Allergies can be defined as malfunctions in the immune system. When the immune system struggles against a particular substance, it can have an unpleasant reaction when it is exposed to it. Contact can come about because of a number of reasons, particles of allergy-inducing substances can be found in the air and the environment, or can be contained in certain foods. These reactions can be sudden, and result in a great deal of irritation, and at times, a great deal of risk.

Certain alternative consequences, however, can be a little more serious. Sometimes, they can even endanger a sufferer’s life. This risk usually comes from asthma victims, or people who are allergic to specific medicines or food, like nuts or penicillin. Poisonous insects may also pose a serious threat, such as bees, whose sting can be lethal in some people.
