Let’s talk about one of the most common yet often overlooked health issues many women experience—sometimes for years—without realising it: oestrogen dominance.
Understanding Oestrogen Dominance
So many of the symptoms women attribute to “just getting older” or “normal hormonal changes” can actually be linked to this imbalance. To understand why this happens—and what you can do about it—let’s unpack what oestrogen dominance really means.
What Is Oestrogen Dominance (and Relative Oestrogen Dominance)?
When we talk about oestrogen dominance, we’re usually referring to one of two situations:
True oestrogen excess — when your body is producing or absorbing too much oestrogen.
Relative oestrogen dominance — when oestrogen levels are within the normal range but are too high relative to other hormones, such as progesterone.
In both cases, the body feels the effects of “too much oestrogen,” even if the actual hormone levels differ. These imbalances can lead to similar symptoms, which we’ll explore shortly.
It’s important to remember that every woman’s hormonal landscape is unique. If you suspect your hormones are out of balance, working with a qualified healthcare provider is always the safest approach. Sometimes medical support—like hormone therapy—may be necessary.
How Hormones Change Through the Life Cycle
While oestrogen dominance can occur at almost any stage after puberty, it’s most common after age 30.
Here’s why:
Progesterone levels naturally start to decline in your early 30s and drop more rapidly after 35.
Chronic stress can make things worse, as your body uses the same building blocks to produce stress hormones (like cortisol) instead of progesterone.
Oestrogen, on the other hand, tends to decline more slowly—often not dropping sharply until menopause (around age 50–51).
This mismatch between progesterone and oestrogen creates the “dominance” effect.
Exposure to hormone disruptors—like chemicals in plastics, pesticides, and cosmetics—can also contribute to oestrogen excess earlier in life.
Common Signs of Oestrogen Dominance
You might be experiencing oestrogen dominance if you notice:
PMS or irregular cycles
Bloating and water retention
Weight gain, especially around the hips or belly
Fatigue and low mood
Breast tenderness or fibrocystic breasts
Endometriosis or fibroids
Irritability or “brain fog”
These symptoms can make you feel sluggish, unmotivated, and out of balance—but the good news is, there are natural ways to restore harmony.
What You Can Do: Steps Toward Hormonal Balance
Get your hormones tested.
A blood test can help you identify whether oestrogen or progesterone levels are out of sync. If progesterone is low, managing stress and supporting adrenal health can help. In some cases, your healthcare provider may recommend bioidentical progesterone or herbal alternatives.Support your body’s detox pathways.
Reducing your exposure to oestrogenic substances (like BPA plastics and chemical-laden cosmetics) is key. Support your liver and kidneys by eating plenty of cruciferous vegetables (broccoli, kale, cauliflower), drinking detoxifying herbal teas like milk thistle and dandelion, and getting regular exercise or using infrared saunas to promote sweating.Check your cholesterol levels.
Cholesterol often gets a bad rap, but it’s the foundation for hormone production. If your cholesterol is too low, your body may struggle to make enough progesterone.
The Takeaway
Oestrogen dominance doesn’t happen overnight—and it’s not something you have to simply “live with.” By tuning into your body, making smart lifestyle changes, and getting the right medical support, you can bring your hormones back into balance and reclaim your energy, clarity, and sense of wellbeing.
