One of the biggest hormonal changes during perimenopause isn’t just declining oestrogen… it’s declining progesterone!
And it’s something that doesn’t get talked about nearly enough!
As we enter perimenopause, ovulation can become less consistent, meaning progesterone production starts to decline while oestrogen continues to fluctuate.
This can contribute to:
❌ Increased anxiety and irritability
❌ Poor sleep and waking during the night
❌ Heavier, more irregular periods
❌ Worsening PMS symptoms
❌ Breast tenderness and bloating
❌ Mood swings and feeling overwhelmed
And here’s what many women don’t realise…
You can experience significant perimenopausal symptoms even when your oestrogen levels aren’t low!
Progesterone plays an important role in the menstrual cycle, and changes in its production can have a huge impact on how you feel.
This is why understanding your hormones, ovulation patterns and overall health is so important, rather than focusing on oestrogen alone.
