Oestrogen dominance describes one of the most common hormonal patterns affecting women in their 30s, 40s and beyond, yet it is rarely discussed in mainstream medical consultations. Understanding what it is, what drives it, and what can be done about it is an important step towards hormonal health.
The condition is fundamentally about ratio rather than absolute levels. A woman can have oestrogen levels within the “normal” lab reference range and still be oestrogen dominant if her progesterone is disproportionately low. This relative imbalance produces a characteristic cluster of symptoms many women recognise immediately: heavy, painful periods with clots; breast tenderness that worsens before menstruation; stubborn weight gain around the hips and abdomen; severe PMS with mood swings; and difficulty sleeping, particularly waking in the early hours.
The environmental dimension of oestrogen dominance is increasingly recognised as significant. Xenoestrogens — chemicals that mimic oestrogen — are found in plastics (particularly BPA and phthalates), pesticide residues, personal care products containing parabens, and some pharmaceutical medications. Reducing exposure, while impractical to eliminate entirely, is a meaningful adjunct to other interventions.
The liver’s role in oestrogen metabolism is critical and often overlooked. When liver detoxification is impaired — due to excess alcohol, nutrient deficiencies or fatty liver disease — oestrogens recirculate rather than being cleared. Supporting liver function through cruciferous vegetables, DIM supplementation, adequate B vitamins and reduced alcohol intake is a cornerstone of management. HealthLab connects South African women with practitioners experienced in identifying and treating this often-overlooked imbalance.
