Hile Bruch

A pioneer in the study and treatment of eating disorders and developed a largely psychodynamic theory. Believed that people with eating disorders perceive internal cues, including emotional cues, inaccurately. And, people with eating disorders rely excessively on the opinions, wishes, and views of others. They are more likely than other people to worry about how others view them, to seek approval, to be conforming, and to feel a lack of control over their lives. She argued that disturbed mother-child interactions lead to serious ego deficiencies in the child (including a poor sense of independence and control) and to severe perceptual disturbances that jointly help produce disordered eating. Parents may respond to their children either effectively or ineffectively. Children who receive such parenting may grow up confused and unaware of their own internal needs, not knowing for themselves when they are hungry or full and unable to identify their own emotions. Because they cannot rely on internal signals, these children turn instead to external guides, such as their parents. They seem to be "model children," but they fail to develop genuine self-reliance and "experience themselves as not being in control of their behavior, needs, and impulses, as not owning their own bodies". Adolescence increases their basic desire to establish independence, yet they feel unable to do so. To overcome their sense of helplessness, they seek excessive control over their body size and shape and over their eating habits.

They aspire to limit their eating, but are not as driven to thinness. Also, unlike the other eating disorders, it does not necessarily begin with efforts at extreme dieting. Nor are there large gender differences in the prevalence of it. Dx Checklist 1. Recurrent episodes. 2. Episodes include at least three of these features: • Unusually fast eating • Absence of hunger • Uncomfortable fullness • Secret eating due to sense of shame • Subsequent feelings of self-disgust, depression, or severe guilt. 3. Significant distress. 4. Episodes take place at least weekly over the course of 3 months. 5. Absence of excessive compensatory behaviors. Identified as a clinical syndrome.

Binging along with vomiting or other behaviors to compensate for the large number of calories ingested. Repeated episodes of uncontrollable overeating, or binges. A binge episode takes place over a limited period of time, often two hours, during which the person eats much more food than most people would eat during a similar time span. People with this disorder repeatedly perform inappropriate compensatory behaviors, such as forcing themselves to vomit; misusing laxatives, diuretics, or enemas; fasting or exercising excessively. Dx Checklist: 1. Repeated binge eating episodes. 2. Repeated performance of ill-advised compensatory behaviors (e.g., forced vomiting) to prevent weight gain. 3. Symptoms take place at least weekly for a period of 3 months. 4. Inappropriate influence of weight and shape on appraisal of oneself.

Purposely maintaining a significantly low body weight, intense fears of becoming overweight, has a distorted view of weight and shape, and is excessively influenced by weight and shape in self-evaluations. Significantly low body weight with an intense fear of gaining weight along or using various methods to prevent weight gain. Dx Checklist: 1. Individual purposely takes in too little nourishment, resulting in body weight that is very low and below that of other people of similar age and gender. 2.

What causes eating disorders?

From the multidimensional risk perspective, there are several key factors place individuals at risk. The more factors one has, the greater likelihood of developing an eating disorder. Leading Factors: -Psychological problems (operent conditioning, perfectionism, neuroticism). -Biological factors -Sociocultural conditions (societal, family, and multicultural pressures.

What are the immediate goals of treatment programs for bulimia nervosa?

Helping clients to eliminate their binge-purge patterns and establish good eating habits and the more general goal of eliminating the underlying causes of bulimic patterns.

How do those with anorexia nervosa think?

In distorted ways. They usually have a low opinion of their body shape, and consider themselves unattractive. They are likely to overestimate their actual proportions; the estimates of those with anorexia nervosa are particularly high. It also takes the form of certain maladaptive attitudes and misperceptions. Sufferers tend to hold such beliefs as "I must be perfect in every way"; "I will become a better person if I deprive myself "; and "I can avoid guilt by not eating."

Is serotonin linked to eating disorders?

It is possible. Several research teams have found a link between eating disorders and the genes responsible for the production of this neurotransmitter. Others have measured low neurotransmitter activity in many people with eating disorders. It plays a role in depression and obsessive-compulsive disorder—problems that often accompany eating disorders—so it is possible that low serotonin activity has more to do with those other disorders than with the eating disorders per se. On the other hand, perhaps low activity contributes directly to eating disorders—for example, by causing the body to crave and binge on high-carbohydrate foods.

What sports have the highest rates of eating disorders for males?

Jockeys, wrestlers, distance runners, body builders, swimmers.

They typically feel shame about their bodies, and many have a history of depression, anxiety, and self-destructive compulsive behavior. About one-third of them also engage in related dysfunctional behaviors such as binge eating.

What is the core issue of someone with an eating disorder?

Morbid fear of gaining weight.

How does cognitive-behavioural therapy assist those with eating disorders?

On the behavioral side, clients monitors feelings, hunger levels, and food intake and the ties among those variables. On the cognitive side, the therapist helps the client change attitudes about eating and weight.

What does repeated vomiting affect?

The LH and certain other brain areas are activated and seek to restore the lost weight by producing hunger and lowering the body's metabolic rate.

What happens when a person's weight rises above their set point?

The VMH and certain other brain areas are activated, and they try to remove the excess weight by reducing hunger and increasing the body's metabolic rate.

Amenorrhea

The absence of menstrual cycles.

Binging

The person eats massive amounts of food very rapidly, with minimal chewing—usually sweet, high-calorie foods with a soft texture, such as ice cream, cookies, doughnuts, and sandwiches. The food is hardly tasted or thought about. Eaters consume an average of 3400 calories during an episode. Some individuals consume as many as 10,000 calories. Usually preceded by feelings of great tension. The person feels irritable, "unreal," and powerless to control an overwhelming need to eat "forbidden" foods. During, the person feels unable to stop eating. Although the act itself may be experienced as pleasurable in the sense that it relieves the unbearable tension. Followed by feelings of extreme self-blame, shame, guilt, and depression, as well as fears of gaining weight and being discovered.

Acculturation

The process of adopting the cultural traits or social patterns of another group.

Metabolic Rate

The rate at which the body expends energy.

Weight Set Point Theory

The theory that when people diet and fall to a weight below their weight set point, their brain starts trying to restore the lost weight. Hypothalamic and related brain activity produce a preoccupation with food and a desire to binge. They also trigger bodily changes that make it harder to lose weight and easier to gain weight, however little is eaten. Once the brain and body begin conspiring to raise weight in this way, dieters actually enter into a battle against themselves. Some people apparently manage to shut down the inner "thermostat" and control their eating almost completely. These people move toward restricting-type anorexia nervosa. For others, the battle spirals toward a binge-purge or binge-only pattern.

Interpersonal Psychotherapy

The treatment that is used to help improve interpersonal functioning.

What kinds of cognitive interventions are used to treat patients with anorexia nervosa?

They are taught to identify their "core pathology"—the deep-seated belief that they are judged by their shape and weight and by their ability to control these physical characteristics. The clients may also be taught alternative ways of coping with stress and of solving problems.

What are some cognitive techniques therapists use with bulimia nervosa clients?

They help clients with bulimia nervosa recognize and change their maladaptive attitudes toward food, eating, weight, and shape. The therapists typically teach the clients to identify and challenge the negative thoughts that regularly precede their urge to binge—"I have no self-control"; "I might as well give up"; "I look fat". They may also guide clients to recognize, question, and eventually change their perfectionistic standards, sense of helplessness, and low self-concept

What are some behavioral techniques therapists use with bulimia nervosa clients?

To keep diaries of their eating behavior, changes in sensations of hunger and fullness, and the ebb and flow of other feelings. This helps the clients to observe their eating patterns more objectively and recognize the emotions and situations that trigger their desire to binge. They may also use exposure and response prevention to break the binge-purge cycle. The therapists require clients to eat particular kinds and amounts of food and then prevent them from vomiting to show that eating can be a harmless and even constructive activity that needs no undoing. Studies find that this treatment often helps reduce eating-related anxieties, bingeing, and vomiting.

What method do clinicians sometimes use in life-threatening cases of anorexia nervosa?

Tube and intravenous feedings., although it might cause the patient to distrust the clinician.

When do bulimic patterns typically begin?

Typically during or after a period of intense dieting, often one that has been successful and earned praise from family members and friends.

The escalation may follow a stressful event such as separation of parents, a move away from home, or an experience of personal failure. Although most people with the disorder recover, between 2 and 6 percent of them become so seriously ill that they die, usually from medical problems brought about by starvation, or from suicide.

What must people with anorexia nervosa overcome before they can have lasting improvement?

Underlying psychological problems.

After a binge, people with bulimia nervosa try to compensate for and try to do what?

Undo the caloric effect.

Do families play a role in the development and maintenance of eating disorders?

Yes. Research suggests that as many as half of the families of people with anorexia nervosa or bulimia nervosa have a long history of emphasizing thinness, physical appearance, and dieting. The mothers in these families are more likely to diet themselves and to be generally perfectionistic than are the mothers in other families. Abnormal interactions and forms of communication within a family may also set the stage. Families are often dysfunctional to begin with and that the eating disorder of one member is a reflection of the larger problem.

Does social media affect body dissatisfaction?

Yes. The more time teenage girls spend on social media, the higher their body dissatisfaction. 86% of teens say that social network sites hurt their body confidence.

Does climate affect the statistics regarding the number of people who suffer from eating disorders?

Yes. Women who live in warmer climates (where more revealing clothing is worn) have lower weight, engage in more binge eating and purging, and have more body image concerns than women who live in cooler climates.
