Detailed explanation-2: -An allergy is when your immune system reacts to something that is harmless to most people. Substances that cause allergies are called ‘allergens’. Common allergies include: food allergies (including fish and shellfish, nuts, eggs, wheat, dairy, soy)

Detailed explanation-3: -When a harmless substance such as dust, mold, or pollen is encountered by a person who is allergic to that substance, the immune system may over react by producing antibodies that “attack” the allergen. The can cause wheezing, itching, runny nose, watery or itchy eyes, and other symptoms.

Detailed explanation-4: -When you have allergies, your immune system makes antibodies that identify a particular allergen as harmful, even though it isn’t. When you come into contact with the allergen, your immune system’s reaction can inflame your skin, sinuses, airways or digestive system.

Detailed explanation-5: -Allergy occurs when a person reacts to substances in the environment that are harmless to most people. These substances are known as allergens and are found in dust mites, pets, pollen, insects, ticks, moulds, foods and some medications. Atopy is the genetic tendency to develop allergic diseases.
