Allergic Rhinitis is commonly known as hay fever. It is an allergic disorder caused due to the reaction of our body when it comes in direct contact with things called allergens. The symptoms include sneezing, coughing, itching (mostly in eyes, mouth, throat, nose, and skin), runny/stuffy nose, headache, sore throat, etc. This disorder develops when the immune system of our body becomes overly sensitive and reacts to something that is in the environment and generally not harmful to people. There are mainly two forms of allergic rhinitis.
A) Seasonal AR (Hay Fever): This can be caused by allergy to pollen grains or mould spores in the air. When pollens are carried by air in spring, late summer or in fall then people might come in contact with them and start showing symptoms of rhinitis.
B) Perennial AR: This is not seasonal as it can be caused by more common allergens in the air like dust, smoke, dust mites, pet hair or dander. These allergens are found in the air all year long and thus become chronic or happen frequently to people.
