Mold Testing: 10 Most Common Symptoms of Mold Toxicity

mold investigation

Mold toxicity is a serious health concern affecting millions of individuals worldwide. Mold is a type of fungus, and it thrives in damp and poorly ventilated areas, such as bathrooms, basements, and attics. 

While mold spores are everywhere in the environment, certain types of mold can produce toxins known as mycotoxins. These can lead to various health problems when inhaled or ingested. 
In this article, the mold testing & investigation experts at Pure Breathing Solutions reveal the ten most common symptoms of mold toxicity. We’ll explore how they present, how mold causes them, and the importance of mold investigation and testing in explaining these symptoms.

What are the 10 Warning Signs of Mold Toxicity?

  1. Breathing Problems
  2. Persistent Cough
  3. Sinus Infections
  4. Irritated Eyes
  5. Skin Rashes
  6. Headaches & Migraines
  7. Dizziness or Vertigo
  8. Brain Fog or Memory Loss
  9. Ear Infections
  10. Joint Problems

Breathing Problems

Breathing problems can include shortness of breath, wheezing, or asthma-like symptoms, and are often associated with mold toxicity. When mold spores are inhaled, they can irritate the respiratory tract, leading to inflammation and constriction of the airways. 
Mold investigation and testing are crucial in identifying the presence of mold in indoor environments. This allows for remediation to improve air quality and reduce the risk of respiratory issues.

Persistent Cough

A persistent cough that doesn’t seem to go away could be a sign of mold toxicity. Mold spores can trigger irritation in the throat and lungs, which leads to coughing as the body attempts to expel the irritants.

Sinus Infections

Frequent sinus infections or sinus congestion may indicate exposure to mold. Mycotoxins can cause inflammation and increase susceptibility to infections by entering the nasal passages and sinus cavities.

Irritated Eyes

Red, itchy, or watery eyes are common symptoms of mold exposure. Mold can irritate the sensitive tissues of the eyes, causing discomfort and inflammation.

Skin Rashes

Skin rashes or irritation can occur as a result of direct contact with mold or its spores. In sensitive individuals, mold toxins can trigger dermatitis or allergic reactions, such as redness, itching, or hives. Mold testing & investigation can identify the cause of skin problems associated with mold toxicity.

Headaches & Migraines

Chronic headaches or migraines may be linked to exposure to mycotoxins. Mold spores can release volatile organic compounds (VOCs) that contribute to headaches and exacerbate migraine symptoms in susceptible individuals.

Dizziness or Vertigo

Feelings of dizziness or vertigo can occur when mold toxins affect the central nervous system. Mold exposure can disrupt balance and coordination, and induce sensations of spinning or lightheadedness.

Brain Fog or Memory Loss

Brain fog, difficulty concentrating, or memory problems may indicate neurological effects of mold toxicity. Mycotoxins can impair cognitive function and interfere with neurotransmitter activity in the brain, which leads to mental confusion and forgetfulness.

Ear Infections

Recurring ear infections or ear pain could be related to exposure to mold toxins. Mold spores can enter the ear canal and cause inflammation or infection, leading to discomfort and hearing problems.

Joint Problems

Joint pain, stiffness, or inflammation may be symptoms of mold toxicity in some individuals. Mold toxins can trigger an inflammatory response in the body, causing joint discomfort and reduced mobility.
