Hay Fever

Hay fever (pollen allergy) is one of the most common kinds of allergies. About 35 million Americans suffer from hay fever. Pollen is made by trees, grasses, and weeds. During the spring, summer, and fall some plants release pollen into the air you breathe. Your symptoms might be different at different times of the year. It all depends on the kinds of plants that grow where you live and what allergies you have.

Symptoms of Hay Fever

  • Sneezing
  • Runny or clogged nose
  • Coughing
  • Itchy eyes, nose, and throat
  • Watery eyes
  • Red, swollen eyes
Why do some people have allergies and hay fever?
No one is sure what causes allergies. You are more likely to have hay fever if your parents have it.

What kinds of tests check for allergies?
  • Skin tests--Your doctor may also use a needle to put a small amount of allergen into your skin. After a few minutes, the reaction tells your doctor if you have allergies.
  • Blood tests--Your doctor may use a blood test to look for a protein in your blood called IgE. This protein is made by people with allergies and hay fever. It also helps fight certain types of infection.
Both tests look for certain disease-fighting cells (antibodies). Your body makes these cells to match whatever it is fighting. Your antibodies tell doctors what you are allergic to.

How are allergies and hay fever treated?
Your doctor can help you decide what to do. You can:
  • Avoid the things that cause your symptoms.
  • Use medicines.
  • Get allergy shots.
Allergy shots contain small amounts of what you are allergic to. At first, shots may be given every week to lessen your symptoms. The shots are usually continued for 3 to 5 years.
