Allergies in children occur when the body's immune system overreacts to harmless substances. These substances are called allergens , and allergic reactions can affect a child's quality of life.

Allergies are often linked to an innate predisposition , and genetic factors, combined with environmental factors, can cause allergies in children. Allergies, such as allergic asthma in children , can present with very different symptoms in various forms.

1. Causes of Allergies in Children

Allergies in children occur when the body's immune system overreacts to harmless substances. These substances are called allergens and can seriously affect a child's quality of life.

Allergies are generally linked to genetic predisposition and may develop in combination with environmental factors.

Main reasons:

• Genetic predisposition

• Environmental factors

• Food allergies

• Immune system disorders

• Drug allergies

• Insect stings and latex

• Latex allergies

Genetic Predisposition

Allergies are often linked to a family history of similar conditions. If one or both parents have allergies, a child may be more likely to develop them.

Environmental Factors

Environmental factors can trigger allergies. For example, factors such as pollen, dust mites, pet dander, fungi, cigarette smoke, and pollution can cause allergic reactions in children.

Food Allergies

Food allergies are a common problem in children, especially those aged 1–2 years .

Milk, eggs, nuts, fish, and seafood are the most common foods that can cause allergies. Food allergies can cause serious reactions such as nausea, vomiting, abdominal pain, rashes, and anaphylaxis .

Immune System Disorders

Allergic diseases are caused by the immune system mistakenly overreacting to harmless substances. These disorders can lead to allergic reactions in children.

Drug Allergies

Allergies can develop, particularly from antibiotics like penicillin . These allergies can even cause anaphylactic reactions and severely affect the respiratory system. Therefore, drug allergy prevention is crucial in children.

Insect Sting Allergies

With the sting of insects such as bees:

• Skin lesions

• Symptoms such as skin swelling and redness

• Even in severe allergic reactions, anaphylaxis may occur.

Latex Allergies

It is an allergy to materials containing latex , such as gloves and balloons . It manifests itself through lesions on the skin.

2. Symptoms of Allergies in Children

Allergies can manifest with a variety of symptoms in children. These symptoms may vary depending on the type of allergy.

Below you'll find common allergy symptoms in children. Symptoms can vary depending on the type of allergy.

• Skin reactions

• Respiratory problems

• Digestive problems

• Severe allergic reactions (anaphylaxis)

• Eye inflammations

Skin Reactions

Allergic reactions such as itching, rash, redness, or hives (urticaria) are common. Food allergies or insect bites, in particular, can cause these types of skin reactions.

Doctor visits due to skin allergies are quite common in children.

Respiratory Problems

Symptoms such as allergic rhinitis (hay fever), nasal congestion, runny nose, sneezing and itchy throat are common symptoms of allergic reactions in children.

It can also cause allergic asthma , cough, wheezing and shortness of breath in children.

Digestive Problems

Food allergies can cause digestive problems such as abdominal pain, vomiting, diarrhea, or constipation. They may need to be linked to a specific food the child ate.

Severe Allergic Reactions (Anaphylaxis)

Allergic reactions can sometimes develop into a serious condition called anaphylaxis .

This condition can make it difficult for the child to breathe and requires immediate medical attention.

Symptoms of anaphylaxis:

• Swelling (especially in the lips, tongue, or throat)

• Shortness of breath

• Hypotension

• Fainting

Eye Inflammation

Allergic conjunctivitis may present with symptoms such as watering, itching, redness and burning in the eyes.

Allergic conjunctivitis in children is often associated with exposure to allergens such as pollen or dust.

3. Allergy Diagnosis and Tests in Children

Allergy tests measure the immune system's response to an allergen.

Allergy testing in children can be performed in both public and private hospitals in Ankara and other cities.

Things to consider before the allergy test:
Antihistamine or cortisone use should be discontinued 7 days before the test.

Allergy Tests

• Blood test (IgE measurement)

• Skin prick test

• Patch test

• Intradermal skin test

IgE Measurement in Blood

Allergens are added to the child's blood sample, and IgE levels are measured. Positive test results indicate the substances to which the child is allergic.

Skin Prick Test

Light punctures are made on the forearm with a needle, allergens are applied to the skin, and reactions are observed.

Reactions such as redness and itching indicate that the body is reacting to that substance and is allergic.

Intradermal Skin Test

If the skin prick test is negative, this test is performed. A small amount of the allergen is injected into the epidermis using a syringe, and the skin's reaction is evaluated.

Patch Test

This test detects food allergies, substance allergies in contact dermatitis, and substances that cause allergies through skin contact.

Allergens are applied to the skin on the arm, covered with a bandage, and left for 48 hours . After 48 hours, the bandage is removed and skin reactions are observed.

Things to Consider Before an Allergy Test (Summary)

Allergy tests are performed to measure the immune system's response to an allergen. Based on this response, the allergen is identified.

However, medications used for allergies , such as antihistamines or cortisone, suppress this response.

For a healthy result, the use of these drugs should be stopped 7 days before the test .

4. Allergy Treatment and Management in Children

Treatment for allergies in children varies depending on the type and severity of the allergy. Treatment generally focuses on preventing allergic reactions , but in some cases, medication may be necessary.

Allergy treatment and management in children:

• Avoiding allergens

• Antihistamines

• Corticosteroids

• Allergy shots (immunotherapy)

• Emergency intervention (anaphylaxis)

✅ Avoiding Allergens

The most effective way to prevent allergic reactions is to avoid allergens .

It is important to determine what causes children's allergies in order to reduce their exposure to allergens.

For example, cleaning the home or using appropriate air filters can limit exposure to allergens such as pollen or dust mites.

✅ Antihistamines

Antihistamines , which are allergy medications for children , are medications commonly used to relieve allergic reactions.

These medications reduce allergic symptoms by blocking the body's production of histamine. They may be recommended for allergic rhinitis, skin rashes, or itchy eyes.

✅ Corticosteroids

In severe allergic reactions or severe conditions like asthma , doctors may recommend corticosteroid therapy. These medications help reduce inflammation and relax the airways.

✅ Allergy Vaccines (Immunotherapy)

Allergy vaccinations may be recommended for children, especially those who are sensitive to allergens such as pollen or house dust .

This treatment aims to train the immune system to resist allergens and can reduce allergic reactions in the long run.

✅ Emergency Response (Anaphylaxis)

In severe allergic reactions such as anaphylaxis, an immediate injection of epinephrine (adrenaline) may be required.

Depending on the child's condition, immediate admission to the hospital is essential.

5. Tips and Precautions for Allergies in Children

  to create the right treatment plan for allergies .

6. How Do Allergies Affect Growth and Development in Children?

Food allergies, in particular, can affect the absorption of nutrients by causing inflammation in the digestive system .

Since nutrients cannot be absorbed adequately, it can cause growth and developmental delays in children .

What Causes Allergies in Children?

• In children, allergies have a negative impact on growth and development . In children, allergies can cause growth retardation.

• Diseases like allergic rhinitis , which particularly affect the respiratory system, significantly impact a child's quality of life. Sleep is poor at night, and because the brain doesn't receive enough oxygen, its functions are affected.
  Concentration is impaired, and academic performance declines. This, in turn, leads to a lack of self-confidence in the child . This decreased cognitive function can lead to increased irritability and tension, potentially leading to depression.

• Infections caused by allergies increase; allergies pave the way for diseases such as sinusitis, allergic rhinitis, and otitis .

Allergies in children are a condition in which the body's immune system overreacts, resulting from genetic and environmental factors. Allergies can lead to various health problems, but they can be managed with appropriate treatment and allergen avoidance.

Parents should monitor their children's allergic reactions, apply the correct treatment methods and seek professional help when necessary.
