If you have allergies, you may be surprised to learn that you weren\u2019t born with them. Instead, you developed the condition when your immune system first came into contact with a triggering allergen. We review how this occurs below.<\/p>\n\n\n\n

It Starts with the Immune System<\/h2>\n\n\n\n

The immune system\u2019s job is to protect our bodies from infections, diseases and toxic substances. As molecules enter the body via the eyes, nose, mouth or skin, the immune system deems them either harmless or threatening.<\/p>\n\n\n\n

If a substance is considered harmless, the body accepts it, which is known as a Type 1 immune response. The T cell is responsible for this process. However, if an allergen is labeled a threat, the body responds with a Type 2 immune response. This involves a T helper type 2 cell.<\/p>\n\n\n\n

What Is Allergic Sensitization?<\/h2>\n\n\n\n

The first time your body is exposed to an allergen<\/a> that produces a Type 2 response, it is known as allergic<\/a> sensitization. This means the body keeps a lasting memory of the substance. When it comes into contact with the allergen in the future, IgE molecules release the inflammatory chemical histamine. Histamine causes inflammation, mucus production and itching.<\/p>\n\n\n\n

Types of Allergic Responses<\/h2>\n\n\n\n

Allergies can manifest in a number of ways, including:<\/p>\n\n\n\n
