113: Histamine Intolerance or Histamine Overload? Root Causes of Chronic Hives With Jennifer Fugo

In this episode of Thyroid Pharmacist Healing Conversations, Dr. Izabella Wentz interviews Jennifer Fugo, a clinical nutritionist, host of The Healthy Skin Show podcast, and an expert in uncovering the root causes of chronic skin conditions like eczema, chronic hives, dermatographia, and histamine-related symptoms. Jennifer explains why she believes many people have been given an incomplete explanation of histamine intolerance, introducing the concept of "histamine overload" and exploring what may actually be driving symptoms such as chronic hives, itching, flushing, food reactions, headaches, and other histamine-related issues. Together, they discuss the surprising gut infections that may overstimulate mast cells, why restrictive low-histamine diets often fail to address the real problem, the limitations of stool testing, the role of mold and mycotoxins in fueling histamine overload, and the evidence-informed supplements, probiotics, liver support, and medications Jennifer uses to help stabilize mast cells and support long-term healing. In this episode you’ll learn: Why histamine may not be your real problem. Jennifer explains why she prefers the term "histamine overload" and reveals the hidden triggers, including gut infections and mold, that may be driving skin symptoms like hives. The surprising gut bugs that may be keeping your hives from healing. Jennifer explains how H. pylori, Blastocystis hominis, parasites, fungal overgrowth, and other hidden infections may overstimulate mast cells and keep chronic skin symptoms coming back. Why eliminating more foods may actually backfire. Jennifer explains why a low-histamine diet can be a helpful short-term tool, but being on overly-restrictive diets without addressing the root cause can leave people too fearful of food. It is possible to enjoy food again and expand your diet once the root cause is addressed. Why testing doesn't always tell the whole story. Jennifer explains why stool tests can miss hidden infections, what blood work and symptoms can reveal, and why clinical detective work is often just as important as lab results. Could mold be making you react to everything? Jennifer explains how mold exposure and mycotoxins can destabilize mast cells, fuel histamine overload, and even make you unusually sensitive to supplements, food, and environmental triggers. How to naturally support histamine balance. Jennifer shares the nutrients, probiotics, liver support, and other strategies she uses to stabilize mast cells, reduce histamine overload, and help people expand their diets, regain confidence around food, and get back to living their lives. Tune in to learn why histamine may not be your real problem, and how identifying hidden root causes could help you finally move beyond chronic hives, food reactions, and persistent histamine symptoms.
