Why Gut Issues Are Often Nervous System Issues

Ever eaten the exact same meal twice and had a completely different reaction each time? That's not random and probably not just the food.

Your nervous system is the master controller of digestion. When it's in threat mode, gut function becomes optional. Stomach acid drops. Enzymes drop. Motility goes haywire. And no amount of probiotics fixes a nervous system that doesn't feel safe.

In this episode we cover:

• Why digestion shuts down under stress
• How your nervous system state determines whether food digests smoothly or causes symptoms
• Why food sensitivities are often contextual, not fixed
• Why gut protocols fail when the nervous system piece gets skipped

If you've been doing all the gut things and still not seeing results... this is probably why.

Hello and welcome back to Rooted Conversations. I'm Mackenzie Grace, and today we're getting into something that I genuinely think is a very overlooked piece of gut health. And I do think that once we get into it, it's gonna reframe a lot of things for you. So today we're gonna talk about the nervous system and specifically why your gut issues are and can be very connected to your nervous system. By bloating, acid reflux, and food sensitivities that seem to come out of what seems like nowhere might be actually your nervous system talking and not just a gut health issue. So this one's gonna be short, sharp, and I promise it's gonna make a lot of things click. So let's dive into it. I want to start with a scenario, and I want you to sit with this one for a second because I know at least some of you are gonna recognize yourselves in it. You eat a meal, it's fine. Maybe it's something that you actually eat all of the time: chicken, rice, and some veg, whatever your normal go-to is, and you totally feel fine. Then a few days later, you eat the exact same thing, same ingredients, same portion, same time of the day. And this time you are bloated, like uncomfortable, questioning every single bite. And maybe you're running through a mental list of what you did differently, what you could have could have caused it, whether you suddenly developed a nude food sensitivity because it's the same food, same meal, but you are dealing with a completely different digestion signal. The question is that nobody asks why. Not what food is the problem, but why does the same food cause a different reaction? Because if it were purely always about the food, then it would be consistent. You would have the same reaction the same way every single time, but it doesn't, because digestion is not just about food. Digestion is actually controlled by your nervous system. So what you need to understand at a fundamental level is that your body will only digest when it's actually in rest and digest. This is not a metaphor, this is actual physiology. So our nervous system has two modes rest and digest or fight or flight, are parasympathetic or are sympathetic. And your nervous system is constantly running a background assessment of your environment, your stress load, and your perceived safety. So when it senses threat, whether that's like a real physical stress, threat, a work deadline, a hard conversation, a terrible night of sleep, or just that load grade chronic stress hum that so many of us are operating under, digestion actually becomes optional, not important, but optional. And so when your body is in this nervous system of fight or flight where it's perceiving threat, then what's happening at a biological level is that your body is moving blood flow away from your digestive organs and towards your muscles and your brain. You know, in case you need to run from that bear that your body thinks that it's under. So stomach acid production decreases, digestive enzyme drops, bile flow slows down, and gut motility, so your ability to move through food through your digestive tract becomes erratic. And erratic motility looks like maybe things moving too fast, which is diarrhea, or things moving too slow, which is constipation, or this chaotic, unpredictable mix of both that leaves you completely baffled. And then there's the bloating, the acid reflux, and the food that feels like it's sitting in a brick in your stomach. That meal seems totally random and how it makes you feel, but none of it is actually random because it's your nervous system operating out of a different state. And so this is the one that gets people because most of us have been taught to think about food sensitivities as being about the food. You feel like maybe it was gluten, maybe it's dairy, maybe it's eggs or whatever. And so therefore you're trying to figure out what food maybe cause you bloating. But food sensitivities can be very contextual. They're not always about food. They can be about your nervous system state that you ate in, they can be about leaky gut, they can be about bile flow. There can be so many variables that affect how well you digest on every give given day. And specifically, you know, your stress levels, how well you slept, whether you ate in a rush or sitting at a desk in a meeting, whether you were already anxious or whether you were calm when you sat down to eat. So whether you're in a high pressure season at work or in the middle of an argument with someone or just coming off a week of not great sleep, all of these things will affect your nervous system state. And your nervous system state directly impacts how much stomach acid you produce, how many enzymes you release when you eat, and how well your gut is actually breaking down the food that you eat. So the same food in a stressed nervous system state in that fight or flight, in a depleted body, in the middle of a hard week, that food might wreck you. But that same food on a slow Sunday morning when you're rested, relaxed, and have time to eat, totally fine. This is why gut systems tend to symptoms tend to flare during stressful seasons, not because you suddenly started eating worse, but because your nervous system is under more of a load. And digestion is the first thing to go because digestion is optional, not important for safety. So here's where this gets really important for those of you who are in the thick of a gut healing journey right now and maybe not getting the results that you expected. A lot of women, understandably, because this is what a lot of practitioners recommend, jump straight into the heavy stuff. We do antimicrobial protocols, aggressive elimination diets, long supplement stacks. And if you've ever worked with a naturopath, then you've probably done one or many of those things. And sometimes that works. But sometimes, while those really necessary things, because there are real pathogens, real gut dysbiosis, and real structural things that are happening in the gut that need to be addressed, it can't be the only thing that's being addressed. Because the problem is, is if your nervous system, while you're doing all of the heavy lifting, is still in fight or flight, when you start that protocol, digestion isn't going to work well just because you're doing that protocol, because your supplements aren't going to absorb absorb the way they should. The protocol is going to feel harsh and overwhelming because your gut literally cannot handle the load and it might make you feel worse. Not because those things are wrong, but because you didn't have the foundational things first. And that order matters. I cannot say that enough. The order matters. And that's why in my one-to-one program, we do not throw the most aggressive gut protocol at your body in the beginning. Actually, your first six weeks with us are spent on the foundational habits that make those protocols work. Because you have to build the conditions that allow the digestion to function first. And that's a huge part of that, is that nervous system support. And as I said, this is something I take really seriously when I'm working with clients. We do not start by doing the most. We start by building the foundation. We have to calm your system, the same system that controls digestion, so that when we do address the gut directly, the body will actually receive it. Because once digestion genuinely improves, everything else becomes easier, absorption improves, energy improves, hormones are better supported, and the downstream effect of a calm functional gut are incredibly enormous, but you have to start in the right place. So, what does this mean for you? What do you do with this information? Well, first, this is what I do with my one-one clients. First, we start paying attention to your context, not just the food, but instead of logging just what you ate, start noticing how you felt before and during the meal. Did you sit down? Were you rushed? Stressed? Did you eat in front of a screen while working? Were you already depleted from a bad week? All of that context really matters. Second, take your nervous system state seriously as a part of any protocol. This means prioritizing sleep, getting seven to nine hours, building in real rest, not like I'll relax when things slow down, but intentional, scheduled rest. Eat in a calm environment. Eating in a calm environment when you can literally can be as simple as like when you sit down to eat, give yourself 20 minutes of silence, no phone, no screens, no work, and actually just take a few deep breaths. Three big deep breaths before you even have a bite can shift your nervous system so quickly from fight or flight into rest and digest. It's actually activating that parasympic nervous symptom, nervous system, that rest and digest state where digestion will actually happen. And third, if you have been doing these things where you're like, okay, I am sleeping seven to nine hours, I am eating in a relaxed state, I am taking care of my nervous system, and you are still not getting results, then we have to consider that deeper work, right? Consider whether or not your nervous system is a part of the picture. Because for a lot of women, it is the missing piece. Now, in closing here, you cannot have a calm gut in a body that feels under constant threat. That's it. That's literally the whole message. And I wish that someone had said this to me plainly years ago, because gut healing doesn't just start in the gut, it starts with the system that controls it. So when you address both, the root causes to why you actually might be dealing with digestion issues, the dysbiosis, the pathogens, the leaky gut, whatever it may be, and the nervous system, the way that you're eating, the way that you feel, that's when things will actually start to shift. So if today's episode resonated with you, I want you to share it with someone who maybe is also struggling with good stuff and feels like they're kind of spinning their wheels trying to figure out why nothing is working. Because this might be the simple refrain that they actually need. And if you're ready to stop trying to figure this out alone, then I work with Woman One through my company, RubyBoot Roots Co., to get to the actual root of what's going on. And you can find me on Instagram at Kenzie with2Z Grace. And I'll get back to you with another episode soon.
