About 75% of people with asthma also have allergic rhinitis (hay fever), and about 25% of people with allergic rhinitis also have allergic asthma.
Allergens such as pollen can trigger asthma as well as allergic rhinitis symptoms. Many people with allergic rhinitis due to grass pollen allergy can get allergic asthma in spring and summer when they also have allergic rhinitis.
Better control of allergic rhinitis results in better asthma control in both adults and children. Untreated allergic rhinitis may also increase the risk of developing allergic asthma.
If you have allergic rhinitis and asthma, it is important to have both an ASCIA Allergic Rhinitis Treatment Plan and an Asthma Plan.
