What Is Endometriosis?
Reviewed: Dr. Gromatzky
2. Risk Factors
Some of the risk factors for endometriosis include early age of menarche (first period), family history of endometriosis (six fold increase in incidence if there is an affected first-degree relative), heavy bleeding during menses (menorrhagia), short menstrual cycles (less than 27 days), and long duration of menstrual flow (more than 7 days).
Additional risk factors include: delayed childbearing, iron deficiency, hypoxia (low oxygen), defects in the fallopian tubes and uterus (such as obstruction of menstrual outflow), altered immune response, environmental toxins (such as dioxins), late menopause, and iatrogenic deposition (due to gynecologic procedures such as cesarean sections).
