People with endometriosis might be at higher risk for stroke

According to a study published Thursday in Stroke, a journal of the American Stroke Association (part of the American Heart Association), people with endometriosis — a common gynecological condition marked by pain in the pelvis and back, painful and heavy periods, and infertility — were at a 34 percent greater risk of developing a stroke compared to their non-endometriosis peers.
