Allergies are a very common chronic condition among Americans. More than 7% of the adult population is diagnosed with hay fever every year, which is the common name for allergic rhinitis. In the spring, hay fever is often caused by various types of tree pollen, grass, and weeds.
An allergy is the immune system’s hypersensitivity reaction to usually harmless substances in the environment. If the body is allergic to food, most symptoms occur around the mouth, throat, or stomach. If the allergen is something a person breathes in, the symptoms are then likely to affect the eyes, nose, and lungs.
