Mold Toxicity is a Common Cause of Chronic Conditions

Hi there,

Mold toxicity isn’t normally explored by conventional doctors and therefore often missed as a cause of chronic illness. I routinely find that many of my chronically ill patients have in fact been exposed to mold toxins, sometimes decades ago. This exposure can be from a current or past home or office. Mold toxins can trigger all sorts of unwanted symptoms. The same symptoms that plaque those with a chronic illness, like those with fibromyalgia, Long COVID, ME, and autoimmune conditions including Hashimoto’s thyroiditis, and rheumatoid arthritis.

Mold exposure symptoms include:

  1. Fatigue and weakness

  2. Headaches, light sensitivity

  3. Poor memory, difficult word finding

  4. Difficulty concentration

  5. Morning stiffness, joint pain

  6. Unusual skin sensations, tingling, and numbness

  7. Shortness of breath, sinus congestion or a chronic cough

  8. Appetite swings, body temperature regulation,

  9. Increased urinary frequency or increased thirst

  10. Red eyes, blurred vision, sweats, mood swings, sharp pains

  11. Abdominal pain, diarrhea, bloating

  12. Tearing, disorientation, metallic taste in your mouth

  13. Static shocks

  14. Vertigo, feeling lightheaded

Mold is not a plant or an animal, but a type of fungi. We eat some types of fungi, like many kinds of mushrooms and the yeast we use to make bread rise. There are hundreds of different kinds of mold found both indoors and outdoors. Mold grows in damp, dimly-lit areas.

Mold can grow and thrive in any season, indoors or outdoors, in damp, warm and humid environments. Showers, attics, basements, and damp crawlspaces are common areas where you’d find toxic mold.

Mold itself flourishes in warm, moist environments, but mold spores can actually survive in harsh, dry environments. The spores float around in indoor and outdoor air. When spores land on a moist surface, they can then start to grow.

Some molds commonly found indoors include aspergillus, chaetomium, cladosporium, penicillium, and stachybotrys (sometimes referred to as black mold, although many types of mold are black in color).

Mycotoxins are the toxic secondary metabolites produced by molds such as AspergillusFusariumPenicillium, and Stachybotrys and are commonly encountered in water-damaged buildings and contaminated food.

Trichothecenes, fumonisins, ochratoxin, and aflatoxins are the most commonly-encountered harmful mycotoxins.

  • Trichothecenes are produced by Stachybotrys and Fusarium, among other molds. They proliferate in water-damaged buildings.

  • Fumonisins are produced by Fusarium, which commonly grows on corn, wheat, and other grains. Fusariumfungi are quite prevalent in temperate climate conditions.

  • Ochratoxin is produced by Aspergillus and various species of PenicilliumPenicillium often grows in indoor environments on wallpaper, carpet, furniture, and fiberglass insulation. Penicillium also grows on citrus fruits and grains. The main crops contaminated with ochratoxin include grains, nuts, dried fruits, coffee, and cocoa.

  • Aflatoxins are produced by Aspergillus and are thus found on a variety of foods (listed above).

Research reports that 25 percent of the world’s crops, including grains, nuts, wine, spices, and coffee, are contaminated by mycotoxins due to poor harvesting practices, improper food storage, and damp conditions during food transport and processing.
