Who is affected by Allergies?

Allergies can affect anyone, at any age. You might have them as a child or only develop signs as an adult.  

Why does it only affect some people?

Your genetics make the most difference. Allergies were transferred on over the generations. If your parents have allergies, you are likely to have them as well. Your chances increase if one of your parents is allergic. If both parents are affected, the odds increase by more than double. There’s a risk you’ll have them even though no parent is allergic. 

You may inherit the tendency to develop allergies from your parents, but you may never experience symptoms. Or you might have allergies that aren’t the same as your parents’.

The environment around you has an effect as well. Before you experience an allergy, you must have a predisposition and be subjected to an allergen. The more intense the exposure, the more often you come into contact with the allergen, and the sooner you come into contact with the allergen, the more probable you are to be allergic.

Smoking, noise, infection, and hormones are also potential sources of allergies.
