Mold Exposure Symptoms Described by Our Functional Medicine Toronto Practice


Mold-related health issues can cause an array of health effects – did you know these can be addressed at our functional medicine Toronto clinic?  

There are likely millions of mold species on this planet; and every day and everywhere, this exposure may trigger long-term health issues. Consequently, this might pose various health risks, such as disrupting bodily functions, skin, cognition, digestion, mental health, and more. “Molds produce allergens (substances that can cause allergic reactions) and irritants. Inhaling or touching mold or mold spores may cause allergic reactions in sensitive individuals,” confirms the United States Environmental Protection Agency.

Not everyone has the same reaction to mold though, as exposure can cause individual symptoms. Some might experience sniffles from mild contact; others may have severe shortness of breath from regular exposure. Consistent exposure to mold could trigger a chronic illness down the road. In one study on children, it was shown that asthma in kids ages 3-17 was linked to household mold. This is discerning, as this age group tends to spend 90% of their free time within indoor settings. 

Mold spores are concealed indoors and outdoors, and we don’t always know when they’re lurking – overgrowth can happen in your ceilings, window panes, food, walls and fabrics! So, what can we do to prevent or treat mold-related illnesses? First, education is key. Here, we provide a brief guide to mold and the symptoms associated with exposures. 

Quick Guide to Mold Toxicities

Scientists break down mold into allergenic, pathogenic and toxigenic categories. 

Toxigenic molds can create mycotoxins (toxins specifically created by mold), and these can be absorbed via inhalation or by consuming/touching them; mycotoxins tend to be correlated with low immune function, neurological disorders, hepatoxicity and nephrotoxicity.  

Even when people are already in good health, pathogenic molds can still cause infections. In fact, pathogenic molds can initiate severe health concerns, especially in immunocompromised individuals; sinus and digestive tract infections, as well as skin and lung infections, could result. 

And finally, allergenic mold can be alarming if you’re already susceptible to mold allergies. Your immune system may be sensitive to particular mold spores, and may identify these spores as allergens; thus symptoms like sneezing, watery eyes, runny nose, itching and nasal congestion may be instigated. 

So what are some of the common molds found indoors? Refer to the following table for details:

Type of Mold
Penicillium sp.

This species is known to hide in wallpaper, carpet, insulation, or old fabrics. Mycotoxins are occasionally formed; known to be the root cause of asthma and mild allergic reactions.

Aspergillus sp.

Known to instigate lung infections, this is commonly found in damp, dusty areas of the home. Sometimes mycotoxins are produced from this species.

Black mold
Considered toxic because mycotoxins are produced, and they can trigger serious respiratory health issues. Black mold can be found in wood or paper items around the home.

Understanding mold and their impact on wellness may help prevent chronic disease related to it. Below, we highlight some markers for mold exposure: 

13 Symptoms of Mold Exposure

  1. Cognitive concerns (i.e. brain fog, memory loss, concentration issues).

  2. Vertigo

  3. Increased thirst and urination

  4. Troubling regulating body temperature

  5. Unexplained fatigue

  6. Perplexing body aches (i.e. muscle, joint and nerve pain)

  7. Tremors/involuntary movements

  8. Sensitivity to light, red eyes

  9. Tastes in your mouth that resemble metal

  10. Digestive troubles (i.e. abdominal pain, diarrhea, nausea)

  11. Respiratory concerns (i.e. coughing, asthma, wheezing, congestion, runny nose)

  12. Skin rashes

  13. Sneezing

Have you been exposed to mold? Our functional medicine practitioners can recommend lab tests to see if you’ve had contact with that or other environmental factors. We can provide an exposure profile to test for 40 species; genetic testing may also confirm if you’re susceptible to mold-related conditions. After analyzing your lab results, our healthcare providers can make suitable recommendations for functional medicine treatments. Some therapies may include medications, herbal extracts, essential oils, and binders to help lessen toxicities and treat this fungal growth in the body. 

Our integrative approach to health can be applied to various health concerns regarding mold and other toxicities, nutritional deficiencies, heart disease, chronic pain, hormone imbalances, sexual health, sleep issues, adrenal fatigue, and infertility. Please don’t hesitate to reach the Toronto Functional Medicine Centre for assistance.
