Rhetoric, commonly understood as the art, practice, and analysis of persuasion, has longstanding connections to medicine and health. Rhetorical scholars, or rhetoricians, have increasingly applied rhetorical theories, concepts, and methods to the texts, contexts, discourses, practices, materials, and digital and visual artifacts related to health and medicine. As an emerging interdisciplinary subfield, the rhetoric of health and medicine seeks to uncover how symbolic patterns shape thought and action in health and medical texts, discourses, settings, and materials. In practice, rhetoricians who study health and medicine draw from the standard modes of rhetorical analysis, such as rhetorical criticism and rhetorical historiography, as well as from social science methods—including participant observation, interviewing, content analysis, and visual mapping—in order to deepen understanding of how language functions across health and medical objects, issues, and discussions. The objects of analysis for rhetorical studies of health and medicine span medical research, education, and clinical practice from laboratory notes to provider–patient interaction; health policymaking and practice from draft policies through standards of care; public health texts and artifacts; consumer health practices and patient advocacy on- and offline; public discourses about disease, death, bodies, illness, wellness, and health; online and digital health information; popular entertainments and medical dramas; and alternative and complementary medicine. Despite its methodological breadth, rhetorical approaches to science and medicine consistently involve the systematic examination and production of symbolic exchanges occurring across interactional, institutional, and public contexts to determine how individuals and groups create knowledge, meanings, identities, understandings, and courses of action about health and illness.
