IMMUNOLOGY

Detailed explanation-1: -The environment also has a significant role in the development of allergies. In most cases, a child will develop an allergic condition when they have the genetic predisposition for it. So when a child is exposed to a specific allergen that they have a genetic predisposition for, it can worsen their allergic condition.

Detailed explanation-2: -Among the most extensively studied environmental factors influencing allergy are airborne allergens: dust mites, pollens, fungi and animal dander. Foods may elicit both true IgE-mediated allergy and also various non-immunological reactions, associated with direct release of mediators or toxic activity.

Detailed explanation-3: -Does someone in your family have allergies? If so, you might have allergies too. That’s because allergies are often hereditary. While allergies are more common in children, they can appear at any age.

Detailed explanation-4: -Food allergies may have a genetic component, but allergy susceptibility appears to be influenced by genetic predisposition and environmental factors. It is important to remember that allergies within families may also reflect shared environmental conditions that contribute to the development of food allergies.
