According to the CDC, exposure to moldy environments can lead to a variety of health problems. People with allergies may be more sensitive to mold. Those with immune suppression or underlying lung disease are more susceptible to fungal infections.
Some of the symptoms can be found below.
Some types of mold can cause even more severe symptoms, like lung infections or anaphylaxis (life-threatening symptoms involving lungs). Other types (like black mold) can produce mycotoxins, which are very dangerous and can even be fatal. Your body can absorb mycotoxins through your airways, skin or intestines.
There is believed to be a link between other adverse health effects, such as acute idiopathic pulmonary hemorrhage among infants , memory loss, lethargy, and mold.
There is unfortunately no blood test for mold. Physicians can do allergy testing for a possible allergy to mold, but there are no clinically proven tests that can pinpoint when or where a particular mold exposure took place.
