Oprah Winfrey is speaking out to save other women from suffering in silence. In her upcoming Hulu special, Winfrey will explore menopause and its various impacts on women.

Winfrey, 71, said that in addition to a loss of concentration, she also suffered from heart palpitations -- a sensation of a racing or irregular heartbeat -- which she said she did not know were a symptom of menopause, the time in life when a woman's periods stop permanently.

Oprah Winfrey is breaking the silence on menopause with her new Hulu special, “An Oprah Winfrey Special: The Menopause Revolution,” aiming to support women by sharing her own challenging experiences.
