An estimated 50 million people in the United States experience some type of allergy, most of which rear their ugly heads during early childhood, according to the American College of Allergy, Asthma & Immunology (ACAAI). In fact, your child is more likely to experience an allergy than any other chronic illness.
Types of allergies and their symptoms
Dust and pollen allergies are both common and may result in a runny or itchy nose, sneezing, stuffiness and watery eyes. You may suspect that your child has a dust allergy is if he or she experiences these symptoms when you dust, sweep or vacuum. Interestingly, it may not be the dust that causes the reaction, but tiny, eight-legged dust mites, which have certain proteins in their bodies and feces to which humans are sensitive.
Hay fever, also known as allergic rhinitis, is a reaction to mold spores and pollen from ragweed, grasses and trees. About 40 million Americans experience this allergy.
Pet allergies occur in about 10 percent of the population, according to the ACAAI. As Fido or Fluffy sheds its fur, your child may experience watery eyes, sneezing or swelling where they came into contact with the animal. Pet dander, skin flakes, saliva and urine can cause allergic reactions in people sensitive to these allergens. Your child's allergies may also flare in response to the pollen, mold spores and other outdoor allergens brought inside on your animal's fur.
Insect sting allergies can make an unwanted encounter with a bee very dangerous. If your child is stung and develops hives, itchiness, difficulty breathing, low blood pressure, dizziness, unconsciousness or swelling of the tongue or any other area other than the sting site, you should seek immediate medical attention.
Food allergies are relatively rare—the ACAAI estimates the prevalence to be around 4 percent—but can cause serious, life-threatening reactions. Sensitivity or intolerance to peanuts, tree nuts, shellfish or other foods may result in severe swelling of the throat, which requires immediate medical attention.
Some children also experience delayed contact allergies caused by touching a substance such as nickel, polishes, rugs, fabric softeners, deodorants, cosmetics, perfumes, preservatives and dyes. And don't forget plants like poison ivy, poison oak and sumac. These plants contain a compound that can cause severe skin reactions in people who are allergic—up to 85 percent of Americans. Such reactions occur two days after exposure and can persist for weeks without treatment.
What to do if an allergy is suspected
To reduce the chances of a serious reaction, it's important to receive prompt diagnosis of an allergy if one is suspected. An allergist is the best person for this job, and you can find a certified physician on the ACAAI website (www.acaai.org) or through the American Academy of Allergy, Asthma & Immunology (www.aaaai.org).
According to the Nemours Foundation, there are skin tests for allergies that tend to be pretty reliable in kids older than 2.
In one method, a physician drops a bit of the suspected allergen on your child's skin, and then gently pricks the area to see what reaction occurs. An allergist may also inject a small amount of the allergen under the skin— don't worry, it's not as painful as it sounds—and wait 15 minutes to see whether a bump appears. If a skin test doesn't yield results or if your child's reactions are especially severe, a blood test may be required.
If your child is diagnosed with an allergy
Your health care professional should give you instructions on helping your child avoid triggers, as well as how to treat reactions. If your child suffers any severe allergic reaction—such as anaphylactic shock or asthma that causes shortness of breath or difficulty breathing, or any other extreme discomfort—you should seek medical attention immediately.
Your health care professional may also prescribe medications, recommend over-the-counter remedies or suggest allergy shots or injections. Although there is no cure for allergies, treatments can provide varying degrees of relief from allergy symptoms.
Depending on your child's allergies, you can help him or her avoid the allergens that trigger symptoms. In cases of airborne allergens, such as dust and pollen, it helps to use an air conditioner inside your home and car. Special air-filtering devices can be added to your home's heating and cooling systems. In addition, portable air cleaning devices used in individual rooms can be helpful. Ask your health care professional which type would be best. Following are some helpful tips for avoiding exposure to various allergens.
Pollens
Unfortunately, short of staying indoors when pollen counts are high—and even that may not help—there's no easy way to evade all wind-borne pollen. Here are some things you can do:
Molds
Mold allergens, too, can be difficult to avoid. Here are some tips to reduce exposure:
Dust mites
Dust mites are most effectively reduced by decreasing the amount of dust in your home. You can:
