Estrogen is one of the most influential hormones in a woman’s body, shaping everything from metabolism and mood to brain function, bone strength, cardiovascular health, and the integrity of skin, hair, and vaginal tissue.
During the reproductive years, estrogen follows a predictable monthly rhythm. But in the 40s, levels begin to fluctuate dramatically, often rising higher than ever before and then dropping lower than the body is used to. These swings, followed by a long-term decline during menopause, can trigger symptoms that feel sudden, confusing, or unrelated.
This tag brings together evidence-based insights on how estrogen works, how it changes during perimenopause and menopause, and how those shifts affect energy, sleep, weight, mood, cognition, sexual health, and long-term disease risk. Topics include estrogen’s role in brain health, bone density, cardiovascular protection, metabolic regulation, and the gut–hormone axis, as well as what current research says about testing, lifestyle strategies, and hormone therapy.
Whether you’re navigating new symptoms or seeking a deeper understanding of your hormonal landscape, this section helps women build clarity and confidence around one of the most essential hormones in midlife health.
