The empirical study considered in the article involved qualitative interviews to women and non-binary people with chronic illness. The article explores the narratives of medical gaslighting and analyses forms of injustice and violence related to it. It also analyses the consequences of gaslighting on the individual and collective level, stressing the need to tackle it as a structural oppression.
