Hot flashes and sweating occur during menopause. It is because ovarian function has declined and estrogen secretion has decreased, so hot flashes and excessive sweating occur. Clinical symptoms of decreased estrogen occur during menopause because ovarian function has declined and estrogen secretion has decreased. So clinically, if relatively fat people, menopausal symptoms will be reduced. At the same time, estradiol can be converted to each other, mainly in the fat muscle or liver, kidney and brain tissue. In relatively fat people, because fat is converted into estradiol, the symptoms of menopause will be relatively lower.
