Glossary Allergens

substances triggering immune responses in sensitive individuals

Allergens are substances that can trigger an allergic reaction in some people. These reactions occur because the immune system mistakenly identifies these usually harmless substances, such as pollen, pet dander, or certain foods, as threats and responds by producing antibodies. This can lead to symptoms like sneezing, itching, or more severe reactions such as anaphylaxis.
