what causes hot flashes after menopause
A hot flash, sometimes called a hot flush, is a quick feeling of heat and sometimes a red, flushed face and sweating. The exact cause of hot flashes is not known, but may be related to changes in circulation. Hot flashes happen when the blood vessels near the skin's surface dilate to cool. A woman may also sweat to cool down her body. And some women have a rapid heart rate or chills. Hot flashes with sweating can also happen at night.
