Allergic rhinitis, commonly known as hay fever, is a condition characterized by inflammation of the nasal passages due to an allergic reaction. Signs of allergic rhinitis include sneezing, an itchy and runny nose, congestion, and itchy and watery eyes. Additionally, people with allergic rhinitis may experience headaches, fatigue, and trouble sleeping due to difficulty breathing. These symptoms can occur seasonally or year-round depending on the cause of the allergy. It is important to consult with a healthcare provider if you suspect you have allergic rhinitis, as they can help determine the cause and recommend appropriate treatment options.
