Causes of Anorexia Nervosa
The exact cause of anorexia nervosa
is not known. Traumatic events like rape as well as stressful things
like starting a new job, can lead to the onset of anorexia. Genes,
hormones, and chemicals in the brain may be factors in developing
anorexia. Eating disorders also tend to run in families, with female
relatives most often affected. A girl has a 10 to 20 times higher risk
of developing anorexia nervosa, for instance, if she has a sibling with
the disease. Behavioral and environmental influences may also play a
role. Stressful events are likely to increase the risk of eating
disorders as well.
