["Sociology of Health & Illness, EarlyView. ", "\nAbstract\nIn recent years, the term ‘medical gaslighting’ and accompanying accounts of self‐identified women experiencing invalidation, dismissal and inadequate care have proliferated in the media. Gaslighting has primarily been conceptualized in the field of psychology as a phenomenon within interpersonal relationships. Following the work of Paige Sweet (American Sociological Review, 84, 2019, 851), I argue that a sociological explanation is necessary. Such an explanation illustrates how medical gaslighting is not simply an interpersonal exchange, but the result of deeply embedded and largely unchallenged ideologies underpinning health‐care services. Through an intersectional feminist and Foucauldian analysis, I illuminate the ideological structures of western medicine that allow for medical gaslighting to be commonplace in the lives of women, transgender, intersex, queer and racialized individuals seeking health care. Importantly, these are not mutually exclusive groups, and I use the term bio‐Others to highlight and connect how those with embodied differences are treated in medicine. This article indicates the importance of opening a robust discussion about the sociology of medical gaslighting, so that we might better understand what structural barriers people of marginalized social locations face in accessing quality health care and develop creative solutions to challenge health‐care inequities.\n"]
