People think of mold when they cough, sneeze or have their eyes itch while they are in the room. But what is not talked about often is how mold can slowly and systematically break down your gut health without alerting you to the connection for months if not years.

But if you’ve felt bloated, digestion all over the place, brain fog, fatigue and food sensitivities that spring up out of the blue, perhaps mold is the connecting thread. And the disappointing aspect? You might not be aware you’re being exposed.

Let’s take a quick second to explain just what’s going on in your gut – and why mold can be much more harmful to your overall well-being than you realize.

The Hidden Source Most People Never Consider

Not all molds are created equal; it is not always a black fuzzy patch on the ceiling of a bathroom. The Environmental Protection Agency reports that mold is generally invisible 50% of the time, under floorboards, in areas of any moisture or water damage, behind appliances and inside wall cavities.

Another possible route of exposure is via food. You might be ingesting mold or moldy products without being aware of it, as the mold can be present in grains, dairy products, nuts and certain processed foods.

It is because mold is slow, steady, and invisible that it can cause damage to your gut over time. This is no big event. It’s a gradual process that can undermine your body’s balance.

What Mold Does to Your Gut – Step by Step

1. It Throws Off Your Gut’s Inner Community

There are trillions of living things in your gut that help you feel healthy, whether they are helping you to digest your food, absorb the nutrients or maintain your body’s defenses and your mood. Once mold particles are introduced into your system, they start to upset this whole community.

The balance tips. Helpful and beneficial organisms as a whole are reduced. The negative and disruptive ones prevail. This change, which is referred to in wellness terms as dysbiosis, not only leads to an upset tummy, but also to intestinal inflammation. It impacts your energy levels, your mental clarity, as well as how your body reacts to regular stress, and foods.

2. It Weakens Your Gut Lining

Imagine there is a fine-mesh screen lining your gut. It’s supposed to allow it to pass on what is needed to the body, nutrients, water, vital compounds, and keep out what is not.

Those substances caused by mold are known to compromise that lining. If it leaks, the substances that should be contained go into the blood supply. Your resistance to them becomes intensified, and a cycle of constant irritation within your body develops, affecting almost every body system.

This is what is known as “leaky gut” and is one of the major ways mold is causing wide-spread damage, without anyone ever knowing.

3. It Blocks Nutrient Absorption

While some people eat well, exposure to mold can disrupt how well their gut absorbs what they put in. Some mold compounds interfere with your gut’s ability to absorb essential nutrients like sugars and carbs. The result? Even if you are eating well, you could have nutrient deficiencies, unexplained tiredness and weight shifts.

Over time, these can lead to an imbalance of bacteria in the small intestine, further worsening digestive turmoil.

4. It Fuels Ongoing Internal Irritation

Perhaps the most important and rarely discussed impact of mold exposure is the continuous irritation that occurs within the gut. Mold products produce an allergic reaction that enables your body to stay in a state of alert. This is connected to a higher sensitivity to foods or drinks that were previously consumed with no problems, continual stomach troubles, and a tummy that acts strange as to most everything.

The difficulty is the irritation the mold causes within the body is not always eliminated when the exposure ceases. It may have a disruptive effect that remains and continues to exacerbate symptoms even after you have left the source.

5. It Weakens Your Gut’s Defenses

Your gut contributes to a whole lot of your resilience. Mold can wreak havoc on the inner community and lining of your gut, and in doing so, also wreak havoc on your body’s ability to protect itself from other unwanted invaders, leaving you more susceptible to gut infections and exacerbating the damage.

Signs Your Gut May Be Struggling From Mold Exposure

Mold damage to the guts occurs over time and is often so subtle that one can easily overlook the symptoms. Note some of the patterns:

• Brain fog, concentration problems or fatigue
• Developing or aggravated allergy to food.
• Frequent or unexpected lack of energy, which does not go away with rest
• An unexplained loss or gain of weight or appetite
• Overall sensation that your body is not functioning as it previously did. 

None of these signs individually directly indicate mold, but all of these signs, taken together, and if they are not resolved by any of the other steps described herein, merit further investigation.

What You Can Do to Support Your Gut

The first step in dealing with gut disruption from mold is to determine the source of exposure. However, this is just the first step. The damage that occurs in the gut can last long after the exposure occurs, making it important to think about your environment, your food habits, your lifestyle habits, and what your gut needs to start healing after the exposure ends.

Eating foods that are whole and not processed and avoiding food products treated with mold-related substances is a good first step. The importance of the sugar issue and processed grains (fungi) is reduced. Re-establishing a healthy balance of the inner community in the gut takes time and consistency.

Most important of all, this isn’t something that just goes away when you are given a blanket recommendation. Your gut disruption due to mold is completely subject to you and your reactions and sensitivities to mold, as well as the patterns that may remain in your life that are continuing to cause issues.
