Allergies are your body’s response to environmental substances that are usually harmless to the majority of us examples are pollen, molds, animal dander, latex, certain foods, and insect stings. Allergy manifestations range from mild –skin rash or hives, itchiness, running watery nose, and watery/red eyes – to life-threatening reactions.
Allergies are your body’s response to a substance it views as a dangerous “invader.” For instance, coming into contact with what is generally a benign substance, such as pollen, may cause your immune system (your body’s, defense)to respond. Substances that lead to these reactions are called allergens.

Allergy-producing substances are called “allergens.” Illustrations of allergens include house dust mites, pollens, moulds, animal proteins,insect venom, foods, and also medicines. To know the language of allergy, it is important to understand that allergens are substances that are foreign to the body and can cause an allergic response in specific conditions.

An “allergic reaction” is the method by which your body responds to the allergen. A sequence of events occur that lead to an allergic reaction. If you are susceptible to allergies, the first time you’re exposed to a particular allergen (like pollen), your body reacts by producing allergic (IgE) antibodies. The function of these antibodies is to find the allergic insults and help remove them from your system. Resulting, a chemical called histamine is released and lead to manifestations of allergies.
