In healthy postmenopausal women, estrogen or hormone replacement therapy (E
RT or HRT) can alleviate menopausal symptoms and prevent osteoporosis and m
ay also protect against cardiovascular disease (CVD). In addition to improv
ing lipid metabolism, there are reports that estrogen also improves paramet
ers regulating carbohydrate metabolism, including insulin resistance, in he
althy women. Therefore, it is likely that ERT or HRT would also benefit wom
en with type 2 diabetes, not only in relieving menopausal symptoms but also
in improving the metabolic abnormalities associated with diabetes and in p
reventing cardiovascular disease.
