An allergy is an immune system's reaction in response to certain foreign bodies. Some of these foreign bodies may not cause any harm in people who are non-allergic. Being foreign in nature, the immune system in the people allergic to that substance gets alerted and initiates a protective mechanism. It was Clemens Pirquet, an Austrian pediatrician, who used the word - allergy. It has been studied that more than 50 million Americans are diagnosed with some kind of an allergy.

What are the different types of allergy?

Not all people are allergic. Majority of the people would be allergic to only some kind of allergens while some people may be allergic to multiple allergens.

1. Food Allergy

Food allergy is mostly seen in infants and children, although it can affect people at any age. It usually occurs when the immune system reacts to a particular food as being hazardous. Almost all kinds of foods may initiate an allergy. Some people may show signs of severe allergy to foods including peas, beans, walnuts peanuts, lobster, crabs and shellfish.



2. Pet Allergy

Pets are a part of many families for long time now. However, some people may develop a pet allergy. These people should consider their options before deciding on which animal to keep as a pet. Allergens such as pet dander can be a problem for people with asthma. The pet hair is not an allergen in itself, but the molds, dust and other allergic substances that stick to the hair may cause allergies.

3. Rhinitis

Rhinitis or hay fever is a common type of allergy. A person suffering from allergic rhinitis may have a disrupted routine. Nasal inflammation or irritation may be a common symptom. This may also result in runny nose and sneezing. The nasal congestion may switch sides in cycles for several hours together.

4. Skin Allergy

Skin allergies are common and complicated as the exact source of allergy may not be found in certain cases. It can occur due to certain medications, foods or plants among the different kinds of rashes on the skin, hives and allergic eczema are commonly seen.

5. Drug Allergy

Depending upon the health, people may be allergic to variety of medicinal drugs. A hypersensitivity reaction occurs when the immune system reacts to the drugs. People experience variety of allergic side effects, some of which can even be fatal. For people with a family history of drug allergy, the probability goes higher.
Apart from these allergies, there may be various other allergies seen. Some of them can go away without a treatment. For others which prevail and cause problems, various treatments including auto injectors such as Epipen may be taken. Always consult your prescribing doctor before taking any medication as the drugs may not suit everyone. by Dorthy Ross
