Estrogen Dominance

Estrogen dominance is a relative imbalance: estrogen is unopposed by progesterone, either because progesterone is low (anovulatory cycles, perimenopause) or estrogen clearance through the liver and gut is sluggish.

Common symptoms

  • Breast tenderness
  • Heavy or painful periods
  • Fibroids, endometriosis
  • Fluid retention
  • Stubborn fat on hips and thighs
  • PMS, mood swings

What drives it

  • Anovulatory cycles
  • Perimenopause
  • Sluggish liver clearance, poor gut/bowel function
  • Excess body fat
  • Endocrine-disrupting chemicals

Testing approach

We look at the estradiol:progesterone ratio in the luteal phase, plus liver markers and SHBG to understand clearance.

What to do next

  • Support ovulation and progesterone (sleep, fuel, stress)
  • Improve estrogen clearance: cruciferous vegetables, daily bowel movements, alcohol moderation
  • Address insulin and body composition where relevant

Frequently asked

Is estrogen dominance a diagnosis?

Not a formal one — it's a useful descriptive pattern. The underlying drivers (anovulation, perimenopause, clearance) are what we actually treat.
