A very interesting - and often
under-recognised - cause of unexplained vertigo can be linked to oestrogen and histamine imbalance, especially in women, including during pregnancy.
A major clue is when vertigo occurs around ovulation or the premenstrual phase – both times of natural oestrogen surges.
Elevated oestrogen can trigger histamine release, setting off symptoms in sensitive individuals. I see this pattern often in clinic.
Once more serious causes (e.g. posterior stroke, MS, Meniere’s) are ruled out, supporting oestrogen and histamine metabolism often brings real relief.
Possible mechanisms behind this connection:
🧠Oestrogen receptors in the inner ear may increase vertigo susceptibility during hormonal shifts.
🧠Pregnancy-related fluid changes can affect the inner ear.
🧠Premenstrual oestrogen surges may promote water retention, impacting ear pressure and balance.
🧠Rapid hormonal changes may disrupt blood sugar and affect brain function, contributing to dizziness.
🧠Histamine-sensitive neurons in the hypothalamus regulate balance and spatial awareness.
Histamine is essential for alertness, stress sensing, learning, and motivation—but in excess, it can cause anxiety, insomnia, vertigo, nausea, and reduced appetite.
This is why antihistamines like Seliforant, Dramamine, and Benadryl are often used for vertigo.
Women are more prone to histamine issues than men, partly because:
✨ Oestrogen increases histamine release
✨ Histamine boosts oestrogen production – a self-perpetuating cycle.
When detox of oestrogen and histamine is impaired – something I see in those with PMS, endo, fibroids, and heavy periods – both can stay elevated and fuel symptoms like vertigo.
