Perimenopause is the transitional phase leading up to menopause, characterized by hormonal fluctuations that can cause various physical and emotional changes. This period typically begins in a woman's 40s, but can start earlier, and lasts until menopause occurs, marking the end of menstrual cycles. The hormonal changes during perimenopause affect the regulation of the menstrual cycle and the production of hormones such as estrogen and progesterone.
