Seasonal Allergies – Patient Education Overview
When a person has seasonal allergies, the body’s immune system mistakenly reacts to substances like pollen or mold as invaders. These substances are called allergens. An allergic reaction occurs as the immune system tries to fight off the allergen.
Seasonal allergies affect an estimated 40 to 50 million people in the United States. Read more in our patient education guide.
Seasonal allergies come in several forms:
- Allergic Rhinitis (or hay fever) is an allergy to pollen that is present in the air at certain times of year. Symptoms include itching in the nose, roof of the mouth, throat, and eyes; sneezing; stuffy nose; runny nose; and tearing eyes.
- Eye Allergy (or allergic conjunctivitis) is an allergic reaction to pollen that affects the eyes. Eyes may become watery, itchy, sore, red and/or swollen.
- Mold Allergy is an allergic reaction to mold spores that are present in the air at certain times of year. Symptoms include sneezing; itchy, watery eyes; runny nose; nasal congestion or itchy nose, mouth and lips.
