How Allergies Affect Children: A Pediatrician’s View

For many children, a simple day outdoors or a glass of milk can lead to sniffles, stomach aches, or itchy eyes. Allergies are one of the most common chronic conditions in children—and while they’re rarely life-threatening, they can make daily life more challenging for both kids and parents.

At Pediatrics Unlimited, LLC in Oak Park, IL, Dr. Jeffrey A. Cabotaje and Dr. Elizabeth Wollensak help families recognize and manage the wide range of allergy symptoms in children. Understanding how allergies affect the body is the first step toward helping your child feel better and breathe easier.

What Causes Allergies In Children

Allergies occur when a child’s immune system overreacts to something that’s normally harmless, such as pollen, dust mites, pet dander, certain foods, or insect stings. The body treats the substance—called an allergen—as a threat, triggering an immune response that causes symptoms.

Some children are genetically more likely to develop allergies, especially if one or both parents have a history of allergic conditions like asthma, eczema, or hay fever.

Common Allergy Symptoms In Kids

Allergy symptoms vary depending on the trigger and can show up in different parts of the body. Some of the most common include:

• Sneezing, nasal congestion, and runny nose
• Itchy, watery, or red eyes
• Skin rashes like hives or eczema
• Upset stomach, nausea, or diarrhea (often with food allergies)
• Persistent cough, wheezing, or shortness of breath

In more serious cases, an allergic reaction can cause anaphylaxis—a rapid, severe response that requires emergency care.

Seasonal Vs. Year-Round Allergies

Seasonal allergies are often caused by tree, grass, or weed pollen and flare up in the spring, summer, or fall. Children may seem fine during part of the year, then start sneezing and itching when pollen counts rise.

Year-round allergies, or perennial allergies, are typically triggered by indoor substances like dust mites, mold, or pet dander. These symptoms tend to persist regardless of the season.

How Pediatricians Diagnose Allergies

Diagnosing allergies often begins with a conversation. A pediatrician will ask about your child’s symptoms, health history, and possible triggers. Depending on the case, they may recommend:

• Allergy testing (skin or blood tests)
• A trial period of avoiding suspected allergens
• Referrals to an allergy specialist for further evaluation

Managing Allergies Effectively

Once your child’s allergies are identified, the goal is to reduce exposure and control symptoms. Treatment may include:

• Over-the-counter or prescription medications (such as antihistamines or nasal sprays)
• Allergen avoidance strategies, like keeping windows closed during high pollen days
• Special diets or epinephrine auto-injectors for food allergies

In many cases, symptoms can be managed well with guidance from your child’s pediatrician.
