Pollen Allergy: Overview


Pollen from trees, grasses, and weeds can be inhaled and cause allergy and asthma symptoms. Pollen may travel many miles in the wind, so trees, grasses, and weeds beyond your immediate area can cause allergy and asthma symptoms. Pollen allergies are often seasonal, and allergy and asthma symptoms occur when the amount of pollen in the air is high. Examples of allergy symptoms include itchy eyes, runny nose, and sneezing. This may vary depending on weather conditions and where you live.

Once an allergy has been identified, your healthcare provider may recommend medications or therapies to control symptoms. The next step is to decrease or eliminate exposure to the allergen. This is called environmental control. Evidence shows that allergy and asthma symptoms may improve over time if the recommended environmental control changes are made.
