Allergic rhinitis/hay fever is the inflammation of the nose caused by allergens.
The allergic response occurs in two phases, “early” and “late” phase responses. Early phase occurs within minutes of exposure to the allergen and tends to produce sneezing, itching, and clear rhinorrhea while late phase occurs 4-8 hours after allergen exposure and is characterized by congestion, fatigue, malaise and irritability.
There are approximately 10-30% of adults and 40% of children worldwide affected by allergic rhinitis.
Types of Allergic Rhinitis
Seasonal (due to pollen during spring)
Perennial (due to indoor substances like dust mites & pet dander)
