The menopausal transition, also known as perimenopause, is the period leading up to menopause when a woman's body undergoes hormonal changes. This phase typically begins in a woman's 40s but can start earlier or later. During this time, levels of estrogen and progesterone fluctuate, leading to various physical and emotional symptoms. Common symptoms of the menopausal transition include irregular menstrual cycles, hot flashes, night sweats, and mood swings. These changes can last for several years before menstruation completely stops, marking the official onset of menopause. Understanding this transition can help women manage their symptoms and seek appropriate support.
