How Allergies Effect Children

An allergic reaction is the body's immune system response to certain elements in the environment. Children with allergies tend to react to certain substances that may not cause reactions to other children.

According to the Asthma and Allergy Foundation, approximately 20 percent of Americans, one in every five adults and children, have allergies which includes allergic asthma. About 80 percent of children with asthma have allergies and food allergies occur in 8 percent of children younger than age six.

Children are usually more vulnerable to allergies than adults. Food, dust mites, animal dander and pollen are the most common childhood allergies. These substances can cause the child to have rhinitis, asthma and eczema.Genetics and Allergies

A child has a 75 percent chance of having allergies if both parents have allergies and only a 50 percent chance if only one parent suffers from allergies.

Allergy Symptoms

When the body releases special antibodies called immunoglobin E, symptoms of an allergic reaction occur. These antibodies trigger the release of chemicals hat can cause the physical symptoms and changes associated with allergies. These include:

Hives
Runny nose
Itching or swelling of the lips, tongue or throat
Upset stomach, cramps, bloating or diarrhea
Wheezing or difficulty breathing
Anaphylactic shock - a life threatening body reaction which requires emergency care

If you believe that you or your child is suffering from allergies your doctor can do an allergy test to find out what is causing the allergic reaction.



Skin prick tests are the most common form done to test for allergies. The doctor will introduce small amounts of allergy triggers through the skin of the arm or back by pricking or puncturing the skin wiht a needle or similar device. If the patient is allergic to a substance a raised red itchy bump will appear. These reactions usually appear within 15 minutes. The size of the bump is important. The bigger it is the more sensitive the patient is to that particular substance. Your doctor may advise that you discontinue certain medications, especially antihistamines for several days prior to testing.

Your doctor, or allergist may choose to perform a blood test to check for allergies. This is usually performed if the patient has a skin rash which will make it difficult to see the reaction to the skin prick.

Treatment Options for Allergies

The most common form of treatment for allergies are over the counter and prescription drugs. Antihistamines are a broad class of drugs that block the inflammatory effects of histamine. These drugs prevent histamine from interacting with the cells which causes inflammation. Common over the counter antihistamines include: Benadryl and Chlor-Trimeton. Although, these may cause drowsiness.

Other alternatives which may not cause drowsiness are also available over the counter and by prescription. These include, Allegra, Claritin, Alavert and Zyrtec. You can also get these antihitamines with an added decongestant. Do not combine these medications or mix with alcohol. Also avoid opperating heavy machinery while taking these medications.
