24. Histamine & Anxiety – How High Histamine Triggers Fight-or-Flight Symptoms

Ever felt anxious, on edge, or like your nervous system is stuck in overdrive — and wondered if there’s more to it than just stress?

In this episode of *The Histamine Well*, we explore how high histamine levels in the brain can be a major driver of anxiety — especially when it's paired with methylation issues, chronic stress, hormonal imbalances, or gut dysfunction like SIBO and mold exposure.

Joanne breaks down the neurological symptoms of histamine overload, what it means to be an over- or under-methylator, and how everything from estrogen to oxalates and MarCons could be part of the puzzle.

👉 If you've tried therapy, medication, and diet changes but nothing seems to shift your anxiety — this episode might just explain why.

*What You’ll Learn:*

✔ How histamine acts as a neurotransmitter in the brain
✔ The difference between over- and under-methylation — and why both can increase brain histamine
✔ Gut-brain histamine signalling (SIBO, H. pylori, oxalates, gluten)
✔ How estrogen, mold, and chronic stress all play into histamine-driven anxiety
✔ Clinical tools and supplements to start reducing your histamine load
