Allergic rhinitis, commonly known as hay fever, is an allergic reaction that affects the nose and upper respiratory system. It occurs when the immune system overreacts to airborne allergens such as pollen, dust mites, mold, or pet dander, leading to inflammation and irritation in the nasal passages. This condition is characterized by symptoms like sneezing, runny or stuffy nose, itchy eyes, and throat irritation. Allergic rhinitis can be seasonal (occurring during certain times of the year) or perennial (year-round).
If your symptoms of allergic rhinitis persist, worsen, or interfere with daily activities, it’s important to consult a healthcare professional. Early diagnosis and proper management can help reduce symptoms, improve quality of life, and prevent the development of other allergic conditions, such as asthma.
Types of Allergic Rhinitis
- Seasonal Allergic Rhinitis: Often triggered by pollen from trees, grasses, or weeds, seasonal rhinitis typically occurs during the spring, summer, or fall.
- Perennial Allergic Rhinitis: This form occurs year-round and is often caused by dust mites, pet dander, or mold. It tends to be less affected by the changing seasons and can persist for long periods.

Causes and Risk Factors of Allergic Rhinitis
The main cause of allergic rhinitis is an immune system response to specific allergens. When the immune system encounters an allergen, it releases histamines and other chemicals, leading to inflammation and the typical symptoms of rhinitis. Risk factors for developing allergic rhinitis include:
- Family history: A genetic predisposition to allergies increases the likelihood of developing allergic rhinitis.
- Exposure to allergens: Living in environments with high exposure to allergens like pollen, dust mites, or pet dander increases the risk.
- Other allergic conditions: Individuals with a history of eczema, asthma, or other allergies are more likely to develop allergic rhinitis.
- Environmental factors: Air pollution, smoking, or living in urban areas with high allergen exposure may contribute to the development of allergic rhinitis.
