Can Trauma Make Genetic Disease Worse? The Role of the Nervous System

2025-09-30

Many people living with genetic conditions like MEN1, or hereditary autoimmune disorders feel trapped by their diagnosis. Practitioners often monitor and treat symptoms without addressing how trauma and nervous system dysregulation amplify those symptoms. But what if your nervous system still holds the key to how you experience your genetic condition? In this conversation, Lizzie Dunn, diagnosed at 13 with MEN1, shares how she came to my work skeptical about trauma's role in genetic disease. She discovered that her body wasn't betraying her. It was protecting her. And...

In this conversation, Lizzie Dunn, diagnosed at 13 with MEN1, shares how she came to my work skeptical about trauma's role in genetic disease. She discovered that her body wasn't betraying her. It was protecting her. And through nervous system regulation and somatic work, she experienced shifts she never thought possible.

This episode bridges the gap between conventional medicine and trauma healing. Whether you're a practitioner working with genetic conditions or someone living with a hereditary diagnosis, you'll learn how the nervous system acts as the master conductor of your biology.

In this episode you'll hear more about:

[00:00:09] How nervous system regulation influences genetic disease symptoms
[00:03:00] Why the nervous system sees genetic mutations as vulnerabilities that trigger faster trauma responses
[00:09:00] How stored trauma creates dysregulation that amplifies all symptoms
[00:14:00] Why so many people with chronic conditions live disconnected from their bodies
[00:22:00] How paradox and vulnerability are essential parts of healing
[00:23:40] Why generational trauma gets passed down through mitochondrial DNA
[00:30:00] How healing requires working on mind, body, and biology levels simultaneously
[00:36:00] Why small interventions across three areas create bigger shifts than years of single-approach work

Main Takeaways:

Nervous System as Master Conductor: Even with genetic conditions, the nervous system determines symptom severity by directing all physiological responses and biological adaptations
Genetic Vulnerabilities Trigger Faster Trauma Responses: The nervous system sees genetic mutations as vulnerabilities, causing it to move into overwhelm and trauma biology more quickly than if no vulnerabilities existed
Body Disconnection is Survival: Living in your head and disconnecting from your body is a protective mechanism to avoid overwhelming sensations of powerlessness, shame, and pain
Generational Trauma Through DNA: Trauma passes down through mitochondrial DNA on the mother's side via epigenetic changes from oxidative stress, affecting gene expression in future generations
Integration Creates Lasting Change: Single-approach healing (therapy alone, supplements alone, or diet alone) creates temporary shifts; addressing mind, body, and biology simultaneously creates sustainable transformation
Small Hinges Move Big Doors: You don't need decades of intensive work; small interventions across three levels create remarkable shifts when done together
Body Has Innate Healing Capacity: Like skin healing over surgical incisions, the body can reorganize and reset when blocks at mind, body, and biology levels are removed

Notable Quotes:

"Even if we have a truly genetic disease, the nervous system is still going to be influencing the degree of symptoms that we have from that."

"The nervous system is what drives all the other systems, because it's what changes them, allows them to adapt to our environment. And so the nervous system, when it becomes dysregulated in its responses, it's going to cause dysregulation of all the other symptoms and systems."

"Why would I want to be in my body? My body is in pain, emotional pain, physical pain. I don't like my body. My body is working against me. At least that's the thought that I have. Why would I want to be in my body?"

"That's not resilience. That's pushing through, that's surviving. So let's call it that. Let's call it, Hey, you're surviving, you're pushing through. But that kind of resilience is going to come at a cost."

"Epigenetics do get passed down to us, and it gets passed down, especially through the mother because of the mitochondrial DNA that gets passed on to the children."

"You actually don't have to do that much of each to start seeing shifts. But we do need to bring in all three because when you have all three, they're like small hinges. And when you've got small hinges and you've got three of these small, you just did baby steps, small hinges move big doors in our life."

Episode Takeaway:

Living with a genetic condition doesn't mean you're powerless over your symptoms. Your nervous system acts as the master conductor of your biology, determining how severely you experience your hereditary condition. When you have genetic vulnerabilities, your nervous system perceives them as threats and moves into trauma biology faster, creating dysregulation across all systems. The exhaustion many people feel isn't just from their disease—it's amplified by stored trauma, nervous system dysregulation, and the survival mechanism of disconnecting from their body. True healing requires removing blocks at three levels simultaneously: addressing self-limiting beliefs through parts work, completing interrupted protective responses through somatic work, and supporting cellular function through biology interventions. When you provide support across all three levels, small interventions create remarkable shifts. Your body has innate healing capacity—when blocks are removed, it can reorganize, reset, and return to its best possible state, regardless of genetic vulnerabilities.
