Eating Disorders: Facts About Eating Disorders and the Search for Solutions

Eating is controlled by many factors, including appetite, food availability, family, peers, and cultural practices, and attempts at voluntary control. Dieting to a body weight leaner than needed for health is highly promoted by current fashion trends, sales campaigns for special foods, and in some activities and professions. Eating disorders involve serious disturbances in eating behaviour, such as extreme and unhealthy reduction of food intake or severe overeating, as well as feelings of distress or extreme concern about body shape or weight.

Eating disorders are not due to a failure of will or behaviour; rather, they are real, treatable medical illnesses in which certain maladaptive (适应不良的) patterns of eating take on a life of their own. The main types of eating disorders are anorexia nervosa (厌食症) and bulimia nervosa (暴食症). A third type, binge-eating (暴食行为) disorder, has been suggested but has not yet been approved as a formal psychiatric diagnosis. Eating disorders frequently develop during adolescence or early adulthood, but some reports indicate their onset can occur during childhood or later in adulthood.

Eating disorders frequently co-occur with other psychiatric disorders such as depression, substance abuse, and anxiety disorders. In addition, people who suffer from eating disorders can experience a wide range of physical health complications, including serious heart conditions and kidney failure which may lead to death. Recognition of eating disorders as real and treatable diseases, therefore, is critically important.

Females are much more likely than males to develop an eating disorder. Only an estimated 5 to 15 percent of people with anorexia or bulimia and an estimated 35 percent of those with binge-eating disorder are male.

Anorexia Nervosa

An estimated 0.5 to 3.7 percent of females suffer from anorexia nervosa in their lifetime. Symptoms of anorexia nervosa include:

resistance to maintaining body weight at or above a minimally normal weight tot age and height

intense fear of gaining weight or becoming fat, even though underweight

disturbance in the way in which one's body weight or shape is experienced, undue influence of body weight or shape on self-evaluation, or denial of the seriousness of the current low body weight

infrequent or absent menstrual periods (in females who have reached puberty [青春期])

People with this disorder see themselves as overweight even though they are dangerously thin. The process of eating becomes an obsession. Unusual eating habits develop, such as avoiding food and meals, picking out a few foods and eating these in small quantities, or carefully weighing and portioning food. People with anorexia may repeatedly check their body weight, and many engage in other techniques to control their weight, such as intense and compulsive exercise, or purging by means of vomiting and abuse of laxatives, enemas, and diuretics. Girls with anorexia often experience a delayed onset of their first menstrual period.

Bulimia Nervosa

An estimated 1.1 percent to 4.2 percent of females have bulimia nervosa in their lifetime. Symptoms of bulimia nervosa include:

recurrent episodes of binge eating, characterized by eating an excessive amount of food within a discrete period of time and by a sense of lack of control over eating during the episode

recurrent inappropriate compensatory behaviour in order to prevent weight gain, such as self-induced vomiting or misuse of laxatives, diuretics, enemas, or other medications (purging); fasting; or excessive exercise

the binge eating and inappropriate compensatory behaviour both occur, on average, at least twice a week for 3 months
