Endometriosis is a hidden disability that disrupts multiple aspects of life—school, work, social, etc. Women living with endometriosis have often felt misunderstood and unsupported by their doctors, family, friends, teachers, and colleagues. To better understand their experiences with the condition, this exploratory study seeks to understand, 1) How women with endometriosis use Facebook to portray their experiences, and 2) What words, phrases, or images do they use to convey those experiences? To answer these questions, virtual participant observation was conducted in an online support group for women with endometriosis. Three central themes emerged from the observations of the group: dealing with mental and physical health challenges, learning to understand and manage the symptoms in relation to endometriosis, and understanding disease as part of identity. By examining the virtual lives of women living with endometriosis, we can bring light to the challenges and the issues they face and how they use social media for support.
