Is There an Association Between Endometriosis, Early Menopause, and Cardiovascular Disease?

Large-scale studies show endometriosis linked to earlier menopause onset. Recent research targeting women with laparoscopically diagnosed endometriosis found an increase in cases of early natural menopause. Furthermore, recent large-scale cohort studies have found a correlation between endometriosis and an increased risk of cardiovascular disease (CVD). Understanding the causality of early menopause, particularly natural menopause, and cardiovascular risks in women with endometriosis could help medical professionals develop effective strategies for early prevention and new therapies. Endometriosis, early menopause, and cardiovascular risks may be linked by primary or secondary mechanisms. Primary mechanisms involve shared pathways that can lead to all morbidities, while secondary occur due to delayed consequences of management strategies. In these large-scale cohort studies, relevant risk and confounding factors, such as oophorectomy, were considered to refine estimates of associations. However, none of the studies considered endometriotic cystectomy, a globally accepted treatment for endometriosis-associated pelvic pain and infertility, as a mediating factor. There is substantial evidence to indicate that endometriotic cystectomy harms ovarian reserve and may lead to early menopause in cases of multiple surgeries or bilateral cases. Early menopause is a well-established risk factor for CVD. To thoroughly examine the link between endometriosis and early menopause, particularly natural menopause, and their connection with cardiovascular risks, it is imperative to consider all the possible factors that may affect the results, such as endometriotic cystectomy. This will enable us to obtain the most accurate and adjusted hazard ratio.
