Those who are exposed to mold regularly over time are more inclined to experience persistent respiratory illnesses like chronic sinusitis and pneumonia.
Chronic fatigue, headaches, memory issues and decreased immune function have also been reported with long-term mold exposure. Some individuals develop an allergy or sensitivity to mold after repeated exposures.
Can mold exposure cause autoimmune disorders?
While more research is still needed, some studies suggest a link between mold exposure and development of certain autoimmune diseases like:
- Multiple sclerosis
- Chronic fatigue syndrome
- Lupus
- Rheumatoid arthritis
The exact mechanism is still being investigated, but one theory is that mold triggers an inflammatory immune response that leads to immune system dysfunction and autoimmunity over time. However, genetics and other factors also play a role in autoimmune disease development.
Can mold exposure affect mental health?
Prolonged mold exposure may also impact mental health and mood, potentially contributing to:
- Depression
- Anxiety
- Mood swings
- Irritability
Some research indicates that mold toxins may have neurological effects that influence mental health. Fatigue and concentration issues from mold can also indirectly affect mood. Those with depression or anxiety may experience worsened symptoms from mold. However, the links between mold and mental health require more studies.
What tests can detect mold exposure and related health effects?
Some tests that may help evaluate mold exposure and effects on health include:
- Allergy testing – Skin or blood test to detect mold allergy
- IgE antibody test – Measures antibodies produced when exposed to mold
- Pulmonary function test – Assesses lung function and airway obstruction
- CT scan of sinuses – Evaluates chronic sinusitis from mold
- Brain MRI – Can detect potential neurological effects in certain cases
- Toxicology testing – Measures mycotoxins and mold byproducts in urine
Allergy testing can identify specific mold allergies that may be contributing to chronic symptoms. IgE antibodies and toxicology testing can provide evidence of mold exposure. CT scans, MRIs and pulmonary function tests may reveal respiratory issues or neurological effects related to mold.
How can you tell if health issues are caused by mold exposure?
Some signs that health problems may be associated with mold exposure include:
- Symptoms improve or resolve when away from the moldy environment
- Symptoms flare up or worsen when in the moldy environment
- Multiple family members experience similar symptoms
- A musty odor is noticeable where symptoms occur
- Evidence of moisture or mold is visible
- Symptoms correspond with seasons when mold levels are higher
If allergy testing confirms a mold allergy, this can also help link symptoms to mold exposure. Consulting a physician who specializes in environmental medicine can help determine if mold is contributing to health issues.
What are some tips for preventing mold growth in the home?
Some tips for preventing mold include:
- Quickly fix any water leaks or flooding
- Use exhaust fans and open windows when showering or cooking
- Clean bathrooms and kitchens regularly with mold-killing products
