What Is an Allergic Reaction?
An allergic reaction pertains to the immune system's response to a foreign substance known as an allergen. When the body comes upon an allergen, it produces immunoglobulin E (IgE) antibodies. These antibodies then attach to mast cells located in body tissues such as the lungs, nose, and eyes. The IgE antibodies are what the allergen attaches to when it is met again. As a result, histamine and other substances are released into the circulation by the mast cells. These chemicals can provoke various symptoms, such as a runny nose, sneezing, and itchy eyes.Why do Allergic Reactions happen?
