Allergies (Child) - Symptoms

Most allergic reactions are easily controlled. But some can lead to an anaphylactic reaction, which is a serious allergic reaction that progresses rapidly and can be fatal. Symptoms may include a combination of rashes, shortness of breath, chest pain or tightness, weak pulse, dizziness, swelling of the eyes, lips or tongue, difficulty swallowing, abdominal cramps or vomiting. An anaphylactic reaction is an emergency, which needs immediate medical attention.

Listed below are some common allergies, their symptoms and triggers. Consult your doctor if your child displays any of these symptoms.


Children with asthma often have cough, tight chest or difficulty breathing. These signs are worse in the morning or at night and could also be due to exercise or physical activity.

Common triggers include viral infections, cigarette smoke, house dust mites, animal fur, weather changes and even stress.

Allergic Rhinitis

Allergic rhinitis is usually due to inhaling house dust mites, mould and animal dander. The condition can be frustrating to a child as he or she will sneeze often and have an itchy and runny nose, which can get stuffy. The child may start to breathe through the mouth. Often the child also has watery and itchy eyes, which may become red and swollen.


In infants, eczema tends to occur on the cheeks, behind the ears and on the thighs. As the child grows, these dry, itchy and red patches are often found in the folds of the neck, arms and legs. Eczema can be worsened by food allergies or contact with allergens such as house dust mites and animal fur.

Food allergies

These can be mild or serious enough to cause an anaphylactic reaction. Common triggers include peanuts, eggs, wheat, soy and shellfish.


Hives are commonly caused by food allergies, medicines and viral infections. These raised, red and itchy skin patches look like mosquito bites and can be found on different parts of the body. They usually appear in crops and do not stay at the same spot for more than a few hours.

Contact dermatitis

Unlike hives, the red itchy patches are confined to areas which have come into direct contact with the allergen, which may include chemicals found in perfumes, cosmetics, detergents or plant substances such as poison ivy. If severe, the rashes may even blister.
