Lipid metabolism in women: A review

Abstract

The menopausal transition, defined by the cessation of menstruation due to declining ovarian follicular function, results in a marked decrease in endogenous estrogen levels. This phase is associated with significant metabolic changes and a shift towards a more atherogenic lipid profile. Specifically, there are increases in total cholesterol, low-density lipoprotein cholesterol, and triglycerides and unfavorable alterations in high-density lipoprotein cholesterol and lipoprotein(a) levels. These lipid changes, which contribute to an increased risk of atherosclerotic cardiovascular disease, are influenced by diminished estrogen levels and chronological aging. However, the specific mechanisms driving this increased risk are not fully understood. A thorough understanding of these lipid profile alterations is important for developing strategies to reduce cardiovascular disease risk in women. This review provides an overview of how lipid metabolism is affected during the menopausal transition and the resulting implications for cardiovascular risk.
