- 2:59So now to the episode.
- 3:02Okay.
- 3:03If you are constipated and you also have fatigue.
- 3:07Or iron issues, or you've had low ferritin, low B12, or any walkie energy related lab markers.
- 3:16This episode might connect some of the dots for you because most people are told, if your ferritin is low, take iron.
- 3:24If it stays low, take more iron, and you might get constipated.
- 3:29But here's what almost no one talks about.
- 3:31What if constipation is the real reason that you're ironed?
- 3:35Isn't working, not just because constipation is annoying because it is, but because constipation signals to me that your whole system is moving too slowly and there's something else going on.
- 3:49And iron is just one of those first things that can stall when that happens.
- 3:54So today I wanna walk you through five simple layers that explain why this happens.
- 4:01We're not gonna get super complicated and sciency.
- 4:05But just go into how the body works, and if this starts to click for you, I want you to hold that thought until the end.
- 4:11So let's start at the very top of digestion with your stomach.
- 4:15It's not the the first step, but one of the first steps, I want you to think of your stomach, like a blender.
- 4:21When you put food into a blender, you expect it to break things down.
- 4:25I had a smoothie for breakfast this morning.
- 4:27It was.
- 4:27All blended up, right?
- 4:29But if you drink a smoothie and it had tiny chunks of pieces of food, that would not be very appetizing, right?
- 4:36So we expect this blender to break things down into tiny, usable pieces.
- 4:41Now, imagine you throw carrots, spinach, ice protein powder into the blender, which that would not be a very good smoothie, by the way, but that's just what came to mind.
- 4:49But maybe you barely turn it on, or the blades are dull.
- 4:53It kind of chops things up a little bit.
- 4:55And mostly there's just big chunks floating around.
- 4:59That is what low stomach acid is like, and your stomach is supposed to be as strong and acidic as battery acid almost, and that acid doesn't just.
- 5:09Sit there, it breaks food down into small pieces so your body can actually use it.
- 5:14Iron especially needs a strong acid bath is what we'll call it, and it has to be changed into a form that your body can absorb.
- 5:23So if stomach acid is low, iron doesn't get prepared properly.
- 5:29It's like trying to absorb a whole carrot instead of carrot juice.
- 5:32It just sits there half processed.
- 5:34And that is one of the biggest things that a lot of our clients struggle with, whether they have.
- 5:39Low iron or not, but if they have GI issues, and then when iron is sitting there, maybe from.
- 5:45Your supplements or from food it can make you nauseous.
- 5:49It can make you feel heavy.
- 5:50It can make your stomach hurt.
- 5:52It's not that the iron is bad, it's just not broken down completely.
- 5:57And so here's another thing that people don't think about is that stomach acid is not just for breaking down food, it's also for protection.
- 6:06You can think of stomach acid like a security guard at the front door.
- 6:10When your acid is strong, it kills off unwanted bacteria and parasites before they get comfortable.
- 6:18And when acid is weak, those things can sneak through.
- 6:21And this is why low stomach acid is often connected to things like h pylori, which is the most common infection in the world, parasites, other gut imbalances.
- 6:32This is not random.
- 6:34This is the front door security system not working very well.
- 6:39And that creates another problem because once organisms move in, they create irritation and irritation slows digestion even more.
- 6:49And that just becomes a cycle.
- 6:51Uh, there's a connection people rarely hear about, which is B12, B12, and iron often gets separated into different conversations, but in the body they can be deeply connected.
- 7:02B12 needs healthy stomach acid to be released from food when you eat animal or meat.
- 7:08Products, B12 is tightly attached to those proteins.
- 7:12And strong stomach acid is what breaks that bond.
- 7:15So B12 can be absorbed later in the small intestine.
- 7:18So if stomach acid is low, B12 doesn't get fully released and it just passes through.
- 7:24And you know what low B12 feels like?
- 7:26Fatigue, brain fog, low energy, sometimes tingling, mood changes.
- 7:31That sounds familiar, right?
- 7:33That's where it can get confusing because low ferritin or iron issues can also cause all of those symptoms.
- 7:40So I.
- 7:41If you feel exhausted or when one of our clients feels exhausted, we can't just assume it's just iron.
- 7:47It could be the whole digestive process.
- 7:49If stomach acid is low, you could have both low B12 and poor iron absorption happening at the same time, and that can look like that feeling of, I feel tired all the time.
- 8:00I can't think clearly, my workouts feel harder.
- 8:03I don't feel like myself.
- 8:05So let's just bring this back to iron.
- 8:07Low stomach acid doesn't just affect B12.
- 8:10Like I said, the interesting part is when I see low ferritin and low B12 together, you have to stop thinking about a simple deficiency and start thinking about the whole of absorption process.
- 8:24This is where lab work can be very helpful.
- 8:27Iron and B12 are absorbed in different parts of the small intestine.
- 8:32Iron is primarily in the upper portion.
- 8:35B12 is further down, but both require strong stomach acid and a healthy intestinal lining to be absorbed properly.
- 8:43So when they're low, it often points towards a bigger upstream issue, such as malabsorption or chronic inflammation, maybe celiac disease, h pylori, gastritis.
- 8:55PPI use or some form of small intestinal damage.
- 8:59So it's not just about iron intake, it's about how the iron and B12, et cetera, are being digested and absorbed.
- 9:08So to make it even more confusing, iron and B12.
- 9:12Deficiencies can cause anemia, but they produce different patterns.
- 9:16So iron deficiency typically leads to smaller red blood cells while B12 deficiency leads to larger ones.
- 9:23And so when those are low.
- 9:26Labs can look mixed or unclear, which is one of the reasons that these patterns sometimes are missed in practice because it affects everything that comes after it.
- 9:36If the stomach doesn't break food down well, the small intestine has to work harder.
- 9:41Food lingers longer.
- 9:43Digestion feels heavy, you maybe feel full more quickly.
- 9:47You may burp more.
- 9:48You may feel like food just sits there.
- 9:50And when food is lingering, movement slows.
- 9:54And that's where really the second piece comes in, which is motility.
- 9:59When movement slows, constipation becomes more likely.
- 10:03And when constipation sets in, iron handling becomes even more difficult.
- 10:08So iron struggles at the very beginning, not just because it's missing be, but because it never got broken down properly.
- 10:15You can think of it like an assembly line.
- 10:18Unassembled parts are going down this assembly line.
- 10:21The rest of the system is doing a good job, but it's working with incorrect parts.
- 10:27And iron is just one of those first nutrients to stall in that environment because.
- 10:33Of the need for that strong stomach acid and movement and coordination of the gut.
- 10:39So when somebody tells me that they're constipated and maybe they have iron issues, we don't really wanna just ask how much iron they're taking.
- 10:49We wanna first look at how strong is the blender, because if the blender a K, a stomach acid is doing its job.
- 10:57Adding in more ingredients or if the blender, sorry.
- 11:01If the blender is not doing its job, adding in more ingredients is not gonna fix that smoothie, right?
- 11:06It's still gonna be chunky.
- 11:08Sorry for the weird analogy.
- 11:10So let's talk about that second piece, which is slow motility and the movement of the gut muscles, the movement through the GI tract.
- 11:17I want you to picture like your kitchen trash can, right?
- 11:21So you went and dumped that smoothie out in the trash can.
- 11:24And if you take the trash out every single day, it never is a big deal.
- 11:29There's no smell, no overflow, no problem.
- 11:32But imagine if you stop taking out the trash day one.
- 11:35Not that bad.
- 11:37Day two, maybe it starts to smell.
- 11:38And day three, it's overflowing.
- 11:40So you're pushing it down, right?
- 11:42We all do this, like to avoid taking it out to make room, and that is what slow motility of the gut is.
- 11:48Like things move through at a healthy pace and waste leaves the body.
- 11:53It's quiet, it's normal.
- 11:55You don't think about it.
- 11:56But when movement slows down, waste will sit there.
- 11:59And when waste sits, bacteria will ferment.
- 12:02That can create gas.
- 12:04Gas creates bloating.
- 12:05Bloating creates pressure, and pressure slows things down even more.
- 12:09And so it becomes that loop.
- 12:12So one thing that I wanna connect for you here related to iron is your body wants to recycle iron.
- 12:19It doesn't wanna constantly pull.
- 12:21It in for more food or supplements.
- 12:24Your body is efficient.
- 12:25It reuses what it already has, but that recycling requires turnover.
- 12:30Like your laundry, right?
- 12:32If the washing machine is full of dirty clothes, but you never take'em out.
- 12:37You can't wash anything new.
- 12:39Even if you keep adding a detergent, it's not gonna get clean.
- 12:43So if nothing is moving out of your system, that recycling process is going to slow down.
- 12:49And now iron is harder to reuse, harder to store, which is the goal of ferritin, right?
- 12:55Ferritin is the stored form of iron and.
- 12:59It's more likely to sit in the gut and cause side effects.
- 13:02So this is why constipation is not just uncomfortable.
- 13:06It actually changes the way that things behave in the body.
- 13:09So when movement slows, iron is not just struggling to get in, it struggles to be used, and that's a completely different problem than, oh, you just need to take iron.
- 13:22Right?
- 13:23So let's actually zoom out a little bit more and talk about the third layer here.
- 13:28And this is a layer that you've heard me talk about on so many podcasts, and that is minerals.
- 13:35Your body runs on minerals, not in a trendy way, not in a, like you need a mega dose, all these random things way, but in a foundational electricity, muscle moving energy way, you.
- 13:47Have probably heard me talk about minerals as a symphony in your body.
- 13:52Minerals don't work alone.
- 13:54They work together.
- 13:55So one mineral that I wanna point out here is potassium.
- 13:59Potassium helps with muscle signaling.
- 14:02It's like the electrical current.
- 14:04In your body that tells muscles when to contract, we often associate potassium and bananas, right with muscle cramps.
- 14:12That's exactly what's happening.
- 14:14Magnesium helps to relax muscles, so movement can actually happen.
- 14:18Sodium helps to maintain fluid balance and supports nerve signaling, and all of them together help your digestive system to move and fire and coordinate.
- 14:29So how does this, why does this matter?
- 14:33Because your colon is a muscle.
- 14:35So if minerals are off, or especially if potassium is low, those signals are gonna be weak.
- 14:40If magnesium is low, your muscles will tighten.
- 14:43If sodium is low, that nerve communication gets sluggish, and if those signals are off, the colon is not going to contract properly.
- 14:50So that movement slows down, constipation sets in, and it doesn't really stop there because minerals.
- 14:58Also help your body to make stomach acid.
- 15:00So going up to that first layer that I talked about, they also help produce digestive enzymes, hormones, bile flow, they regulate your nervous system.
- 15:09So we have this chain reaction, low minerals, low stomach acid, poor breakdown of iron, slow motility, constipation, poor recycling, poor iron storage.
- 15:20And that's where people get stuck is because we're just focused on.
- 15:23Iron, but iron is not the conductor of this mineral orchestra.
- 15:28It's just one instrument, and if that orchestra is out of tune, adding a louder violin does not fix the music.
- 15:36Right.
- 15:38And this is why adding more iron doesn't fix low ferritin.
- 15:43In fact, often mineral depletion overall makes iron harder to tolerate, which is why maybe your constipation gets worse or you get cramping side effects increase because the foundation isn't there.
- 15:57So something important is mineral status is not.
- 16:00Always obvious on standard blood work, your blood is very tightly regulated.
- 16:06It will keep things looking normal for survival, but that doesn't always reflect deeper patterns.
- 16:13So one of the tools that we use clinically to assess mineral patterns is HTMA testing.
- 16:19Now, this would not diagnose anemia or low iron or low ferritin.
- 16:24But it does, and not just what's circulating in the blood at one moment.
- 16:28So I'm gonna go deep into that on my webinar on Sunday, but what I want you to know is that if iron hasn't worked for you.
- 16:37That mineral layer deserves attention because ferritin improves when your whole system improves and when your whole symphony improves, and minerals are a big piece of that.
- 16:49Now let's talk about layer number four, which is bile and liver load.
- 16:54So your liver makes bile.
- 16:55Bile has two big jobs.
- 16:57The first job is that it helps break down fats so that you can absorb nutrients, things like vitamin A, which is really important.
- 17:05Four iron recycling vitamin D as well.
- 17:09How many of you have low vitamin D?
- 17:12And then second, it helps to move things through your digestive track.
- 17:17Bile is like the dish soap, the washing machine detergent.
- 17:21It's when you wash a greasy pan with just water.
- 17:26The grease does not come off right.
- 17:27The grease just smears around.
- 17:29When you add soap, everything slides off and comes clean, and that's exactly what bile does in your body.
- 17:36It keeps things clean, it keeps stool from getting hard.
- 17:40It ke keeps things slippery.
- 17:42It helps waste to move out.
- 17:45And so here's the interesting thing that I wanna connect for you, is if bile flow is slow and your stool becomes drier, that movement is gonna slow as well.
- 17:56So that can be connected with slow motility and constipation.
- 18:00And remember constipation effects, iron handling.
- 18:05So let's talk just about the gallbladder for a second.
- 18:09Your gallbladder.
- 18:10Stores and, and bile releases.
- 18:13A, a very strong surge of bile after you eat, if you don't have a gallbladder, bile still gets made, but it just drips out slowly instead of being released in a strong pulse.
- 18:28So this means that bile flow matters.
- 18:30Whether you have a gallbladder or not, but it matters even more if you don't.
- 18:34And without that strong release, fat digestion can be weaker.
- 18:38This is where people get like intolerance to fatty meals or low vitamin D or burping bloating.
- 18:45Sticky stool, et cetera.
- 18:47So without that strong release, fat digestion, worsens and stool can be more inconsistent.
- 18:53And over time, that gut motility can be slower.
- 18:56And then if you layer in something like SIBO or small intestinal bacterial overgrowth.
- 19:02Bile isn't just for digesting fats, it's also keeping your bacteria in check.
- 19:07Remember, it's the dishwashing detergent.
- 19:10It has natural antimicrobial properties, so it's going to prevent bacteria from overgrowing in the small intestine.
- 19:18So if your bile flow is sluggish.
- 19:20Bacteria will have an easier time sticking around.
- 19:24And chronic SIBO is often tied to poor bile flow and slow motility.
- 19:29So here's the chain reaction that we're looking at.
- 19:32Sluggish bile flow, slow movement of the gut, bacterial overgrowth in the gut, inflammation, and then more sluggish bile, and it becomes a loop.
- 19:43So you can see where all these loops in the body really make an impact.
- 19:47Inflammation.
- 19:49Is one of the biggest signals that tells the body, do not prioritize iron storage, because when inflammation is present, the body is going to shift into defense mode and it becomes protective With iron, it hides it, it locks it down.
- 20:05If we zoom back to the liver, the liver is like the warehouse manager.
- 20:10It's gonna balance hormones, blood sugar, detox.
- 20:14Stress signals, inflammation, bile production, iron storage.
- 20:18And so if that warehouse is organized and things are moving out regularly, it can accept new inventory.
- 20:25But if that warehouse is backed up, if elimination is slow, inflammation is high.
- 20:31It's not going to storm or iron, and ferritin is your iron storage.
- 20:36So storage only happens when the system is organized and supported.
- 20:40And bile flow is not clearly just about digestion.
- 20:44It balances bacteria, it supports inflammation, or it helps reduce inflammation.
- 20:52And it helps as part of that iron storage process.
- 20:57So then related to constipation, you can think of that digestive tract, like a river, like I was saying.
- 21:04Bile helps keep things moving, keeps things slippery.
- 21:07When that river is flowing, everything is moving downstream.
- 21:11The water is clear, debris is not building up, and when that river slows, it becomes muddy.
- 21:17Sticky leaves start piling up.
- 21:19It doesn't settle proper properly, it gets caught in the mud, and that is what happens with iron.
- 21:26In a sluggish system, ferritin will rise when the river is flowing, not when things are stagnant and stuck and building up.
- 21:38Now let's zoom out one more layer to the nervous system layer number five, because you can do everything right with food and supplements and still feel stuck.
- 21:49And this is usually where stress enters the picture, not just emotional stress.
- 21:55Not just work stress, not just mom life stress.
- 22:00I'm talking about internal stress and external stress.
- 22:03External stress is what most of us think about first, right?
- 22:06Deadlines, kids waking up at night arguments, finances over training, et cetera.
- 22:12But internal stress matters just as much.
- 22:15So this is chronic inflammation, gut infections, blood sugar swings, mineral depletion, hormone shifts, postpartum, low thyroid function.
- 22:26Your body doesn't separate those things.
- 22:28Stress is stress.
- 22:29And when your brain senses.
- 22:31Whether it's from your inbox or from your insides your nervous system shifts into survival mode.
- 22:38And survival mode is not where you digest the best.
- 22:42So when the body thinks it needs to flight or flee, it's not going to prioritize that storage of iron.
- 22:52Stomach acid decreases bile flow decreases, motility slows, nutrient absorption drops.
- 22:59Everything that supports ferritin like we've just talked about, starts to quiet down because your body is trying to conserve energy.
- 23:07So the key here is that.
- 23:08Storage is not a survival priority.
- 23:12Ferritin is iron storage.
- 23:14And so storage happens when the body feels safe and resourced, not when it feels threatened.
- 23:22We can layer in the thyroid here.
- 23:23The thyroid is your metabolic speed dial, right?
- 23:27When the thyroid function slows, everything slows down as well.
- 23:32Digestion, motility, et cetera.
- 23:34We need iron for healthy thyroid function.
- 23:38If iron is low, thyroid function can struggle, and if thyroid function struggles, motility slows as well.
- 23:45So you can really see here, you're probably like, I wish I had a visual or a chart of this, which if you did, if you do, I will show you some on Sunday.
- 23:55But.
- 23:56All of this is connected, right?
- 23:58Stress, the nervous system, thyroid, how you're breaking down food.
- 24:03They all impact each other.
- 24:05So this is why someone can say, I'm constipated, exhausted, I'm taking iron.
- 24:11Nothing's working.
- 24:12But your system could be stuck in protection mode.
- 24:15And protection mode does not store.
- 24:18It's going to conserve.
- 24:19And until that stress load, both internal and external is addressed.
- 24:25Iron is.
- 24:25Trying to push against a locked door it cannot store it.
- 24:29So if you're constipated, your ferritin won't improve.
- 24:34This is why it's not just a fiber issue, and it's also not just an iron issue either.
- 24:39Much like maybe you've heard, constipation is a visible sign that your whole system is under functioning and that we need to address things like stomach acid, slow movement, mineral depletion, sluggish bile, nervous system stress.
- 24:56Iron will stall in that environment.
- 24:59And ferritin will improve when that system improves, not when you force it.
- 25:05I have a client example.
- 25:06Many client examples, but one in particular, she came to us with a ferritin of 14.
- 25:12She had been taking iron for a year and it was still 14.
- 25:16Every time she's.
- 25:18Adopt it.
- 25:19Her ferritin would drop again, and every time she took it, her constipation would get worse.
- 25:24So it was kind of a catch 22.
- 25:26She tried more fiber, more water, magnesium, you know, all the things, everything.
- 25:32And she was still only having one bowel movement every three to four days.
- 25:37She was bloated after meals, felt heavy after meals dragging in the afternoon.
- 25:41And when we zoomed out.
- 25:44What we could see here was her digestion was weak, her stomach acid was low, her minerals were depleted.
- 25:50Her stress load was really high internal and external.
- 25:54She had a lot of gut infections going on.
- 25:57She had a lot of work stress.
- 25:59The inflammation levels on her GI map tests were really high.
- 26:04So pulling her off the iron and restoring function to stomach acid, minerals, movement, bile flow, et cetera.
- 26:12All of a sudden she starts having bowel movements every day.
- 26:15Bloating decreases her energy started.
- 26:18Improving first minerals will do that.
- 26:21You can start to see improvement in energy so quick before you're gonna see ferritin jump on lab work.
- 26:28And then without increasing her iron dose, her ferritin slowly started rising, not because she was taking iron.
- 26:35But because the system finally had that capacity to store it.
- 26:39So that is the shift when the system works, iron will work.
