The Biology of Trauma® With Dr. Aimie

You have been doing the work. The therapy, the somatic practices, the self-care. And your body still will not come online.

You have also been doing the gut protocol. Months of it. And the exhaustion has not lifted.

Here is what almost nobody tells you. The thyroid governs gut motility. When it runs low and slow, the bloating and the constipation you have been treating from the gut end may have been downstream of the thyroid the whole time. So you can do everything right, in the right order, and still be working the wrong end of the problem.

This is Part 2 with Dr. Amie Hornaman, known as the Thyroid Fixer. She was misdiagnosed six different times in her twenties before anyone found it.

In this episode she gets practical about selenium, about which system to start with, and about why she thinks adrenal fatigue is overdiagnosed. She also gives a number for how long before your energy and stress resilience actually shift, with the caveat that belongs beside it.

WHAT YOU'LL LEARN: Which to treat first when your gut and thyroid are both struggling How a slow thyroid produces constipation, bloating and SIBO The foundational nutrients she starts everyone on, and why selenium leads Why one morning cortisol reading cannot tell you what you think it does How long before energy, mood and stress resilience begin to move

The full show notes have the research behind the SIBO connection, every quote from the episode, the chapter list, and the optimal lab ranges to ask about.

You have been doing the work. You understand your patterns. And you are still waking up unable to face the day.

When the body decides survival is the priority, it stops converting thyroid hormone into the form your cells can use. It produces an inactive version instead, called reverse T3, and that version blocks the active hormone at the cell door. The result is a body running low and slow. It is the same physiology I call chronic functional freeze.

Dr. Amie Hornaman ranks reverse T3 as the single most important thyroid marker, ahead of free T3, and it is a marker almost nobody orders. She also holds that stress and trauma on their own can raise it.

This is Part 1 of a two part conversation.

WHAT YOU'LL LEARN:

Why a normal TSH does not settle the question of whether your thyroid is involved

What reverse T3 is, and why Dr. Hornaman ranks it above free T3

How stress and trauma can shift thyroid function directly

Why the hibernation state and chronic functional freeze are the same physiology

What happens to the thyroid in the year after an injury or accident

Why you cannot think your way out of a decision the body made below thought

The Thyroid Fix by Dr. Amie Hornaman

Part 2 releases August 20, 2026.

Most trauma has a place you can avoid. Medical trauma lives inside your body, so there is nowhere to go.

Dr. Aimie sits down with Dr. James Jackson for the second half of their conversation on medical trauma. What will surprise you is how much recovery is available while the symptoms are still present.

This is Part 2 of a two part conversation. Part 1 is here.

➡ Full show notes + resources: https://bit.ly/BOT190

Dr. Jackson works with people recovering after critical illness, and he is direct about something most clinicians avoid saying. Patients have been taught that recovery means every symptom is erased. That standard fails most bodies. He offers a different measure, along with the markers that actually move.

Dr. Aimie also shares why she left general surgery residency after four years, and the one question she started asking her patients that changed everything about how she practiced.

 

WHAT YOU'LL LEARN:

02:55 — Why do you carry the source of a medical trauma with you?

05:35 — What is acceptance and commitment therapy?

06:37 — How can you be fine right now?

07:09 — Why did Dr. Aimie leave general surgery residency?

08:17 — What happens when you ask a patient what their diagnosis means to them?

11:40 — Why should no one else decide what counts as a big trauma?

13:33 — Why is overselling recovery a problem?

14:46 — What does a rich recovery actually look like?

15:32 — What are the objective markers that recovery is happening?

17:02 — How should we talk about post-traumatic growth?

20:22 — Why can no one recover from medical trauma alone?

 

"If the trauma happened in your body, you're carrying that around. You're carrying it around, and you can't avoid it. It's always there." — Dr. James Jackson

 

If you have quietly decided you are not recovering because something still hurts, this episode is for you.

A hospital saved your life, and now you plan your route so you do not drive past it. That has a name, and the name is medical trauma. 

Medical trauma is a trauma response that comes from a medical experience. It can follow an ICU stay, a hard surgery, or an emergency C-section. Post-intensive care syndrome, or PICS, describes new or worsened problems in thinking, mood, and physical function after critical illness.

Dr. James Jackson of Vanderbilt co-founded one of the first clinics in the country for survivors of critical illness. He sat on front porches across the South asking people what their life was like after the ICU, and he heard the same story hundreds of times. In this Part 1 conversation with Dr. Aimie, he names the one sign he watches for above all others, why so many doctors have never heard of PICS, and how long recovery actually takes.

A new mom was losing weight without trying. Her heart raced. Waves of panic arrived without warning. Her doctor congratulated her on the weight and offered her something for the anxiety.

Her anxiety had been doing its job the whole time. It was a message from her thyroid.

In Part 2, Dr. Aimie and Dr. Nicole Cain, author of Panic Proof, walk through the last six of the nine body systems that can produce anxiety. Nervous system, endocrine, immune system, depressive, anger, and trauma anxiety. Each one leaves a different signature, and each one asks for something different.

You will hear why anger rises as you come out of chronic functional freeze, and how trauma work shifted one woman's biology down to what showed up on objective testing.

 

In This Episode You'll Learn:

01:00 — What is nervous system anxiety? 

02:53 — Which herb supports a nervous system worn down by stress? 

03:42 — What blood work should I ask for? 

04:37 — How did Charlotte's anxiety turn out to be her thyroid? 

07:17 — What is immune system anxiety? 

08:35 — Why does an antihistamine sometimes settle anxiety? 

09:07 — How does inflammation in the brain create anxiety? 

11:33 — Can my gums be affecting my anxiety? 

13:01 — What is depressive anxiety, and what can an SSRI set off? 

17:07 — What is anger anxiety, and how do I cool it down? 

18:57 — Why am I angrier as I come out of freeze? 

20:36 — Can trauma work change a condition like PCOS?
