The Definition of Endometriosis

What is the correct definition of Endometriosis?

Endometriosis (nicknamed "Endo") is a chronic and often painful whole-body disease that affects millions worldwide. A current, formal definition of Endometriosis:

“A systemic, inflammatory disease characterized at surgery by the presence of endometrium-like tissue found outside the uterus, usually with an associated inflammatory process. It is a spectrum disease with a variety of subtypes and clinical presentations, and pain, inflammation, infertility, development of endometriomas (“chocolate cysts”), fibrosis, formation of adhesions (fibrous bands of dense tissue), GI and other organ dysfunction, and much more are common with endometriosis” (Center for Endometriosis Care, Int’l Endometriosis Working Group, 2021)
