Weight gain with SIBO: How your gut could be blocking weight loss

You're eating clean, counting calories, and maybe even skipping the wine, yet the scale refuses to budge despite pushing through workouts multiple times a week. Or worse, it keeps creeping up. Sound familiar?

If you've been doing all the right things and still experiencing unexplained weight gain, then it's time to stop blaming your willpower and start looking deeper.

As a functional nutritionist specializing in gut health, I've worked with numerous women who have been frustrated by their chronic gut issues, which feel like an invisible weight holding them back.

But many don't realize that their gut might be the real culprit.

Specifically, an often-overlooked and commonly misdiagnosed condition called SIBO (Small Intestinal Bacterial Overgrowth) may be making it nearly impossible for you to lose weight and even causing you to gain weight.

What is even more confusing is that most people associate gut issues like SIBO with bloating, gas, and weight loss, and not necessarily weight gain. So when the pounds start piling on, many women are left feeling frustrated, ashamed, or worse, dismissed by doctors.

But here's something I want you to understand:

Weight gain with SIBO is very real, particularly in those with methane overgrowth (known as IMO).

It's not about overeating; it's about inflammation, hormone resistance, microbial imbalances, and a metabolism that's stuck in survival mode.

Understanding SIBO and IMO

If you’ve ever felt bloated after just a few bites of food, battled relentless constipation or diarrhea, or noticed you’re reacting to foods you used to tolerate just fine… there’s a good chance your gut is out of balance.

One of the most common and underdiagnosed culprits?
SIBO, or Small Intestinal Bacterial Overgrowth.

SIBO occurs when bacteria that normally reside in the large intestine overgrow in the small intestine, where they are not typically found. The small intestine is supposed to be relatively sterile, as this is where nutrient absorption occurs. But when excess bacteria move in, they begin fermenting the carbohydrates you eat prematurely in the digestive process.

That fermentation leads to:

  • Bloating (often within 30–90 minutes of eating), the feeling like you‘ve swallowed a balloon
  • Gas
  • Constipation or diarrhea (or alternating bowel movements)
  • Nausea, brain fog, and fatigue
  • Food intolerances (especially to FODMAPs)
  • Skin problems, joint and muscle pain
  • Nutrient deficiencies (especially B12, iron, fat-soluble vitamins) (1)

However, other microbes could overgrow, which is even more closely linked to weight gain, known as IMO, or Intestinal Methanogen Overgrowth.

What’s the difference between SIBO and IMO?

SIBO refers to bacteria in the small intestine. IMO refers to methanogenic archaea (ancient microbes), specifically organisms like Methanobrevibacter smithii, which produce methane gas.

These archaea aren’t technically bacteria, but they still cause major problems. Research also indicates that methanogens slow down intestinal transit time (leading to constipation, sluggishness, bloating, and weight gain) and are strongly associated with obesity and metabolic dysfunction. (2)

In simpler terms, if you have IMO, you’re more likely to be bloated, constipated, and gain weight even if you’re eating clean and exercising.

So, weight gain is common with methane-producing organisms. I have often observed this phenomenon with my clients.

And if you’ve been dismissed by doctors who only see SIBO or IMO as a “skinny person’s problem,” you’ve likely been misinformed.

This isn’t about calories in vs. calories out. It’s about a disrupted gut ecosystem that’s driving inflammation, hormone resistance, and a metabolism that’s no longer working for you.

How IMO can trigger weight gain

If you've ever wondered why your body seems to hold on to weight no matter how "healthy" you eat, it's time to look beyond calories and carbs and dive into what's happening deep inside your gut.

Let's break down the mechanisms.

  1. Methane gas = slower gut motility = more calories extracted

In a healthy digestive system, food moves through the small intestine in a rhythm known as the Migrating Motor Complex (MMC), much like a cleaning wave that occurs between meals. (3) But with SIBO or IMO, this wave slows down or stalls altogether. (4)

Methane-producing archaea (like Methanobrevibacter smithii) don't just sit there. They actively slow your gut motility even further, leading to constipation and a longer time for food to ferment and break down.

A study published in Neurogastroenterology & Motility confirmed that methane gas slows gut transit time and is directly associated with constipation-predominant IBS (IBS-C). (5)

But what does that have to do with weight?

The longer the food sits in your small intestine:

  • The more calories your body absorbs
  • The more glucose is released into your bloodstream
  • The more fat gets stored, especially around your midsection

So even if your input (diet) hasn't changed, your output (calorie absorption and fat storage) has. (6)

  1. Low-grade inflammation and leaky gut = metabolic chaos

SIBO and IMO aren't just mechanical problems. They create biochemical mayhem, too.

As these microbes ferment food where they shouldn't, they produce not just gas, but also lipopolysaccharides (LPS) and other endotoxins. These toxic byproducts can damage your gut lining, leading to what's often called "leaky gut." (7)

Once your gut barrier is compromised:

  • Inflammatory molecules enter the bloodstream
  • Your immune system goes into overdrive
  • Insulin resistance and fat storage increase

One study found that mice injected with LPS experienced weight gain and insulin resistance, even without changes in their diet. (8)

That's right: bacterial toxins alone can cause weight gain and metabolic dysfunction.

When inflammation is chronic, your body becomes more efficient at storing fat, especially in the abdomen and visceral organs. Add in sluggish digestion and poor detoxification, and you've got a perfect storm for stubborn weight gain.

  1. Hormones get hijacked

SIBO/IMO doesn't just stay in the gut; it disrupts your hormonal balance.

Inflammation and altered gut bacteria can interfere with:

  • Thyroid hormones (slowed metabolism)
  • Cortisol (stress hormone that drives belly fat)
  • Estrogen (can become dominant or poorly detoxed)
  • Leptin (your satiety hormone)
  • Insulin (your fat-storage hormone) (9)

The gut communicates directly with your brain and your fat cells. When it's inflamed, everything from hunger signals to fat storage cues gets scrambled.

And for women between 35 and 60, who may already be navigating perimenopause, menopause, or thyroid dysfunction, this can be the tipping point that leads to rapid and unexplained weight gain.

Weight gain with SIBO: How your gut could be blocking weight loss

When hormones go haywire

If you've ever felt like your body is working against you, craving sugar when you're not even hungry, storing fat despite eating clean, or feeling ravenous right after a full meal, you're not imagining things.

Two key hormones are often at the center of the storm: insulin and leptin.

When your gut is inflamed or overrun by microbes that don't belong, these hormones become dysregulated, sending your metabolism and your weight into chaos.

Insulin resistance

Insulin is a hormone produced by your pancreas that helps move glucose (sugar) from your bloodstream into your cells, where it's used for energy. It's essential to life, but too much of it, too often, is a problem. (10)

With chronic inflammation, such as that caused by SIBO or IBS, your cells become less responsive to insulin. So your body pumps out even more to try to compensate.

Over time, this leads to insulin resistance, where the signal is ignored, and excess glucose is stored as fat, particularly around the belly, liver, and internal organs. (11)

This is one of the primary pathways contributing to weight gain with SIBO, particularly in methane overgrowth, where inflammation and microbial imbalance are most severe.

A study found that gut dysbiosis (microbial imbalance) plays a direct role in insulin resistance, even in the absence of obesity. The study also revealed that certain bacteria were linked to increased fat deposition and blood sugar spikes, even in the absence of increased food intake. (12)

Leptin resistance

Leptin is another hormone, your satiety hormone. It's supposed to tell your brain, "Hey, we've had enough, time to stop eating."

But when your gut is inflamed, and your fat cells are in storage mode, your brain stops hearing leptin's message. This is known as leptin resistance, and it's a major driver of cravings, fatigue, and metabolic dysfunction. (13)

It becomes a vicious cycle:

  • Inflammation raises leptin
  • Chronically high leptin leads to leptin resistance
  • You feel hungry even when you've eaten
  • You store more fat, especially visceral fat
  • And that increases inflammation… again

This is why people with weight gain with SIBO or IMO often report intense cravings, energy crashes, and feeling "never satisfied" after meals.

How the gut microbiome influences insulin and leptin

The microbiome not only digests food but also plays a crucial role in how your body produces and responds to insulin and leptin.

Studies have shown:

  • Methanogens (Methanobrevibacter smithii) are associated with higher BMI and slower metabolism (14).
  • Disrupted microbiomes increase lipopolysaccharide (LPS) levels, which contribute to both insulin and leptin resistance (8).
  • Gut-derived short-chain fatty acids (SCFAs) can modulate both insulin sensitivity and fat storage, but overgrowths like SIBO disrupt this production. (15)

In essence:

A gut that’s out of balance throws off your hormonal thermostat, leaving you stuck in fat-storage mode, even if you’re eating “perfectly.”

You can't "out-willpower" hormonal resistance

If you've been trying to lose weight by cutting calories, skipping meals, or doing extra cardio, but nothing is working, it's time to stop blaming yourself.

The problem isn't your discipline. It's your biochemistry.

Especially for women already juggling fluctuating estrogen, thyroid shifts, and stress hormones, gut-driven hormone resistance can tip the scales in the wrong direction fast.

And guess what? That's often exactly when SIBO or IMO sneak in after a round of antibiotics, a stressful life event, or a shift in hormones that slows gut motility.

What else could be causing the weight gain?

When investigating the possible causes, it’s worth looking beyond the microbes themselves.

Because while SIBO and IMO can absolutely be primary drivers of weight gain, they don’t operate in isolation.

In fact, for many people, there are multiple overlapping root causes feeding the inflammation and dysbiosis.

Let’s take a look at what else could be contributing to weight gain with SIBO:

1. Mold toxicity

This one often flies under the radar, but mold exposure is increasingly being recognized as a major contributor to SIBO, leptin resistance, and weight gain.

Mycotoxins (like ochratoxin A, aflatoxin, and gliotoxin), produced by mold species such as Aspergillus, Penicillium, and Stachybotrys, are potent disruptors of the gut-brain-hormone axis. (16)

They can:

  • Damage the gut lining, worsening leaky gut
  • Suppress immune function, making it easier for bacteria to overgrow
  • Disrupt bile flow and detoxification, which slows motility and impairs microbial clearance
  • Inflame the hypothalamus, contributing to leptin and insulin resistance

A 2020 study found that chronic exposure to mycotoxins impairs intestinal barrier integrity and alters immune function (17), which could set the stage for SIBO and metabolic dysfunction.

And because mold toxicity often goes undetected, many people end up in a SIBO treatment loop, meaning they feel better temporarily, only to relapse again and again.

So if you’re someone who:

  • Has lived or worked in a water-damaged building
  • Is extremely sensitive to supplements or smells (chemicals)
  • Feels puffy, foggy, and inflamed all the time
  • Has relapsing or treatment-resistant SIBO

Mold should absolutely be on your radar.

Tip: Urine mycotoxin testing (via RealTime, Vibrant, or Mosaic Diagnostics) can help uncover hidden mold exposure, while GI-MAP can show whether your gut immune system (sIgA) is suppressed. Of course, it is a top priority to identify the source of mold exposure and invest in remediation.

2. Hormonal imbalances

When your gut is inflamed, your hormones can’t function properly. Period.

I have already mentioned insulin and leptin, but other hormones may also be imbalanced:

  • Estrogen dominance is common when detox pathways are sluggish or the microbiome is imbalanced (especially if beta-glucuronidase is elevated -> this can often be detected on a GI MAP test).
  • Cortisol dysregulation from chronic stress or trauma can lead to belly fat accumulation and blood sugar imbalances.
  • Thyroid hormones are often suppressed by inflammation and nutrient deficiencies (like iodine, selenium, or zinc), slowing metabolism further.

And the gut is directly involved in metabolizing these hormones.

If detox pathways are blocked either by SIBO, mold, or poor liver function, it creates a hormonal traffic jam that feeds back into the cycle of fatigue, cravings, and fat storage.

3. Medications that alter the microbiome and metabolism

Sometimes the tools we use to manage symptoms can actually worsen the root cause.

Wait, what?

Yes, unfortunately, certain medications are commonly associated with weight gain and microbial imbalance:

  • Proton pump inhibitors (PPIs) – suppress stomach acid production, widely prescribed for GERD patients to alleviate reflux symptoms, indirectly leading to weight gain (18) and promoting bacterial overgrowth (19)
  • Antibiotics – wipe out beneficial bacteria and open the door to dysbiosis (20)
  • SSRIs and other psych meds – can contribute to weight gain and gut-brain axis dysfunction (21)
  • Steroids – may induce cortisol imbalances (22)

So if you’re on them and struggling with weight gain with SIBO, they may be part of the bigger picture.

4. Sleep deprivation and circadian disruption

Your gut has a clock, and so does your metabolism.

Poor sleep or erratic sleep schedules (shift work, blue light exposure, etc.) can:

  • Disrupt insulin sensitivity (23)
  • Alter the composition of your gut microbiome (24)
  • Increase ghrelin (hunger hormone) and decrease leptin (satiety hormone) (25)
  • Suppress melatonin, impacting gut healing and motility (26)

Even just one night of poor sleep can increase cravings, slow digestion, and worsen blood sugar control, especially in people already dealing with gut inflammation.

5. Chronic stress and nervous system dysregulation

Last but definitely not least: stress.

Ongoing emotional or physical stress leads to (27):

  • Elevated cortisol → insulin resistance → fat storage
  • Suppressed stomach acid and digestive enzyme output
  • Slowed gut motility (perfect for SIBO to flourish)
  • HPA axis dysfunction → burnout, fatigue, and low resilience

Chronic stress also reduces vagal tone, which is the nerve signaling required to keep digestion moving, inflammation low, and the gut-brain connection healthy. (28)

That’s why nervous system support, such as breathwork, somatic practices, or vagus nerve stimulation, is a non-negotiable piece of long-term healing.

Holistic healing means seeing the whole picture

For many, weight gain with SIBO is a symptom of deeper dysregulation, not just in the gut, but across the immune system, hormones, liver, and even brain.

That’s why treating SIBO alone without addressing mold, hormones, stress, and sleep often leads to relapse and frustration.

But when you treat the whole system, your body responds. Healing becomes possible. And the weight that felt “stuck” can finally start to shift without crash dieting or burning yourself out.

Healing your gut to lose the weight

Let's face it: conventional weight loss advice, eat less, move more, doesn't work when your gut is inflamed, your hormones are out of sync, and your metabolism is stuck in storage mode.

If you've been struggling with weight gain with SIBO, you don't need another fad diet or punishing workout plan.

You need a strategy that starts from the inside out.

Here's exactly how I approach sustainable weight loss through a functional, gut-healing lens.

Test, don't guess

Guessing leads to burnout. Testing leads to results.

To understand the root causes behind your weight gain, bloat, fatigue, and mood changes, it's essential to map the terrain.

Functional tests to consider:

  • SIBO Breath test (lactulose or glucose) – to determine if you're dealing with hydrogen, methane, or hydrogen sulfide, as each type may require different approaches
  • Comprehensive stool test (e.g., GI-MAP stool test) – reveals gut pathogens, leaky gut markers (zonulin), immune function (sIgA), beta-glucuronidase, digestive function
  • Mycotoxin urine test – screens for mold exposure (a hidden driver of SIBO + leptin resistance)
  • DUTCH hormone panel – evaluates cortisol, estrogen, progesterone, androgens, and metabolic detox pathways
  • Fasting insulin, leptin, and glucose – to detect metabolic resistance early

These tests create a personalized map for healing, not a cookie-cutter protocol.

Treat the overgrowth

If you've confirmed SIBO and/or IMO, clearing the overgrowth is a must, but how you do it matters.

Approaches that work:

  • Herbal antimicrobials – like berberine, neem, allicin, and oregano oil (proven effective and gentler on the microbiome) (29)
  • Elemental diet – a short-term (usually 14-day), liquid formula diet that starves bacteria while nourishing you with an 80% success rate (30)
  • Rx antibiotics – Rifaximin for hydrogen; Rifaximin + Neomycin for methane (when clinically appropriate)
  • Motility support – prokinetics (ginger, Iberogast, low-dose erythromycin) are crucial post-treatment to prevent relapse

Without motility support, you'll likely see SIBO return, especially if methane was involved.

Adjust your diet

Temporary dietary changes can reduce symptoms and inflammation, but this isn't about long-term restriction.

Effective strategies:

  • Low-FODMAP or SIBO-specific diet – short-term, to reduce fermentable carbs feeding the overgrowth
  • Lean into anti-inflammatory, blood-sugar-stabilizing foods – think protein, leafy greens, healthy fats, cooked veggies, and herbs
  • Avoid sneaky fermentables – like sugar alcohols (xylitol, erythritol) and high-inulin prebiotics (chicory, raw garlic/onion)
  • Add gut-soothing foods – bone broth, ginger tea, aloe vera juice, steamed veggies

Most importantly: don't undereat. Chronic restriction worsens cortisol and slows metabolism, a disaster for weight gain with SIBO.

Support gut barrier repair

Your gut lining is the frontline of your immune system and metabolism. If it's damaged, your entire body feels the impact.

Supplements that help:

  • L-glutamine – fuels intestinal cells and promotes repair
  • Zinc carnosine – heals and protects the gut lining
  • Colostrum – boosts sIgA and mucosal immunity
  • N-acetylcysteine (NAC) – supports detoxification and mucus production
  • Quercetin + curcumin – reduce inflammation and histamine reactions

Think of these as "spackle" for your gut lining—rebuilding what the overgrowth tore down.

Balance hormones + stabilize blood sugar

Your gut and hormones are on a two-way street. Healing one supports the other.

What to focus on:

  • Stabilize blood sugar – prioritize protein and healthy fat at every meal; avoid long fasting windows if you're dealing with adrenal issues
  • Lower insulin naturally – through berberine, chromium, and moderate carb cycling
  • Improve leptin sensitivity – optimize sleep, lower inflammation, address mold or endotoxin exposure
  • Support liver detox – with bitters, dandelion, milk thistle, and cruciferous veggies

Weight gain with SIBO often involves leptin and insulin resistance, and until that's addressed, fat loss will feel impossible.

Work with your nervous system, not against it

Stress isn't just a mindset; it's a physiological state that affects motility, digestion, detox, and fat storage.

When you’re in fight-or-flight, your body:

  • Slows digestion and detox
  • Increases cortisol
  • Raises blood sugar
  • Stores fat for "emergency use"

Tools to regulate your nervous system:

  • Breathwork and vagus nerve stimulation (like humming, gargling, or cold exposure)
  • Somatic practices (like yoga, Qi Gong, or TRE)
  • Nature exposure and low-intensity movement (walking in sunlight > HIIT when healing)

You cannot heal in a state of chronic stress. Period.

What to avoid when healing from SIBO:

  • Extreme fasting or long-term keto (can slow motility)
  • Excess probiotics during active SIBO (can feed the wrong bacteria)
  • Over-supplementing without testing
  • "Killing protocols" without gut lining or liver support
  • Ignoring stress, sleep, or trauma in your healing journey

The bottom line

If you've made it this far, you're probably someone who's been dismissed, misdiagnosed, or misunderstood more times than you can count.

Perhaps you've been advised to simply eat less, exercise more, or try harder, as if your willpower is the issue.

But now you know better.

You know that weight gain with SIBO isn't about laziness or lack of discipline. It's a biological response to inflammation, gut imbalance, hormone disruption, and often years of being in survival mode.

And most importantly, you now understand:

  • That your gut impacts far more than digestion
  • That methane overgrowth and mold exposure are real drivers of weight gain
  • That sustainable weight loss starts with gut healing and hormone balance, not calorie restriction
  • That healing your body is not about punishing it, it's about listening to it

Because your symptoms aren't a nuisance.

They're messages, and they're asking you to go deeper.

Mold Toxicity and SIBO – the invisible threat to your gut health

Suppose you have been struggling with mysterious symptoms like unexplained chronic fatigue, brain fog, and digestive or sinus issues that don't seem to go away even after doing some gut-healing protocols. Maybe you have tried every single SIBO protocol without success. In this case, there might be a not-so-obvious reason for having those chronic symptoms, and the culprit might be toxic mold exposure, as was in my case.

Mold is not fun. It can (literally) eat you up and make your life miserable. I felt pretty well after healing my gut from SIBO, but I still couldn't shake off the deliberating fatigue and brain fog I had on most days. During that time, we also encountered water damage in our apartment – water dripped from the ceiling because a pipeline was broken behind the wall. At first, I didn't realize how serious this could be, but later a light bulb turned on in my mind, what if there is mold?

mold toxicity and gut issues

Mold Toxicity: The Invisible Intruder

What the heck is mold?

Mold (or mould) is a natural part of the environment, a type of fungi that can grow on many indoor and outdoor surfaces, requiring oxygen and moisture to start growing. Mold releases tiny spores in the air to spread. There are many different species of mold, and many of them are not even identified.

Unfortunately, mold is a widespread problem nowadays in buildings. We need to talk about it since we spend too much time indoors, and health risks are associated with mold that grows indoors that may have been exposed to water damage. But it can also happen if there is no proper ventilation installed in the building and the air humidity gets too high.

Foods like nuts, dried fruits, apples, coffee, and cereals, can also be contaminated with mold (more about them later) that we may ingest.

What about mycotoxins?

These toxins are present in mold fragments and spores released into the air. They can enter our body through inhalation, the skin, or even by ingesting mold-contaminated foods, creating havoc on the body.

Mycotoxins can have a negative impact on many bodily functions. Many people may have heard that it can lead to respiratory issues (asthma, sneezing, runny nose, breathing issues), but mold toxins may affect more than just that. It can impact the gastrointestinal tract, nervous system, immune function, and many other organs. Mold toxins can lead to the condition called: Chronic Inflammatory Response Syndrome (CIRS).

The most common mycotoxins are:

  • Trichothecenes
  • Fumonisins
  • Ochratoxins
  • Aflatoxins

What are the typical signs of mold toxicity?

  • Fatigue and weakness
  • Headaches, light sensitivity
  • Insomnia
  • Poor memory, difficult word-finding
  • Difficulty concentration, brain fog
  • Morning stiffness, joint pain
  • Unusual skin sensations, tingling, and numbness
  • Shortness of breath, sinus congestion, or a chronic cough
  • Appetite swings, body temperature regulation,
  • Increased urinary frequency or increased thirst
  • Red eyes, blurred vision, sweats, mood swings, sharp pains
  • Abdominal pain, diarrhea, bloating, food sensitivities
  • Tearing, disorientation, metallic taste in your mouth
  • Static shocks
  • Vertigo, feeling lightheaded

There is also a phenomenon that even though a family of 4 live in a water-damaged building, it can happen that only one member of the family will show the symptoms. Why? First of all, each of us is built differently, and some people can clear out toxins better than others, but there is another explanation. Around 25% of the population has the DLA-DR gene meaning that these people are more susceptible to mold toxins than those without that gene. These people have difficulty clearing mold toxins even after getting out of the exposure.

Why should you care about mold toxicity if you have SIBO or gut issues?

What is SIBO?

Small Intestinal Bacterial Overgrowth (SIBO) is a condition in which an excessive number of bacteria accumulate in the small intestine. SIBO can cause a wide range of gastrointestinal symptoms, such as bloating, gas, abdominal pain, constipation, and/or diarrhea. The overgrowth of bacteria can also interfere with nutrient absorption, leading to deficiencies and further health complications. Read about the SIBO types here.

 

 

Mold Toxicity and SIBO Connection

Mold toxins can disrupt the function of the Migrating Motor Complex (MMC) by interfering with the chemical signaling that would activate the MMC.

MMC is responsible for sweeping the remaining bacteria and food particles from your small intestine toward the colon between meals. A well-functioning MMC is crucial in preventing SIBO (Small Intestinal Bacterial Overgrowth).

They can also damage the intestinal wall (causing a Leaky gut and intolerances), hindering nutrient absorption.

Also, mold toxins can suppress the immune system and cause systematic inflammation by altering the gut microbiome (disrupting the balance between beneficial and pathogenic gut bacteria). The consequence is that Candida or other pathogens (bacterial, viral, parasitic infections) can start growing out of control.

To recover from SIBO, you also need a well-functioning immune system that may be depleted due to fighting mold and other bacterial toxins all the time.

How to know if you are affected by mold toxicity?

Test your home/workspaces  

If you live in the US, you can hire local inspectors to assess your home, workplace, and car. ERMI mold test completed by a trusted inspector is one of the best.

Where can mold hide?

Mold can hide in many places in your home, but it mostly loves warm, dark, and moist environments. But other areas like your workspace and car can also house mold.

  • Basements, attic area
  • Carpets, rugs
  • Behind furniture
  • Window sills
  • Air conditioning, Air ducts
  • Seals, coils, and drip pans on electronic devices like front-load washing machines, tumblers, refrigerators, dishwashers
  • Books, paper, documents
  • Beneath the wallpaper
  • Kitchen, and bathroom area, sills, sink, plumbing, etc.
  • Water filtration systems
  • Boilers and Water Heaters
  • Plants
mold hide in your home gut issues

Test your body

Testing is essential, but it's not perfect. You can use various testing methods to see what is going on.

  • Urine Mycotoxin Testing (from Great Plains Laboratory) - measures the levels of mold metabolites in a urine sample; it tests for 11 different mycotoxins
  • Organic Acid Test checks for 76 markers providing information about abnormalities in the person's chemical pathways. It can also detect if mold, bacterial or fungal overgrowth can be an issue
  • Visual Contrast Sensitivity Testing (VCS) - measures some neurological functions. It checks your ability to see details at low contrast levels
  • Blood test - measures antibodies for mycotoxins

If you also have gut-related symptoms, stool testing is advisable to see if other infections or pathogens are lurking in your gut.

First steps to deal with mold toxicity

Control your environment

The first step is to get out of the mold exposure. It is tough to heal your body if constantly exposed to mold.

You cannot heal in the same environment that made you sick.

You either need to invest in getting complete remediation, or you need to move to another place.

Moving can be one of the most complex decisions. We also decided to move to a new apartment after living in our previous flat for more than 8 years, and we loved living there, so this was not an easy decision. But health comes first, always!

You can also improve the indoor air quality by using an air purifier or dehumidifier to keep humidity low and filter the air for mold particles + using a ventilation fan in the bathroom.

Open your detoxification pathways

Incorporating lifestyle changes that support your body's detoxification is crucial for eliminating toxins like mold.

  1. Daily pooping – is super important to get rid of waste and toxins daily. (avoid constipation at all costs!)
  2. Hydration – Drinking 8-10 glasses of water (or herbal teas, broths, and veggie juices) can help improve bowel movements and detoxification.
  3. Sweating – Improving detox pathways, in this case, the skin to release toxins can be helpful. Exercise or a sauna are great ways.
  4. Soaking in Epsom salt baths – can help remove toxins and reduce inflammation. Add a few cups of Epsom salt to your bath or a few tablespoons of Epsom salt to a foot bath.
  5. Liposomal glutathione – is an antioxidant compound synthesized in the liver detoxification cycles, and it helps eliminate toxins from the body. Exposure to mycotoxins can deplete glutathione levels, leading to mitochondrial damage.

Use binders

Binders aid in absorbing metals, toxins, and compounds throughout any detox process, minimizing detox symptoms. Without binders, you can't complete any detox regimen!

Choosing a suitable binder is vital depending on the type of mold toxicity you have.

Zeolite is a powerful binder. Zeolite is a silica-based volcanic ash (sand-like mineral) that forms over time when ash and lava from volcanoes chemically react with seawater. Zeolite binds to radioactive poisons, mildew/mold, chemicals, heavy metal toxins like mercury, VOCs (volatile organic compounds—what carpets and furniture emit—and free radicals). All of the positively charged (+) toxins bind to the naturally negative (-) charge that zeolite bears.

But other potent binding agents such as Cholestyramine, activated charcoal, and bentonite clay can reduce the mycotoxin levels in the gut.

Be aware of taking binders 1 or 2 hours away from medications, supplements, and foods; some may cause constipation!

high mold foods, low mold diet

Get on a low-mold diet

Mold can grow on plant foods because of climate (hot, humid environment), improper food storage, transportation, etc. Since you can also be exposed to mold through food, avoiding or reducing mold-containing foods can be essential for a while.

The low-mold diet can mean eliminating or reducing:

  • sugar, alcohol, and processed foods,
  • cheese,
  • dried fruits (apricot, figs, dates, etc.),
  • store-bought fruit juices,
  • mushrooms,
  • sauces, spices,
  • grain-fed animal products, including cured and smoked meats,
  • most (gluten-containing) grains, especially wheat, barley, rye, corn, rice,
  • peanuts, and other nuts (pistachios, cashews, and Brazil nuts),
  • coffee (choose a mold-free coffee if you are a coffee lover like me!).

You can still enjoy the following:

  • grass-fed, pasture-raised animal products; organic eggs
  • wild-caught fish and seafood
  • fresh, organic vegetables (the more colorful they are, the better!);
  • low-sugar fruits: Berries, apples, pears, peaches, avocadoes
  • healthy oils and fats (extra virgin olive oil, coconut milk, coconut oil, ghee, avocado, organic grass-fed butter)
  • seeds: Sunflower, pumpkin, flax, chia, sesame seeds
  • legumes: lentils, beans
  • gluten-free grains: quinoa, buckwheat, millet, teff
  • quality herbs and spices
  • toxin-free coffee such as Bulletproof

It is also crucial to carefully inspect the foods you buy or store in the fridge and discard anything that you find to be infected to be mold. Check the surrounding foods, as mold can quickly spread.

The bottom line

Mold toxicity is an invisible threat that can severely impact gut health, contributing to the development of Small Intestinal Bacterial Overgrowth (SIBO). Understanding this connection is crucial in safeguarding your gut health and overall well-being. By taking appropriate measures to address mold toxicity, you can protect your gut and reduce your risk of SIBO, ensuring a healthier, happier you.
