Abstract
The hypoestrogenic period after menopause and associated metabolic imbalance might facilitate the onset of non-alcoholic fatty liver disease (NAFLD) and its progression. The prevalence of NAFLD increases in patients experiencing premature ovarian insufficiency, as well as surgical or natural menopause. The postmenopausal period is characterized by dyslipidemia and insulin resistance associated with an increased influx of free fatty acids to the liver with consequent steatosis and further progression of NAFLD. More than half of postmenopausal women with diabetes mellitus type 2 suffer from NAFLD. It is suggested that estrogens slow the progression of chronic liver diseases by suppression of inflammation, improvement of mitochondrial function, alleviation of oxidative stress, insulin resistance, and fibrogenesis. The hyperandrogenic state of polycystic ovary syndrome (PCOS) is associated with the development of NAFLD in women of reproductive age, but it is difficult to extend these findings to menopause due to inappropriate diagnosis of PCOS after menopause. Lifestyle intervention, including physical activity and dietary regimens, remains the first-line preventive and therapeutic option for NAFLD. There are contradictory reports on the use of menopausal hormonal therapy (MHT) and NAFLD. It is necessary to investigate the potential effects of estradiol dose, progesterone type, selective estrogen receptor modulators and tissue-selective estrogen complex compounds on NAFLD development and progression in postmenopausal women. The present review aims to explore the pathophysiological and clinical aspects of liver metabolic disturbances in women after menopause, focusing on the possible preventive and therapeutic strategies in NAFLD, including the potential role of MHT.

Women's Health Endocrine Update.
Kapoor, E, Faubion, S, Hines, S, Stuenkel, CA
Journal of women's health (2002). 2017;(12):1365-1368
Abstract
The clinical update serves as a brief review of recently published, high-impact, and potentially practice changing journal articles summarized for our readers. Topics include menopause, sexual dysfunction, breast health, contraception, osteoporosis, and cardiovascular disease. In this clinical update, we selected four recent high-impact publications related to endocrine issues in women. We have chosen to highlight research on subclinical hypothyroidism during pregnancy and adverse pregnancy outcomes, including cognitive outcomes in offspring; the progression of metabolic syndrome severity during the menopausal transition; and the association of diabetes and metformin use with cancer risk and mortality.

Hypertension in postmenopausal women: how to approach hypertension in menopause.
Modena, MG
High blood pressure & cardiovascular prevention : the official journal of the Italian Society of Hypertension. 2014;(3):201-4
Abstract
During fertile life women are usually normo or hypotensive. Hypertension may appear during pregnancy and this represents a peculiar phenomenon increasing nowadays for delay time of pregnancy. Gestational hypertension appears partially similar to hypertension in the context of metabolic syndrome for a similar condition of increased waste circumference. Parity, for the same pathogenesis, has been reported to be associated to peri and postmenopausal hypertension, not confirmed by our study of parous women with transitional non persistent perimenopausal hypertension. Estrogen's deficiency inducing endothelial dysfunction and increased body mass index are the main cause for hypertension in this phase of life. For these reasons lifestyle modification, diet and endothelial active drugs represent the ideal treatment. Antioxidant agents may have a role in prevention and treatment of hypertension. In conclusion, hypertension in women represents a peculiar constellation of different biological and pathogenic factors, which need a specific gender related approach, independent from the male model.

Abstract
A woman's risk for metabolic syndrome (MS) increases at menopause, with an associated increase in risk for cardiovascular disease. We hypothesized that early menopause-related changes in platelet activity and concentrations of microvesicles derived from activated blood and vascular cells provide a mechanistic link to the early atherothrombotic process. Thus, platelet functions and cellular origin of blood-borne microvesicles in recently menopausal women (n = 118) enrolled in the Kronos Early Estrogen Prevention Study were correlated with components of MS and noninvasive measures of cardiovascular disease [carotid artery intima medial thickness (CIMT), coronary artery calcium (CAC) score, and endothelial reactive hyperemic index (RHI)]. Specific to individual components of the MS pentad, platelet number increased with increasing waist circumference, and platelet secretion of ATP and expression of P-selectin decreased with increasing blood glucose (p = 0.005) and blood pressure (p < 0.05), respectively. Waist circumference and systolic blood pressure were independently associated with monocyte- and endothelium-derived microvesicles (p < 0.05). Platelet-derived and total procoagulant phosphatidylserine-positive microvesicles, and systolic blood pressure correlated with CIMT (p < 0.05), but not with CAC or RHI. In summary, among recently menopausal women, specific platelet functions and concentrations of circulating activated cell membrane-derived procoagulant microvesicles change with individual components of MS. These cellular changes may explain in part how menopause contributes to MS and, eventually, to cardiovascular disease.

Insulin resistance and management of the menopause: a clinical hypothesis in practice.
Whitcroft, S, Herriot, A
Menopause international. 2011;(1):24-8
Abstract
Insulin resistance (IR) is associated with a number of metabolic abnormalities including glucose intolerance, dyslipidemia and central obesity (the metabolic syndrome), which predispose to cardiovascular disease, diabetes mellitus and some cancers. The incidence of many of these conditions increases after the menopause, a time when IR also increases. Medical intervention to help alleviate menopausal symptoms, frequently vasomotor in origin, usually involves hormone replacement therapy (HRT), but some women may only experience partial symptom relief. We have hypothesized that this may be due to concurrent IR. Our approach is therefore to manage menopausal symptoms in conjunction with the treatment of any concurrent IR, achieved through a combination of hormone replacement, dietary intervention and, if necessary, an insulin sensitizer. We suggest that this approach may not only improve symptom relief but may also reduce the risk of developing more serious health complaints in the future.

Metabolic implications of menopause.
Polotsky, HN, Polotsky, AJ
Seminars in reproductive medicine. 2010;(5):426-34
Abstract
The incidence of metabolic syndrome increases substantially during perimenopause and early menopause. Postmenopausal women are at a higher risk of hypertension, proatherogenic lipid changes, diabetes, and severe cardiovascular disease as compared with their premenopausal counterparts. Whether or not menopause has a causative contribution to the deteriorating metabolic profile that is independent of chronological aging has been a subject of many studies. Menopausal transition is associated with significant weight gain (2 to 2.5 kg over 3 years on average), which is not dissimilar to that in premenopausal women of like age. Concomitantly, there is an increase in abdominal adiposity and a decrease in energy expenditure, phenomena that have been postulated to explain the higher risk of metabolic syndrome and increases in cholesterol and triglycerides. Hypertension and diabetes become more prevalent with age and should be timely diagnosed and treated. Lifestyle changes including moderately decreased caloric intake and aerobic exercise could prevent proatherogenic changes and weight gain observed with aging. Accurate prediction of cardiovascular risk in midlife women is essential to help identify the subset of women who are likely to benefit from intensive management of metabolic risk factors. This review focuses on metabolic changes associated with menopausal transition, specifically alterations in weight, waist circumference, body fat distribution, energy expenditure, and circulating biomarkers including adipokines.

Cardiovascular risk in menopausal women and prevalent related co-morbid conditions: facing the post-Women's Health Initiative era.
Pérez-López, FR, Chedraui, P, Gilbert, JJ, Pérez-Roncero, G
Fertility and sterility. 2009;(4):1171-1186
Abstract
OBJECTIVE To review scientific publications regarding cardiovascular risk during the menopausal years and that related to currently recognized highly prevalent co-morbid factors within this period. METHODS Citations were selected from a PubMed search and the authors' files according to their clinical and experimental relevance. RESULTS AND DISCUSSION Although experimental and some observational data have supported the fact that estrogens are beneficial for the female vascular system, these positive actions have been challenged by the results of the Women's Health Initiative trial and the Million Women Study, which demonstrated an increase in cardiovascular risk and related adverse events. The role of hormone therapy for the menopause has shifted from a preventive use to a limited role in symptom management, for which it remains the most effective intervention. Baseline evaluation of menopausal women should include individual cardiovascular risk assessment, including hypertension, dyslipidemia, elevated body weight, and the metabolic syndrome. Concomitantly, new factors influencing cardiovascular risk have been delineated among postmenopausal women, namely sleeping disorders, depression, vitamin D insufficiency, rheumatoid arthritis, sexual dysfunction, stress, and psychosocial factors. Therefore, a new landscape may be recognized for menopausal women management. Precise evaluation and treatment of each factor should be separately assessed to improve quality of life and reduce cardiovascular disease prevalence. At present, cardiovascular risk reduction strategies are a requisite (albeit underused) for menopausal women. These include education in terms of health, healthy lifestyle, and pharmacologic preventive interventions to reduce co-morbid conditions.
