Question
Do different grasses cause varying amount levels of reaction for hay fever? If so, does it vary by individual which types of grass cause more severe reaction? Is there a way to find out exactly which types of grasses are in the air?
Answer
If you have a grass pollen allergy, you may be allergic to more than one type of grass. There are many types. Only a few are responsible for allergy symptoms, including:
- Bermuda
- Johnson
- Kentucky
- Orchard
- Rye
- Sweet Vernal
- Timothy
Your geographic location can determine which grasses may be responsible for your symptoms. For example, Bermuda grass is typically found in the Southern region of the United States. Timothy grass is typically found in Pennsylvania and New York state.
Finally, the immune response to grass pollen can vary. This depends on environmental factors and genetics. Patients can have different responses to exposure to different grass pollens.
