Allergies are a condition in which the immune system overreacts when it is exposed to specific allergic triggers. In the case of mold allergies, allergic triggers are mold spores. When small, airborne mold spores are inhaled by mold-allergic individuals. The body identifies the spores as harmful foreign bodies. In response, an allergic reaction starts and the body releases histamine, the chemical that is responsible for the unpleasant symptoms you begin to experience. Mold is found both indoors and outdoors. Outdoor molds usually cause allergy symptoms in summer and fall, while indoor molds may cause symptoms year-round. There are many types of mold, but only certain kinds cause allergies – the most common of these are alternaria, cladosporium, aspergillus, and penicillium. Some mold spores can spread in dry, windy areas. Others spread when the humidity is high. After the first exposure, antibodies continue to recognize mold as a trespasser, so any further contact with the mold will cause the immune system to respond with further allergic reactions. There are some allergic conditions that are caused by mold. If you experience these conditions, you may be allergic to mold and should seek treatment immediately. Allergic Conditions Caused by Mold Asthma – shortness of breath, chest tightness, and coughAllergic fungal sinusitis – when fungus begins to grow in the sinusesAllergic bronchopulmonary aspergillosis – a fungal infection in the lungs that may occur in people who also suffer from asthmaHypersensitivity pneumonitis – a rare inflammation of the lungs caused by exposure to airborne mold spores or dust.

Mold allergy symptoms differ from one person to the next and can be mild or severe, causing asthma attacks. They can be year-round or erupt only at particular times of the year. Symptoms may be worse with damp weather or in places that have high levels of mold spores. Risk Factors for Mold Allergies Several risk factors can lead to the development of a mold allergy or aggravate symptoms you are currently experiencing: Family history of allergies and/or asthmaBeing exposed to mold while you are at work (working outdoors in moist environments, working with plants, or even baking and furniture repair)Living or working in a building where mold can thriveHumidity of 60% or moreLeaky pipes or water damagePoor ventilation in damp areas, like basements and bathrooms Mold Allergy Diagnosis To properly diagnose an allergy to mold, a physical examination will be performed and a full medical history will be taken by one of our board-certified allergists. It is also likely that you will need allergy skin prick testing. This test uses diluted amounts of allergens that are applied to the skin with tiny punctures. If you are allergic, you will have a localized allergic reaction and a raised bump (hive) will develop on your skin. Skin prick testing is the most common method of allergy testing. It takes less than 20 minutes for results to show. You will experience some itching during the test while the allergens are reacting, but it will subside shortly. Your allergist will monitor you for more severe symptoms that may arise. This test is not recommended for those with ongoing skin conditions, such as eczema. In this case, an allergist may use an allergy blood test to diagnose a mold allergy. Blood tests measure immunoglobulin E (IgE), an antibody that your immune system develops in reaction to a specific allergen. They are usually accurate but take longer to deliver results.
