What is estrogen dominance?

Estrogen dominance describes a relative imbalance where estrogen levels are high compared to progesterone, rather than an absolute excess of estrogen. This can happen during perimenopause when progesterone often declines faster than estrogen.

Possible signs include heavier or more frequent periods, breast tenderness, bloating, and mood changes. A hormone panel can help clarify whether this pattern is contributing to your symptoms.
