The Hormone Solution | Perimenopause, Menopause, HRT, Weight Loss & Women's Midlife Health

In this Hormone Hotline episode, I’m answering a powerful question about estrogen HRT, histamine intolerance, and mast cell activation during perimenopause and long COVID.

More Episodes

I share my own long battle with histamine hives, food reactions, and hormone swings—and what finally moved the needle. Why do so many women get worse on a low histamine diet over time? Could unstable estrogen levels be more triggering than estrogen itself? And what role does progesterone really play in calming mast cells?

We also dive into the nervous system piece that almost no one talks about. Is long COVID keeping your body stuck in fight-or-flight? Could therapies like stellate ganglion block, NAD, low-dose naltrexone, GLP-1s, or specific peptides actually reset immune overreactions? And how do you introduce hormones when you’re sensitive to everything?

In this episode, we uncover:

How estrogen fluctuations can trigger histamine and mast cell flares.
Why progesterone may calm both anxiety and histamine symptoms.
role the nervous system plays in long COVID and MCAS.
How peptides and GLP-1 medications may reduce inflammatory signalling.
Why micro-dosing hormones can be safer for sensitive women.

Press play and let’s unpack what might really be driving your symptoms, and what you can do about it!
