Do you know the truth about your allergies?

Types Of Allergies
Bee Stings And Insect Bites

About 100 people a year die from allergic reactions to bee stings. Fire-ant bites also can be life threatening.

Cockroach Allergies

This lowly insect is high on the list of troublesome allergens -- especially among city dwellers with asthma.

Contact Allergies

Every year, approximately 70 percent of Americans are affected by skin allergies -- the most common allergens being poison ivy, oak and sumac.

Medication Allergies

Anywhere between 3 percent and 35 percent of Americans experience an allergic reaction to some type of drug.

Dust Mite Allergies

These little bugs are so small that between 100 and 500 individual mites live on a single gram of dust. Despite their size, dust mites cause some big problems. Or more specifically, their feces do.

Hay Fever

Hay fever is the most common allergy, affecting at least 10 percent of all Americans and half of those with allergies. It's caused by unseen pollen particles in the air -- from trees, weeds and grasses.

Mold Allergies

After pollens, molds are the leading cause of outdoor airborne allergies. Mold forms on fallen leaves, soil, debris and other moist surfaces.

Pet Allergies

Man's best friend can be anything but that to those with pet allergies. Here, the big problem is a protein in the skin and saliva of cats and dogs -- not their hair, as is widely believed.

Poison Ivy

The wicked itch and bothersome rash are the result of urushiol oil, a potent toxin. Get as little as one-billionth of a gram on your skin and you might be scratching yourself silly.

Skin and Chemical Allergies

Allergic reactions can develop simply by touching substance to which you have been sensitized.

Food Allergies

At least 40 percent of Americans think they are allergic to some foods. In reality, only about 5 percent really are, including only 1 to 2 percent of adults.

Seasonal Allergies

An estimated 40 million Americans suffer from allergies. Between the runny nose, itchy, watery eyes, sneezing, skin rashes and breathing difficulties, allergies can be mildly irritating or make you downright miserable.

Latex Allergies

Like any other type of allergy, latex allergies arise when the immune system, which normally works to guard the body against foreign invaders that threaten its integrity or health, reacts to an otherwise harmless substance.

Children And Allergies
Penicillin Allergy In Children
Children with allergies are more likely to have severe reactions to penicillin than children who don't have allergies.
Latex Allergy In Children
Some children exhibit a hypersensitivity to latex, the natural rubber found in rubber gloves, balloons, baby-bottle nipples, toys and pacifiers.
Insect Stings In Children
Your child is stung by a honeybee. Is this a medical emergency? In most cases, it is not.
Airborne Allergies In Children
Grasses, trees and weeds aren't the only things that release allergens into the air. Other airborne allergens come from pets, molds, dust mites and cockroaches.
