PTSD and Trauma Physiology
Trauma lives in physiology as much as memory. Alongside trauma therapy, we address the stress axis, autonomic balance, inflammation, sleep, and brain networks.
What you may be noticing
You startle at sounds others do not seem to hear. Sleep is broken by vivid dreams. You scan every room for exits. Certain smells or tones pull you back to another moment. Or you feel numb, far away, or exhausted from being on guard for so long. Your posture, breath, and digestion may carry the same tension.
If you are thinking about harming yourself, call or text 988 in the United States, or contact emergency services now. My work is comprehensive physiological support alongside a qualified trauma therapist, never a replacement for that care, and medications are never changed without your prescriber.
Why it is rarely one thing
Post-traumatic stress is not a weakness of character. It is a nervous system that concluded, correctly, that the world was dangerous, and has not yet received enough evidence that it is safe now. Its symptoms are intelligent adaptations.
Trauma reshapes physiology. The amygdala becomes more reactive. The prefrontal cortex, which normally calms the alarm, becomes less effective under stress. The HPA axis and the autonomic system lose their flexibility, swinging between high arousal and shutdown. Inflammation often rises, sleep architecture changes, and the gut feels it too. In my clinical view, experience is also held in the body: in breath patterns, muscle and fascial tension, and protective posture. The body cannot heal what the nervous system does not feel safe enough to process.
Patterns we look for
- HPA axis output: cortisol rhythm and stress reactivity.
- Autonomic balance and vagal tone, including heart rate variability.
- Inflammation and neuroinflammation.
- Sleep architecture and possible sleep apnea.
- Blood sugar instability, which can mimic and amplify panic.
- Gut-brain axis and intestinal permeability.
- Frontal and limbic balance.
- Breathing pattern, posture, and somatic holding patterns.
- Vestibular and eye movement findings, especially when trauma included a head injury.
- Nutrient status that shapes neurotransmitters: B vitamins, magnesium, omega-3, iron, and vitamin D.
How I evaluate it
I work at a pace that feels safe for you. The comprehensive functional neurological exam assesses eye movements, balance, autonomic responses, breathing, and frontal function gently, and it often brings relief to see that symptoms have a measurable physiological basis.
Functional labs may include a cortisol rhythm, a thyroid panel, fasting insulin and glucose, inflammatory markers, ferritin, B12, vitamin D, omega-3 index, and comprehensive stool analysis when the gut is involved. Heart rate variability gives us a living measure of regulation over time. NeuroQuant volumetric MRI is considered when trauma included a head injury.
How we address it
Sequence is everything. Safety comes before depth.
- Coordinate with your trauma therapist and prescribing physician.
- Build safety first: predictable routines, morning light, steady blood sugar, and sleep support.
- Restore vagal tone with humming, extended exhales, gentle pressure, and slow breathing, short practices repeated through the day.
- Reset the limbic system with brain-based rehabilitation for frontal regulation, eye movement, and vestibular balance.
- Release held tension through somatic movement such as qi gong, gentle dance, and bodywork, at your own pace.
- Reduce inflammation, support the gut-brain axis, and rebalance nutrient chemistry.
- Only when the nervous system has a stable floor do we move into deeper emotional integration, together with your therapist.
Your nervous system adapted to survive. With the right support, it can adapt again to feel safe, steady, and free.
