Purpose of review: This review explores the complex interplay between menopause, estrogen decline, lipid metabolism, and gut microbiota alterations. It highlights the physiological and metabolic changes that predispose postmenopausal women to dyslipidemia and increased cardiovascular disease risk, with particular emphasis on the emerging role of the gut microbiota in modulating lipid homeostasis and inflammatory pathways. In addition, it examines the therapeutic potential of microbiota-targeted nutritional strategies to restore metabolic balance and improve cardiometabolic outcomes in postmenopausal women. Recent findings: Recent clinical and experimental evidence indicates that menopause-related hormonal changes and aging are associated with gut microbiota dysbiosis, which may contribute to adverse lipid profiles through mechanisms involving bile acid metabolism, short-chain fatty acid production, and low-grade systemic inflammation. Associations between specific microbial taxa and lipid metabolic patterns have been reported; however, findings remain heterogeneous and causal relationships are difficult to establish due to confounding factors such as diet, lifestyle, and medication use. Nutritional interventions aimed at modulating the gut microbiota—including Mediterranean, plant-based, and DASH dietary patterns, increased dietary fiber intake, and supplementation with prebiotics, probiotics, polyphenols, phytoestrogens, and omega-3 fatty acids—have shown potential to improve lipid profiles and cardiometabolic risk markers. Summary: The gut microbiota emerges as a relevant contributor to menopause-associated dyslipidemia and cardiovascular risk. While microbiota-targeted nutritional strategies are promising, further longitudinal and interventional studies are needed to clarify causal pathways and identify clinically actionable microbial signatures. Integrating microbiome-informed nutritional approaches into clinical practice may represent a future strategy to improve cardiometabolic health in postmenopausal women.

Abstract
Purpose of review: This review explores the complex interplay between menopause, estrogen decline, lipid metabolism, and gut microbiota alterations. It highlights the physiological and metabolic changes that predispose postmenopausal women to dyslipidemia and increased cardiovascular disease risk, with particular emphasis on the emerging role of the gut microbiota in modulating lipid homeostasis and inflammatory pathways. In addition, it examines the therapeutic potential of microbiota-targeted nutritional strategies to restore metabolic balance and improve cardiometabolic outcomes in postmenopausal women. Recent findings: Recent clinical and experimental evidence indicates that menopause-related hormonal changes and aging are associated with gut microbiota dysbiosis, which may contribute to adverse lipid profiles through mechanisms involving bile acid metabolism, short-chain fatty acid production, and low-grade systemic inflammation. Associations between specific microbial taxa and lipid metabolic patterns have been reported; however, findings remain heterogeneous and causal relationships are difficult to establish due to confounding factors such as diet, lifestyle, and medication use. Nutritional interventions aimed at modulating the gut microbiota—including Mediterranean, plant-based, and DASH dietary patterns, increased dietary fiber intake, and supplementation with prebiotics, probiotics, polyphenols, phytoestrogens, and omega-3 fatty acids—have shown potential to improve lipid profiles and cardiometabolic risk markers. Summary: The gut microbiota emerges as a relevant contributor to menopause-associated dyslipidemia and cardiovascular risk. While microbiota-targeted nutritional strategies are promising, further longitudinal and interventional studies are needed to clarify causal pathways and identify clinically actionable microbial signatures.
