Dysautonomia – Autonomic nervous system stuck in crisis mode are unable to regulate heart rate, blood pressure, digestion, temperature
Mitochondrial Dysfunction – Cellular energy production impaired can trigger profound fatigue even when nutrient levels are normal
Endothelial Damage & Microclots – Microscopic clots can restrict oxygen delivery; standard clotting tests miss these entirely
Gut Dysbiosis – Microbiome imbalance can disrupt the gut-brain axis, serotonin production, and immune function giving birth to symptoms that seem unrelated.
Hormone Imbalance – Persistent inflammation affecting nervous tissue, driving brain fog and cognitive symptoms
Mast Cell Activation – Immune cells releasing inflammatory chemicals inappropriately, causing allergic-type reactions without actual allergens
These mechanisms interact with gut dysbiosis affecting autonomic function, impairing mitochondrial efficiency, contributing to inflammation.
This is why you have cardiac AND neurological AND GI symptoms simultaneously.
