Unexplained fatigue, brain fog, or respiratory issues can sometimes be linked to mold exposure, especially in damp or poorly ventilated environments. Common symptoms include coughing, wheezing, sinus congestion, headaches, skin irritation, and worsening asthma or allergies. While “mold toxicity” is debated, doctors may evaluate exposure through medical history, allergy testing, blood tests (for immune response), and sometimes urine tests for mycotoxins, along with environmental assessments of your home. If symptoms persist, it’s important to address potential mold sources (cleaning or remediation) and consult a healthcare professional or specialist to identify the cause and guide proper treatment.
