What are the causes of allergies? This online quiz challenges your knowledge of common food and household allergens, environmental triggers, allergic diseases and conditions, and allergy symptoms and treatments.
Allergy (Allergies)
An allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.

The dose is increased each time until a maintenance dose is reached. Side effects of allergy shots include itchy eyes, shortness of breath, runny nose, tight throat, redness, swelling, and irritation.

Avoidance of known allergens is the recommended treatment, but if this is not possible, antihistamines, decongestants, and nasal sprays may help alleviate symptoms.
How Long Does an Allergic Reaction Last?

Serious illness is more likely in elderly people and those with underlying medical conditions such as heart disease, diabetes, chronic respiratory disease, and cancer.
Sinus Infection vs. Allergies
Both sinus infections and allergies (allergic rhinitis) cause symptoms such as runny or stuffy nose and fatigue. Sinus infection (known as sinusitis) is inflammation of the sinuses, caused by infection from bacteria, viruses, and/or fungi (molds). Allergic rhinitis occurs when certain allergies cause nasal symptoms. When a person with allergies breathes in an allergen, such as pollen, dust, or animal dander, symptoms such as runny or stuffy nose, itching, sneezing, and fatigue occur.
Skin Test for Allergy
An allergy skin test helps identify triggers for one's allergic reactions. Small amounts of allergy-provoking substances (allergens) are scratched into the skin. Redness and swelling develop if one is allergic to the substance. A positive allergy skin test implies that the person has an IgE antibody response to that substance. The test is rapid, simple, and relatively safe.
What Are the 4 Types of Allergic Reactions?
Allergists recognize four types of allergic reactions: Type I or anaphylactic reactions, type II or cytotoxic reactions, type III or immunocomplex reactions and type IV or cell-mediated reactions.
