Allergies in children are a common occurrence. The most common trigger that causes allergies are pollens, dust particles, certain food items, medicines etc. An allergy can be defined as the immune system’s reaction to an unknown or foreign substance. Usually, allergies can be treated with the help of medication and simple home remedies. However, in some severe cases, they might also turn out to be life-threatening. It has been stated that allergies are one of the most common reasons for children missing school (1). Read on to know more about allergies, causes, triggers, treatment options, and prevention techniques.
Types Of Allergies In Children
Allergies can be classified based on the part of the body affected and the mode of transmission of the allergen. Some major types of allergy that affect children are:
According to a 2021 survey by the CDC National Center for Health Statistics, about 27.2% of children experienced one or more allergy conditions, including seasonal allergies, eczema, and food allergies. Seasonal allergies were common, affecting 18.9% of children, while eczema affected 10.8% of children, and food allergies were identified in 5.8% of children.
We will tell you about each type of allergy, its causes, symptoms, and natural remedies.
Seasonal or Respiratory Allergies
Seasonal allergies may occur at any time of the year. They strike when the child gets exposed to environmental allergens including pollen, dust, smoke etc. These can affect around 40% of children (2).
Causes of seasonal allergies
The causes could vary from one child to another. Some of the basic ones are:
- Pollen from grass and trees and exposure to pesticides and fertilizers could be the causes for seasonal allergies in spring (3).
- Ragweed and grass are the primary triggers in summer for allergies (4).
- Pigweed, cocklebur, burning bush, tumbleweed, and lamb’s-quarters may lead to fall allergies (4).
- During colder days of winter, children are mostly indoors. Dust, latex in clothing, and mold are the common triggers for seasonal winter allergies (5).
- Hay feveriXAn allergic reaction to allergens such as pollen, pet hair, mold, and dust mites. is a common trigger for seasonal allergy. It could occur in any season. The pollen could be from weeds, grasses, and trees (6).
- Dust in the atmosphere, such as dust blowing in the sports field, smoke, or pollution smoke from vehicles.
- Dust in carpets, curtains, bedding, comforters.
- Animal fur, bird feathers and stuffed toys with fur. This is specially common in children playing with cats, dogs etc.
- Sometimes, allergic reaction occurs after the use of perfume, talcum powder, burning perfumed incense.
- Insect stings or bites can cause a severe allergic reaction.
Symptoms of seasonal allergies
The following are some of the common symptoms of seasonal allergies:

Skin Allergies in Children
Causes of skin allergies
Various substances and compounds could trigger an allergic reaction of the skin.
- Preservatives: Some children may suffer from allergies when their skin gets exposed to certain ingredients. Some common allergens include formaldehyde and methylisothiazolinone releasers such as DMDM hydantoin, diazolidinyl urea, and 3-diol bronopol. These could be found in moisturizers, facial cosmetics, shampoos, and other cosmetic products.
- Metals: According to the American Academy of Dermatology, approximately 11 million kids suffer from nickel allergy. This metal is usually found in jewelry, hooks, zippers, and in some straps too. Even face paints contain small amounts of these metals.
- Botanical allergens: Some children may have skin sensitivity. Contact with certain essential oils such as tea tree, lavender, peppermint, close, and citronella may cause skin reactions.
- If the child accidently touches an irritating chemical.

- Wearing cotton fabric may avoid itchiness in the case of skin allergies. Also, bathing in lukewarm water may help.
- Doctors may prescribe antihistamines to some children based on the symptoms.
- In some cases, doctors may suggest applying calcineurin inhibitorsiXMedicines that inhibit the production of calcineurin, an enzyme that is responsible for inflammation. or corticosteroid (topical steroid) to reduce inflammation.
- Moisturizers such as Vanicream and petroleum jelly may help in reducing irritation.
Food Allergies in Children
According to the Food Allergy Research & Education, one in 13 children in the US has a food allergy (14). When the child’s body reacts specifically to certain foods, it is called food allergy. It happens when the immune system confuses food compounds to be pathogensiXA disease-causing microorganism. and mounts an immune response. These responses are mostly initiated by immunoglobulin E (IgE) antibody. Food allergies could range from mild to severe (life-threatening).
Causes of food allergies
Each child can be allergic to different food, but some foods cause allergies more commonly than others (15).
- Milk, eggs, soy, wheat, and tree nuts may cause mild allergy symptoms.
- Peanuts, shellfish, and fish may cause severe symptoms in some children.
- Cow milk allergy.
- Gluten allergy.
Symptoms of food allergies
The symptoms of food hypersensitivity may start within a few minutes or hours after eating the food. Mild symptoms could affect the nose, mouth, gut, or skin. Severe symptoms could affect the throat, lung, mouth, gut, skin, heart, or other organs (15).
- Nausea, vomiting, cramps, and discomfort
- Vomiting and diarrhea
- Swelling and itchiness in the mouth, on the tongue, near lips, or in the throat
- Wheezing or difficulty in breathing
- Coughing or runny nose.
- EczemaiXA skin condition characterized by dry, itchy, and inflamed skin. or hives
Natural relief from food allergies
- There is no medication to treat food allergies. The only option is to avoid the allergen completely. If the food is a significant source of nutrition, then the child’s doctor may suggest supplements and alternative foods.
- Anti-histamines need to be given.
Other Allergies in Children
1. Pet allergy
Pet dander (such as fur, feathers, or flakes of skin), urine, and saliva could be potential allergens (16). The symptoms of pet allergy may include a skin rash, runny nose or sneezing, coughing, difficulty in breathing, and itchy or red eyes.
The treatment varies based on the severity of the symptoms. The mild ones may go away by washing hands with soap and water. Vacuuming and keeping the house clean can help get rid of the pet dander. However, the severe symptoms may be treated by allergy shots (prescribed by a doctor). The child should preferably avoid the pet to prevent allergies in the long run.
2. Medicine allergy
Certain medications could cause mild to severe allergic reactions in children. The symptoms may include pimples or redness from different kinds of steroids, purple or red rashes from antibiotics (that have phenolphthalein, tetracycline, or sulfa), purple area due to certain blood-thinners, and blisters due to sulfa, penicillin, or some antibiotics (17). Allergic reactions are very common with antibiotics mainly penicillin groups. Always note what drugs your child is allergic too and avoid it next time.
Based on the severity of the symptom, drug allergies in children may be treated with epinephrine, antihistamines, or corticosteroids as prescribed by the doctor. If the medication is temporary, then the symptoms go away on suspending the dosage. Parents can also discuss with their child’s doctor about alternative medicines that are unlikely to trigger an allergy.
When To Call A Doctor?
It is good to see a doctor if your child shows severe symptoms of an allergy. Also, if natural allergy remedies do not provide relief, then consult a doctor for appropriate treatment.
Frequently Asked Questions
1. What is the difference between food allergy and food intolerance in kids?
Food allergy is an immune system reaction where the body reacts to certain food. In contrast, food intolerance is a digestive system issue where the body is unable to digest a particular food. Generally, food allergy affects all body systems, causing mild to moderate symptoms. However, food intolerance only affects the digestive system and its symptoms are rarely adverse (15).
2. Which children are at risk for allergies?
Allergies can affect children of any age, race, gender, or socio-economic status (21). In fact, allergies are common in children and can happen at any age.
3. How common are allergies in children?
According to the American Academy of Allergy Asthma & Immunology (AAAI), “Worldwide, sensitization rates to one or more common allergens among school children are currently approaching 40 to 50% (22).”
Allergies in children can occur due to triggers such as dust, pollen, or a particular food. Most allergic reactions are manageable and seldom a cause for concern. However, severe allergic reactions such as anaphylaxis can occur in some cases, warranting immediate medical attention. Usually, allergies are hereditary though they can also be sporadic. The allergy treatment depends on the type and intensity of the reaction. Applying an ice pack on itchy skin, wearing cotton fabric, and bathing with lukewarm water may offer some relief. Keeping your child away from known allergens is the best way to avoid allergies in children.
