In this article we explore the relationship between asthma and stigma, drawing on 31 interviews with young people (aged 5-17) in Ireland. Participants with mild to moderate asthma were recruited from Traveller and middle-class settled communities. Themes derived from an abductive approach to data analysis and a critical appreciation of Goffmanesque sociology, include: asthma as a discreditable stigma, negative social reactions (real, imagined and anticipated), and stigma management. Going beyond a personal tragedy model, we reflect upon macro-social structures (e.g. ethnicity, class, gender) which underlie stigma and the management of a potentially spoiled identity. This raises issues about the politics of chronic illness, embodying health identities and efforts to tackle stigma in neoliberal times.
