Estrogen Dominance

“Estrogen dominance” is a term originally coined by Dr. John Lee in his book What Your Doctor May Not Tell You About Menopause.  In conventional medicine, we would call this “luteal phase insufficiency”.  “Estrogen dominance” is a useful concept when considering the symptoms that can occur with perimenopausal hormonal fluctuations. Symptoms of estrogen dominance include:

  • Hot flashes and night sweats
  • Mood swings
  • Irritability
  • Insomnia
  • Foggy thinking
  • Fatigue
  • Weight gain
  • Decreased libido
  • Worsening PMS
  • Irregular periods
  • Heavy periods
  • Hair loss
  • Bloating

The theory behind estrogen dominance is that during the perimenopausal transition, the ovaries continue to produce normal amounts of estrogen (estradiol) but lower than normal amounts of progesterone, creating an imbalance of hormones.   Since the symptoms of estrogen dominance can be very similar to symptoms of estrogen deficiency, precisely timed blood testing is necessary to make the diagnosis.  If the progesterone level is low, progesterone supplementation can be started, providing excellent relief of symptoms.
