What types of allergies are common in children?

SKĐS - Allergies in children are a condition where the child's body overreacts to foreign allergens through the immune system. Allergic diseases are common in children who have family members with allergies.

Common allergies in children:

Food allergies

Food allergies are common in children, including both breastfed babies (milk allergy) and older children. Children can be allergic to almost any food, however common allergies include peanuts, nuts, fish, shrimp, eggs, soy, milk, and wheat.

Allergy symptoms can start a few minutes or hours after eating and include itching, burning, swelling of the tongue or mouth, a scattered red rash all over the body along with itching, nausea, vomiting, abdominal pain, and diarrhea. In severe cases, food allergies in children can cause difficulty breathing, low blood pressure, and loss of consciousness; this is a medical emergency requiring immediate attention as it can be life-threatening.

Allergic rhinitis and allergic conjunctivitis

Allergic rhinitis is one of the most common allergic diseases in children. Although the symptoms are not too severe, they often last for a long time and cause considerable discomfort.

When suffering from this common childhood allergy, children will frequently sneeze, experience itchy noses, runny noses, and nasal congestion, causing them to constantly scratch their noses and breathe through their mouths, especially while sleeping.

Allergic rhinitis can be accompanied by allergic conjunctivitis, causing children to have itchy eyes, frequently rub their eyes, and have watery eyes. Symptoms of conjunctivitis and allergic rhinitis can occur seasonally or year-round, depending on the type of allergen the child is exposed to.

Allergic diseases are more common in children who have family members with allergies.

Asthma

Asthma is also a common allergic disease in children. It is a chronic inflammatory condition affecting the airways, caused by an overreaction to irritants from the external environment. If two or more symptoms appear, the child needs to be examined and asthma ruled out. These symptoms include: chest tightness; wheezing; coughing; and recurrent shortness of breath.

Factors that can trigger or worsen asthma include strenuous physical activity, exposure to dust, pollen, other respiratory allergens, food, medications, and respiratory infections or allergic rhinitis.

Asthma is a common allergic condition in children. Episodes of breathing difficulties can limit their ability to participate in learning and recreational activities, cause sleep disturbances, and affect overall health if the condition is not effectively managed.

Atopic dermatitis

Atopic dermatitis is a common allergic condition in children, characterized by the appearance of small blisters on reddened areas of skin, often on the face and arms, or even scattered throughout the body. These blisters not only cause itching and burning sensations but also create conditions for bacteria to enter and cause infection when they rupture and release fluid.

Acute and chronic urticaria

Urticaria (hives) is a common allergic condition in children, usually manifesting as itchy red rashes all over the body. There are two types of urticaria: acute urticaria (the condition appears quickly and disappears within a short time) and chronic urticaria (the condition recurs many times over more than 6 weeks).

Hives can develop in isolation after the body is exposed to a new allergen, or they can appear as part of more severe allergic conditions.
