Eating disorders


  • Current Western beauty standards equate thinness with health and beauty

  • There has been a rise in eating disorders in the past three decades

    • The core issue is a morbid fear of weight gain

  • Two main diagnoses:

    • Anorexia nervosa

    • Bulimia nervosa

Anorexia nervosa


  • The main symptoms of anorexia nervosa are:

    • A refusal to maintain more than 85% of normal body weight

    • Intense fears of becoming overweight

    • A distorted view of body weight and shape

    • Amenorrhea

Anorexia nervosa1

Anorexia Nervosa

  • There are two main subtypes:

    • Restricting type

      • Lose weight by restricting “bad” foods, eventually restricting nearly all food

      • Show almost no variability in diet

    • Binge-eating/purging type

      • Lose weight by vomiting after meals, abusing laxatives or diuretics, or engaging in excessive exercise

        • Like those with bulimia nervosa, people with this subtype may engage in eating binges

Anorexia nervosa2

Anorexia Nervosa

  • About 90–95% of cases occur in females

  • The peak age of onset is between 14 and 18 years

  • Around 0.5% of females in Western countries develop the disorder

    • Many more display some symptoms

Anorexia nervosa3

Anorexia Nervosa

  • The “typical” case:

    • A normal to slightly overweight female has been on a diet

    • Escalation to anorexia nervosa may follow a stressful event

      • Separation of parents

      • Move or life transition

      • Experience of personal failure

    • Most patients recover

      • However, about 2 to 6% become seriously ill and die as a result of medical complications or suicide

Anorexia nervosa the clinical picture

Anorexia Nervosa: The Clinical Picture

  • The key goal for people with anorexia nervosa is thinness

    • The driving motivation is FEAR:

      • Of becoming obese

      • Of losing control of body shape and weight

Anorexia nervosa the clinical picture1

Anorexia Nervosa: The Clinical Picture

  • Despite their dietary restrictions, people with anorexia are extremely preoccupied with food

    • This includes thinking and reading about food and planning for meals

    • This relationship is not necessarily causal

      • It may be the result of food deprivation, as evidenced by the famous.

Anorexia nervosa the clinical picture2

Anorexia Nervosa: The Clinical Picture

  • People with anorexia nervosa also demonstrate distorted thinking:

    • Often have a low opinion of their body shape

    • Tend to overestimate their actual proportions

      • Adjustable lens assessment technique – overestimate size by 20%

    • Hold maladaptive attitudes and beliefs

      • “I must be perfect in every way”

      • “I will be a better person if I deprive myself”

      • “I can avoid guilt by not eating”

Anorexia nervosa the clinical picture3

Anorexia Nervosa: The Clinical Picture

  • People with anorexia may also display certain psychological problems:

    • Depression (usually mild)

    • Anxiety

    • Low self-esteem

    • Insomnia or other sleep disturbances

    • Substance abuse

    • Obsessive-compulsive patterns

    • Perfectionism

Anorexia nervosa problems

Caused by starvation:


Low body temperature

Low blood pressure

Body swelling

Reduced bone density

Slow heart rate

Metabolic and electrolyte imbalance

Dry skin, brittle nails

Poor circulation


Anorexia Nervosa: Problems

Bulimia nervosa


  • Bulimia nervosa, also known as “binge-purge syndrome,” is characterized by binges:

    • Bouts of uncontrolled overeating during a limited period of time

      • Often objectively more than most people would/could eat in a similar period

Bulimia nervosa1

Bulimia Nervosa

  • The disorder is also characterized by compensatory behaviors, which mark the subtype of the condition:

    • Purging-type bulimia nervosa

      • Vomiting

      • Misusing laxatives, diuretics, or enemas

    • Nonpurging-type bulimia nervosa

      • Fasting

      • Exercising excessively

Bulimia nervosa2

Bulimia Nervosa

  • Like anorexia nervosa, about 90–95% of bulimia nervosa cases occur in females

  • The peak age of onset is between 15 and 21 years

  • Symptoms may last for several years with periodic letup

Bulimia nervosa3

Bulimia Nervosa

  • Patients are generally of normal weight

    • May be slightly overweight

    • Often experience weight fluctuations

  • “Binge-eating disorder” may be a related diagnosis

    • Symptoms include a pattern of binge eating with NO compensatory behaviors (such as vomiting)

    • This condition is not yet listed in the DSM

Bulimia nervosa4

Bulimia Nervosa

  • Teens and young adults have frequently attempted binge-purge patterns as a means of weight loss, often after hearing accounts of bulimia from friends or the media

  • In one study:

    • 50% of college students reported periodic binges

    • 6% tried vomiting

    • 8% experimented with laxatives at least once

Bulimia nervosa binges

Bulimia Nervosa: Binges

  • For people with bulimia nervosa, the number of binges per week can range from 2 to 40

    • Average: 10 per week

  • Binges are often carried out in secret

    • Binges involve eating massive amounts of food rapidly with little chewing

    • Binge-eaters commonly consume more than 1500 calories (often more than 3000 calories) per binge episode

Bulimia nervosa binges1

Bulimia Nervosa: Binges

  • Binges are usually preceded by feelings of tension and/or powerlessness

  • Although the binge itself may be pleasurable, it is usually followed by feelings of extreme self-blame, guilt, depression, and fears of weight gain and “discovery”

Bulimia nervosa compensatory behaviors

Bulimia Nervosa: Compensatory Behaviors

  • After a binge, people with bulimia nervosa try to compensate for and “undo” the caloric effects

  • The most common compensatory behaviors:

    • Vomiting

      • Affects ability to feel satiated  greater hunger and bingeing

    • Laxatives and diuretics

      • Almost completely fail to reduce the number of calories consumed

Bulimia nervosa compensatory behaviors1

Bulimia Nervosa: Compensatory Behaviors

  • Compensatory behaviors may temporarily relieve the negative feelings attached to binge eating

    • Over time, however, a cycle develops in which purging  bingeing  purging…

Bulimia nervosa5

Bulimia Nervosa

  • The “typical” case:

    • A normal to slightly overweight female has been on an intense diet

    • Research suggests that even among normal subjects, bingeing often occurs after strict dieting

      • For example, a study of binge-eating behavior in a low-calorie weight loss program found that 62% of patients reported binge-eating episodes during treatment

Bulimia nervosa vs anorexia nervosa

Bulimia Nervosa vs. Anorexia Nervosa

  • Similarities:

    • Onset after a period of dieting

    • Fear of becoming obese

    • Drive to become thin

    • Preoccupation with food, weight, appearance

    • Elevated risk of self-harm or attempts at suicide

    • Feelings of anxiety, depression, perfectionism

    • Substance abuse

    • Disturbed attitudes toward eating

Bulimia nervosa vs anorexia nervosa1

Bulimia Nervosa vs. Anorexia Nervosa

  • Differences:

    • People with bulimia are more worried about pleasing others, being attractive to others, and having intimate relationships

    • People with bulimia tend to be more sexually experienced

    • People with bulimia display fewer of the obsessive qualities that drive restricting-type anorexia

    • People with bulimia are more likely to have histories of mood swings, low frustration tolerance, and poor coping

Bulimia nervosa vs anorexia nervosa2

Bulimia Nervosa vs. Anorexia Nervosa

  • Differences:

    • People with bulimia tend to be controlled by emotion – may change friendships easily

    • People with bulimia are more likely to display characteristics of a personality disorder

    • Different medical complications:

      • Only half of women with bulimia experience amenorrhea vs. almost all women with anorexia

      • People with bulimia suffer damage caused by purging, especially from vomiting and laxatives

Causes eating disorders

Causes Eating Disorders

  • Most theorists subscribe to a multidimensional risk perspective:

    • Several key factors place individuals at risk

    • More factors = greater risk

    • Leading factors:

      • Sociocultural conditions (societal and family pressures)

      • Psychological problems (ego, cognitive, and mood disturbances)

      • Biological factors

Causes eating disorders societal pressures

Causes Eating Disorders: Societal Pressures

  • Many theorists argue that current Western standards of female attractiveness have contributed to the rise of eating disorders

    • Standards have changed throughout history toward a thinner ideal

Causes eating disorders societal pressures1

Causes Eating Disorders: Societal Pressures

  • Certain groups are at greater risk from these pressures:

    • Models, actors, dancers, and certain athletes

      • Of college athletes surveyed, 9% met full criteria for an eating disorder while another 50% had symptoms

      • 20% of surveyed gymnasts met full criteria for an eating disorder

Causes eating disorders societal pressures2

Causes Eating Disorders:Societal Pressures

  • The socially-accepted prejudice against overweight people may also add to the “fear” and preoccupation about weight

    • About 50% of elementary and 61% of middle school girls are currently dieting

Causes eating disorders family environment

Causes Eating Disorders : Family Environment

  • Families may play a critical role in the development of eating disorders

    • As many as half of the families of those with eating disorders have a long history of emphasizing thinness, appearance, and dieting

    • Mothers of those with eating disorders are more likely to be dieters and perfectionistic themselves

Causes eating disorders family environment1

Causes Eating Disorders : Family Environment

  • Abnormal family interactions and forms of communication within a family may also set the stage for an eating disorder

    • Minuchin cites “enmeshed family patterns” as causal factors of eating disorders

      • These patterns include overinvolvement in, and overconcern about, family member’s lives

      • Such families can be affectionate and loyal but can also foster clinginess and dependency

        • Children are allowed little room for individuality and independence

Causes eating disorders ego deficiencies and cognitive disturbances

Causes Eating Disorders Ego Deficiencies and Cognitive Disturbances

  • Bruch : eating disorders are the result of disturbed mother–child interactions which lead to serious ego deficiencies in the child and to severe cognitive disturbances

Causes eating disorders ego deficiencies and cognitive disturbances1

Causes Eating Disorders :Ego Deficiencies and Cognitive Disturbances

  • Bruch : parents may respond to their children either effectively or ineffectively

    • Effective parents accurately attend to a child’s biological and emotional needs

    • Ineffective parents fail to attend to child’s internal needs; they feed when the child is anxious, comfort when the child is tired, etc.

      • Children who receive such parenting may grow up confused and unaware of their own internal needs; they are unable to identify their own emotions

Causes eating disorders ego deficiencies and cognitive disturbances2

Causes Eating Disorders: Ego Deficiencies and Cognitive Disturbances

  • There is some empirical support for Bruch’s theory from clinical sources

    • People with bulimia eat in response to emotions; many mistakenly think they are also hungry

    • People with eating disorders rely excessively on the opinions, wishes, and views of others

      • They are more likely to worry about how they are viewed, to seek approval, to be conforming, and to feel a lack of life control

Causes eating disorders mood disorders

Causes Eating Disorders : Mood Disorders

  • Many people with eating disorders, particularly those with bulimia nervosa, experience symptoms of depression

    • Theorists believe mood disorders may “set the stage” for eating disorders

Causes eating disorders mood disorders1

Causes Eating Disorders Mood Disorders

  • There is some empirical support for the claim that mood disorders set the stage for eating disorders

    • Many more people with an eating disorder qualify for a clinical diagnosis of major depressive disorder than do people in the general population

    • Close relatives of those with eating disorders seem to have higher rates of mood disorders

    • People with eating disorders, especially those with bulimia nervosa, have low levels of serotonin

    • Symptoms of eating disorders are helped by antidepressant medications

Causes eating disorders biological factors

Causes Eating Disorders : Biological Factors

  • Biological theorists suspect that some people inherit a genetic tendency to develop an eating disorder

    • Consistent with this model:

      • Relatives of people with eating disorders are 6 times more likely to develop the disorder themselves

    • These findings may be related to low serotonin

Causes eating disorders biological factors1

Causes Eating Disorders : Biological Factors

  • Other theorists believe that eating disorders may be related to dysfunction of the hypothalamus

    • Researchers have identified two separate areas that control eating:

      • Lateral hypothalamus (LH)

      • Ventromedial hypothalamus (VMH)

Causes eating disorders biological factors2

Causes Eating Disorders : Biological Factors

  • Some theorists believe that the LH and VMH are responsible for weight set point – a “weight thermostat” of sorts

    • Set by genetic inheritance and early eating practices, this mechanism is responsible for keeping an individual at a particular weight level

      • If weight falls below set point:  hunger,  metabolism  binges

      • If weight rises above set point:  hunger,  metabolism

    • Dieters end up in a fight against themselves to lose weight

Treatments for eating disorders

Treatments for Eating Disorders

  • Eating disorder treatments have two main goals:

    • Correct abnormal eating patterns

    • Address broader psychological and situational factors that have led to and are maintaining the eating problem

      • This often requires the participation of family and friends

Treatments for anorexia nervosa

Treatments for Anorexia Nervosa

  • The initial aims of treatment for anorexia nervosa are to:

    • Restore proper weight

    • Recover from malnourishment

    • Restore proper eating

Treatments for anorexia nervosa1

Treatments for Anorexia Nervosa

  • In the past, treatment took place in a hospital setting; it is now often offered in an outpatient setting

  • In life-threatening cases, clinicians may force tube and intravenous feeding

    • This may breed distrust in the patient and create a power struggle

  • Most common technique now is the use of supportive nursing care and high calorie diets

Treatments for anorexia nervosa2

Treatments for Anorexia Nervosa

  • Therapists use a mixture of therapy and education to achieve this broader goal

    • One focus of treatment is building autonomy and self-awareness

      • Therapists help patients recognize their need for independence and control

      • Therapists help patients recognize and trust their internal feelings

Treatments for anorexia nervosa3

Treatments for Anorexia Nervosa

  • Another focus of treatment is correcting disturbed cognitions, especially client misperceptions and attitudes about eating and weight

    • Using cognitive approaches, therapists correct disturbed cognitions and educate about body distortions

Treatments for anorexia nervosa4

Treatments for Anorexia Nervosa

  • Another focus of treatment is changing family interactions

    • Family therapy is important for anorexia

    • The main issues are often separation and boundaries

Treatments for anorexia nervosa5

Treatments for Anorexia Nervosa

  • The use of combined treatment approaches has greatly improved the outlook for people with anorexia nervosa

    • But even with combined treatment, recovery is difficult

  • The course and outcome of the disorder vary from person to person

Treatments for anorexia nervosa6

Treatments for Anorexia Nervosa

  • Positives of treatment:

    • Weight gain is often quickly restored

      • 83% of patients still showed improvements after several years

    • Menstruation often returns with return to normal weight

Treatments for anorexia nervosa7

Treatments for Anorexia Nervosa

  • Negatives of treatment:

    • Close to 20% of patients remain troubled for years

    • Even when it occurs, recovery is not always permanent

      • Relapses are usually triggered by stress

      • Many patients still express concerns about body shape and weight

Treatments for bulimia nervosa

Treatments for Bulimia Nervosa

  • Treatment programs are relatively new but have risen in popularity

  • Treatment is frequently offered in specialized eating disorder clinics

Treatments for bulimia nervosa1

Treatments for Bulimia Nervosa

  • The initial aims of treatment for bulimia nervosa are to:

    • Eliminate binge-purge patterns

    • Establish good eating habits

    • Eliminate the underlying cause of bulimic patterns

  • Programs emphasize education as much as therapy

Treatments for bulimia nervosa2

Treatments for Bulimia Nervosa

  • Several treatment strategies:

    • Individual insight therapy

      • The insight approach receiving the most attention is cognitive therapy, which helps clients recognize and change their maladaptive attitudes toward food, eating, weight, and shape

        • As many as 65% stop their binge-purge cycle

      • If cognitive therapy isn’t effective, interpersonal therapy (IPT), a treatment that seeks to improve interpersonal functioning, may be tried

      • A number of clinicians also suggest self-help groups or self-care manuals

Treatments for bulimia nervosa3

Treatments for Bulimia Nervosa

  • Several treatment strategies:

    • Behavioral therapy

      • Behavioral techniques are often included in treatment as a supplement to cognitive therapy

        • Diaries are often a useful component of treatment

      • Exposure and response prevention (ERP) is used to break the binge-purge cycle

Treatments for bulimia nervosa4

Treatments for Bulimia Nervosa

  • Several treatment strategies:

    • Antidepressant medications

      • During the past decade, antidepressant drugs have been used in bulimia treatment

        • Most common is fluoxetine (Prozac), an SSRI

        • Drugs help 25 to 40% of patients

      • Medications are best when used in combination with other forms of therapy

Treatments for bulimia nervosa5

Treatments for Bulimia Nervosa

  • Several treatment strategies:

    • Group therapy

      • Provides an opportunity for patients to express their thoughts, concerns, and experiences with one another

      • Helpful in as many as 75% of cases, especially when combined with individual insight therapy

Treatments for bulimia nervosa6

Treatments for Bulimia Nervosa

  • Left untreated, bulimia can last for years

  • Treatment provides immediate, significant improvement in about 40% of cases

    • An additional 40% show moderate improvement

  • Follow-up studies suggest that 10 years after treatment, about 90% of patients have fully or partially recovered

Treatments for bulimia nervosa7

Treatments for Bulimia Nervosa

  • Relapse can be a significant problem, even among those who respond successfully to treatment

    • Relapses are usually triggered by stress

    • Relapses are more likely among persons who:

      • Had a longer history of symptoms

      • Vomited frequently

      • Had histories of substance use

      • Have lingering interpersonal problems

  • Finally, treatment may also help improve overall psychological and social functioning
