Propriety and Rule-MindednessOverdirection of Child/Discouragement of AutonomyPoor Conflict Resolution Skills
Object constancy
When a baby realizes that objects are permanent and still exist even if not in plain view (e.g. mom will come back)
Eating Disorder Causes (Genetic)
Personality and biological traits that govern hormones, hunger and satiety lead to eating disorders.
Risk Factors for ED
Age 13-18Female (although # of males increasing)Obesity Avoidance/Fear of Gaining WeightEarly Puberty and MaturationRestrained EatingUnhealthy Weight Control MeasuresDifficulty Identifying and Expressing EmotionsHistory of DepressionNeed for PerfectionLow Self-EsteemLack of Adequate Coping SkillsAlcohol/Substance AbuseSexual or Physical Abuse HistoryEarly Dating/Confusion about Appropriate BehaviorIll Health or Early Pregnancy
lack of conflict resolution
avoid conflict or are in chronic conflictbulimia
Binge Eating Disorder
Binge eating at least 2 days a week for 6 months
Not associated w/ any of the regular compensatory behaviors (purging, fasting, exercise) of AN or BN
Eating Disorders Not Otherwise Specified (EDNOS)
Most eating disorders are grouped as EDNOS and include diseases not specifically named. This includes disorders that contain elements of anorexia and bulimia or that do not meet the weight range requirement for anorexia or the binging restriction of bulimia.
3 Layers of an Eating Disorder
1) deficits in self concept2) body image disturbances3) eating and biologic symptoms/disturbances
After forced vomiting, how many calories have ben absorbed?
About half of the calories have been absorbed.
factors: personality

factors: cognitive
dichotomous thinkingobsession with physical appearancenegative body image
Medical Complications of Bulimia
HypO-calcemia, -chloremia, -kalemia
Metabolic alkalosis (if vomiting) or acidosis (if using laxatives)
Electrolyte disturbances
Serum transaminases elevated
Parotid gland enlargement, elevated amylase
esophageal tears (rare but serious)
anorexia subtypes
restricting type and binge eating/purging type
S&S of Anorexia Nervosa
-low weight(caloric restriction)-yellow skin(hypercarotenemia)-cold extremities(starvation)-peripheral edema (hypoalbuminemia)-low BP,P, and temp (electrolyte imbalance)-abnormal lab values (low thyroxine levels)-constipation-amenorrhea-lanugo
Produced in fat cells In direct proportion to the amount of stored energyProvides feedback to hypothalamic appetite centersRegulates body weightPromotes satietyDecreases appetiteDecreases the synthesis of fatIncreases the body's ability to burn fatObese peopleA surplus of leptin, but unresponsive to effects
Object relations
development of relations with the objects and people around you (psychodynamic theory of development: 3 months)

Treating Anorexia: An Evolution

Bulimia Nervosa Symptoms
Obviously there is tooth decay and mouth sores. Less obviously there is semi-starvation followed by binges where the binge may be more than 3500 calories in less than 2 hours that is followed by guilt that leads to purging or fasting. Over time results in inflammation, broken blood vessels from vomiting, electrolyte imbalance and menstrual irregularities.
Biogenetic Factors in AN
Increased Risk of AN in 1rst Biological Degree RelativesMay Have Increased Levels of Serotonin and May Diet in an Attempt to Decrease Anxiety, Obsessiveness and Perfectionism Starving enduces Endorphins/Cortisol
An eating disorder that is seen in men and is considered reverse anorexia nervosa
muscle dysmorphobia
Family Environment Factors in BN
Substance Abuse (Parents use to deal with problems)Obesity and/or MigrainesAffective Disorders (Depression etc.)
