This paper explores Nietzsche's approach to the question of illness. It develops an account of Nietzsche's ideas in the wake of Arthur W. Frank's discussion of the shortcomings of modern medicine and narrative theory. Nietzsche's approach to illness is then explored in the context of On the Genealogy of Morality and his conception of the human being as "the sick animal". This account, it is argued, allows for Nietzsche to develop a conception of suffering that refuses to reduce it to modernist restitutive conceptions of well-being. Instead, Nietzsche advocates a more nuanced conception of varying degrees of health. This, it is argued, can be developed into a model that allows for a more satisfying conception of the relation between medical practitioner and patient.
