Yes, it is possible to suddenly develop allergic rhinitis. Allergic rhinitis is an inflammation of the nasal passages that occurs when the body comes into contact with an allergen. When the allergen is inhaled, it triggers an immune response that causes the release of histamine and other chemicals, leading to symptoms such as sneezing, a runny nose, and itchy, watery eyes.
What Causes Allergic Rhinitis?
Allergic rhinitis is most often caused by airborne allergens such as pollen, dust mites, animal dander, and mold. These allergens can trigger an allergic reaction when they come into contact with the mucous membranes in the nose.
Are There Risk Factors?
People with a family history of allergies, such as hay fever or asthma, are more likely to develop allergic rhinitis. Other risk factors include living in a highly polluted area, being exposed to secondhand smoke, and being around pets or other animals.
Symptoms of Allergic Rhinitis
The most common symptoms of allergic rhinitis are sneezing, itchy eyes, a runny nose, and congestion. Other symptoms may include a sore throat, fatigue, and difficulty sleeping.
Diagnosis and Treatment
Allergic rhinitis is usually diagnosed based on a patient's symptoms and medical history. If the diagnosis is unclear, a skin prick test or an allergy blood test may be used to determine the cause of the allergic reaction.
Treatment for allergic rhinitis typically includes avoiding the allergen, using over-the-counter or prescription medications, and using allergy shots to build up a tolerance to the allergen.
