Can Childhood Trauma Cause Autoimmune Disease? ACE Scores, Cortisol Burnout, and the Vagus Nerve
Episode Summary
This episode explores the mind-body connection and its role in chronic illness, with Colin Renaud (DC, PA-C) explaining how unresolved trauma and chronic stress create measurable physiological damage. The conversation covers how the autonomic nervous system responds to traumatic events, how that response leads to hormonal dysregulation (particularly cortisol), and why conventional medicine consistently misses the connection. A real patient case study involving sexual trauma and complex chronic illness is discussed, and the episode closes with practical recovery strategies including nutrition, cortisol testing, grounding, and nervous system healing.

Quotable Moments
“Trauma and the mind-body connection is not a psychological experience. It's really a physiological imprint.”
“When you experience chronic stressors or a really significant traumatic event, through neuroplasticity, the brain circuitry starts to rewire. You become a person that has a very heightened threat perception. Every little thing becomes a big thing.”
“A lot of patients that struggle with trauma as a physical manifestation of their health concerns are scooted around from specialist to specialist. A lot of times they end up on psychiatric medications, or they're disbelieved, a lot of gaslighting. It's all in your head.”
“There's no pill to treat trauma. So who's doing that work in the mainstream medical system?”
“The end game of someone that's gone through something like this is burnout. They've just run the body ragged. No gas left in the tank. They're barely functioning. They barely eat. They're experiencing very little joy.”

FAQ
Chronic Illness FAQ
Research using ACE (Adverse Childhood Experience) scores shows that higher tallies of childhood traumas correlate with significantly higher rates of autoimmune disease, substance abuse, and depression in adulthood. The chronic fight-or-flight response creates measurable physiological damage.
The vagus nerve directly innervates the gut. Chronic sympathetic overdrive reduces stomach acid, digestive enzymes, and bile production, causing altered motility and microbiome shifts toward inflammatory bacteria. Most GI doctors never ask about trauma or stress as the root cause.
Cortisol burnout occurs when long-standing stress depletes the adrenals. Cortisol goes from chronically high to chronically low, resulting in inability to get out of bed, needing excessive caffeine, blood sugar instability, and severe fatigue.
Blood cortisol provides a single snapshot. Salivary cortisol maps the full daily curve with samples at multiple points, showing whether cortisol spikes in the morning and drops at night. Med Matrix tests baseline cortisol on all new patients.
Neuroplasticity is the brain's ability to rewire based on experiences. After chronic stress, the brain rewires toward heightened threat perception where every small stressor becomes major. Hypervigilant areas become overactive while calm reasoning areas shrink.
Improving nutrition, optimizing vitamin D, establishing consistent sleep, practicing meditation and journaling, getting morning sunlight and grounding, and working with specialized trauma therapists all contribute. The foundation is removing the stressor and providing basic fuel for recovery.
