Perimenopause and menopause are not defined by a single hormone deficiency, but by volatility and imbalance that affect sleep, mood, bone, brain, and cardiovascular health. This article explains how estrogen and progesterone change over time, why symptoms are often dismissed, and how thoughtful, individualized care can protect long-term health and resilience.
