80: The Hidden Trigger Behind So Many Chronic Illnesses – Understanding Mast Cell Activation with Dr. Aaron Hartman
Description
Could unexplained symptoms like fatigue, flushing, or gut issues actually be signs of Mast Cell Activation Syndrome—the hidden link behind chronic inflammation?
In the final episode of our five-part Mystery Illnesses series, Dr. Aaron Hartman explores Mast Cell Activation Syndrome (MCAS) — a complex and often misunderstood condition. He unpacks the science behind mast cells, their role in immunity, and how dysregulation can lead to multi-system symptoms affecting the skin, gut, respiratory, and nervous systems. Dr. Hartman also examines the overlap between MCAS and other chronic conditions like Lyme disease, mold exposure, autoimmune disorders, and POTS, while addressing the challenges of testing and diagnosis.
This episode provides clarity on how MCAS can manifest in seemingly unrelated symptoms — from flushing and fatigue to anaphylaxis and GI distress — and offers insight into how functional medicine can help identify and treat the root cause.
Key Topics Covered
- Overview of Mast Cell Activation Syndrome (MCAS) as a widespread but often misunderstood condition

- Diagnostic challenges caused by short-lived lab markers and inconsistent testing practices
- How therapeutic trials can aid both management and diagnosis
- Functional and systems-based approaches to treatment, including lifestyle and nutritional interventions
- The connection between MCAS, chronic inflammation, and immune system imbalance
- Overlap with other “mystery illnesses” such as Lyme disease, mold toxicity, autoimmune disorders, and POTS
- Encouragement for listeners to share their own experiences with MCAS and histamine-related issues
