How Do Allergies Develop?

The World Allergy Organization (WAO) warn that “the prevalence of allergic diseases worldwide is rising dramatically in both developed and developing countries.”

Allergens are everywhere in our environment, and can come in the form of tree pollen, food, mold, dust mites, snake or insect venom, and animals, such as cats, dogs, and cockroaches. When an allergy develops, the body mistakes one of these substances as a threat and hence reacts with the body’s immune system.

One fact that people don’t realize is that the body does not natural have allergies. In other words, nobody is born with an allergy. Instead, everyone who suffers from allergies developed these when their immune systems came into contact with the allergen.

In some individuals, the body’s immune system initiates a pro-inflammatory response as a result of the threat of the allergen. This is known as a type 2 immune response and is caused by allergic sensitization.

Allergies can manifest several different ways, and our bodies can react by developing allergic symptoms such as eczema, fever or anaphylaxis – some of these could lead to a severe and potentially deathly allergic reaction.
