Hay fever can manifest itself as sneezing, itchy/watery eyes and other cold-like symptoms. But spring allergies have nothing to do with hay or fever, but are caused by pollen and mold. Mold grows outdoors in fields and on dead leaves. Pollen comes from grass, trees, and ragweed. Pollen and mold can be hard to avoid, especially when spring comes and the weather is beautiful and crisp. The American College of Allergy, Asthma and Immunology (ACAAI) says a single ragweed plant can let loose 1 billion tiny pollen grains. And mold spores are even more prevalent, as they grow everywhere.What is an allergy?Allergist and president of the ACAAI, Dr. Michael Foggs says we all have an allergy protein in our bodies and we all breathe in pollen and mold. Pollen and mold are forms of “allergens” which means they can cause an allergic reaction in those who are sensitive to those allergens, which is about 25% of people. An allergic response happens when a protein in the blood called immunoglobin E (rIgE) releases a chemical called histamine.Histamine tightens small blood vessels of the nose, making fluids leak out into other tissues. This causes noses to run, eyes to water, and skin to itch and swell—all classic symptoms of spring allergies.Diagnosing AllergiesThe first step is to give your doctor a full history of your health. This will involve details about your life, home and work environment, as well as your eating habits. The doctor is looking for clues as to which “allergen” may be causing your spring allergies. Your doctor may test for allergies by placing small amounts of common allergens on your skin, usually on your forearm or back. If you are allergic, your skin will become red, swollen, or itchy. Once you know what’s causing your allergies, your doctor may suggest over the counter medications to fight your symptoms (runny nose, sneezing, and itching). Allergy drugs come in tablets, nose sprays, eye drops, and liquid form. In some cases, the doctor might suggest allergy shots. Limit Your ExposureLimiting exposure to the allergens also can help reduce symptoms. The ACAAI suggests these:
