The focus of this research study was the exploration of the phenomenon of stigmatization of obese persons by nurses. The philosophical tradition of Phenomenology based on Heidegger's view of the person guided the researchers in uncovering the meaning of stigmatization for eight chronically ill individuals with a body mass index greater than 30. Stigmatization by nurses for this group of medically obese women meant being exposed to unintentional harm, presuppositions, and reluctant care. Perceptions of stigma were manifested in shame, marginalization, and anxiety in seeking health care. Nursing care could advance positive outcomes when including non-discriminatory care related to weight in the total care needs identified for obese patients.
