Yes. Yes, we do see allergies in families. Your risk of allergies increases if one parent has allergies, and is even higher if both parents suffer from allergies. Interestingly, we are seeing that exposure to allergens may also play a part in the development of allergies in children. Rural areas, with high levels of plant and animal allergens, actually have lower levels of allergic disease in kids.
Yes but. The ability to be allergic can be inherited but is very complex. One can also see allergic kids in families that have no allergies. There is a complex relationship between the ability to be allergic and the environment in which we live and this will influence how allergy may be manifested.
