Black Mould - Lung Problems

Black mold can multiply and spread throughout the body, causing a plethora of debilitating lung problems and health conditions. Prolonged effects of black mold inhalation can include infections, fungal masses, asthma and allergies. Black mold effects cause permanent lung scarring, tissue damage and deterioration of the breathing passages, leading to long-term respiratory and neurological complications if left untreated.


Asthma is a lower-respiratory, inflammatory disease that can develop or become aggravated when mold is inhaled through the eyes, nose or mouth. Black mold irritates the lungs, causing bronchial spasms that trigger swelling and mucus blockages that obstruct normal breathing. As mucus begins to coat passages, air is blocked from being exhaled and remains in the air sacs, causing asthma symptoms of wheezing, coughing, shortness of breath, chest tightness, sore throat, and asthma attacks as symptoms worsen. Black mold-induced asthma can be treated through doctor-prescribed inhalers, steroids, antihistamines and immunotherapy. Limiting exposure to high concentrations of black mold is effective in decreasing chronic asthma complications.

Allergic Broncho-Pulminary Aspergillosis

Allergic broncho-pulminary aspergillosis is an allergic reaction within the lungs that occurs with the inhalation of black mold fungus, aspergillus. Individuals with asthma or cystic fibrosis are at risk for developing allergic broncho-pulminary aspergillosis due to increased amounts of mucus within the airways. The fungus accumulates in mucus, lining airways and causing chronic inflammation. Symptoms of allergic broncho-pulminary aspergillosis include coughing up blood, wheezing, hacking and asthma attacks. Prolonged exposure to aspergillus black mold can cause permanent scarring of the lungs.

Fungal Infections

Black mold inhalation can lead to serious lung conditions in individuals with damaged lungs due to diseases such as tuberculosis, asthma, cystic fibrosis and emphysema. Aspergillus black mold inhalation can cause respiratory infections, bacterial infections, sinus infections, pneumonia and chronic bronchitis. Aspergillosis infections resulting from black mold in the lungs can be asymptomatic. Those with symptoms may experience coughing up blood, wheezing, fever, chest tightness and constricted breathing.


Aspergillus black mold can develop into aspergilloma, which is a fungal mass of mold fibers, blood clots and white blood cells. Pulmonary aspergilloma typically develops in air spaces within the body that were created by previous lung-damaging diseases. These air cavities fill with fungal balls, causing bleeding in the lungs and long-term tissue deterioration. Invasive aspergilloma spreads throughout the body, affecting the lungs, blood and organs resulting in organ failure, severe discomfort and death, if left untreated. Surgery and anti-fungal medications are recommended for individuals experiencing progressive aspergillosis or aspergilloma.


Black mold is an environmental inhalant, entering the body through the eyes, nose or mouth. Black mold thrives in moisture and homes with little ventilation. Detecting and treating mold within a home or building can reduce symptoms of allergies and asthma and can be effective in preventing serious lung problems.


By lowering relative humidity levels through controlled mechanical ventilation, mould will be unable to survive. The mould will stop growing and begin to die within a matter of days. With the correct removal of the mould spores, your home will never experience black mould again.
