Eating disorders

Healthy people need to regularly consume a rich variety of foods that are sufficient for energy

needs, cellular growth and repair, and maintenance of sufficient weight. Most people normally eat 1,500

2,500 calories each day.

Eating is a normal response to hunger should cease when the person attains satiety (comfortable

fullness).

People develop problems related to normal food consumption and satiety which is called eating

disorders.

Eating disorders are most common in females (85%-90%) than males (10%-15%) but recent studies

find that the incidence of eating disorders in males is increasing by incidence ratio of 2women :1 men for

anorexia nervosa and the ratio of 3 women : 1 men for bulimia nervosa, and seems to appear at a later agethan in females.

Eating disorders are those in which eating:

1- Below or above a persons caloric needs to maintain a healthy weight.

2- Accompanied by anxiety and guilt.

3- Occurs without hunger or fails to produce satiety.

4- Results in physiologic imbalances or medical complications.

The most serious eating disorders are anorexia nervosa and bulimia nervosa.

Anorexia nervosa is a life threatening condition of disturbed body image, emaciation, intense fear of

becoming obese.

Bulimia nervosa is a recurrent pattern of uncontrollable consumption of large amount of food (binge

eating) followed by attempts to eliminate the body of the excess calories (purging).

Etiology and precipitating factors:

Most experts agree that eating disorders have multifactorial causes with significant variance among

individuals developing from complex interaction of individual, family, sociocultural elements.

1- Biologic factors: increase serotonin levels.

2- Cognitive and behavioral factors: environmental contingencies.

3- Psychodynamic factors: modern psychoanalytic theorists have stressed the role of sexuality in

anorexia nervosa, and some researchers have suggested that anorexia involves a regression to a

pre-pubertal state, and another theory has described anorexia nervosa as an obsession with weight

stemming from a fear of being out of control because of the lack of a well-defined self.


5/17

4- Family factors: emotional restraint, enmeshed relationships, rigid organization in the family, tight

control of child behavior by parents, avoidance of conflict, and odd eating habits and emphasis on

appearance and weight by other family members especially mothers and sisters.

5- Sociocultural factors: the increasingly and unrealistically thin body ideal for women, almost a

cultural thinness, and the relational orientation of women, which creates a vulnerability to the

opinions of others particularly during adolescence.

When working with clients and populations who may be at risk for eating disorders, nurses should

remember to discuss the 3Cs:

1- Communication: how to recognize and express feelings.

2- Conflict resolution: how to express needs when they arent being met.

3- Coping: what to do when the client cant directly solve a problem.

Implications and prognosis:

Peoples with eating disorders rarely seek help, typically arent motivated to change, and often

leave treatment.

Bulimia nervosa has higher rate of recovery than does anorexia nervosa.

In a 10 years follow-up study of clients with bulimia approximately 30% continued to engage in

binge eating or purging behaviors.

Care management is complex and frequently lengthy because these clients may resist treatment

because of denial is typically strong.

Nurses, physicians, psychotherapists, social workers, dietitians, occupational therapists collaborate

to form a treatment plan.

Anorexia nervosa:

A life threatening condition characterized by a refusal to maintain body weight at or above a

minimally normal weight for age and height, an intense few of becoming fat, a distorted body image, and

amenorrhea or irregular menstrual cycles in women and low testosterone hormone levels in men.

Anorexia is less common than bulimia, 85% of cases developing between the ages of 13 and 20 years,

onset varies from preadolescence to early adulthood, these ages correspond with transitional stages in

people lives, and the disease have the mortality rate of 5-20%.

The anorectics suppress their appetite in an effort to remain thin or get thinner but they dont lose their

appetite, and they have ritualistic eating patterns and compulsive behaviors, often feel hopeless, helpless,

and depressed.

The anorexia affects menstruation by causing amenorrhea, irregular and spotty menstruation, and

affects cardiac muscles (atrophy) and decrease cardiac output.

The course of anorexia varies from:

1- A single episode with weight and psychological recovery.


6/17

2- Nutritional rehabilitation with relapses.

3- An unremitting course resulting in death.

Patients with anorexia nervosa are into two types:

1-Restrictors:

They are young people in the normal or slightly above normal weight for height.

This group views losing weight as more probable if they simply eat less and avoid social

situations in which they are expected to eat. Withdraw to their rooms and avoid family and

friends.

They could be competitive, compulsive, and obsessive about their activities, highly anxious and

unable to relax, become hyperactive.

2-Vomiters- purgers:

They are more often fluctuating and overweight before the eating disorder begins.

This group use dangerous methods of weight reduction, such as induction of vomiting or

excessive use of laxatives or diuretics.

The amount of food isnt excessive as it with bulimics,

These patients complain of dental problems, substance abuse, and open family conflict than

restricting anorectics.

Signs and symptoms of anorexia nervosa:

Psychosocial: extreme fear of gaining weight, poor social adjustment, odd food habits,

hyperactivity, mood and\or sleep disturbances, obsessive compulsive behaviors, perfectionist,

introverted, denies feeling of sadness or anger and will often appear pleasant and complaint,

families often have rigid rules, and have high expectations for their members.

Physiologic and endocrine symptoms: emaciated physical appearance, changes in cardiac status

(bradycardia, HTN, dysrhythmia), dry yellowish skin, amenorrhea, infertility, hair loss, possible

presence of lanugo, decreased metabolic rate, chronic constipation, fatigue and lake of energy,

insomnia, loss of bone mass, osteoporosis, enlarged salivary glands, decayed tooth, dehydration,

edema, laboratory abnormalities and medical complications.

DSM-IV-TR diagnostic criteria for anorexia nervosa:

1- Refusal to maintain body weight at or above a minimum normal weight for age and height.

2- Intensive fear of gaining weight or becoming fat, although significantly underweight.

3- Disturbance in the way in which ones body weight or shape is experienced, overvaluing of low

weight or weight loss.

4- In women and female adolescents, the absence of at least three consecutive menstrual cycles.


7/17

Restricting type: during an episode of anorexia nervosa, individuals dont engage in recurrent

episodes of binge eating or purging.

Binge eating or purging type: during an episode of anorexia nervosa, individuals engage in

recurrent episodes of binge eating or purging.

Favorable prognostic indicators:

1- Earlier age at onset.

2- Return of menses.

3- Good pre-morbid school\work history.

Negative prognostic indicators:

1- Recurrent illness.

2- Multiple hospitalizations.

3- Male.

4- Family pathology.

5- Pre-morbid personality difficulties and poor social adjustment in childhood.

Bulimia nervosa:

Is a condition of uncontrolled rapid ingestion of large quantities of food followed by self-induced

vomiting, obsessive exercise, use of laxatives and diuretics, or all of these behaviors. Its maybe occurs

alone or in conjunction with the food restriction of anorexia.

They may consume an incredible number of calories (an average of 39415 per binge) then in a short

period induce vomiting, and perhaps repeat this behavior several times a day.

Bulimia nervosa frequently exist with major depression, substance abuse, personality disorders,

primarily those with impulsive traits.

Clients with bulimia may develop:

Dental caries from the frequent contact of tooth enamel with food and acidic gastric fluids.

ECG changes.

Parotid gland enlargement.

Esophagitis.

Gastric dilation.

Menstrual irregularity.


8/17

Electrolyte imbalance.

DSM-IV-TR diagnostic criteria for bulimia nervosa:

1. Recurrent episodes of binge eating in a short time period, with intake much greater than average.

2. A feeling of lack of control over eating behaviors during eating binges.

3. Recurrent inappropriate compensatory behavior in order to prevent weight gain, such as induced

vomiting, use of laxatives, enemas, or diuretics, strict dieting or fasting, vigorous exercise, or

taking diet pills.

4. Binge eating and inappropriate compensatory behaviors both occurring, on average, at least twice a

week for 3 months.

5. Self-evaluation unduly influenced by body shape and weight.

Purging type: regularly engages in self-induced vomiting or the use of laxatives, diuretics, or

enemas.

Non-purging type: regularly uses strict diet, fasting, or vigorous exercise, but doesnt regularly

engage in purging.

Treatment:

Clinical and dialectical-pharmacologic behavioral therapies (CBT) for those with bulimia appear to

have good response in conjunction with interpersonal psychotherapy and pharmacotherapy.

Pharmacologic: 1- fluoxetine 60 mg\day for 6-18 weeks reduces the symptoms of binging and

purging. 2- tricyclic antidepressant is also found useful in treating bulimia nervosa.

Comparing between anorexia nervosa and bulimia nervosa:

Shared features:

Restriction of intake at times, especially anorectics.

Bingeing overeating at times, especially bulimics.

Purging through vomiting, laxatives, or diuretics.

Over exercise.

Extreme concern about appearance.


9/17

Perfectionist traits-dissatisfaction with appearance and performance in aspects of life such as work

or school.

Belief that their worth is based solely on appearance.

Discomfort in social settings, especially with the opposite gender.

Misperception of their size, shape, and level of fat.

Low-self esteem.

Differentiation of behaviors:

Anorexia Bulimia

Early onset later onset

Very low weight more normal weight

Amenorrhea for some patients menstrual irregularities but not amenorrhea

Hormonal imbalance fluid and electrolyte imbalance

Constipation if not using laxatives GI problems related to bingeing and purging

Binge eating disorder:

Is one of the most challenging current epidemics in western countries involves overweight and obesity,conditions that result from the regular overconsumption of calories and sedentary life styles.

BED shares many criteria of bulimia nervosa (lack of control over intake, patient distress, and guilt

over bingeing) but without the regular compensation for excess intake through purging, laxatives, fasting,

or over exercise.

Patients with BED tends to be overweight to a moderate or greater degree and their weight tends to

fluctuate more compared with those with anorexia or bulimia.

As with bulimia, the onset of this disorder tends to be later than anorexia, generally beginning in late

adolescence to early adulthood, but currently isnt considered a psychiatric disorder in the DSM-IV-TR

because of the rapidly growing numbers of obese people of all ages.

Many researchers view obesity as the result of compulsive eating behavior and it certainly associated

with morbidity.

Characteristics of BED include:

1- Recurrent eating binges.

2- Guilt, shame, and disquiet about bingeing.

3- Marked psychological distress.


10/17

Males eating disorders:

The incidence of eating disorders among males is currently 10%-15% of the eating-disordered

population. And the diagnosis, etiologies, and treatment is similar to eating disorders among females, but

there appear to be differences in onset, presentation, and assessment.

Males seem to have more difficulty than females in expressing their feelings so the therapeuticrelationship could be instrumental in the recovery of them.

Males are more likely than females with eating disorders to have a history of obesity before the onset

of symptoms of an eating disorder and to have a later and higher initial BMI before becoming eating-

disordered.

Males also tend to feel less guilt than in females about episodes of bingeing and purging. And dieting

or bingeing is more often related to a desire to build a lean body for participation in sports.

There is three areas need particular focus with males for treatment of eating disorder:

1- The excessive attention that adolescent boys can place on attaining a masculine physique and its

effect on their body image.

2- Dietary habits to promote health fitness, and muscle mass without using disordered eating patterns.

3- The expression of feelings and the exploration of any underlying sexual identity concerns.

Manifestations of cognitive distortions in clients with eating disorders:

Distortion Explanation Example

Catastrophizing\

magnification

Giving an event or its consequences

more merit than is realistic

These jeans feel tight today. I know

everyone can tell that Ive gained 3 lb.

Dichotomous

thinking

Reasoning by extremes, seeing

everything as black or white

If Im thin, I must be fat;

Ive already eaten two slices of pizza and

wrecked my diet. I might as well eat the

whole thing.

Emotional reasoning Relying on emotions to determine

reality

I know Im fat because I feel fat.

Overgeneralization Basing beliefs on one or a few, not

necessarily related, considerations.

I dont have a boyfriend. It must be

because Im fat.

Liz is so thin and has the perfect life. I

should lose weight so my life can be better

personalization Over interpreting an event as

having personal significance.

Dad made a face when I grabbed a piece

of candy from the jar, he must think Im

overweight.

Selective abstraction Focusing on only some information

while choosing to ignore other

information.

Ive lost 10 lb. but I still cant fit into a

size 8 Im a failure.

Psychotherapeutic management:

The psychotherapeutic management of each disorder will vary, depending on the period of treatment

being considered and whether the focus is on short or long term treatment.


11/17

Management of anorexia is geared toward three primary objectives:

1- Increasing weight to at least 90% of the average body weight for the patients height.

2- Helping the patient to establish appropriate eating behavior.

3- Increasing self-esteem, so the patient doesnt need to attain the perfection that they believe

thinness provides.

For bulimics, the objectives are similar but rather than the need for weight increase, are more likely to

focus on stabilizing weight without purging, because bulimics are more likely to be of normal weight. And

pharmacotherapy is used as an adjunct to psychotherapy for bulimics when indicated.

A stepped care approach might be useful, in which patient first participate in a simple treatment such

as guided self-help or a psycho educational group with their families and if they dont respond are referred

for cognitive-behavior therapy, and if dont improve will be referred for a more intensive form of

treatment, such as interpersonal psychotherapy, partial or full hospitalization, and possibly antidepressants

medication.

Cognitive-behavioral therapy has the greatest research support, although limited evidence exist

suggesting that interpersonal psychotherapy might have similar effectiveness.

Effective therapeutic modalities for people suffering from eating disorders:

1- Behavioral therapy: using apparent conditioning paradigm, effective in inducing short-term

weight gain.

2- Cognitive therapy: examining underlying assumptions, modifying basic assumptions,

reinterpreting body image misperceptions, help client to challenge the validating of distortedbeliefs and perceptions that are perpetuating their illness.

3- Family therapy: interventions focus on fostering open, healthy interaction patterns among

members. Behavior family systems therapy (BFST) is an approach that blends behavior

modification, cognitive therapy, and family therapy. It relies on empirically tested behavioral and

cognitive techniques. And consist of four stages:

Assessment.

Control rationale.

Weight gain.

Weight maintenance.

4- Individual psychotherapy: successful psychotherapy needs to be highly interactive, explore

relevant issues, educate, negotiate, challenge assumptions underlying anorectic behavior, and

encourage the client directly and openly.


12/17

Nurse-patient relationship:

Specific therapeutic communication techniques helpful for eating-disordered patients include the

following:

1- Convey warmth and sincerity.

2- Listen empathically.

3- Be honest.

4- Set appropriate behavioral limits.

5- Assist patient in identifying their positive qualities.

6- Collaborate with patients.

7- Teach patients about their disorders.

8- Determine the anorectics ability to be weighted in the early stages of treatment.

9- Initiate a behavior modification program with patient input that rewards weight gain or lack of

purging with meaningful privileges or rewards.

10- Model and teach appropriate social skills.

11- Help patient identify and express bodily sensations and feelings related to their disorders.

12- Identify non-weight-related interests of the patient.

Psychopharmacology:

Currently, no psychopharmacologic agent is approved specifically for anorexia nervosa; medication

management of anxiety, depression, somatic disturbances, or other co-morbid conditions is appropriate

and might assist in treatment of the patient anorexia.

Generally, psychotherapy is recommended before a trial of an antidepressant, antidepressants are

considered when the patient has failed to respond adequately to psychotherapy alone or when there is co-

morbidity with severe clinical depression.

Low dose imipramine in conjunction with dietary counseling and psychological support is also

associated with decreases in binge eating and weight loss.

Anxiolytics: to decrease anxiety that fuels a bulimics bingeing and purging.

Antidepressants: to reduce bingeing, purging, and depression in bulimic patients.

Atypical antipsychotic olanzepine (zyprexa): has been tried to promote weight gain.

Antihistamine: effective in emaciated anorectic in decreasing depression.

Lithium: to improve mood.


13/17

Milieu management:

1- Provide an orientation to the sitting to prepare the patient for inpatient or outpatient treatment so

that fears will be reduced.

2- Provide a warm, nurturing atmosphere.

3- Closely observe patients.

4- Encourage the patient to approach a team member if feeling the need to purge.

5- Involve the patients family in treatment when appropriate.

6- Respond with consistency.

and individual psychotherapy for patients with a qualified therapist.

Nursing process:

Assessment:

1- Health history: nutrition, elimination, reproduction and hormones, activity and rest,psychosocial.

2- Physical examination: body weight, skin, nutritional state examination, cardiac examination,

GI examination.

3- Laboratory testing: electrolyte abnormalities and cardiac dysfunction.

4- Diagnostic procedure: ECG, endoscopy.

Nursing diagnosis:

1- Imbalanced nutrition less than body requirements related to refusal to ingest or retain ingested

food, physical excess of caloric intake.

2- Disturbed thought process related to intellectualization, obsessions, overgeneralization and

malnutrition.

3- Disturbed body image related to unresolved psychosocial conflicts.

4- Chronic low self-esteem related to unrealistic expectations from self or others, lack of positive

feedback, striving to please others to gain acceptance.

5- Powerlessness related to belief that ones actions will not result in desired outcome.


14/17

6- Ineffective coping related to unmet developmental tasks (trust, autonomy), dysfunctional

family system.

7- Interrupted family process related to ineffective communication patterns, denial of problems

and conflict, unresolved issues of control, inability to manage conflict.

intake of the patient.

6- Encourage use of therapies or support groups to attain healthy weight and prevent relapse.

7- Promote patient decision making concerning issues other than food.

family, sociocultural, and physiologic factors.

2- Clients with eating disorders exhibit disturbances in many or all of the functional health patterns.

3- Treatment of clients with eating disorders occurs in community-based and inpatient settings and is

a complex and often lengthy process.
