Allergic rhinitis, commonly known as hay fever, is a type of inflammation in the nose which occurs when the immune system overreacts to allergens in the air. Symptoms include sneezing, runny nose, and itchy, watery eyes. Allergic rhinitis usually occurs during certain times of the year, depending on what allergens are in the air.
What Causes Allergic Rhinitis?
Allergic rhinitis is caused by exposure to environmental allergens. These allergens can come from a variety of sources, including pollen from trees, grass, and weeds; dust mites; animal dander; and mold spores. When a person with allergic rhinitis inhales these allergens, their immune system overreacts and releases chemicals like histamine, which cause the symptoms of allergic rhinitis.
When Does Allergic Rhinitis Occur?
Allergic rhinitis usually occurs during certain times of the year, depending on the allergens that are in the air. For example, if a person is allergic to pollen, they will likely experience symptoms during the spring and summer when pollen levels are highest. Similarly, if a person is allergic to mold, they may experience symptoms in the fall and winter when mold spores are more common.
How Can Allergic Rhinitis Be Treated?
Allergic rhinitis can be treated with a variety of medications, including antihistamines, decongestants, and corticosteroids. In some cases, allergy immunotherapy, or allergy shots, can help reduce the severity of symptoms. It's important to talk to your doctor to determine the best treatment plan for your individual situation.
