Do you experience a racing heart when you stand up? Crushing fatigue with no diagnosis? Brain fog, dizziness, or a body that just won't cooperate — and doctors who keep telling you it's just anxiety? You might be dealing with dysautonomia, and you're not alone.

In this third episode of our dysautonomia series, Dr. McMinn and Coach Lindsay sit down with Tyler Mathews — nutritionist, dysautonomia and POTS survivor, and creator of DysautonomiaRecovery.com and ChatDys.com — to explain what's really going on beneath the surface.

Tyler breaks down the immune system's role in dysautonomia: how autoantibodies can hijack autonomic receptors, how viral and bacterial infections trigger the condition through molecular mimicry, and why small fiber neuropathy, leaky gut, and mast cell dysfunction create a vicious self-perpetuating cycle. He also explores the overlooked roles of circadian rhythm disruption, histamine intolerance, and sunlight deficiency.

We dig into the Dysautonomia Trifecta — the well-documented overlap between POTS, Mast Cell Activation Syndrome (MCAS), and hypermobile Ehlers-Danlos Syndrome (hEDS) — and how Long COVID has brought this constellation of conditions into sharper focus for both patients and researchers.

Tyler then shares what actually worked in his own recovery: stabilizing mast cells, repairing gut integrity, restoring mitochondrial function, supporting vagal tone, and resetting circadian rhythms. A root-cause roadmap, not just symptom management.

If you're searching for answers about POTS, MCAS, EDS, Long COVID autonomic dysfunction, or chronic fatigue with no clear diagnosis — this episode was made for you.

Recovery isn't just possible. It has a path. There is hope for a brighter future.
