Quick answer: Estrogen dominance means estrogen is high relative to progesterone, or the body isn’t clearing estrogen well. Diet, stress, excess body fat and environmental chemicals that mimic estrogen (xenoestrogens) such as BPA, phthalates and some parabens can all contribute. Reducing exposures, eating fiber and cruciferous vegetables, and supporting liver and gut health help your body process estrogen.
What is estrogen dominance?
An imbalance where estrogen effects outweigh progesterone, or estrogen is cleared slowly. For the full clinical picture, see estrogen dominance and estrogen metabolism.
Possible symptoms
- Irregular, heavy or painful periods
- PMS, mood swings and bloating
- Breast tenderness
- Weight gain around the hips and thighs
- Fatigue and brain fog
- Fibroids or endometriosis (with medical evaluation)
Understanding estrogen
The three main estrogens are estradiol, estrone and estriol. Levels are regulated by FSH, LH and progesterone. See estradiol.
Causes and risk factors
Diet and gut health
The liver processes estrogen and the gut helps eliminate it. Low fiber and dysbiosis can allow estrogen to be reabsorbed.
Lifestyle
Chronic stress affects progesterone, and body fat produces estrogen.
Environmental exposures
- Bisphenol A (BPA) in some plastics and can linings
- Phthalates in fragrances and soft plastics
- Some parabens in personal care products
- PCBs, PFAS and some pesticides
- Heavy metals such as cadmium
Testing
- Blood estradiol, progesterone and related hormones
- Urine estrogen metabolite tests (functional, optional for 1-on-1 patients)
- Functional labs are optional. They can be helpful in more complex cases, and in my practice they are available only to patients working 1-on-1 with me.
Supportive steps
- Reduce exposure: glass containers, fragrance-free products, filtered water
- Eat cruciferous vegetables, flax and chia seeds, berries and fiber
- Support the liver and gut; limit alcohol
- Supplements such as DIM or calcium D-glucarate and herbs such as chasteberry or black cohosh are sometimes used; discuss with your provider, since they can affect hormones and interact with medications
Healthy aging lens
Hormone-disrupting chemicals interfere with how cells communicate. Lowering exposure and supporting estrogen metabolism helps protect long-term health.
When to see a naturopathic doctor
- Ongoing fatigue, headaches, skin or digestive symptoms
- Known exposure to lead, mercury, mold or workplace chemicals
- You take medications or have liver, kidney or heart conditions and want to try a detox plan
- You are pregnant or breastfeeding (detox protocols are not recommended)
See a medical provider promptly for signs of poisoning such as severe abdominal pain, vomiting, confusion, seizures or trouble breathing, or call Poison Control at 1-800-222-1222.
