What causes an allergy to sunflower seeds?
An allergy to sunflower seeds, or seeds in general, is uncommon. However, some hypersensitive individuals have reported adverse reactions to sunflower seeds. Allergies to sunflowers or sunflower seeds are most common among bird breeders or individuals that work closely with seed harvesting. Due to cross-reactivity, individuals with tree nut allergies may also experience an adverse reaction to sunflower seeds. Sunflower seeds and tree nuts share two key allergens: Hel a 3, a lipid transfer protein (LTP), and Hel a 2, a profilin protein. Upon ingestion, the body views these allergens as harmful and produces IgE antibodies to combat the invaders. Unfortunately, these antibodies cause the release of a chemical called histamine, triggering an allergic reaction.
When should I order a Sunflower Seed Allergy IgE Blood Test?
Individuals may order this test if they have experienced the symptoms related to a sunflower seed allergy. An allergic reaction may range from mild or moderate to severe and vary for each individual. An individual may experience allergic reaction minutes to a few hours after exposure to an allergen. An individual allergic to sunflower seeds may experience the following symptoms:
- Tingling sensation in or around the mouth
- Swelling
- Abdominal pain
- Nausea or vomiting
- Diarrhea
- Itching, hives, or eczema
- Congestion
- Trouble breathing or wheezing
- Lightheadedness
An extreme, possibly life-threatening allergic reaction is known as anaphylaxis and can occur in the most severe cases. An anaphylactic response requires immediate medical attention. Signs or symptoms of anaphylaxis include:
- Rapid or increased pulse
- Swollen throat or lump making it difficult to breathe
- Low blood pressure
- Extreme dizziness or loss of consciousness
