Depending on what type of mold is growing in your home, mold can pose a hazard for lung problems for anyone. With the most toxic molds, even the healthiest people can quite easily become ill. People with weakened immune systems are, however, at a much higher risk for lung problems due to mold, and if they acquire a lung problem, it can be much more severe.
For people who are undergoing chemotherapy, or taking immunosuppressant drugs or have a weakened immune system for another reason face a much greater risk of mold-related lung problems and infections. A lung infection called Bronchopulmonary Aspergillosis can develop. If this particular lung condition develops, the mold grows within the lungs. The mold then provides a constant source of irritation and allergy-like symptoms.
Another potential lung problem is Pneumonitis. This condition is characterized by swollen or inflamed lung tissue, and often caused by exposure to mold spores. Some symptoms include fever, coughing, and shortness of breath.
While little conclusive evidence exists linking Pulmonary Hemorrhage to mold, this is the worst of the lung conditions potentially caused by mold exposure. The evidence that bleeding of the lungs is tied to exposure to black mold is somewhat limited, but many claim that the condition is caused by black mold. Mainly adults with compromised immune systems and infants are affected.
If you have mold in your home, it will not necessarily make you sick, but if you have a compromised immune system, you are at higher risk than a healthy individual. It is important that you keep your home dry to prevent the growth of dangerous mold and bacteria. If you have a damp home, consult with professionals to correct the problem at the source.
