Abstract:In Bulimia nervosa, a complex syndrome of clinical symptoms is formed. The patient who will mostly attempt to keep her syndrome hidden is subjected to diverse alterations that can be observed in her, her family and society. Somatic alterations in Bulimia nervosa patients are depicted, family idiosyncrasies in families with a bulimic member are highlighted. The research project on Bulimia nervosa 2007-2010 at the University of Heidelberg is outlined, leading to a pondering of psychodynamic symptom formation. Aspects of oedipality are shown in a case vignette of an 18-year-old female bulimic patient experiencing and restaging guilt and seduction issues. Some leads at mass society´s influence on the way symptom formations appear today are to broaden the perspective by means of I. Hassan´s cultural characteristics of modernity and postmodernity. After a close look at alterations in clinics of bulimic patients that shows how the cultural paradigm of postmodernity is reflected in the patient, Bulimia nervosa, often as a low profile phenomenon in daily gynaecologic and primary care practice, is declared requiring apt intervening in clinical treatment, and conceptualizing of human developmental processes in new ways. Psychosomatic Medicine will benefit from cross-referencing on psyche, body, and society, in order to understand psychosomatic condition even better than before.
