The Silent Consequences of Low Hormones — What Nobody Told Me About Menopause

This post is based on my personal experience and is for informational purposes only. Please consult your own doctor before making any hormonal or medical decisions.

For years I assumed the way I was feeling was just ageing. The fatigue that wouldn't shift. The weight that crept up despite eating well. The anxiety that arrived out of nowhere. The sleep that stopped being restorative. The inflammation and bloating that became my daily normal.

I was wrong. It wasn't just ageing. It was my hormones — or more accurately, the near complete absence of them.

What the tests revealed

Earlier this year I had a comprehensive hormone panel through an integrative GP. What came back was confronting. Oestrogen almost undetectable. Progesterone very low. Testosterone below measurable range. DHEA low. Cortisol elevated. Early insulin resistance already developing.

This wasn't perimenopause. This was full menopause with pan-hypogonadism — meaning all four key hormones had essentially stopped.

And my body had been quietly paying the price.

What low oestrogen actually does

Most women know oestrogen affects hot flushes. What they don't always know is what sustained low oestrogen does over time.

Bone density begins to decline — oestrogen is protective against osteoporosis and its withdrawal accelerates bone loss significantly. Cardiovascular risk increases — oestrogen has a protective effect on the heart and blood vessels that disappears with menopause. Cognitive function can be affected — brain fog, memory lapses and difficulty concentrating are all documented effects of low oestrogen. Skin thins and loses collagen. Sleep architecture changes. And metabolic function slows, making weight management increasingly difficult despite no change in diet or exercise.

I had most of these symptoms. I just hadn't connected them.

What low progesterone does

Progesterone is the calming hormone. It supports sleep quality, reduces anxiety, and has a natural cortisol lowering effect. When it drops, the impact on the nervous system is significant.

Anxiety that feels disproportionate to circumstances. Sleep that is light and unrestorative. A stress response that feels permanently activated. Mood instability that arrives without obvious cause.

I attributed all of this to my stressful job. Some of it was. But progesterone deficiency was amplifying everything.

What low testosterone does

Testosterone isn't just a male hormone. Women need it too — for energy, muscle strength, motivation, cognitive sharpness and metabolism.

At below measurable levels, the effects are significant. Persistent fatigue that sleep doesn't fix. Muscle loss and difficulty building strength despite exercise. Abdominal weight gain that resists everything. Low motivation and drive. Difficulty concentrating.

I had been weight training three times a week and walking ten thousand steps daily. Then gradually I couldn't. This is why.

What low DHEA does

DHEA supports adrenal function, immune health and overall vitality. It's often overlooked in standard testing — mine was only picked up because I specifically sought a comprehensive integrative panel.

Low DHEA contributes to fatigue, reduced immune resilience and a general sense of depleted vitality that is hard to articulate but impossible to ignore.

The downstream consequences nobody warned me about

The most significant finding beyond the hormones themselves was what the hormone decline had triggered — early insulin resistance and elevated cortisol.

Falling oestrogen and progesterone remove their natural protective effect on insulin sensitivity. Combined with chronically elevated cortisol from stress, this creates a cycle — fatigue, central weight gain, inflammation, blood sugar dysregulation — that compounds itself and becomes increasingly difficult to reverse without addressing the hormonal root cause.

My cholesterol was also elevated. My integrative GP noted this may be connected to subclinical thyroid slowing driven by the hormone changes — another downstream consequence I hadn't anticipated.

What I want other women to know

If you are in your fifties or sixties and something feels persistently wrong — please get a comprehensive hormone panel. Not just TSH. Not just a standard blood test. A full picture including oestrogen, progesterone, testosterone, DHEA, cortisol, fasting insulin and inflammatory markers.

The standard medical conversation around menopause often focuses on hot flushes and mood. The full picture is significantly more complex — and the long term consequences of leaving hormone deficiency unaddressed extend well beyond comfort symptoms into genuine health risk.

You deserve the full picture. Go and get it.
