The adverse health effects of mold are some of the most pervasive, and least understood, health issues in today’s world. Unfortunately, it’s a health issue many doctors miss.

Like Lyme disease, mold is the “great masquerader.” It can cause a wide variety of symptoms to appear, mimicking other illnesses. Over the years I’ve learned that if someone is sensitive to mold and is quite ill there is nothing more important than treating the underlying mold problem.

That’s because if the mold-induced illness isn’t addressed first it can cause an enormous amount of inflammation, free radical stress, and toxicity in the body.

What Are the Symptoms of Mold Exposure?

Toxic mold symptoms can include:

  • Fatigue,
  • Weight gain,
  • Headaches,
  • Asthma,
  • Coughing or wheezing,
  • Chronic sinus infections,
  • Muscle and joint pain and weakness.
  • Symptoms of mold exposure can also include:
  • Visual disturbances,
  • Balance issues,
  • Trouble concentrating and “brain fog”,
  • Dizziness,
  • Irritable bowel syndrome (IBS),
  • Skin rashes,
  • Fever,
  • Swollen lymph nodes,
  • Mood swings,
  • Numbness and tingling,
  • Nosebleeds.

The most common health effects of mold I see in adults is mental and physical fatigue, headaches, morning sinus congestion, and muscle aches. For children, asthma and a cough are common, as is a suppressed immune system where they catch every cold and flu that goes around.

Toxic Mold Symptoms Can Vary With the Type of Mold

There are thousands of mold species, some helpful and some problematic. On the positive side, some mold species help to recycle organic matter which is very important for the ecosystem. Other mold species are utilized for food production—for instance making bread, cheese, sausage, and alcohol. Plus there are medications created from mold, such as penicillin, lovastatin, and cyclosporine.

But other mold species can cause the types of toxic mold symptoms I mentioned earlier. “Sick building syndrome,” for example, often results from mold spores circulating in the air ducts of a building. These tiny spores, invisible to the naked eye, can produce mycotoxins that make us sick. Mycotoxins can be absorbed through the intestines, lungs, and your skin. The most problematic mycotoxins include ochratoxin A, aflatoxin, and trichothecenes.

Mold Exposure Is Likely If...

  • Your home or office has water damage or water intrusion and nothing was done to remediate it within 24-48 hours. Mold can grow with very little moisture, so make sure small leaks are repaired and damp areas like bathrooms, showers, and windowsills are well ventilated and cleaned regularly.
  • You smell a musty odor. That odor is often caused by microbial volatile organic compounds (VOC’s) which are not thought to affect our health in a negative way. This musty odor, however, is a red flag that mold growth is present.

There are also many companies that will come to your home and test for the presence of mold spores. One of the most popular mold testing methods is to collect air samples indoors and outdoors and compare them. The indoor mold count should be less than outdoors. Unfortunately, air testing for mold is limited in its effectiveness and can lead to false negative results since it only provides a brief snapshot in time of which mold spores are present.

One of the better, more effective, tests for mold is the Environmental Relative Mold Index (ERMI) which is available at Mycometrics or EMLab P&K. It analyzes a sample of dust from the home using a DNA-based method for identifying specific mold species. This test also has its limitations, but overall is a good test to start with.

You can also place petri dishes in suspicious areas for a short amount of time and send in for an analysis called Immunolytics. This can be an inexpensive option to determine if mold is growing in your home. Yet, this test can lead to false negatives. So if you strongly suspect mold and the test comes back negative seek other testing methods above for a second opinion.

How To Test For Mold Inside Your Body

One reason mold is so harmful is the spores and mycotoxins create a domino effect, causing your body’s inflammatory response to go into overdrive. And some people are more vulnerable to these health effects than others.

About 24% of the population has a genetic susceptibility (HLA-DR) that prevents proper excretion of mycotoxins. In other words, once you’ve been exposed to mycotoxins they continue to recirculate in your body, resulting in an overactive immune response that disrupts many symptoms in the body.

If you suspect you have toxic mold symptoms or a mycotoxin illness traceable to an exposure to a water damaged building, seek help from an integrative physician who is knowledgeable about the health effects of mold.

He or she may run the following labs to test for mold:

  • TGFb-1 (Labcorp),
  • MMP-9,
  • C4a (National Jewish Health),
  • CD-57 (Labcorp),
  • HLA –DR 1-5 and DQ (Labcorp),
  • VEGF,
  • MSH,
  • Mold IgG allergen panel (Labcorp).

Most of these labs are non-specific, so other medical conditions need to be ruled out.

There is also a urine test available through RealTime Laboratories that tests for mycotoxins. It shows you how many mycotoxins (in parts per billion) are being excreted in the urine, which can provide valuable information about mold exposure. This test is available through some integrative medicine specialists. However, it is very expensive—costing close to $700 so you want to keep that in mind.

Finally, there is an online test called the Visual Contrast Sensitivity Test that is a great screening tool for biotoxin exposure. Biotoxins, including mycotoxins, can disrupt neurological function, and alter the ability of your eyes to contrast shades of light and dark. If you fail this test there’s a 92% chance that neurological function is affected by a biotoxin such as a mycotoxin produced from mold.

The Good News Is That the Health Effects of Mold Are Treatable

Once you determine mold is making you ill, there are many treatments to remedy the situation. First and foremost, the source of the mold must be eliminated. Consider hiring a professional remediation crew so you don’t risk exposing yourself to more mold spores and mycotoxins. Remediation can be an expensive process, so make sure you get quotes from a variety of mold remediation companies.

Plus, here’s how to detox naturally to eliminate mold from your body:

  • Use binders and sequestering agents such as activated charcoal, bentonite clay, chlorella, zeolite, and cholestyramine bind to mycotoxins and remove them. They also help to prevent the reabsorption of mycotoxins in the gut.
  • Try sauna therapy. It's an excellent way to detox naturally and remove mycotoxins from your body. In fact there is research showing that orchatoxin is excreted through sweat.
  • Take glutathione is a powerful antioxidant that helps support detoxification pathways, and can be used in conjunction with saunas to help mobilize and remove mycotoxins. If taken orally, 1 tsp a day (450 mg) will suffice. It can be administered intravenously as well.
  • Take probiotics like Lactobacillus rhamnosus which can degrade or bind certain species of aflatoxin.
  • Make sure other yeasts in the body such as Candida are under control. Sometimes it’s necessary to use systemic herbal antifungals to reduce yeast and mold counts
  • Avoid high mycotoxin content foods like grains (corn, wheat), chocolate, wine, coffee, beer, cheese, sugar, and peanuts. I personally believe that when people react to wine it’s not the sulphite content, but rather the mycotoxin content, that causes a headache or fatigue to kick in.
  • Exercise in any form will increase blood flow throughout the body and increase the mobilization of mycotoxins from fat stores.
  • Use a HEPA air purifier to remove mold spores from the air, and reduce the overall toxic burden.
  • Use a dehumidifier to remove moisture from the air. It can especially make a difference in a damp environment like a basement.

Finally, if you are chronically ill and going from doctor to doctor with symptoms, and conventional medicine just can’t figure it out—three things should come to mind: chronic undiagnosed Lyme disease, overexposure to electromagnetics (“electropollution exposure”), and undiagnosed mold. It could be any one of the above, or a combination of all three, that’s making you ill.

Now it’s your turn: Have you ever been troubled by the health effects of mold?
