There are three basic pillars for the development of eating disorders: genetic predisposition, neuro-endocrine-molecular changes in the brain and metabolic response to it. As a result of neuroendocrine research, a close relationship has been found between neuroendocrine functions and symptom domains of psychiatric disorders such as eating disorders and mood disorders. Certain hormones, neurotransmitters and other molecules which might have effect on the basis of eating disorders can be listed as estrogen, serotonin, leptin, ghreline, alpha-melanocyte stimulating hormone, cholecystokinin, dopamine, noradrenaline, brain-derived neurotropic factor, agouti-related protein, neuropeptide-Y, opioids and their receptors, thiamine, zinc, omega-3 acids. In this review, main neuroendocrine-molecular changes and interactions that occur in the eating disorders have been discussed.
