  1. 1. Eating Disorders Chapter 9
  2. 2. Eating Disorders <ul><li>Although not historically true, current Western beauty standards equate thinness with health and beauty </li></ul><ul><ul><li>Thinness has become a national obsession </li></ul></ul><ul><li>There has been an increase in eating disorders in the past three decades </li></ul><ul><ul><li>The core issue is a morbid fear of weight gain </li></ul></ul><ul><li>Two main diagnoses: </li></ul><ul><ul><li>Anorexia nervosa </li></ul></ul><ul><ul><li>Bulimia nervosa </li></ul></ul>
  3. 4. Anorexia Nervosa <ul><li>There are two main subtypes: </li></ul><ul><ul><li>Restricting type </li></ul></ul><ul><ul><ul><li>Lose weight by cutting out sweets and fattening snacks, eventually restricting nearly all food </li></ul></ul></ul><ul><ul><ul><li>Show almost no variability in diet </li></ul></ul></ul><ul><ul><li>Binge-eating/purging type </li></ul></ul><ul><ul><ul><li>Lose weight by vomiting after meals, abusing laxatives or diuretics, or engaging in excessive exercise </li></ul></ul></ul><ul><ul><ul><li>Like those with bulimia nervosa, people with this subtype may engage in eating binges </li></ul></ul></ul>
  4. 5. Anorexia Nervosa <ul><li>About 90%–95% of cases occur in females </li></ul><ul><li>The peak age of onset is between 14 and 18 years </li></ul><ul><li>Between 0.5% and 2% of females in Western countries develop the disorder </li></ul><ul><ul><li>Many more display some symptoms </li></ul></ul><ul><li>Rates of anorexia nervosa are increasing in North America, Europe, and Japan </li></ul>
  5. 6. Anorexia Nervosa <ul><li>The “typical” case: </li></ul><ul><ul><li>A normal to slightly overweight female has been on a diet </li></ul></ul><ul><ul><li>Escalation toward anorexia nervosa may follow a stressful event </li></ul></ul><ul><ul><ul><li>Separation of parents </li></ul></ul></ul><ul><ul><ul><li>Move or life transition </li></ul></ul></ul><ul><ul><ul><li>Experience of personal failure </li></ul></ul></ul><ul><ul><li>Most victims recover </li></ul></ul><ul><ul><ul><li>However, about 2% to 6% become seriously ill and die as a result of medical complications or suicide </li></ul></ul></ul>
  6. 7. Anorexia Nervosa: The Clinical Picture <ul><li>The key goal for people with anorexia nervosa is becoming thin </li></ul><ul><ul><li>The driving motivation is fear: </li></ul></ul><ul><ul><ul><li>Of becoming obese </li></ul></ul></ul><ul><ul><ul><li>Of giving in to the desire to eat </li></ul></ul></ul><ul><ul><ul><li>Of losing control of body shape and weight </li></ul></ul></ul>
  7. 8. Anorexia Nervosa: The Clinical Picture <ul><li>Despite their dietary restrictions, people with anorexia nervosa are extremely preoccupied with food </li></ul><ul><ul><li>This includes thinking and reading about food and planning for meals </li></ul></ul><ul><ul><li>This relationship is not necessarily causal </li></ul></ul><ul><ul><ul><li>It may be the result of food deprivation, as evidenced by the famous 1940s “starvation study” with conscientious objectors </li></ul></ul></ul>
  8. 9. Anorexia Nervosa: The Clinical Picture <ul><li>Persons with anorexia nervosa also think in distorted ways: </li></ul><ul><ul><li>Usually have a low opinion of their body shape </li></ul></ul><ul><ul><li>Tend to overestimate their actual proportions </li></ul></ul><ul><ul><ul><li>Adjustable lens assessment technique </li></ul></ul></ul><ul><ul><li>Hold maladaptive attitudes and misperceptions </li></ul></ul><ul><ul><ul><li>“ I must be perfect in every way” </li></ul></ul></ul><ul><ul><ul><li>“ I will be a better person if I deprive myself” </li></ul></ul></ul><ul><ul><ul><li>“ I can avoid guilt by not eating” </li></ul></ul></ul>
  9. 10. Anorexia Nervosa: The Clinical Picture <ul><li>People with anorexia nervosa may also display certain psychological problems: </li></ul><ul><ul><li>Depression (usually mild) </li></ul></ul><ul><ul><li>Anxiety </li></ul></ul><ul><ul><li>Low self-esteem </li></ul></ul><ul><ul><li>Insomnia or other sleep disturbances </li></ul></ul><ul><ul><li>Substance abuse </li></ul></ul><ul><ul><li>Obsessive-compulsive patterns </li></ul></ul><ul><ul><li>Perfectionism </li></ul></ul>
  10. 11. Anorexia Nervosa: Medical Problems <ul><li>Caused by starvation: </li></ul><ul><ul><li>Amenorrhea </li></ul></ul><ul><ul><li>Low body temperature </li></ul></ul><ul><ul><li>Low blood pressure </li></ul></ul><ul><ul><li>Body swelling </li></ul></ul><ul><ul><li>Reduced bone density </li></ul></ul><ul><ul><li>Slow heart rate </li></ul></ul><ul><ul><li>Metabolic and electrolyte imbalances </li></ul></ul><ul><ul><li>Dry skin, brittle nails </li></ul></ul><ul><ul><li>Poor circulation </li></ul></ul><ul><ul><li>Lanugo </li></ul></ul>
  11. 12. Bulimia Nervosa <ul><li>Bulimia nervosa, also known as “binge-purge syndrome,” is characterized by binges: </li></ul><ul><ul><li>Bouts of uncontrolled overeating during a limited period of time </li></ul></ul><ul><ul><ul><li>Eat more than most people would/could eat in a similar period </li></ul></ul></ul>
  12. 13. Bulimia Nervosa <ul><li>The disorder is also characterized by inappropriate compensatory behaviors, such as: </li></ul><ul><ul><li>Vomiting </li></ul></ul><ul><ul><li>Misusing laxatives, diuretics, or enemas </li></ul></ul><ul><ul><li>Fasting </li></ul></ul><ul><ul><li>Exercising excessively </li></ul></ul>
  13. 14. Bulimia Nervosa <ul><li>Like anorexia nervosa, about 90%–95% of bulimia nervosa cases occur in females </li></ul><ul><li>The peak age of onset is between 15 and 21 years </li></ul><ul><li>Symptoms may last for several years with periodic letup </li></ul>
  14. 15. Bulimia Nervosa <ul><li>Patients are generally of normal weight </li></ul><ul><ul><li>Often experience marked weight fluctuations </li></ul></ul><ul><ul><li>Some may also qualify for a diagnosis of anorexia </li></ul></ul><ul><li>“ Binge-eating disorder” may be a related diagnosis </li></ul><ul><ul><li>Symptoms include a pattern of binge eating with NO compensatory behaviors (such as vomiting) </li></ul></ul><ul><ul><li>This pattern is not yet listed in the DSM </li></ul></ul>
  15. 16. Bulimia Nervosa <ul><li>Many teens and young adults go on eating binges or experiment with vomiting or laxatives after hearing about these behaviors from friends or the media </li></ul><ul><li>According to global studies, 25 to 50% of students report periodic binge-eating or self-induced vomiting </li></ul><ul><ul><li>Surveys suggests that as many as 5% develop the full syndrome </li></ul></ul>
  16. 17. Bulimia Nervosa: Binges <ul><li>People with bulimia nervosa may have between 1 and 30 binge episodes per week </li></ul><ul><li>Binges are often carried out in secret </li></ul><ul><ul><li>Binges involve eating massive amounts of food rapidly with little chewing </li></ul></ul><ul><ul><ul><li>Usually sweet foods with soft texture </li></ul></ul></ul><ul><li>Binge-eaters commonly consume more than 1000 calories (often more than 3000 calories) per binge episode </li></ul>
  17. 18. Bulimia Nervosa: Binges <ul><li>Binges are usually preceded by feelings of great tension </li></ul><ul><li>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 being discovered </li></ul>
  18. 19. Bulimia Nervosa: Compensatory Behaviors <ul><li>After a binge, people with bulimia nervosa try to compensate for and “undo” the caloric effects </li></ul><ul><li>The most common compensatory behavior is vomiting </li></ul><ul><ul><ul><li>Fails to prevent the absorption of half the calories consumed during a binge </li></ul></ul></ul><ul><ul><ul><li>Affects ability to feel satiated  greater hunger and bingeing </li></ul></ul></ul><ul><ul><li>Laxatives and diuretics </li></ul></ul><ul><ul><ul><li>Also almost completely fail to reduce the number of calories consumed </li></ul></ul></ul>
  19. 20. Bulimia Nervosa: Compensatory Behaviors <ul><li>Compensatory behaviors may temporarily relieve the negative feelings attached to binge eating </li></ul><ul><ul><li>Over time, however, a cycle develops in which purging  bingeing  purging… </li></ul></ul>
  20. 21. Bulimia Nervosa <ul><li>The “typical” case: </li></ul><ul><ul><li>A normal to slightly overweight female has been on an intense diet </li></ul></ul><ul><ul><li>Research suggests that even among normal subjects, bingeing often occurs after strict dieting </li></ul></ul><ul><ul><ul><li>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 </li></ul></ul></ul>
  21. 22. Bulimia Nervosa vs. Anorexia Nervosa <ul><li>Similarities: </li></ul><ul><ul><li>Onset after a period of dieting </li></ul></ul><ul><ul><li>Fear of becoming obese </li></ul></ul><ul><ul><li>Drive to become thin </li></ul></ul><ul><ul><li>Preoccupation with food, weight, appearance </li></ul></ul><ul><ul><li>Feelings of anxiety, depression, obsessiveness, perfectionism </li></ul></ul><ul><ul><li>Substance abuse </li></ul></ul><ul><ul><li>Distorted body perception </li></ul></ul><ul><ul><li>Disturbed attitudes toward eating </li></ul></ul>
  22. 23. Bulimia Nervosa vs. Anorexia Nervosa <ul><li>Differences: </li></ul><ul><ul><li>People with bulimia nervosa are more worried about pleasing others, being attractive to others, and having intimate relationships </li></ul></ul><ul><ul><li>People with bulimia nervosa tend to be more sexually experienced and active </li></ul></ul><ul><ul><li>People with bulimia nervosa are more likely to have histories of mood swings, low frustration tolerance, and poor coping </li></ul></ul>
  23. 24. Bulimia Nervosa vs. Anorexia Nervosa <ul><li>Differences: </li></ul><ul><ul><li>People with bulimia nervosa tend to be controlled by emotion – may change friendships easily </li></ul></ul><ul><ul><li>People with bulimia nervosa are more likely to display characteristics of a personality disorder </li></ul></ul><ul><ul><li>Different medical complications: </li></ul></ul><ul><ul><ul><li>Only half of women with bulimia nervosa experience amenorrhea vs. almost all women with anorexia nervosa </li></ul></ul></ul><ul><ul><ul><li>People with bulimia nervosa suffer damage caused by purging, especially from vomiting and laxatives </li></ul></ul></ul>
  24. 25. What Causes Eating Disorders? <ul><li>Most theorists use a multidimensional risk perspective: </li></ul><ul><ul><li>Several key factors place individuals at risk </li></ul></ul><ul><ul><li>More factors = greater risk </li></ul></ul><ul><ul><li>Leading factors: </li></ul></ul><ul><ul><ul><li>Psychological problems (ego, cognitive, and mood disturbances) </li></ul></ul></ul><ul><ul><ul><li>Biological factors </li></ul></ul></ul><ul><ul><ul><li>Sociocultural conditions (societal, family, and multicultural pressures) </li></ul></ul></ul>
  25. 26. What Causes Eating Disorders? Psychodynamic Factors: Ego Deficiencies <ul><li>Hilde Bruch developed a largely psychodynamic theory of eating disorders </li></ul><ul><li>Bruch argues that eating disorders are the result of disturbed mother–child interactions, which lead to serious ego deficiencies in the child and to severe cognitive disturbances </li></ul>
  26. 27. What Causes Eating Disorders? Psychodynamic Factors: Ego Deficiencies <ul><li>Bruch argues that parents may respond to their children either effectively or ineffectively </li></ul><ul><ul><li>Effective parents accurately attend to a child’s biological and emotional needs </li></ul></ul><ul><ul><li>Ineffective parents fail to attend to child’s internal needs; they feed when the child is anxious, comfort when the child is tired, etc. </li></ul></ul><ul><ul><ul><li>These children then turn to external guides and feel unable to establish independence </li></ul></ul></ul><ul><li>There is some empirical support for Bruch’s theory from clinical reports </li></ul>
  27. 28. What Causes Eating Disorders? Cognitive Factors <ul><li>Bruch’s theory also contains several cognitive factors </li></ul><ul><ul><li>According to cognitive theorists, such deficiencies contribute to a broad cognitive distortion that is at the center of disordered eating (e.g., disproportionate concerns about body shape and weight) </li></ul></ul>
  28. 29. What Causes Eating Disorders? Mood Disorders <ul><li>Many people with eating disorders, particularly those with bulimia nervosa, experience symptoms of depression </li></ul><ul><ul><li>Theorists believe mood disorders may “set the stage” for eating disorders </li></ul></ul>
  29. 30. What Causes Eating Disorders? Mood Disorders <ul><li>There is empirical support for the claim that mood disorders set the stage for eating disorders: </li></ul><ul><ul><li>Many more people with an eating disorder qualify for a clinical diagnosis of major depressive disorder than do people in the general population </li></ul></ul><ul><ul><li>Close relatives of those with eating disorders seem to have higher rates of mood disorders </li></ul></ul><ul><ul><li>People with eating disorders, especially those with bulimia nervosa, have serotonin abnormalities </li></ul></ul><ul><ul><li>People with eating disorders are helped by antidepressant medications </li></ul></ul>
  30. 31. What Causes Eating Disorders? Biological Factors <ul><li>Biological theorists suspect certain genes may leave some people particularly susceptible to eating disorders </li></ul><ul><ul><li>Consistent with this model: </li></ul></ul><ul><ul><ul><li>Relatives of people with eating disorders are up to 6 times more likely to develop the disorder themselves </li></ul></ul></ul><ul><ul><ul><li>Identical (MZ) twins with anorexia: 70% </li></ul></ul></ul><ul><ul><ul><li>Fraternal (DZ) twins with anorexia: 20% </li></ul></ul></ul><ul><ul><ul><li>Identical (MZ) twins with bulimia: 23% </li></ul></ul></ul><ul><ul><ul><li>Fraternal (DZ) twins with bulimia: 9% </li></ul></ul></ul><ul><ul><li>These findings may be related to low serotonin </li></ul></ul>
  31. 32. What Causes Eating Disorders? Biological Factors <ul><li>Other theorists believe that eating disorders may be related to dysfunction of the hypothalamus </li></ul><ul><ul><li>Researchers have identified two separate areas that control eating: </li></ul></ul><ul><ul><ul><li>Lateral hypothalamus (LH) </li></ul></ul></ul><ul><ul><ul><li>Ventromedial hypothalamus (VMH) </li></ul></ul></ul>
  32. 33. What Causes Eating Disorders? Biological Factors <ul><li>Some theorists believe that the LH and VMH are, in part, responsible for weight set point – a “weight thermostat” of sorts </li></ul><ul><ul><li>Set by genetic inheritance and early eating practices, this mechanism is responsible for keeping an individual at a particular weight level </li></ul></ul><ul><ul><ul><li>If weight falls below set point:  hunger,  metabolic rate  binges </li></ul></ul></ul><ul><ul><ul><li>If weight rises above set point:  hunger,  metabolic rate </li></ul></ul></ul><ul><ul><li>Dieters end up in a battle against themselves to lose weight </li></ul></ul>
  33. 34. What Causes Eating Disorders? Societal Pressures <ul><li>Many theorists believe that current Western standards of female attractiveness are partly responsible for the emergence of eating disorders </li></ul><ul><ul><li>Standards have changed throughout history toward a thinner ideal </li></ul></ul><ul><ul><ul><li>Miss America contestants have declined in weight by 0.28 lbs/yr; winners have declined by 0.37 lbs/yr </li></ul></ul></ul><ul><ul><ul><li>Playboy centerfolds have lower average weight, bust, and hip measurements than in the past </li></ul></ul></ul>
  34. 35. What Causes Eating Disorders? Societal Pressures <ul><li>Members of certain subcultures are at greater risk from these pressures: </li></ul><ul><ul><li>Models, actors, dancers, and certain athletes </li></ul></ul><ul><ul><ul><li>Of college athletes surveyed, 9% met full criteria for an eating disorder while another 50% had symptoms </li></ul></ul></ul><ul><ul><ul><li>20% of surveyed gymnasts appear to have an eating disorder </li></ul></ul></ul>
  35. 36. What Causes Eating Disorders? Societal Pressures <ul><li>Societal attitudes may explain economic differences seen in prevalence rates </li></ul><ul><ul><li>Historically, women of higher SES expressed more concern about thinness and dieting </li></ul></ul><ul><ul><ul><li>These women had higher rates of eating disorders than women of the lower socioeconomic classes </li></ul></ul></ul><ul><ul><li>Recently, dieting and preoccupation with food, along with rates of eating disorders, are increasing in all socioeconomic classes </li></ul></ul>
  36. 37. What Causes Eating Disorders? Societal Pressures <ul><li>The socially accepted prejudice against overweight people may also add to the “fear” and preoccupation about weight </li></ul>
  37. 38. What Causes Eating Disorders? Family Environment <ul><li>Families may play an important role in the development of eating disorders </li></ul><ul><ul><li>As many as half of the families of those with eating disorders have a long history of emphasizing thinness, physical appearance, and dieting </li></ul></ul><ul><ul><li>Mothers of those with eating disorders are more likely to be dieters and perfectionistic themselves </li></ul></ul>
  38. 39. What Causes Eating Disorders? Family Environment <ul><li>Abnormal interactions and forms of communication within a family may also set the stage for an eating disorder </li></ul><ul><ul><li>Influential family theorist Salvador Minuchin believes that “enmeshed family patterns” often lead to eating disorders </li></ul></ul><ul><ul><ul><li>These patterns include overinvolvement in, and overconcern about, family member’s lives </li></ul></ul></ul>
  39. 40. What Causes Eating Disorders? Multicultural Factors: Racial and Ethnic Differences <ul><li>A widely publicized 1995 study found that eating behaviors and attitudes of young African American women were more positive than those of young white American women </li></ul><ul><ul><li>Specifically, nearly 90% of the white American respondents were dissatisfied with their weight and body shape, compared to around 70% of the African American teens </li></ul></ul>
  40. 41. What Causes Eating Disorders? Multicultural Factors: Racial and Ethnic Differences <ul><li>Unfortunately, research conducted over the past decade suggests that body image concerns, dysfunctional eating patterns, and eating disorders are on the rise among young African American women as well as among women of other minority groups </li></ul><ul><ul><li>The shift appears to be partly related to acculturation </li></ul></ul>
  41. 42. What Causes Eating Disorders? Multicultural Factors: Racial and Ethnic Differences <ul><li>Other studies indicate that Hispanic American female adolescents now engage in disordered eating behaviors at rates about equal to those of white American women </li></ul><ul><li>Eating disorders also appear to be on the increase among Asian American women and young women in several Asian countries </li></ul>
  42. 43. What Causes Eating Disorders? Multicultural Factors: Gender Differences <ul><li>Males account for only 5% to 10% of all cases of eating disorders </li></ul><ul><li>The reasons for this striking difference are not entirely clear, but Western society’s double standard is, at the very least, one reason </li></ul><ul><li>A second reason may be the different methods of weight loss favored: </li></ul><ul><ul><li>Men are more likely to exercise </li></ul></ul><ul><ul><li>Women more often diet </li></ul></ul>
  43. 44. What Causes Eating Disorders? Multicultural Factors: Gender Differences <ul><li>It seems that some men develop eating disorders as linked to the requirements and pressures of a job or sport </li></ul><ul><ul><li>The highest rates of male eating disorders have been found among: </li></ul></ul><ul><ul><ul><li>Jockeys </li></ul></ul></ul><ul><ul><ul><li>Wrestlers </li></ul></ul></ul><ul><ul><ul><li>Distance runners </li></ul></ul></ul><ul><ul><ul><li>Body builders </li></ul></ul></ul><ul><ul><ul><li>Swimmers </li></ul></ul></ul>
  44. 45. What Causes Eating Disorders? Multicultural Factors: Gender Differences <ul><li>For other men, body image appears to be a key factor </li></ul><ul><li>Additionally, a new kind of eating disorder has emerged and is found almost exclusively among men – reverse anorexia nervosa or muscle dysmorphobia </li></ul>
  45. 46. How Are Eating Disorders Treated? <ul><li>Eating disorder treatments have two main goals: </li></ul><ul><ul><li>Correct dangerous eating patterns </li></ul></ul><ul><ul><li>Address broader psychological and situational factors that have led to, and are maintaining, the eating problem </li></ul></ul><ul><ul><ul><li>This often requires the participation of family and friends </li></ul></ul></ul>
  46. 47. Treatments for Anorexia Nervosa <ul><li>The initial aims of treatment for anorexia nervosa are to: </li></ul><ul><ul><li>Regain lost weight </li></ul></ul><ul><ul><li>Recover from malnourishment </li></ul></ul><ul><ul><li>Eat normally again </li></ul></ul>
  47. 48. Treatments for Anorexia Nervosa <ul><li>In the past, treatment took place in a hospital; it is now often offered in outpatient settings </li></ul><ul><li>In life-threatening cases, clinicians may need to force tube and intravenous feedings on the patient </li></ul><ul><ul><li>This may breed distrust in the patient and create a power struggle </li></ul></ul><ul><ul><li>In contrast, behavioral weight-restoration approaches have clinicians use rewards whenever patients eat properly or gain weight </li></ul></ul>
  48. 49. Treatments for Anorexia Nervosa <ul><li>The most popular weight-restoration technique has been the combination of supportive nursing care, nutritional counseling, and high-calorie diets </li></ul><ul><ul><li>Necessary weight gain is often achieved in 8 to 12 weeks </li></ul></ul>
  49. 50. Treatments for Anorexia Nervosa <ul><li>Researchers have found that people with anorexia nervosa must overcome their underlying psychological problems to achieve lasting improvement </li></ul><ul><li>Therapists use a combination of education, psychotherapy, and family approaches to achieve this broader goal; psychotropic drugs have been helpful in some cases </li></ul>
  50. 51. Treatments for Anorexia Nervosa <ul><li>In most treatment programs, a combination of behavioral and cognitive interventions are applied </li></ul><ul><ul><li>On the behavioral side, clients are required to monitor feelings, hunger levels, and food intake and the ties among those variables </li></ul></ul><ul><ul><li>On the cognitive sides, they are taught to identify their “core pathology” </li></ul></ul>
  51. 52. Treatments for Anorexia Nervosa <ul><li>Therapists help patients recognize their need for independence and control </li></ul><ul><li>Therapists help patients identify and trust their internal feelings </li></ul><ul><li>Therapists also help clients change their attitudes about eating and weight </li></ul><ul><ul><li>Using cognitive approaches, therapists correct disturbed cognitions and educate about body distortions </li></ul></ul>
  52. 53. Treatments for Anorexia Nervosa <ul><li>Another focus of treatment is changing family interactions </li></ul><ul><ul><li>Family therapy is important for anorexia nervosa treatment </li></ul></ul><ul><ul><li>The main issues are often separation and boundaries </li></ul></ul>
  53. 54. Treatments for Anorexia Nervosa <ul><li>The use of combined treatment approaches has greatly improved the outlook for people with anorexia nervosa </li></ul><ul><ul><li>But even with combined treatment, recovery is difficult </li></ul></ul><ul><li>The course and outcome of the disorder vary from person to person </li></ul>
  54. 55. Treatments for Anorexia Nervosa <ul><li>Positives of treatment: </li></ul><ul><ul><li>Weight gain is often quickly restored </li></ul></ul><ul><ul><ul><li>83% of patients still showed improvements after several years </li></ul></ul></ul><ul><ul><li>Menstruation often returns with return to normal weight </li></ul></ul><ul><ul><li>The death rate from anorexia nervosa seems to be falling </li></ul></ul>
  55. 56. Treatments for Anorexia Nervosa <ul><li>Negatives of treatment: </li></ul><ul><ul><li>Close to 20% of patients remain seriously troubled for years </li></ul></ul><ul><ul><li>Even when it occurs, recovery is not always permanent </li></ul></ul><ul><ul><ul><li>Anorexic behavior recurs in at least one-third of recovered patients, usually triggered by new stresses </li></ul></ul></ul><ul><ul><ul><li>Many patients still express concerns about their weight and appearance </li></ul></ul></ul><ul><ul><li>Lingering emotional problems are common </li></ul></ul>
  56. 57. Treatments for Bulimia Nervosa <ul><li>Treatment is frequently offered in eating disorder clinics </li></ul><ul><li>The immediate aims of treatment for bulimia nervosa are to: </li></ul><ul><ul><li>Eliminate binge-purge patterns </li></ul></ul><ul><ul><li>Establish good eating habits </li></ul></ul><ul><ul><li>Eliminate the underlying cause of bulimic patterns </li></ul></ul><ul><li>Programs emphasize education as much as therapy </li></ul>
  57. 58. Treatments for Bulimia Nervosa <ul><li>Cognitive-behavioral therapy is particularly helpful: </li></ul><ul><ul><li>Behavioral techniques </li></ul></ul><ul><ul><ul><li>Diaries are often a useful component of treatment </li></ul></ul></ul><ul><ul><ul><li>Exposure and response prevention (ERP) is used to break the binge-purge cycle </li></ul></ul></ul>
  58. 59. Treatments for Bulimia Nervosa <ul><li>Cognitive-behavioral therapy is particularly helpful: </li></ul><ul><ul><li>Cognitive techniques </li></ul></ul><ul><ul><ul><li>Help clients recognize and change their maladaptive attitudes toward food, eating, weight, and shape </li></ul></ul></ul><ul><ul><ul><li>Typically teach individuals to identify and challenge the negative thoughts that precede the urge to binge </li></ul></ul></ul>
  59. 60. Treatments for Bulimia Nervosa <ul><li>Other forms of psychotherapy </li></ul><ul><ul><li>If clients do not respond to cognitive-behavioral therapy, other approaches may be tried </li></ul></ul><ul><ul><li>A common alternative is interpersonal therapy (IPT) – a treatment that seeks to improve interpersonal functioning may be tried </li></ul></ul><ul><ul><li>Psychodynamic therapy has also been used </li></ul></ul>
  60. 61. Treatments for Bulimia Nervosa <ul><li>Other forms of psychotherapy </li></ul><ul><ul><li>Various forms of psychotherapy are often supplemented by family therapy and may be offered in either individual or group therapy format </li></ul></ul><ul><ul><ul><li>Group therapy provides an opportunity for patients to express their thoughts, concerns, and experiences with one another </li></ul></ul></ul><ul><ul><ul><li>Group therapy is helpful in as many as 75% of cases </li></ul></ul></ul>
  61. 62. Treatments for Bulimia Nervosa <ul><li>Antidepressant medications </li></ul><ul><ul><li>During the past decade, all groups of antidepressant drugs have been used in bulimia nervosa treatment </li></ul></ul><ul><ul><ul><li>Drugs help as many as 40% of patients </li></ul></ul></ul><ul><ul><li>Medications are best when used in combination with other forms of therapy, particularly cognitive-behavioral therapy </li></ul></ul>
  62. 63. Treatments for Bulimia Nervosa <ul><li>Left untreated, bulimia nervosa can last for years </li></ul><ul><li>Treatment provides immediate, significant improvement in about 40% of cases </li></ul><ul><ul><li>An additional 40% show moderate response </li></ul></ul><ul><li>Follow-up studies suggest that 10 years after treatment about 90% of patients have fully or partially recovered </li></ul>
  63. 64. Treatments for Bulimia Nervosa <ul><li>Relapse can be a significant problem, even among those who respond successfully to treatment </li></ul><ul><ul><li>Relapses are usually triggered by stress </li></ul></ul><ul><ul><li>Relapses are more likely among persons who: </li></ul></ul><ul><ul><ul><li>Had a longer history of symptoms </li></ul></ul></ul><ul><ul><ul><li>Vomited frequently </li></ul></ul></ul><ul><ul><ul><li>Had histories of substance use </li></ul></ul></ul><ul><ul><ul><li>Have lingering interpersonal problems </li></ul></ul></ul>
