When chronicity meets cyclicity: The cultivation of embodied knowledge and selfhood by cis-gender women with cystic fibrosis

This article offers the case of cystic fibrosis (CF), a multi-system disease, to illustrate how individuals with chronic illness cultivate and apply embodied knowledge to optimize their well-being. We identified three interrelated processes that occur when disease chronicity and menstrual cyclicity meet: 1) knowledge production with a period-tracking app; 2) application of embodied knowledge to manage life with menstrual-related CF symptoms; 3) cultivation of the body-self as a menstruating woman with CF. These dynamic processes capture how cis-gender women with CF attune to their bodies, navigate their illness, and situate themselves within their lifeworlds. Genetic conditions like CF are apt for studying these processes because adults have managed their disease for decades, with longitudinal experience that often exceeds that of their clinicians. Our evidence elucidates the co-constitutive nature of chronic disease, gendered subjectivity, and biological processes in flux. We explored the menstrual cyclicity of chronic disease symptoms by having 72 participants track their CF symptoms across 4 menstrual cycles on a customized period-tracking app. We performed semi-structured interviews with 20 participants to understand how they interpreted these cyclical CF symptoms. We learned that digital tracking attuned participants to monthly fluctuations in CF symptoms. They applied this knowledge to manage their lives and shape their sense of self. We argue that women with CF produce distinct embodied knowledge during their reproductive years, shaping their illness experience, disease management, overall health, quality of life, and selfhood. The dynamics we describe may reflect broader patterns by which women with other chronic illnesses experience their bodies and understand themselves in the world.
