In this in-depth episode of The Histamine Well Podcast, I explore one of the most overlooked drivers of anxiety in women—blood sugar instability—and why symptoms often persist despite normal lab results. Drawing on clinical observation and biochemistry, I explain how fluctuations in blood glucose can activate the body’s stress response, disrupt hormonal balance, and contribute to ongoing nervous system dysregulation.

You’ll learn a clear, practical breakdown of how blood sugar spikes and crashes trigger cortisol and adrenaline, why standard markers such as fasting glucose and HbA1c may fail to detect instability, and how these patterns can mimic symptoms of anxiety disorders. Joanne also outlines the role of nutrition—particularly protein intake—in stabilising blood sugar, supporting neurotransmitter production, and improving overall resilience.

This episode provides a structured framework for understanding how dietary patterns, lifestyle habits, and physiological stress interact to drive both physical and emotional symptoms. Joanne also connects the dots between blood sugar regulation, histamine activity, gut health, and hormone function—highlighting why these systems cannot be viewed in isolation.

Ideal for practitioners, health coaches, and individuals seeking a deeper understanding of anxiety, mood instability, and metabolic health, this episode offers practical insights into addressing one of the most common yet under-recognised contributors to chronic symptoms.
