In this article we're going to discuss what causes allergies and why some people are more prone to suffer from allergies than others.

The first thing we need to understand is what an allergy is. An allergy is a reaction to something outside the body that the body itself feels is a threat to it. More specifically, this is the immune system.

The truth of the matter is, everybody has allergies in as much as the body is always going to view outside agents such as pollen, grass, weeds, and even foods as invaders.
