What Causes Anorexia?

Anorexia Nervosa is a potentially life-threatening eating disorder characterized by the inability to maintain a normal weight, a fear of weight gain, dietary habits that prevent weight gain, and a disturbance in the way in which body weight and shape are perceived.  A newly published study indicates that there may be genetic underpinnings for anorexia.  The study results also showed that anorexia may begin first as a disorder of rapid metabolism. This emerging understanding may help with improving disease outcomes with improved psychiatric and metabolic treatment options. (Image from genome.gov )
