The term anorexia is of Greek origin: a (?, prefix of negation), n (?, link between two vowels) and orexis (??????, appetite) thus meaning a lack of desire to eat. A person who is diagnosed with anorexia nervosa is most commonly referred to with the adjectival form anorexic. The noun form, "anorectic" is generally not used in this context and usually refers to drugs that suppress appetite.

Anorexia nervosa is an illness that usually occurs in teenage girls, but it can also occur in teenage boys, and adult women and men. People with anorexia are obsessed with being thin. They lose a lot of weight and are terrified of gaining weight. They believe they are fat even though they are very thin. Anorexia isn't just a problem with food or weight. It's an attempt to use food and weight to deal with emotional problems.

Anorexia nervosa is characterized by an irrational dread of becoming fat coupled with a relentless pursuit of thinness. People with anorexia go to extremes to reach and maintain a dangerously low body weight. But no matter how much weight is lost, no matter how emaciated they become, it’s never enough. The more the scale dips, the more obsessed they become with food, dieting, and weight loss.

The person suffering with Anorexia may be abnormally sensitive about being perceived as fat, or have a massive fear of becoming fat -- though not all people living with Anorexia have this fear. They may be afraid of losing control over the amount of food they eat, accompanied by the desire to control their emotions and reactions to their emotions. With a low self-esteem and need for acceptance they will turn to obsessive dieting and starvation as a way to control not only their weight, but their feelings and actions regarding the emotions attached. Some also feel that they do not deserve pleasure out of life, and will deprive themselves of situations offering pleasure (including eating).

Causes of Anorexia Nervosa

Culture: Women in the U.S. are under constant pressure to fit a certain ideal of beauty. Seeing images of flawless, thin females everywhere makes it hard for women to feel good about their bodies. More and more, men are also feeling pressure to have a perfect body.

Some experts feel that demands from society and families could possibly be underlying causes for anorexia. For many individuals with anorexia, the destructive cycle begins with the pressure to be thin and attractive. A poor self-image compounds the problem.

Genetic Factors: Anorexia nervosa occurs eight times more often in people who have relatives with the disorder. However, experts do not know exactly what the inherited factor may be. In addition, anorexia nervosa occurs more often in families with a history of depression or alcohol abuse.

Background Many risk factors have been implicated in the development of anorexia nervosa. Little is known about their relative contributions, nor in most cases is it clear whether they are specific to anorexia nervosa or risk factors for all eating disorders or for psychiatric disorder in general.

A variety of psychological, genetic, biological, developmental, and societal factors may contribute to developing this syndrome. Anorexia nervosa may be encouraged because of our society's emphasis on thinness, especially in women.Some evidence suggests differences in brain chemicals in those who develop anorexia.
