Hormone Replacement Therapy (HRT) Is Not The Enemy

For the right woman, at the right time, Hormone Replacement Therapy (HRT) can be life-changing. It can improve sleep, reduce hot flushes, stabilise mood, protect bone density, and support cognitive health.

I’m not against it.

But here’s the nuance most women are never told:

Taking hormones is one thing.
Metabolising them well is another.

Why Hormone Metabolism Matters – Even on HRT

Whether your hormones are coming from your ovaries or from a patch, gel, capsule or troche – your body still has to process them.

That processing happens through:

• Liver detoxification pathways (Phase I and Phase II)
• Methylation pathways
• Gut clearance mechanisms
• Cortisol balance
• Blood sugar regulation

If these systems are under strain, hormones can behave unpredictably.

This is when I see women say:

“I’m on HRT… so why do I still feel awful?”

Symptoms of Poor Hormone Metabolism in Perimenopause & Menopause

When hormone metabolism is compromised, symptoms can persist – even when hormone levels appear “normal.”

Common patterns I see in clinic include:

1. Breast Tenderness & Fluid Retention – Often linked to sluggish oestrogen clearance and tissue sensitivity.

2. Heavy or Breakthrough Bleeding – Oestrogen may be stimulating tissue excessively if not metabolised efficiently.

3. Migraines – Fluctuating oestrogen + inflammatory metabolites + stress = a perfect storm.

4. Mood Volatility & Anxiety – Poor progesterone signalling and unstable cortisol rhythms can amplify emotional reactivity.

5. Bloating & Digestive Changes – The gut plays a major role in oestrogen clearance. If the microbiome is imbalanced, oestrogen can be reabsorbed.

6. Central Weight Gain – Hormone metabolism does not exist in isolation — insulin resistance and cortisol dysregulation often coexist.

This is not just about “too much” or “too little” hormone.

It’s about how your body is processing what it has.

This Is Where Testing Matters: DUTCH Testing

When symptoms persist or feel disproportionate, I don’t guess. I investigate.

One of the tools I use in clinic to assess hormone metabolism is DUTCH testing (Dried Urine Test for Comprehensive Hormones).

DUTCH testing allows us to look at more than just hormone levels. It helps us assess:

• Oestrogen metabolites (which pathways your oestrogen is favouring)
• Progesterone metabolites
• Testosterone metabolism
• DHEA production
• Free and metabolised cortisol patterns
• Methylation markers involved in hormone clearance

This gives us insight into:

• Whether oestrogen is moving down more protective pathways
• Whether inflammatory metabolites are elevated
• Whether cortisol rhythm is destabilising hormone balance
• Whether adrenal contribution is adequate
• Whether methylation capacity is sufficient

Functional testing doesn’t diagnose disease — it provides context.

And context changes treatment.

Supporting the System – Not Just the Hormone

If hormone metabolism is sluggish, the solution is not always:

“Increase the dose.”

Sometimes the work involves:

• Supporting liver conjugation pathways
• Improving gut microbiome balance
• Stabilising blood sugar
• Reducing inflammatory load
• Repleting key nutrients (B vitamins, magnesium, zinc)
• Regulating cortisol rhythm

When the terrain is supported, hormones – endogenous or prescribed – behave more predictably.

And symptoms often settle.

A More Nuanced Approach to Perimenopause & Menopause

Perimenopause is a stress-sensitive, metabolically demanding transition. It requires:

• Resilient adrenal function
• Stable blood sugar
• Efficient detoxification
• Adequate nutrient status
• Inflammatory control

We don’t treat hormones in isolation. We ask:

• What is happening at a cellular level?
• What is driving this symptom expression?
• Will testing change the treatment plan?

That is where real clarity begins.

If You’re On HRT and Still Symptomatic…

You’re not broken. And you’re not imagining it.

Sometimes what’s missing is not another prescription — it’s a deeper biochemical assessment.

Hormone Replacement Therapy is not the enemy.

But hormone metabolism matters.

And when we support the whole system, this transition becomes far more manageable – and far less chaotic.
