Recognizing and Managing Pediatric Allergies: From Food to Environment

Your child keeps sneezing throughout the day. Or they break out in hives after eating certain foods. Or they are constantly rubbing their itchy eyes. Is it just a cold, or could it be allergies?

Allergies in children are on the rise. Between rising urban pollution, dust in homes, and changing food habits, more kids are dealing with allergy symptoms than ever before. Let's talk about what to look for and what you can do.

What Are Allergies?

An allergy happens when your child's immune system overreacts to something harmless, like pollen, dust, or milk. The body treats these substances as dangerous invaders and releases chemicals like histamine to fight them off. This causes allergy symptoms.

The most common types of allergies are food allergies, dust and environmental allergies, pollen allergies (especially during winter months), and pet allergies.

Allergy Symptoms in Children

Allergy symptoms in children vary depending on the triggers and the way the child is exposed.

Respiratory Symptoms

• Sneezing fits, especially in the morning.
• A runny or stuffy nose that lasts more than 2 weeks.
• Itchy nose (kids often rub their noses upwards with their palms).
• Coughing, especially at night.
• Wheezing or difficulty breathing.
• Throat clearing.

Eye Symptoms

• Red, itchy, watery eyes.
• Dark circles under eyes (allergic shiners).
• Rubbing eyes frequently.

Skin Symptoms

• Hives (raised, itchy bumps).
• Eczema (dry, itchy, red patches).
• Itching.
• Swelling of the face, lips, or tongue.

Stomach Symptoms (Usually Food Allergies)

• Vomiting.
• Diarrhoea.
• Stomach cramps.
• Nausea.

If your child has these symptoms lasting more than 1-2 weeks, especially if they follow a pattern or occur in certain situations, allergies might be the cause.

Food Allergies in Children

Food allergies are less common than environmental allergies, but can be more serious. About 6-8% of children have food allergies.

Common Food Allergens

The "Big Nine" allergens cause 90% of reactions:

• Milk (very common in toddlers)
• Eggs
• Peanuts
• Tree nuts (cashews, almonds, walnuts)
• Soy
• Wheat
• Fish
• Shellfish (prawns, crabs)
• Sesame

Signs of Food Allergies

Reactions can happen within minutes to hours after eating:

Mild to Moderate:

• Hives or rash
• Itching in the mouth or throat
• Runny nose
• Stomach pain
• Vomiting or diarrhoea

Severe (Anaphylaxis):

• Difficulty breathing
• Swelling of the throat or tongue
• Rapid pulse
• Dizziness or fainting
• Drop in blood pressure

Anaphylaxis is a medical emergency. If your child shows these signs, give adrenaline (if prescribed) and rush to the nearest hospital immediately.

Food Intolerance vs Food Allergy

Many parents confuse these. They are different:

Food Allergy: Immune system reaction. Even tiny amounts cause symptoms. It can be life-threatening.

Food Intolerance: Digestive system problem. Larger amounts are needed to cause symptoms. Uncomfortable but not dangerous.

Example: Lactose intolerance (inability to digest milk sugar) results in stomach upsets. Milk allergy (immunological reaction to milk proteins) may lead to hives, respiratory problems, or anaphylactic shock.

Environmental Allergies in Kids

Environmental allergies in kids are quite prevalent owing to rising levels of environmental pollution and dust.

Common Environmental Triggers

Dust Mites: Dust mites are tiny insects that live in mattresses, pillows, carpets, and stuffed toys.

Pollen: From trees, grasses, and weeds. High pollen concentrations are felt during the winter season.  

Mould: It grows in moist areas, such as bathrooms, kitchens, and affected walls during monsoons. It is experienced during and after the monsoon season.

Pet Dander: It is present in pet skin flakes, saliva, and urine. Children who have pets, such as dogs, cats, or birds, are at risk.

Cockroaches: Their droppings trigger allergies.

Pollution: Vehicle exhaust, industrial smoke, construction dust, especially bad in cities.

Dust Allergy in Children: Symptoms

Dust allergies are common in urban households and are worth every parent's attention. Symptoms of dust allergy in children are

• Sneezing fits when cleaning or sweeping.
• Stuffy or runny nose, worse in mornings (after sleeping in dusty bedding).
• Itchy, watery eyes.
• Coughing or wheezing.
• Breathing difficulty.
• Worsening at night or early morning.
• Getting better when away from home (staying with relatives).

Many homes have carpets, heavy curtains, and lots of soft furnishings that collect dust. This makes dust allergies worse.

Childhood Allergy Treatment

Childhood allergy treatment involves avoidance, medication, and, sometimes, immunotherapy.

Avoidance Strategies

For Dust Allergies:

• Use allergen-proof covers on mattresses and pillows.
• Wash bedding weekly in hot water.
• Reduce soft toys (or wash them weekly).
• Avoid heavy curtains; use washable blinds.
• Vacuum regularly (when the child isn't home).
• Keep humidity low (use dehumidifiers during the monsoon).
• Avoid carpets; prefer tiles or wood flooring.

For Food Allergies:

• Read labels carefully (food items often lack clear allergen warnings).
• Inform the school and caregivers.
• Teach older children to ask about ingredients.
• Carry safe snacks to parties and outings.
• Be cautious with street food.

For Pollen Allergies:

• Keep windows closed during high pollen seasons.
• Bathe children after outdoor play.
• Use air purifiers with HEPA filters.
• Limit outdoor activities on high-pollen days.

Immunotherapy (Allergy Shots)

For severe environmental allergies that are not controlled with medication, doctors might suggest immunotherapy. Small doses of the allergen are administered to help the body build tolerance.

When to See a Doctor

See a paediatrician or allergist if:

• The symptoms persist for more than 2 weeks.
• The allergy interferes with sleep, school, and daily activities.
• There is a suspected food allergy.
• If your child has had a severe reaction
• Asthma symptoms appear (wheezing, coughing).

Diagnosis

Several tests are done by doctors:

Skin Prick Test: A small amount of the allergen is applied to the skin to determine which allergens trigger a reaction. Fast and easy, and conducted in the doctor’s office.

Blood Tests: Antibodies to particular allergens are measured. Useful for children with skin conditions or those too young to undergo skin testing.

Food Challenge: Under medical supervision, the child eats a suspected allergen to confirm allergy. Only done in a hospital setting.

Elimination Diet: Avoid the suspected food for 2-4 weeks, then reintroduce it while observing for symptoms.

Conclusion

Allergies are common but manageable. Early recognition and proper treatment help children live normal, active lives. Symptoms can be identified, and a treatment plan can be developed with your doctor. With the proper strategy, your child can fully engage in school, sports, and social events.
