The rhetoric of health and medicine (RHM) is a growing and vibrant area of inquiry incorporating scholars working across a variety of fields and disciplines. While this makes it a source for rich and innovative scholarship, this emerging field is in need of a guiding text that can bring together the disparate work spread across multiple disciplines and institutional spaces. Rhetoric of Health and Medicine As/Is: Theories and Approaches for the Field answers this call by providing an in-depth and wide-reaching analysis of the state of the rhetoric of health and medicine and offering core concepts and critical theories to ground research moving forward. With a foreword by Judy Segal and in sections that address interdisciplinary perspectives, representations of health and illness in online spaces, and health activism and advocacy, this volume proceeds in a unique format: essays tackle these key topic areas through case studies ranging from food and its relation to public health, to apps that track fertility, to mental health and disability, to racial disparities that exist in public health campaigns about sudden infant death syndrome (SIDS). The essays within each section are then followed by responses from prominent scholars in the rhetoric of health and medicine–including John Lyne, J. Blake Scott, and Lisa Keranen–who take on the central theme and discuss how the theory or concept under study can and should evolve in the next stages of research. Unifying the essays is a consideration of RHM as a theoretical construct guiding research and thinking alongside the conceptual parameters that constitute what RHM is and can be in practice. In asking questions about the role of rhetoric–both as analytic and productive framework–in health and medicine, this volume engages with broader theoretical and ethical concerns about our current healthcare system and how healthcare and medical issues circulate in all the social, cultural, economic, and political aspects of our world.
