The sneezing; itchy, watery eyes, and other cold-like symptoms are known as hay fever. But spring allergies have nothing to do with hay or fever. Rather, they are caused by pollen and mold. Pollen comes from grass, trees, or ragweed. Mold grows outdoors in fields and on dead leaves. Pollen and mold are hard to avoid. The American College of Allergy, Asthma and Immunology (ACAAI) says a single ragweed plant can let loose 1 billion tiny pollen grains. There are even more mold spores. They grow all around.What is an allergy?Dr. Michael Foggs, an allergist and president of the ACAAI, 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--about 25 percent of people. An allergic response results 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—the classic symptoms of spring allergies.Diagnosing AllergiesThe first step in checking for allergies is to see a doctor who will take a full history. That involves asking about your life, home, and work environment and 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 causes your allergies, your doctor may suggest over the counter drugs to fight your 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:
