Anorexia nervosa (aka "anorexia") is a type of eating disorder characterized by an obsessive fear of being overweight and compulsive under eating, sometimes to the point of starvation. Sufferers will usually present as obviously underweight and may still insist that they are "fat".
Drug treatment for anorexia is focused on treating the underlying psychological problem, which in turn will lead to healthier eating habits and self-treatment of the physical problem.
Common conditions often present alongside anorexia are anxiety, depression, and obsessive-compulsive disorder. Such psychological disorders may play a role in the onset of anorexia, and so their treatment may be one of the first steps toward anorexia treatment. Drugs such as chlorpromazine, an antipsychotic, and certain antidepressants can balance chemicals in the brain and relieve contributing psychological symptoms.
Some research has suggested that a zinc deficiency may contribute to anorexia, due to its association with depression, weight loss, and other appetite disorders. Zinc supplementation has shown promise as part of a comprehensive treatment plan.
Drug treatment alone is not appropriate for anorexics, due to the high risk of self-harm and the distorted self-image most patients carry. It is, however, an important component of a comprehensive treatment plan that should include psychotherapy, nutrition counseling, and dietary supplementation.
