Protection from skin infection causing germs

An allergy is a hypersensitivity disorder of the immune system which results in the body’s negative reaction towards otherwise innocuous substances
An allergen is any substance that causes an abnormally vigorous immune response when it enters our body. The allergen cause the immune system to fights off a perceived threat that would otherwise be harmless to the body. An allergy is a hypersensitivity disorder of the immune system which results in the body’s negative reaction towards otherwise innocuous substances like food, common medicines, dust and pollen to name a few.
Allergic responses vary from individual to individual and can range from mildly discomforting to potentially fatal anaphylactic shocks.
Causes
There are thousands of allergens that can trigger allergies, but some of the most common include:
Pharmaceutical drugs such as antihistamines are particularly useful in combating allergic reactions caused by airborne allergens. Decongestants and nasal sprays are similarly effective against allergic reactions that attack the respiratory system
Certain foods, medicines and insect stings are known to trigger potentially fatal anaphylactic reactions. Administering adrenaline is the medically preferred course of action in such cases.
Allergies can potentially be passed down from generation to generation. However, the diagnoses of allergic reactions cannot be solely attributed to genetic factors and as such scientists are currently conducting extensive studies in environmental pollution and keeping a close eye on allergen levels in the air to isolate the root cause of allergic responses.
Not necessarily. Allergic responses may be similar but are essentially unique for every individual. Hay fever is a common allergy cause by pollen but while one person may be allergic to pollen in general, another may be allergic to pollen from a specific plant. It is crucial that one understands that not every reaction and intolerance exhibited by our bodies is allergic in nature.
