Allergic rhinitis, or hay fever, is an allergic reaction to airborne allergens that cause a collection of symptoms, primarily in the nose and eyes, according to the McKinley Health Center. Because allergic rhinitis causes the sinuses to becoming inflamed, it can lead to reoccurring sinus infections, or sinusitis. A sinus infection caused by allergic rhinitis is treated by addressing the allergies causing the initial reaction, which alleviates sinus inflammation and congestion. An allergist can determine the best approach for treatment.
Allergy Cause
Allergens are substances that trigger allergy symptoms, according to MedlinePlus. Hay fever is caused by airborne substances such as plant pollens, mold spores, dust mites and animal dander. These allergens cause the immune system to produce antibodies, which trigger the release of histamine, leading to common allergy symptoms, such as nasal discharge, sneezing and irritated eyes.
Sinusitis Cause
MayoClinic.com states that sinusitis from allergic rhinitis is a common complication. The sinus cavity becomes swollen due to the allergic reaction, trapping mucus in the sinus cavity. The trapped mucus creates a perfect environment for the growth of bacteria and viruses, which cause the sinus infection.
Symptoms
Common symptoms of sinusitis caused by allergic rhinitis are a combination of both conditions. Allergic rhinitis symptoms include clear, thin nasal discharge, sinus pressure headaches, excessive sneezing, watery eyes, itchy throat and nasal congestion. Sinusitis symptoms include a thick, discolored nasal discharge, a low-grade fever and severe sinus headaches. Facial sensitivity is felt in the eyes, cheekbones and inner ear.
Treatment
According to the McKinley Health Center, treatment for allergic rhinitis includes the use of antihistamines, corticosteroid nasal sprays and immunotherapy. These treatments are intended to manage allergy symptoms and reduce inflammation in the sinuses. Before using any medication to treat hay fever or sinusitis, talk with a doctor. A sinus infection may require prescribed antibiotics and the use of over-the-counter drugs such as decongestants and pain relievers.
Prevention
To prevent a sinus infection from hay fever, avoid exposure to allergens. The McKinley Health Center states that an allergy cannot be prevented, but the reaction can. Identify allergens by participating in allergy testing with an allergist. Avoid going outdoors during springtime, keep a clean, dust-free home and stay away from animals. Exercise and drinking at least eight 8-ounce glasses of water daily can also help prevent a sinus infection from allergic rhinitis.
