Mold is a type of fungus that is found both indoors and outdoors. It can grow on almost any surface, including wood, paper, carpet, and food. When mold spores are present in the air, they can cause allergic reactions in some people.
Mold and asthma are often linked because exposure to mold can trigger asthma symptoms. In fact, mold is one of the most common indoor allergens. People with asthma are especially sensitive to mold and may have more severe reactions.
Mold can cause asthma attacks and make asthma symptoms worse. If you have asthma, it’s important to avoid exposure to mold. If you’re allergic to mold, you may also be at risk for other allergies and respiratory problems.
If you think you’re allergic to mold, see your doctor. He or she can give you a skin test or blood test to find out. If you’re allergic to mold, you can take steps to avoid exposure and keep your asthma under control.
