What is perimenopause?
Perimenopause (PER-ee-MEN-ohpawz), which is sometimes called "the menopausal transition," is the time leading up to a woman's last period. During this time a woman will have changes in her levels of the hormones estrogen (ES-truh-jin) and progesterone (proh-JES-tuh-RONE). These changes may cause symptoms like hot flashes. Some symptoms can last for months or years after a woman’s period stops. After menopause, a woman is in postmenopause, which lasts the rest of her life.
