Think all hot flashes are created equal? Think again. According to results released from the Study of Women’s Health Across the Nation (SWAN), some women are "early onset" and have hot flashes which end at menopause. Meanwhile, others are “late onset” and don’t get hot flashes until after their last period. The study also found that one in four midlife women are "super flashers" — who have hot flashes before, during and perhaps years after menopause.

And then there are the “super flashers.” This unlucky group includes one in four midlife women. The super flasher begins to experience hot flashes relatively early in life, similar to the early onset group. But her symptoms continue well past menopause, like those in the late onset group. Her symptoms can last 15 years or more.

"Low-frequency hot flashes were not a problem from a cardiovascular standpoint. The women we need to pay close attention are the 'super flashers' — the women who report a lot," she told Medscape Medical News.
