There is no single cause for the development of an eating disorder. Most resources indicate that numerous factors such as, genetics, hormonal abnormalities, cultural pressures, and negative family history or early childhood trauma can cause an eating disorder. Eating disorders have the highest mortality rate of any mental illness. If you think, or know you are experiencing symptoms of an eating disorder you are not alone. It is estimated that nearly 8 million Americans are suffering from an eating disorder (7 million women and 1 million men).
What are the different types of eating disorders?
Anorexia nervosa
Anorexia nervosa is characterized by:
A. Restriction of energy intake relative to requirements, leading to a significantly low body weight in the context of age, sex, developmental trajectory, and physical health. Significantly low weight is defined as a weight that is less than minimally normal or, for children and adolescents, less than that minimally expected.
B. Intense fear of gaining weight or of becoming fat, or persistent behavior that interferes with weight gain, even though at a significantly low weight.
C. Disturabance in the way in which one's body wieght or shape is experienced, undue infuluence of body weight or shape on self-evaluation, or persistent lack of recognition of the seriousness of the currrent low body weight.
Many people with anorexia nervosa see themselves as overweight, even when they are clearly underweight. Eating, food, and weight control become obsessions. People with anorexia nervosa typically weigh themselves repeatedly, portion food carefully, and eat very small quantities of only certain foods. Some people with anorexia nervosa may also engage in binge-eating followed by extreme dieting, excessive exercise, self-induced vomiting, and/or misuse of laxatives, diuretics, or enemas.
Some who have anorexia nervosa recover with treatment after only one episode. Others get well but have relapses. Still others have a more chronic, or long-lasting, form of anorexia nervosa, in which their health declines as they battle the illness.
Other symptoms may develop over time, including:
· Thinning of the bones (osteopenia or osteoporosis)
· Brittle hair and nails
· Dry and yellowish skin
· Growth of fine hair all over the body (lanugo)
· Mild anemia and muscle wasting and weakness
· Severe constipation
· Low blood pressure, slowed breathing and pulse
· Damage to the structure and function of the heart
· Brain damage
· Multi-organ failure
· Drop in internal body temperature, causing a person to feel cold all the time
· Lethargy, sluggishness, or feeling tired all the time
· Infertility.
Bulimia nervosa
Bulimia nervosa is characterized by recurrent and frequent episodes of eating unusually large amounts of food and feeling a lack of control over these episodes. This binge-eating is followed by behavior that compensates for the overeating such as forced vomiting, excessive use of laxatives or diuretics, fasting, excessive exercise, or a combination of these behaviors.
Unlike anorexia nervosa, people with bulimia nervosa usually maintain what is considered a healthy or normal weight, while some are slightly overweight. But like people with anorexia nervosa, they often fear gaining weight, want desperately to lose weight, and are intensely unhappy with their body size and shape. Usually, bulimic behavior is done secretly because it is often accompanied by feelings of disgust or shame. The binge-eating and purging cycle happens anywhere from several times a week to many times a day.
Other symptoms include:
· Chronically inflamed and sore throat
· Swollen salivary glands in the neck and jaw area
· Worn tooth enamel, increasingly sensitive and decaying teeth as a result of exposure to stomach acid
· Acid reflux disorder and other gastrointestinal problems
· Intestinal distress and irritation from laxative abuse
· Severe dehydration from purging of fluids
· Electrolyte imbalance (too low or too high levels of sodium, calcium, potassium and other minerals), which can lead to heart attack.
Binge-eating disorder
With binge-eating disorder a person loses control over his or her eating. Unlike bulimia nervosa, periods of binge-eating are not followed by purging, excessive exercise, or fasting. As a result, people with binge-eating disorder often are over-weight or obese. People with binge-eating disorder who are obese are at higher risk for developing cardiovascular disease and high blood pressure. They also experience guilt, shame, and distress about their binge-eating, which can lead to more binge-eating.
How are eating disorders treated?
Adequate nutrition, reducing excessive exercise, and eliminating purging behaviors are the foundations of treatment. Specific forms of psychotherapy, or talk therapy, and medication are effective for many eating disorders. However, in more chronic cases, specific treatments have not yet been identified. Treatment plans often are tailored to individual needs and may include one or more of the following:
· Individual, group, and/or family psychotherapy
· Medical care and monitoring
· Nutritional counseling
· Medications
· Yoga Therapy (for trauma and/or anxiety)
Some patients may also need to be hospitalized to treat problems caused by mal-nutrition or to ensure they eat enough if they are very underweight.
Treating anorexia nervosa
Treating anorexia nervosa involves three components:
· Restoring the person to a healthy weight
· Treating the psychological issues related to the eating disorder
· Reducing or eliminating behaviors or thoughts that lead to insufficient eating and preventing relapse.
Different forms of psychotherapy, including individual, group, and family-based, can help address the psychological reasons for the illness. In a therapy called the Maudsley approach, parents of adolescents with anorexia nervosa assume responsibility for feeding their child. This approach appears to be very effective in helping people gain weight and improve eating habits and moods. Shown to be effective in case studies and clinical trials, the Maudsley approach is discussed in some guidelines and studies for treating eating disorders in younger, non-chronic patients.
Other research has found that a combined approach of medical attention and supportive psychotherapy designed specifically for anorexia nervosa patients is more effective than psychotherapy alone. The effectiveness of a treatment depends on the person involved and his or her situation. Unfortunately, no specific psychotherapy appears to be consistently effective for treating adults with anorexia nervosa. However, research into new treatment and prevention approaches is showing some promise. One study suggests that an online intervention program may prevent some at-risk women from developing an eating disorder. Also, specialized treatment of anorexia nervosa may help reduce the risk of death.
Treating bulimia nervosa
As with anorexia nervosa, treatment for bulimia nervosa often involves a combination of options and depends upon the needs of the individual. To reduce or eliminate binge-eating and purging behaviors, a patient may undergo nutritional counseling and psychotherapy, especially cognitive behavioral therapy (CBT), or be prescribed medication. CBT helps a person focus on his or her current problems and how to solve them. The therapist helps the patient learn how to identify distorted or unhelpful thinking patterns, recognize, and change inaccurate beliefs, relate to others in more positive ways, and change behaviors accordingly.
CBT that is tailored to treat bulimia nervosa is effective in changing binge-eating and purging behaviors and eating attitudes. Therapy may be individual or group-based.
Treating binge-eating disorder
Treatment options for binge-eating disorder are similar to those used to treat bulimia nervosa. Psychotherapy, especially CBT that is tailored to the individual, has been shown to be effective. Again, this type of therapy can be offered in an individual or group environment.
