You were told estrogen is just a “sex hormone.” That’s not even half the story.
plays a major role in regulating inflammation, balancing the immune system, protecting cartilage and bones, maintaining muscle strength, supporting brain function, and helping protect the heart.
When begins and estrogen levels drop, that protection declines. Inflammation can increase. Joint degeneration may accelerate. Bone density decreases. Muscle mass weakens. Brain fog becomes more noticeable.
Research shows that women who experience later menopause — or who begin hormone replacement therapy (HRT) at the appropriate time — may have better joint protection, stronger bones, and improved muscle preservation. This is especially important for women living with arthritis or autoimmune diseases like rheumatoid arthritis or lupus.
Hormone therapy is not one-size-fits-all, but understanding estrogen’s role in immune and musculoskeletal health is critical during perimenopause and menopause.
