Allergies start when your immune system mistakenly identifies a harmless substance as a threat.
Understanding the Allergic Reaction
An allergic reaction is fundamentally a response by your body's immune system. Here's a breakdown of how it occurs:
- The Misidentification: The process begins when your immune system encounters a normally harmless substance. This substance is known as an allergen and could be anything from dust, mold, or pollen.
- The Overreaction: In a person with allergies, the immune system overreacts to this allergen.
- Antibody Production: The immune system produces specific antibodies designed to "attack" the allergen. According to the provided reference, these antibodies are produced as part of the immune system's overreaction to the allergen.
