Studies of children adopted before age two, who have no conscious memory of the event, reveal they have less diverse and more inflammatory gut bacteria years later. This proves the body "keeps the score" of traumatic events, embedding the stress response into our physiology and impacting long-term health.

Unhealed trauma keeps the body's sympathetic nervous system in a constant state of "fight or flight." This chronic stress continuously weakens the gut microbiome and immune system, undermining any benefits from healthy eating, exercise, or sleep. Healing trauma is therefore a prerequisite for physical healing.
The body stores trauma even from before conscious memories form. Such events can restructure the brain's fear center (the amygdala), locking a person into a perpetual "fight or flight" state. This chronic stress response directly damages the gut barrier, leading to lifelong inflammation and digestive disorders.
The gut microbiome exists in a stable state with a resilience that makes it difficult to alter permanently. After short-term disruptions like antibiotics or diet changes, it often 'snaps back' to its original composition. This means meaningful, long-term change requires sustained effort to establish a new, stable microbial state rather than temporary interventions.
According to neuroanatomist Dr. Jill Bolte-Taylor, the brain's left emotional system stores past pain, trauma, and addiction. This isn't a flaw; it's a protective mechanism designed to trigger reactions based on past negative events. Healing involves understanding this system, not erasing it.
Contrary to popular belief, intuition isn't just a "gut feeling" or brain pattern. Research, particularly from trauma studies like "The Body Keeps the Score," shows that wisdom and life patterns are physically embedded in the body's fascia and musculature.
The evolutionary "fight or flight" response floods the body with hormones like cortisol to handle immediate threats. This life-saving mechanism comes at a cost: it diverts resources away from non-essential functions like digestion. Chronic stress therefore leads to a chronically sacrificed and weakened gut.
The physical panic experienced before a difficult conversation isn't irrational. It's often a deeply ingrained survival response from childhood, where expressing a need or boundary led to a caregiver's emotional or physical withdrawal. The body remembers this abandonment as a threat to survival.
While you inherit a small fraction of your genetics from your parents, the vast majority of your genetic material comes from the 38 trillion microorganisms in your gut. This microbial DNA is dynamic and shaped by your environment and lifestyle choices, giving you significant influence over your genetic expression.
Early negative experiences, such as parental abuse, cause children to internalize blame. This creates a deeply ingrained subconscious program that they are inherently flawed, which dictates their reactions and self-perception for decades until it is consciously unraveled.
The first three years of life represent a critical window where a child's microbiome develops into its adult-like state. Factors during this period—such as C-sections, antibiotic use, and bottle-feeding—can have a lasting impact on future risk for allergic, autoimmune, and metabolic diseases.
