An allergy occurs when your body’s immune system responds to a harmless substance (allergen) similarly to how it would attack a germ or pathogen. In the presence of an allergen, your immune system releases an antibody called Immunoglobulin E (IgE), which causes cells to release chemicals that can irritate the skin, nose, sinuses, throat, lungs, and sometimes stomach. Symptoms can range from something as small as a stuffy nose, to something as large as a whole-body reaction called anaphylaxis. The most common allergens include pollen, dust, food, insect stings, animal dander, mold, medications and latex. Read More.
