Which of the following are typical characteristics of a person with anorexia nervosa in the United States?
What is Anorexia Nervosa?Anorexia nervosa is an eating disorder in which a person intentionally limits the intake of food or beverage because of a strong drive for thinness and an intense fear of gaining weight. This can happen even if a person is already thin. The perception of body weight and shape is distorted and has an unduly strong influence on a person’s self-concept. The resulting weight loss and nutritional imbalance can lead to serious complications, including death. Show
Obsessions and anxiety about food and weight may cause monotonous eating rituals, including reluctance to be seen eating by others. It is not uncommon for people with anorexia nervosa to collect recipes and prepare food for family and friends, but not partake in the food that they prepared. They may also adhere to strict, intensive exercise routines to lose or keep off weight. What Causes Anorexia Nervosa?Anorexia nervosa does not have a single cause, but is related to many different factors. These factors are sometimes divided into predisposing, precipitating, and perpetuating factors, that make a person vulnerable to develop, trigger the onset, and maintain the eating disorder, respectively. Anorexia nervosa often begins as simple dieting to "get in shape" or to "eat healthier" but progresses to extreme and unhealthy weight loss. Social attitudes toward body appearance, family influences, genetics, and neurochemical and developmental factors may contribute to the development and maintenance of anorexia nervosa. A personal or family history of anxiety, depression or obsessive-compulsive habits is common. Although families in which anorexia nervosa occurs were once labeled as having difficulties with conflict resolution, rigidity, intrusiveness, and over-protectiveness, it is now clear that parents do not cause eating disorders. Research suggests that certain areas of the brain function different with an active eating disorder. Who is Affected by Anorexia Nervosa?Anorexia nervosa not only affects individuals who have the diagnosis, but also their family, friends and loved ones. The diagnosis of anorexia nervosa has become more common over the past 20 years. Approximately 90 percent are women between 12 and 25 years of age. Initially found mostly in upper- and middle-class families, anorexia nervosa is now known to affect both sexes and span all ages, socioeconomic, ethnic, and racial groups. What Kind of Person Tends to Get Anorexia Nervosa?The typical profile of a person with anorexia nervosa is an adolescent to young adult female who is perfectionistic, hard-working, introverted, resistant to change and highly self-critical. They also tend to have low self-esteem based on body image distortion and avoid risky or potentially harmful behaviors or situations. However, regardless of the age, sex or other characteristics of the individual, weight control habits focused on reducing intake and increasing output of calories (particularly fats and carbohydrates) initially reduces anxiety, stress and negative mood by giving the person a sense of control in at least one are of her/his life. That is, a sense of mastery and accomplishment is achieved as weight is lost. Over time, these habits cause problems of their own that may increase anxiety, stress and negative mood. What are the Different Types of Anorexia Nervosa?There are two subgroups of behavior aimed at reducing caloric intake, including the following:
What are the Symptoms of Anorexia Nervosa?The following are the most common symptoms of anorexia nervosa. However, each individual may experience symptoms differently. Symptoms may include:
Persons with anorexia nervosa may also be socially withdrawn, irritable, moody, and/or depressed. The symptoms of anorexia nervosa may resemble other medical problems or psychiatric conditions. Always consult your physician for a diagnosis. How is Anorexia Nervosa Diagnosed?Parents, family members, spouses, teachers, coaches, and instructors may be able to identify an individual with anorexia nervosa, although many persons with the disorder initially keep their illness very private and hidden. A detailed history of the individual's behavior from family, parents, and teachers, clinical observations of the person's behavior, contribute to the diagnosis. Because a number of medical conditions can mimic some features of anorexia nervosa, a complete medical evaluation is needed. Family members who note symptoms of anorexia nervosa in a loved one can help by seeking an evaluation and treatment early. Early treatment can often prevent future problems. Anorexia nervosa, and the malnutrition that results, can adversely affect nearly every organ system in the body, increasing the importance of early diagnosis and treatment. Anorexia can be fatal. Consult your physician for more information. Treatment for Anorexia NervosaSpecific treatment for anorexia nervosa will be determined by a physician based on:
Anorexia nervosa is usually treated with a combination of medical care focused on nutritional rehabilitation and modification of behaviors related to eating and exercise to restore body weight and health, and family and/or individual therapy. Treatment should always be based on a comprehensive evaluation of the individual and family. Family therapy is focused on providing support and limit-setting on problem behaviors. Individual therapy usually includes both cognitive and behavioral techniques. Medication may be helpful if depressed moods or worrisome thoughts interfere with daily life. Re-establishing a normal weight may relieve depression on its own, and anti-depressants are not effective at very low body weight. The frequent occurrence of medical complications and the possibility of death during the course of acute and rehabilitative treatment requires both your physician and a nutritionist to be active members of the management team. Families play a vital supportive role in any treatment process. Possible Complications of Anorexia NervosaMedical complications are common in anorexia nervosa. Almost all complications are reversible with weight restoration related to healthy eating and physical activity. Without treatment, complications persist and can worsen, and can be associated with death. The short-term complications include, but are not limited to, the following:
Biochemistry and Eating DisordersTo understand eating disorders, researchers have studied the neuroendocrine system, which is made up of a combination of the central nervous and hormonal systems. The neuroendocrine system regulates multiple functions of the mind and body. It has been found that many of the following regulatory mechanisms may be, to some degree, disturbed in persons with eating disorders:

Genetic/Environmental Factors Related to Eating Disorders Because eating disorders tend to run in families, and female relatives are the most often affected, genetic factors are believed to play a role in the disorders.
Prevention of Anorexia NervosaPreventive measures to reduce the incidence of anorexia nervosa are not known at this time. However, early detection and intervention can reduce the severity of symptoms, enhance the individual's normal growth and development, and improve the quality of life experienced by persons with anorexia nervosa. Decreasing emphasis on weight and focusing on the balance between energy input and output can be useful. Moreover, having healthy adult role models who do not talk about body shape or size, dieting, fat, or losing weight is helpful.
