Co-morbidity of type 1 diabetes and endometriosis: bringing a new paradigm into focus.

Type 1 diabetes mellitus and endometriosis separately affect millions of women worldwide. Reproductive-age women diagnosed with type 1 diabetes may also suffer from endometriosis, but the asymptomatic pre-clinical period of highly variable duration for each condition can lead to challenges in the timely recognition of co-morbid disease onset and misdiagnosis. While knowledge of the pathogenesis of each condition has grown substantially, co-morbid endometriosis and type 1 diabetes has not been widely considered and much less addressed. This review discusses the molecular rationale for the likelihood of their co-existence, and prospects for improvements in therapeutic strategies and reduced complications, if this paradigm is included as a significant variable in disease management.
