Mold Toxicity Symptoms, Diagnosis and Natural Treatment

The awareness of mold toxicity and it’s effect on human health has increased dramatically over the past few years. Estimates predict that indoor air pollutants, including mold, may be contributing to more than 50% of people’s illnesses.

You will find the most common types of mold indoors, which include Cladosporium, Penicillium, Alternaria, and Aspergillus. Stachybotrys chartarum sometimes referred to as “toxic black mold”, grows on household surfaces such as wood, fiberboard, gypsum board, paper, dust, and lint.

Read on to learn more about the typical symptoms of mold toxicity, diagnosis and testing and a simple but an effective natural treatment approach.

3 Most Common Symptoms of Mold Toxicity

Mold toxicity can cause a multitude of different symptoms. Three however common symptoms are almost always present.

  1. Fatigue – by far the number one symptom.
  2. Cognition issues including memory, word finding and calculation difficulties.
  3. Breathing issues including chronic sinus congestion, shortness of breath, breathing difficulty with exercise, sinus nasal drainage, and wheezing. The wheezing looks like asthma, but it doesn’t respond to the typical treatment of inhalers.

Other symptoms of mold toxicity may include:

  • Musculoskeletal symptoms including muscle weakness, achiness, joint pain, and morning stiffness.
  • Urinary symptoms including urinary incontinence, increased thirst, and electrolyte abnormalities leading to muscle cramps.
  • Neurological symptoms including numbness, tingling, and unusual skin sensation where one side of the face becomes numb or even paralysed.
  • Digestive problems including loose stools.
  • Vision issues including red eyes and blurry vision. Sometimes, patients will have night sweats.
  • General symptoms might include sudden appetite swings, body temperature changes, and weight gain, especially in women.

Mold toxicity can produce some unusual symptoms including:

  • Ice pick pain – A sharp, stabbing pain that can be anywhere in the body, but it’s frequently in the head. A headache that feels like being stuck with an ice pick.
  • Static shocks
  • People with mold toxicity often complain about the watches they wear stop working for no apparent reason.

How To Diagnose Mold Toxicity

Like any disease, you can diagnose mold toxicity from a combination of presenting symptoms, good case history and testing.

If you suspect you may have mold toxicity, then some fundamental questions may give you clues that mold might be a problem.

  • Do you live in a moldy house?
  • Do you live in a building that has had water intrusion, damp basement, or musty smells?”
  • Do you get condensation on the windows?
  • Does your house have a flat roof?
  • Did you develop this illness after a move to a new location or got a new job?
  • Do you feel better when you’re on vacation?
  • Do you smell a musty odour anywhere in your house or place of work?

Testing For Mold Toxicity

When investigating mold toxicity, there are two types of testing you should consider, environmental and lab testing.

For environmental testing of your home or workplace, you can do a formal test with a mold inspector. Alternatively, you can do a DIY home test called an EMRI. You can order the EMRI test on This test looks for the DNA of mold in the house dust.

Lab testing

When testing for mold toxicity, it is not necessary to spend many thousands of dollars on lab testing. Rather the cost of testing should be below $1000. Below are a couple of the lab markers, that you should consider when looking for mold toxicity.

  1. HLA-DR typing, gene testing that will tell you if you are within 24% of the population that is genetically susceptible to mold toxicity.
  2. TGF-beta, a marker of an overactive immune system.

A combination of the above testing is available through a direct patient lab called Life Extension.

A 3 Step Natural Treatment Plan For Mold Toxicity

1. Get out of exposure

If you have come to the firm conclusion that you have mold toxicity, then you should remove yourself from the mold exposure environment. If you try any treatment and you are still in a moldy environment, the therapy will not help.

By removing yourself from the environment, there is a good chance you will begin to feel better. If you do not feel better this does not mean that mold is not the problem. A small percentage people with mold issues still feel unwell after removing themselves from the source of the exposure. These people have a condition known as Chronic Inflammatory Response Syndrome (CIRS). People with CIRS often have the genes that make them highly susceptible to mold exposure. Research has shown that 24% of the population have some risk to mold exposure while 4% have a very high risk.

2. Identify and remove the mold from your environment

Once you have removed yourself from the environment, the next step is to identify and remove the mold from your home or workplace. If you can remove the mold, this may be all you need to do to feel better. Again any improvement will be closely associated with your genetics. The worse your genes, the less chance you will feel better from just removing the mold.

3. Remove the mold from the body

The next step is to begin the process of removing the mold from your body. One of the main ways you can detox your body from the mold is through the use of bile sequestrants.

How acid sequestrants work

When the body is exposed to toxins, it detoxifies them through the liver and then secretes them into the bile where they go out via the stool. In some people with mold toxicity bile is reabsorbed back into the body. Bile acid sequestrants are compounds that bind to bile acids, stopping reabsorption and allowing them to pass out of the body in the stool.

There are two types of bile acid sequestrants, prescription and natural compounds.

Prescription Bile Sequestrants

The bile prescription sequestrants that have been studied the most are Cholestyramine powder and Welchol.

The recommended dosage for Cholestyramine powder is 4 grams, four times a day, an hour before a meal or supplements or two hours after.

Welchol is taken once or twice a day. Welchol is not as efficient and is more expensive then Cholestyramine powder.

For best results when I recommend combining the prescription binders with clay, charcoal, chlorella, and glucomannan.

Natural Bile Sequestrants and binders

Warning: People with severe intractable diarrhea cannot tolerate bile sequestrants.

Tracking treatment progress

An easy way to monitor the effectiveness of treatment is to use a visual contrast study (VAS) that can be done in the office or online. A VAS detects retinal changes to capillary hypoxia. If the test is abnormal, it is likely that there has been a toxic exposure.

  2. Thank you for sharing!

    1. My pleasure!

  3. Thank you for sharing!
    I live with every one of these symptoms daily + chronic active EBV. It’s been a challenge but am glad to see that practioners are more and more understanding this disease

    1. My pleasure, Josiane.

  4. Thanks for the article. How would I go about getting lab testing for mold here in Ottawa? I see that Life extension lab is American.

    1. Hi JP, I cannot access mould blood testing here in Ottawa. As an alternative, I use muscle response testing to test my clients for mould sensitivity or toxicity. I am not sure if Naturopathic Doctors have access. Kind regards Domnick
