At what age do women typically enter perimenopause?

Women typically enter perimenopause around age 40. Perimenopause is the transitional phase leading up to menopause, during which hormonal fluctuations begin and menstrual cycles can become irregular. This phase can last several years, often starting in a woman's 40s. The changes experienced during this time can include alterations in menstrual regularity, hot flashes, night sweats, and other symptoms related to dropping estrogen levels.

Understanding the age at which perimenopause begins is essential for women as it helps in anticipating and managing the physical and emotional changes that may arise during this period. Recognizing this stage can also facilitate discussions with healthcare providers about treatment options and lifestyle adjustments that can ease symptoms as women transition towards menopause.
