Mold allergies

Mold may be the cause of allergies that get worse in damp weather. Mold produces spores that move, such as pollen, in outdoor air during warmer months. People allergic to molds may have symptoms from spring to late fall. The mold season peaks from July to late summer.

Researchers are studying the effect of indoor mold on health. It may be a trigger for people with allergic asthma. Visit the Minnesota Department of Health’s Web site for more information about indoor mold.

Symptoms

Because they are so small, mold spores may evade the protective mechanisms of the nose and upper respiratory tract to reach the lungs. Mold allergies can trigger asthma, with symptoms of wheezing, cough and shortness of breath.   Other symptoms may include: sneezing runny nose nasal congestion coughing itchy, watery eyes

Diagnosing

Your doctor will use your medical history, a physical exam and skin testing to determine if you have mold allergies.

Treatment

Avoiding contact with mold spores is the best way to prevent an allergic reaction. Medications including antihistamines and decongestants can help relieve symptoms.
