Can Early Life Stress Show Up in My Gut? Dr. Emeran Mayer

A hard start in life can still be shaping your gut decades later.What will surprise you is that your gut microbes can sense when you are stressed, and they change how they treat your gut wall.➡ Full show notes + resourcesDr. Aimie speaks with Dr. Emeran Mayer, gastroenterologist, neuroscientist and Distinguished Research Professor at UCLA, about how early life stress reaches the gut, the immune system and the brain. He explains increased stress responsiveness, his term for how a difficult birth or childhood becomes biology, and why it does not mean you are doomed.They also talk about why brain fog may start in the gut, the mucus layer that protects the gut wall, and the foods that help it, from diverse fiber to fermented foods.WHAT YOU'LL LEARN:00:00 – 00:38  Introduction00:38 – 02:44  The First 1,000 Days02:44 – 06:31  Early Stress Doesn't Mean You're Doomed06:31 – 08:44  Hard Births and Stress Responsiveness08:44 – 10:56  How Early Stress Shows Up in the Gut10:56 – 14:27  Your Gut Microbes Can Sense Stress14:27 – 17:28  From Gut to Brain: LPS and Brain Fog17:28 – 19:17  The Gut's Protective Mucus Layer19:17 – 21:42  The Interconnected Plate21:42 – 24:01  Why Food Diversity Matters24:01 – 26:46  Foods That Protect the Mucus Layer26:46 – 30:13  Dr. Mayer's Key Message30:13 – 31:12  Closing Reflection and Stress or Trauma Guide"When a gut microbe is exposed to the stress hormone norepinephrine, it changes its genes and becomes more aggressive toward the bowel wall." ~ Dr. Emeran MayerIf you had a difficult birth or a stressful childhood and have lived with gut symptoms or brain fog for years, this episode is for you.RESOURCES:Get the free Stress or Trauma Guide and learn the physical difference between a stress response and a trauma response in under two minutes.Get The Biology of Trauma book.

You want to find the cause and get rid of it.What will surprise you is that the most common place people start, binders, chelation or a mold detox, may be the very thing that makes a reactive body worse.This is Part 2 of a two-part conversation. Part 1 is here: Apple · Spotify · show notes.Dr. Aimie and Dr. Bruce Hoffman talk about where to start when the body reacts to everything. Dr. Hoffman shares the order he used for 30 years with his most complex patients: safety first, then daylight and natural rhythms, self-regulation, POTS, and then calming the mast cells, with binders, chelation and mold treatment much later.They also cover which medications calm mast cells, why supplements alone rarely do, how to tell a Herxheimer reaction from a mast cell reaction, and why mast cell labs so often come back normal.WHAT YOU'LL LEARN:00:00 Where do you start when your body reacts to everything?02:57 Why does safety come first for highly reactive patients?04:03 What are the health cycle principles?06:48 What order did Dr. Hoffman use with his most complex patients?08:11 How do you stabilize mast cells beyond histamine?10:50 Can supplements stabilize mast cells?12:45 Why not start with binders or antibiotics?16:19 Herxheimer or mast cell reaction: how can you tell?19:29 What is a therapeutic trial?21:11 Why wait 3 to 6 months before chelation?"I never approached the toxic load until I've got them stabilized in the health cycle principles, self-regulation, POTS, and mast cells." — Dr. Bruce HoffmanIf you have tried detox after detox and your body only gets more reactive, this episode is for you.RESOURCES:Get the free Companion Guide to Mast Cell Reactivity.

Your labs keep coming back acceptable. Your symptoms keep getting harder to hold. And you have probably landed on one of two conclusions: either something is wrong with you that nobody has found yet, or something is wrong with how you are handling it.I want to offer a third.Full show notes Three things change at the same time in this decade, and each one is invisible on its own.Your immune baseline was set decades before perimenopause. Estrogen, which your immune system has been reading as an instruction every day for years, stops declining in a straight line and starts swinging. And cortisol, which is one of the most powerful anti-inflammatory signals your body makes, stops being received even while your body is producing more of it.That third one is why a normal lab result can be a false negative. The all clear is being sent. It is not landing.In this episode I walk through all three, and I translate the research into language you can use with your own provider. I also tell you why I stopped calculating ACE scores, what a hazard ratio actually means when you read one about your own health, and what has to be stabilized before anything else will hold.Perimenopause does not create the autoimmunity. It does not create the pattern either. It removes the margin that had been holding that pattern quietly, which is why it feels like it arrived out of nowhere.In this episode:Why a cortisol test can read normal while inflammation gets worseThe four immune control points estrogen sits atWhy unpredictable estrogen costs more than declining estrogenWhat "seventy percent increased risk" really meansWhy I stopped calculating ACE scoresWhat has to come first, and why most people start at the wrong endResources:Take the free 2-Minute Assessment for Stored Trauma: https://biologyoftrauma.scoreapp.com/?utm_source=podcast&utm_medium=podcast_audio&utm_campaign=ep195-autoimmunity-perimenopause&utm_content=show-notesThe Biology of Trauma by Dr. Aimie Apigian: https://www.amazon.com/dp/1637746237?tag=draimie-20Full show notes: https://www.biologyoftrauma.com/post/episode-195-why-autoimmune-symptoms-get-worse-in-perimenopauseFull show notes  Grab your copy of The Biology of Trauma

I do not ask about your past. I do not get out the checklist of adverse childhood experiences. I am not calculating your ACE score. And I know how strange that sounds coming from a physician who works with stored trauma.Full show notesWhat I look at is the impact of your past on your today, because that is where it is still leaving its footprint.In this episode I walk you through the assessment I teach practitioners, so you can run it on yourself. Three domains, one repeating pattern, and the equation that decides whether a stressor stays a stress or tips you into overwhelm.Then I take you to the part that surprises people most. Trauma work runs on energy. If your body does not have the capacity, the work cannot integrate no matter how willing you are. Which means the most useful place to start is sometimes sleep, or brain inflammation, rather than the trauma itself. That is still trauma work.I also tell you about the pattern I carried for thirty years, and how it changed without me ever going looking for the reason.In this episode:Why the word trauma gets in the way of finding traumaThe three domains I ask about, and the one pattern that runs through all of themYour capacity against your stress load, and what happens when capacity is smallWhere stress ends and overwhelm beginsWhy perimenopause costs more capacity than most women expectThe nervous system dashboard, and the three things that feed itWhy I sometimes tell someone not to do the trauma work yetHow to find your biggest block without handing yourself the whole listFind your pattern: Take the free 2-Minute Assessment for Stored Trauma The book: The Biology of Trauma by Dr. Aimie ApigianFull show notesThis podcast is educational and is not medical advice.

Your labs confirmed the autoimmune diagnosis. The hardest symptom turned out to be the one nobody prepared you for. Dr. Aimie goes solo on depression and autoimmunity, and which one actually comes first. The answer is less orderly than the one most people are given, and it changes what to do about it. ➡️ Full show notes and research: CLICK HERE Most people are told depression is a reasonable response to being ill. Dr. Aimie interrupts that conclusion with what the research shows: each condition carries close to double the risk of the other, depression turns up in the two years before a diagnosis is made, and roughly a quarter of the link between early adversity and autoimmune disease appears to travel through mental health on the way. She also walks through why this depression rarely feels like sadness, and why the medication may have underperformed. She was on two of them herself, and the hardest part was not the depression. WHAT YOU'LL LEARN: 0:00 The hardest symptom of an autoimmune diagnosis 02:41 — Why is depression treated as the reasonable response to a diagnosis? 04:49 — What does double the risk actually mean for you? 07:58 — What is a dose-response pattern and why does it matter? 09:45 — Where does the childhood adversity evidence stop? 12:19 — What does it mean that depression mediates part of the link? 13:54 — What happens when your cells stop responding to cortisol? 15:55 — Why does this feel like the flu rather than sadness? 20:48 — Why has working on your thoughts not moved it? 22:55 — Why do antidepressants underperform here? 24:54 — What does the infliximab trial actually prove? 28:48 — Where do you start when both are running? "Depression is part of the road from I was healthy to I now have an autoimmune diagnosis." — Dr. Aimie Apigian If the antidepressant did not do much and you quietly concluded something was wrong with you, this episode is for you.

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.
