What causes Anorexia nervosa?
The exact causes of anorexia nervosa are unknown. Many factors probably are involved. Genes and hormones may play a role. Social attitudes promoting very thin body types may also be involved. Family conflicts are no longer thought to contribute to this or other eating disorders. Anorexia usually begins during the teen years or young adulthood. It is more common in females, but may also be seen in males. The disorder is seen mainly in white women who are high academic achievers and who have a goal-oriented family or personality. </s>
