Myasthenia gravis (MG) is a chronic, complex, autoimmune disorder. One-third of MG patients were complicated by severe disabilities and unable to return to ordinary life. To recognize MG patients’ illness experiences including their difficulties and coping strategies, we enrolled 20 patients, aged 28 to 72 years, using an explorative qualitative approach. The mean duration of illness was 13.5±7.3 years. Data were derived by content analysis and categorized into three stages with five themes. The first stage was the obscure stagebegging of transposition. The second was the treatment stage - falling into the limbo, and struggling tangle in interpersonal. And the last stage was the adaptation stage - finding ways to stabilize their lives with illness, and reestablishing self-worth. Living with MG is the patients’ unwavering responsibility. Their family and friends play important roles in supporting as well. Moreover, the peer support groups of MG could share their experiences one another and help provide information they need. The importance of support groups should be valued. In addition, the health care providers ought to provide proper observation and care of physical, psychological, social and spiritual dimensions. If necessary, we should refer patient to support groups timely in order to facilitate the seamless care.
