The torment of seasonal alergies in children

Posted on May 13, 2010May 12, 2010 by News Health

About Seasonal Allergies

“Ah-choo!” It’s the third time this morning that your son has had a sneezing fit, and as you hand him another tissue you wonder if these cold-like symptoms — the sneezing, the congestion, and runny nose — have anything to do with the recent weather change. Well, if he gets similar symptoms at the same time every year, chances are you’re right: He’s probably got seasonal allergies.

Seasonal allergies, sometimes called “hay fever” or seasonal allergic rhinitis, are allergy symptoms that occur during certain times of the year, usually when outdoor molds release their spores or trees, grasses, and weeds release tiny pollen particles into the air to fertilize other plants.

The immune systems of people who are allergic to mold spores or pollen treat these particles (called allergens) as invaders and release chemicals, including histamine, into the bloodstream to defend against them. It’s the release of these chemicals that causes allergy symptoms.

People can be allergic to one or more types of pollen or mold. The type someone is allergic to determines when symptoms will occur. For example, in the mid-Atlantic states, tree pollination begins in February and lasts through May, grass from May through June, and weeds from August through October — thus, kids with these allergies are likely to have increased symptoms during those times of the year. Mold spores tend to peak midsummer through the fall, depending on location.

If your child has never had seasonal allergies in years past, it’s possible that they’re just beginning. Seasonal allergies can start at almost any time, but they usually develop by 10 years of age and reach their peak in the early twenties, with symptoms often disappearing later in adulthood.

Signs and Symptoms

If your child develops a “cold” at the same time every year, seasonal allergies might be to blame. Allergy symptoms, which usually come on suddenly and last as long as a person is exposed to a particular allergen, can include:

  • sneezing
  • itchy nose and/or throat
  • nasal congestion
  • clear, runny nose
  • coughing

These symptoms are often accompanied by itchy, watery, and/or red eyes, which is called allergic conjunctivitis. If your child develops wheezing and shortness of breath in addition to these symptoms, the allergy may have progressed into asthma.

Diagnosis

Seasonal allergies are fairly easy to identify because the pattern of symptoms returns from year to year following exposure to an allergen.

Talk with your doctor if you think your child might have allergies. The doctor will ask about symptoms and when they appear and, based on the answers and a physical exam, should be able to make a diagnosis. If not, the doctor may refer you to an allergist for blood or allergy skin tests.

To determine an allergy’s cause, allergists usually do skin tests in one of two ways:

  1. A drop of a purified liquid form of the allergen is dropped onto the skin and the area is pricked with a small pricking device.
  2. A small amount of allergen is injected just under the skin. This test stings a little but isn’t extremely painful. After about 15 minutes, if a lump surrounded by a reddish area appears (like a mosquito bite) at the injection site, the test is positive.

Even if a skin test or a blood test shows an allergy, a child must also have symptoms to be definitively diagnosed with an allergy. For example, a child who has a positive test for grass pollen and sneezes frequently while playing in the grass would be considered allergic to grass pollen.

Treatment

There is no real cure for seasonal allergies, but it is possible to relieve symptoms. Start by reducing or eliminating exposure to allergens. During allergy season, keep windows closed, use air conditioning if possible, and stay indoors when pollen counts are high.

Have your child wash hands or shower and change clothing after playing outside.  And don’t allow a child with seasonal allergies to mow the lawn (this tends to kick up pollen and mold spores).

If reducing exposure isn’t possible or is ineffective, medicines can help ease allergy symptoms. They may include decongestants, antihistamines, and nasal spray steroids. If symptoms cannot be managed with medicines, the doctor may recommend taking your child to an allergist or immunologist for regular allergy shots (immunotherapy), which can help desensitize kids to allergens.
