Oestrogen dominance is one of the most common and most misunderstood hormonal imbalances affecting women today. It does not simply mean that oestrogen is high – it means that oestrogen is elevated relative to progesterone, creating an imbalance between the two hormones that drives a wide range of symptoms. It is also one of the most treatable hormonal conditions, once the underlying drivers are properly identified.
At The Naturopathic Co., our naturopaths take a thorough, investigative approach to oestrogen dominance. We look beyond the symptoms to identify what is driving the imbalance – whether that is poor gut clearance, liver dysfunction, stress, nutritional deficiencies, or environmental oestrogen exposure – and we build a treatment plan that addresses the cause. We consult Australia-wide via telehealth and have helped many women significantly reduce their oestrogen dominance symptoms through targeted, evidence-based naturopathic care.
Oestrogen dominance occurs when oestrogen levels are disproportionately high relative to progesterone. This can happen in two ways – oestrogen can be genuinely elevated, or progesterone can be low while oestrogen remains within normal range. In both cases, the result is the same: an oestrogen-to-progesterone ratio that is out of balance and producing symptoms.
Oestrogen dominance is extremely common in the modern world. Environmental oestrogens found in plastics, pesticides, personal care products, and food packaging – known as xenoestrogens – add to the body’s oestrogenic load. Poor diet, chronic stress, excess body fat, impaired liver function, and disrupted gut health all contribute to oestrogen accumulation. Understanding which of these drivers is most significant for you is central to effective treatment.
Oestrogen dominance can manifest across many body systems. Common symptoms include PMS including mood swings, irritability, and anxiety before menstruation, heavy or prolonged periods, bloating and fluid retention, breast tenderness and swelling, hormonal headaches or migraines, weight gain particularly around the hips, thighs, and abdomen, difficulty losing weight, fatigue, brain fog, poor sleep and night sweats, hormonal acne particularly around the jaw and chin, fibroids and endometriomas, and worsening of endometriosis symptoms.
Many women with oestrogen dominance are told their hormone levels are normal on standard blood testing. This is because most GPs test oestrogen at a single point in the cycle, which rarely captures the full picture. Comprehensive saliva hormone testing across the cycle provides a much more accurate assessment – and often reveals the imbalance that standard testing misses.
The most important and most overlooked drivers of oestrogen dominance are poor gut health and impaired liver function. Understanding this connection is key to treating oestrogen dominance effectively.
Oestrogen is processed by the liver and then passed into the gut for elimination. In the gut, a collection of bacteria known as the estrobolome are responsible for metabolising oestrogen so that it can be excreted from the body. When the gut microbiome is disrupted – through dysbiosis, leaky gut, constipation, or SIBO – an enzyme called beta-glucuronidase becomes overactive. This enzyme deconjugates oestrogen that has already been processed for elimination, reactivating it and allowing it to be reabsorbed into the bloodstream rather than excreted.
The result is a cycle of oestrogen recirculation that drives oestrogen dominance regardless of how much oestrogen the body is producing. This is why treating oestrogen dominance without addressing gut health consistently produces limited results. Learn more about our gut health naturopathy.
The liver is equally central. Phase one and phase two liver detoxification pathways are responsible for breaking oestrogen down into safer metabolites before it reaches the gut. When liver function is impaired – through poor diet, alcohol, nutrient deficiencies, or toxic load – oestrogen is not properly metabolised and accumulates in the body. Supporting liver detoxification pathways through targeted nutritional medicine and herbal medicine is a key part of oestrogen dominance treatment.
Low progesterone is both a consequence and a driver of oestrogen dominance. Progesterone is the natural counterbalance to oestrogen – it opposes oestrogen’s proliferative effects, supports mood and sleep, and is essential for a healthy luteal phase. When progesterone is low, oestrogen dominates by default.
The most common causes of low progesterone include chronic stress – which diverts pregnenolone toward cortisol production at the expense of progesterone – poor ovulation, nutritional deficiencies particularly in zinc, B6, and vitamin C, and adrenal dysfunction. Our naturopaths assess progesterone as part of every oestrogen dominance evaluation and support its production where deficiency is identified. Learn more about how stress and adrenal fatigue affect hormonal balance.
Effective treatment of oestrogen dominance requires addressing the full picture – gut health, liver function, progesterone support, stress, nutrition, and environmental oestrogen exposure together. Our approach is personalised to your specific drivers and symptom picture.
Treatment may include gut microbiome support to restore healthy oestrogen clearance and reduce beta-glucuronidase activity, dietary guidance including cruciferous vegetables, fibre, and foods that support oestrogen metabolism and liver detoxification, herbal medicine to support liver detoxification, progesterone balance, and cycle regulation, targeted nutritional medicine including DIM, calcium-d-glucarate, magnesium, B vitamins, and zinc, stress and adrenal support to restore healthy progesterone production, practical guidance on reducing xenoestrogen exposure through diet, personal care products, and household products, and addressing constipation and food sensitivities where these are impairing oestrogen clearance.
Oestrogen dominance is a driver of – or contributor to – many other hormonal and gynaecological conditions. If you have been diagnosed with endometriosis, fibroids, PCOS, or if you experience severe PMS or heavy periods, oestrogen dominance is likely playing a role. Addressing it is rarely a standalone treatment – it is usually one important piece of a broader hormonal treatment plan.

Accurate hormone testing is particularly valuable in oestrogen dominance, as standard GP blood tests often miss the imbalance entirely. Through our functional testing partners, we can assess oestrogen and progesterone across the full cycle using saliva testing, oestrogen metabolites to assess how oestrogen is being processed and cleared, cortisol and adrenal function, gut microbiome health and beta-glucuronidase activity via comprehensive stool analysis, liver detoxification capacity, and nutritional status.
All test kits are shipped directly to your home. Results are reviewed at your follow-up consultation and guide a precise, targeted treatment plan. Learn more about hormone testing options.
