Does high or low serotonin level in brain cause enorexia?

Anorexia nervosa: The cause of this is widely debated. Predominantly in teen age women it is promoted by self image of a fat person inhibiting ingestion of food or leading to self-induced vomiting. Theories have involved hypothalamic dysfunction, receptor sites for hunger inducing hormone, and altered self-imaging induced by inappropiate parenting or other psychological dysfunction.
