How do allergies catch Children?

Allergies are immune system problems. Most allergic reactions occur when the immune system responds to “false alarms.” Normally, the human body protects itself from harmful agents such as viruses and bacteria. But defences can sometimes hit things that are mostly benign, like dust, mould, and pollen. In This Blog, We will discuss the Top Child Allergies that are most common.


Allergic reactions can occur anywhere in the body. This includes the eyes, stomach, skin lining, lungs, throat, sinuses, and nose. These are the places where immune system cells fight germs that are inhaled, ingested, or come into contact with the skin. Allergic reactions can cause:


  •     Nasal congestion, sneezing, itching, runny nose, ear, and palate itching.            
  •     Red, itchy, watery eyes.
  •     Redness, itching, dry skin.
  •     Hives or itching.
  •     Itchy rash.


Allergens are usually harmless. However, when a person has allergies, the body perceives these allergens as harmful. The body then attacks the allergen with an antibody called immunoglobulin E (IgE). These antibodies bind to specialized cells called mast cells. Allergens bind to antibodies. This causes the mast cells to release histamine and other chemicals that cause allergic reactions. When chemicals irritate the tissues surrounding the nose, they cause nasal allergy symptoms. When this happens in the airways of the lungs, it can cause asthma symptoms such as coughing and wheezing. If the reaction is systemic, it may be a severe allergic reaction.

What causes children’s allergies?

Many things can cause allergic reactions. Some common triggers for allergies are:

  •     Pollen from trees, grasses, and Weeds.
  •     Natural rubber latex.
  •     Animal dander, urine, sebum.

Which children are prone to allergies?

Allergies can happen to anyone. Age, gender, race, and social status are not important. Allergies are common in children. But allergies can occur at any age. And it can relapse after years of recovery. 

Allergies usually run in families. However, the exact reason is still unclear. Allergy symptoms often develop slowly over time.


What is a food allergy?

A food allergy is an immune system reaction that occurs immediately after eating certain foods. Even a small amount of the food you are allergic to can cause signs and symptoms such as digestive problems, hives, and airway swelling. It can cause or even cause a life-threatening reaction known as anaphylaxis.

Food allergies affect about 8% of children under the age of 5 and up to 4% of adults. There is no cure, but some children get better with food allergies as they get older.

How is allergy diagnosed in children?

To diagnose allergies, your healthcare provider will take a complete medical history and examine your child’s allergy. Providers may also test for:

Apply a small amount of the diluted allergen to the skin. Getting stabbed or injured. If a person is allergic to an allergen, small raised bumps (like mosquito bites) will appear after about 15 minutes. Several allergen tests can be performed simultaneously.


  • Blood test: Allergy blood tests measure IgE antibodies to specific allergens in the blood. The most widely used test is called RAST (radio allergy absorbance test). If a skin test is not possible, a blood test may be done. For example, people with certain skin diseases. or someone who has recently had a severe allergic reaction.


  • The challenge test: It is performed under the supervision of an allergist. Very small amounts of allergens are given to children by mouth. Only a challenge test can determine the severity of the allergy. A skin reaction or blood test only indicates the possibility of some reaction, not what the reaction is.
