Pediatric Allergy

The immune system of a youngster with an allergy will react negatively to the presence of the allergen because it will think it is harmful to the body. The body overreacts to the material, attempting to eliminate it as if it were a foreign intruder. Immunoglobulin E antibodies serve as the first line of defense against harmful invaders (IgE). In response to the allergen "invader," they trigger the release of chemicals (including histamine) into the bloodstream from particular cells.

These chemical processes are triggered by their release. The digestive system, respiratory system, skin, and eyes might all react negatively. This reaction will be triggered again if the allergen is reintroduced into the body.

What Are Pediatric Allergies?

Allergies occur when the immune system reacts abnormally to substances that are otherwise safe for most individuals but cause reactions in those who are allergic. This results in symptoms that can be anything from mildly bothersome to potentially fatal. Some people are allergic to medications, while others have problems with dust, pollen, and certain foods.

Allergies are common among both adults and children.

How do Pediatric allergies occur?

If an allergic youngster is exposed to an allergen, his or her immune system will react as if the substance were harmful. As a result, it overreacts, viewing the chemical as an enemy invader and attempting to eliminate it. Proteins termed immunoglobulin E are produced by the immune system to ward off harmful invaders (IgE). Certain cells respond to allergens by releasing substances (such as histamine) into the bloodstream as a form of defence against the allergen "invader."

Allergies are brought on by the chemical release itself. Negative reactions can manifest in a variety of ways, including on the skin, the lungs, the digestive system, the eyes, the nose, and the throat. This allergic reaction will be triggered again if the allergen is re-exposed in the future.

Kinds of Pediatric Allergies

Some typical allergies include:

  • Airborne Allergens include dust mites, pollen (the cause of hay fever), molds, animals, insects, and cockroaches.
  • Food Allergies such as cow's milk, eggs, fish, Honey, Wheat, Sesame or Shellfish
  • Antibiotics and several OTC medications contain compounds that might trigger an allergic reaction in those who are sensitive to insect venom, making these an additional common allergen. Itchy welts may appear on the skin after using certain cosmetics or laundry detergents. This usually occurs when an individual is sensitive to one or more of the items' substances. Some people are also sensitive to common substances like dyes, cleansers, and pesticides.

How do kids get these Allergies?

Allergic reactions are sometimes inherited from one's parents. However, this does not necessarily guarantee that a child will develop the same allergies if either of their parents does. In addition, an individual typically does not inherit an allergy to a specific substance but rather the propensity to develop allergies. Sometimes a child will develop allergies even though no one in their immediate family has ever suffered from them. Young people who are allergic to one thing are more likely to be allergic to other things.

Some children also experience cross-reactions. A protein in apples is identical to one in birch pollen, thus children who are allergic to birch pollen may have symptoms if they consume apples. For some reason, those who are allergic to latex (which can be found in latex gloves and other medical supplies) are also more prone to have reactions to kiwis, chestnuts, avocados, and bananas.


If your child has some cough or other cold-like symptoms that may last longer than a week or two or develops a "cold" at the same time every year, talk with your doctor, who might diagnose an allergy and prescribe medicines, or may refer you to an allergist (a doctor who specialises in allergies) for allergy tests.


Allergy susceptibility is often inherited, meaning that it can be handed down from parents to offspring through their DNA. However, this does not mean that if one parent has allergies, their offspring will necessarily develop them as well. As well, it's not the actual allergy that's inherited, but rather the susceptibility to developing allergies. Some children suffer from allergies even if no one in their immediate family shares the condition. Many times, a child who is allergic to one substance is also allergic to others.

There are also cross-reactions in certain young people. For instance, if a child is allergic to birch pollen, eating an apple could trigger their symptoms since apples contain a protein that is identical to the one found in birch pollen. In addition, for reasons that aren't entirely understood, those who are allergic to latex (which can be found in latex gloves and other forms of medical equipment) are also more likely to have an allergy to kiwi, chestnuts, avocados, and bananas.
