#9 Histamine Overload and Mast Cells: The Root of Allergy & Congestion

#10 Nervous System Dysregulation: The Root of Inflammation & Hormone Imbalance?

In this episode, Stacy explains the connection between the immune system, nervous system, and endocrine system through the lens of psychoneuroimmunology. You’ll learn how chronic stress impacts cortisol signaling, sympathetic activation, vagal tone, inflammation, histamine symptoms, hormones, and CBC patterns like NLR and LMR. If you work with clients dealing with chronic inflammation, histamine intolerance, hormone symptoms, recurring infections, or autoimmune tendencies, this episode gives you a clearer framework for connecting stress physiology to immune function.

#9 Histamine Overload and Mast Cells: The Root of Allergy & Congestion

Why do some patients seem to react to everything? In this episode of In Good Health, I break down the immunology behind histamine overload, mast cell reactivity, chronic congestion, hives, flushing, gut permeability, and why these symptoms are often more connected than they appear. We’ll also cover how to use the CBC more strategically by looking at eosinophils, basophils, and key ratios like neutrophil-to-lymphocyte and lymphocyte-to-monocyte to guide root-cause thinking and next steps.

#8 Innate Immune System Explained (Using Your Bloodwork)

In this episode of In Good Health, we break down the innate immune system through the lens of a complete blood count (CBC), one of the most underutilized clinical tools in practice. You’ll learn how to interpret key immune cells including neutrophils, monocytes, eosinophils, basophils, and more, not just individually, but as patterns that reveal what the immune system is actually doing. We also connect immune activity to: * Chronic stress and cortisol * Oxidative stress and mitochondrial dysfunction * Allergies, histamine, and hypersensitivity * Autoimmunity (including early Th17 connections) * Cancer and viral surveillance via natural killer cells This episode is especially helpful for practitioners, students, and curious learners who want to better understand CBC patterns, immune balance, and how chronic inflammation can develop from upstream cellular dysfunction. ⁠Click here to Access the CBC Reference Guide [subscrsubscribepage.io/CBCreferenceguideibepage.io/CBCreferenceguide]⁠ Stacy Seslowsky, RD, LDN, MS is now accepting new patients.

#7 What Your CBC Reveals About Inflammation and Immune Balance

In this episode, I explain how inflammation progresses after NF-kappa B signaling increases inflammatory cytokines like IL-6, TNF-alpha, and IL-1 beta. I break down the differences between the innate and adaptive immune system. You will learn how cells like neutrophils, monocytes, eosinophils, basophils, macrophages, dendritic cells act as the first responders, and how antigen presentation bridges into the adaptive immune response, and how immune memory is formed.

#6 Heart Disease Starts With Inflammation (Not Cholesterol)

Heart disease may not begin with cholesterol, but with dysfunction at the cellular level. In this episode, we explore how mitochondrial dysfunction drives oxidative stress, immune activation, and the earliest stages of plaque formation in the arterial wall. Understanding this sequence shifts our focus from symptom management to identifying and addressing root cause. Stacy Seslowsky, RD, LDN, MS is now accepting new patients.
