Allergy

An allergy is an inappropriate and sometimes life-threating immune response (reaction of the immune system).[1][2] The term allergy is also known as hypersensitivity. People who have allergies often are sensitive to more than one thing. Substances that often cause reactions can be grouped as

* Food (and proteins comprised in food) [1]
* Insect stings
* Medicines (or common components of medicines such as sulfites)
* Latex (used in medical supplies like gloves)
* Mold spores
* Pet dander
* Pollen
* Dust mites

## Causes[edit]

Allergists (scientist that study allergies) think both genetics and the environment contribute to the manifestation of allergies. Normally, your immune system fights  germs. It is the body's God-given defense system against potential harm. In most allergic reactions, however, the immune system is attacking a normally harmless substance.[2]

Some studies have shown a link between vaccinations and food allergies.[3][4]

## Symptoms[edit]

A severe allergic reaction such as swelling of the throat, lips and mouth and eventual obstruction of the trachea (called anaphylaxis) is life-threatening, immediate medical attention is required to save the victim's life.

Non-life threating allergic reaction symptoms can include: a runny nose, sneezing, itching, rashes, swelling of the skin, or asthma. Symptoms can vary. Allergies should not be confused with intolerances/food intolerances which are never life-threating. Although Food Intolerances (problems with digestion and metabolism of certain foods) can make one feel bad (by causing indigestion or bloating such as in a gluten intolerance), they are not fatal.[2]
