Psychogenic eating disorders are disorders regarding nutrition or body weight that do not have an organic cause. Psychogenic eating disorders can manifest in different diseases. Precise differentiation between each disease is usually difficult. Centrally, almost always the topic food is sort of a life focus. Psychogenic disorders are usually an expression of a psychological problem. Often, victims miss structured familiar relations, love, attention or social contacts. Also, a job failure or a desire for love relations can cause eating disorders. One of the best-known eating disorders is anorexia nervosa. Even though this psychosocial disorder is rooted in addiction mechanisms, it is not an addiction by definition. The desire for a thinner figure is rather the life focus.
