Bulimia Nervosa
Characterized by recurrent episodes of uncontrolled excessive eating followed by compensatory actions to remove the food
ecurrent episodes of uncontrolled excessive (binge) eating followed by compensatory actions to remove the food (Ex: vomiting, laxative abuse, and escessive exercises)
Anorexia nervosa
Characterized by recurrfent food refusal, leading to dangerously low body weight
recurrent food refusal, leading to dangerously low body weight
Binge Eating disorder
Pattern of eating involving very rapid, distress-inducing consumption of large amounts of food that are not followed by purging behaviors
pattern of eating involving distress-inducing binges not followed by purging behaviors
Criteria for Bulimia Nervosa
-Recurrent episodes of eating, in a discrete period of time an amount of food that is definetly larger than most people would eat during a similar period of time under similar circumstances AND a sense of lack of control over eating during the episode
-Recurrent inappropriate compensatory behaviors in order to prevent weight gain (ex: self-induced vomiting, misuse of laxatives, diuretics, other medications, fasting, or excessive exercise)
-Binge eating and inappropriate compensatory behaviors both occur on average 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
Criteria for Anorexia Nervosa
-Restriction of energy intake relative to requirements, leading to a significantly low body weight (by age, sex, developmental trajectory, physical health)
-Intense fear of gaininig weight or of becoming fat, or persistent behavior 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 of self-evaluation, or persistent lack of recognition of the seriousness of the current low body weight
Significantly low weight
weight that is less than minimally normal or, for children and adolescents, less than that minimally expected
Two subtypes of Anorexia
Restricting and Binge-eating/purge type
Restricting type of Anorexia Nervose Criteria
-During the past 3 months, the individual has not engaged in recurrent episodes of binge eating or purging behavior (i.e., self-induced vomiting or the misuse of laxatives, diuretics, or enemas)
-Weightloss is accomplished primarily through dieting, fasting, and/or excessive exercise
Binge-eating/purging type of Anorexia Nervosa Criteria
-During the past 3 months, the individual has engaged in recurrent episodes of binge eating or purging behavior (i.e. self-induced vomiting or the misuse of laxatives, diuretics, or enemas)
Binge-Eating Criteria
-Recurrent episodes of eating, in a discrete period of time, an amount of food that is definitely larger than what most people would eat in a similar period of time under similar circumstances AND a sense of lack of control over eating during the episode (e.g. a feeling that one cannot stop eating or control what or how much one is eating)
-Episodes are associated with at least 3 of the following: eating much more rapidly than normal, eating until feeling uncomfortably full, eating large amounts of food when not feeling physically hungry, eating alone because of feeling embarrassed by how much one is eating, feeling disgusted with oneself, depressed, or very guilty afterward
-Marked distres regarding binge eating being 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
Bingeing
-hallmark of bulimia nervosa and binge eating disorder
-Eating excess amounts of food in a discrete period of time
-Eating is perceived as uncontrollable
-May be associated with guilt, shame, or regret or particularly stressful times
-May hide behavior from family members
-Foods consumed are often high in sugar, fat, or carbohydrates
Examples of Purging
vomiting, laxatives, diuretics
Causes of Eating Disorders: Social Dimensions
-Societal emphasis on thinness -> Prioritization of being perceived as thin over being healthy -> Dieting
-Glorificatiton of slenderness
-Close Friendships group sharing similar attitudes concerining body image, dietary restraint, and extreme weight-loss behaviors
-Settings where social pressures are exceptionally intense for being thin, such as ballet schools or among athletes or gymnasts
-Failure to thrive syndrome
-Dieting in an early age is linked to an increased risk of future dietary attempts and developing eating disorders (dietary attempts in adolescent girls result in weight gain, stress, and heightened preoccupation with food & eating during the dieting
Glorification of slenderness
the extent to which women internalize media messages glorifying thinness increseases the risk of developing eating disorders
-Gender differences in body image perceptions
Failure to thrive syndrome
Toddlers does not gain weight at the expected rate
Parents put their toddlers on diets in the hope of preventing obesity
Causes of Eating Disorders
Family interaction before eating disorders
-Success orientation, ambition, perfectionism, concern for external appearances, desire to maintain harmony
-Not the primary causes of eating disorders
Family dynamics after eating disorder can quickly deteriorate
-Physical punishment from parents is linked with poorer outcomes for the eating disorder
Reverse Anorexia Nervosa
men reported concern about looking small, even though they were muscular
-prone to steroids
Causes of Eating disorders: Biological Dimension
Inherited vulnerability
-unstable or excessive neurobiological response to stress associated with impulsive eating
Genetic influence
-Response emotionally to stressful events, impulsive eating, perfectionism, negative affect
Hypothalmus -> regulating eating
Reduced Serotonin activity-> impulsivity & binge eating
Ovarian hormones-> Hormone-responsive genes
-Speculate onset of puberty & hormonal changes may “turn on” certain risk genes
-Emotional or binge eating peaked in postovulatory phase (menstrual)
Causes of Eating Disorders: Psychological Dimension
-Anxiety focused on appearance
-Distorted body image
-Diminished self-confidence
-Low self-esteem
-High perfectionism
-Imposter Syndrome
-Distortions in the perception of body image
-Mood intolerance
Imposter syndrome
-Perceive self as a fraud
-False any impressions made of being adequate self-sufficient, or worthwhile
-Heightened levels of social anxiety
Mood intolerance
extreme regulation tactics for mood
Treatment of Bulimia Nervosa
-Psychoeducation about the physical effects of binge eating and purging, the inefficacy of vomiting and laxative abuse for weight control
-Discussing the adverse effects of dieting
Behavioral component
-Adopting a structured eating schedule, consuming small, manageable portions five or six times daily with no more than a 3-hour interval between any planned meals and snacks
-introducing forbidden foods into diet
-organizing activities to avoid solitary time
Cognitive Component
-coping strategies
-Monitoring and confronting the cognitions that accompany the binge episodes and purging episodes. Then the therapist helps the client confront these cognitions and develop more adaptive attitudes toward weight and body shape. Afvter meals in the initial stagees of treatment is also an important aspect of the treatment
-Cognitive-behavioral therapy-enhances (CBT-E) -> Interpersonal therapy & Psychoanalytic psychotherapy
-Family therapy has also proven effective
Cognitive-behavioral therapy-enhances (CBT-E)
-Treatment of choice
-Principal focus is on the distorted evaluation of body shape and weight and on maladaptive attempts to control weight in the form of strict dieting and compensatory activities
Treatment of Binge Eating Disorder
-Previously used medications for obesity are now not recommended
Psychological treatment
-CBT (effective)
-Interpersonal psychotherapy (equally effective as CBT)
-Self-help techniques (effective)
