Allergic rhinitis
commonly known as hay fever, is an allergic reaction that occurs when your immune system overreacts to allergens in the air. Here are some key points about it:
Symptoms
- Sneezing
- Runny or stuffy nose
- Itchy eyes, nose, or throat
- Postnasal drip
- Cough
- Fatigue
Causes
Allergic rhinitis can be triggered by various allergens, including:
- Pollen from trees, grasses, and weeds
- Dust mites
- Mold spores
- Pet dander
Types
- Seasonal Allergic Rhinitis: Occurs at specific times of the year, usually in spring and fall due to pollen.
- Perennial Allergic Rhinitis: Occurs year-round, often triggered by dust mites, pet dander, or mold.
Diagnosis
Diagnosis typically involves:
- Medical history review
- Physical examination
- Allergy tests (skin prick tests or blood tests)
Treatment
- Avoiding triggers
- Antihistamines: Help relieve symptoms.
- Nasal corticosteroids: Reduce inflammation.
- Decongestants: Alleviate nasal congestion.
- Immunotherapy: Allergy shots that gradually desensitize the immune system.
Prevention
- Keep windows closed during high pollen seasons.
- Use air purifiers and dehumidifiers.
- Regularly clean bedding and carpets to reduce dust mites.
If you suspect you have allergic rhinitis, consulting with a healthcare professional is recommended for proper diagnosis and management.
