Anorexia Nervosa Health Article

Causes & symptoms

Anorexia is a disorder that results from the interaction of cultural and interpersonal as well as biological factors. While the precise cause of the disease is not known, it has been linked to the following:

Social influences

The rising incidence of anorexia is thought to reflect the present idealization of thinness as a badge of upper-class status as well as of female beauty. In addition, the increase in cases of anorexia includes "copycat" behavior, with some patients developing the disorder from imitating other girls.

The onset of anorexia in adolescence is attributed to a developmental crisis caused by girls' changing bodies coupled with society's overemphasis on women's looks. The increasing influence of the mass media in spreading and reinforcing gender stereotypes has also been noted.

Occupational goals

The risk of developing anorexia is higher among adolescents preparing for careers that require attention to weight and/or appearance. These high-risk groups include dancers, fashion models, professional athletes (including gymnasts, skaters, long-distance runners, and jockeys), and actresses.

Genetic and biological influences

Women whose biological mothers or sisters have the disorder appear to be at increased risk.

Psychological factors

A number of theories have been advanced to explain the psychological aspects of the disorder. No single explanation

covers all cases. Anorexia nervosa has been interpreted as:

• A rejection of female sexual maturity. This rejection is variously interpreted as a desire to remain a child, or as a desire to resemble men as closely as possible.
• A reaction to sexual abuse or assault.
• A desire to appear as fragile and non-threatening as possible. This hypothesis reflects the idea that female passivity and weakness are attractive to men.
• Overemphasis on control, autonomy, and independence. Some anorexics come from achievement-oriented families that stress physical fitness and dieting. Many anorexics are perfectionists and "driven" about schoolwork and other matters in addition to weight control.
• Evidence of family dysfunction. In some families, a daughter's eating disorder serves as a distraction from marital discord or other family tensions.
• Inability to interpret the body's hunger signals accurately due to early experiences of inappropriate feeding.
