Allergies and the immune system

Your child’s immune system is one of the primary barriers between him and the illnesses of the world. It works by attacking substances that enter the body that are dangerous to your child’s health. But, sometimes the immune system goes haywire and attacks completely harmless substances. This is what causes allergies.

While most kids can easily tolerate pet hair, food proteins, and pollen, kids who have a misguided immune system suffer a range of symptoms that can make them not only miserable, but downright sick. Some immune system reactions can even be life-threatening for your child.
