New long-term research shows that hot flashes continue, on average, for five years after menopause. More than a third of women can experience hot flashes for up to ten or more years after menopause.
A recent study evaluated 255 women in the Penn Ovarian Aging Study who reached natural menopause over a 16-year period. The results indicate that 80 percent reported moderate to severe hot flashes, 17 percent had only mild hot flashes, and three percent reported no hot flashes.
