You've probably seen "estrogen dominance" blamed for all manner of symptoms online. Here's the honest version — what's real, and what's marketing.

The real idea. Oestrogen and progesterone work as a pair across your cycle. "Estrogen dominance" usually refers not to sky-high oestrogen, but to oestrogen being relatively high compared with progesterone — most often because progesterone is low. This commonly happens in cycles where you don't ovulate (since progesterone is produced after ovulation), and in early perimenopause, when progesterone often dips before oestrogen does. A relative shortfall of calming progesterone can contribute to symptoms like heavier periods, breast tenderness, bloating, irritability, and poorer sleep.

The myths to be wary of:

• "Detox your estrogen." You can't flush hormones out with a tea or a cleanse. Your liver and gut already process oestrogen; supporting them with fibre and a healthy gut is sensible, but no product "detoxes" hormones.
• "It's the cause of everything." Many symptoms blamed on estrogen dominance have other explanations (thyroid, stress, perimenopause generally). It's one possible piece, not a universal answer.
• "You can diagnose it from a single blood test." Hormones swing across the cycle; a one-off level rarely tells the whole story.

What helps the oestrogen–progesterone balance:

• Supporting ovulation and overall cycle health (sleep, stress, nourishment, movement)
• A fibre-rich diet and healthy gut (your gut bacteria help process oestrogen)
• Getting a proper assessment for persistent symptoms rather than self-diagnosing online

The takeaway. The balance between your hormones matters — but "estrogen dominance" is a loose, often-misused label, not a tidy diagnosis with a supplement cure. Treat the hype with healthy scepticism.

Common questions

Is estrogen dominance a real medical diagnosis?

It's a popular concept describing oestrogen being high relative to progesterone, but it's not a precise clinical diagnosis. Persistent symptoms deserve a proper assessment.

Can you "detox" excess estrogen?

No — no tea, supplement, or cleanse flushes out hormones. Fibre and a healthy gut support normal oestrogen processing, but that's the extent of it.
