Many parents know that pollen and animal dander cause skin allergies, but certain foods are also major culprits. So how do you identify your child's allergens?
Food Diary
Record the types of food consumed each month, along with the time of ingestion (e.g., month, day, hour) and the onset of allergic reactions. When an allergic reaction occurs, you can use these records to trace the connection between the food and the reaction.
Skin Tests
These are typically performed in dermatology or respiratory departments. While the method is simple and easy to follow, it's difficult to obtain precise results.
Generally, pay close attention to foods consumed 12 to 24 hours before an allergic reaction. Though straightforward, this approach yields less accurate results.
Typically, focus on foods consumed 12 to 24 hours before symptoms appear. While this method is simple and easy to follow, it can be challenging to obtain precise results.Using an empty syringe, draw up skin test solutions containing milk, rice, soybeans, etc. Multiple pricks on the upper arm allow observation of allergic reactions to various foods. However, due to the complex digestion and absorption processes of food in the body, even if the results are positive, clinical analysis is required to ultimately determine if the food is the cause of the allergy.
To determine if a specific food is allergenic, multiple methods must be combined with clinical observations for a final decision on whether to eliminate it from the diet. Even if elimination is necessary, it should not be prolonged, and too many foods should not be restricted simultaneously to avoid impacting the child's growth, development, and overall health.
Allergen testing for children can be categorized into in vivo and in vitro tests.In vivo testing: Allergens are applied to the body via skin tests or prick tests to observe reactions and determine if the patient is allergic to them. In vitro testing: Blood or other bodily fluids are collected for detached testing, without direct application of allergens to the body. Identifying a child's allergens is crucial, and proactive treatment is essential.So, what should you do if your child has allergies?
Tip 1: Prevent scratching behavior
Skin allergies in babies often come with itching, leading them to scratch uncontrollably. The more they scratch, the worse the itching gets. If this behavior is left unchecked, it creates a vicious cycle: "itchy → scratch → more itchy → scratch again."
Tip 2: Promptly clean saliva and sweat
If your baby drools, wipe it away promptly. Additionally, maintain appropriate indoor temperature and humidity to prevent sweating. Avoid secondary irritation to your baby's delicate skin from saliva or sweat.
Tip 3: Avoid Allergens
When your baby has a skin allergy, remove them from triggering environments. Keep them away from pollen, mold, dust, trees, tobacco smoke, fumes, perfumes, gasoline, paint, pesticides, cleaning agents, medications, pets, carpets, and other allergens.
Tip 4: Apply Moisturizer After Bathing
Reduce excessive bathing and avoid harsh soaps. Immediately after bathing, apply a gentle, non-irritating moisturizer that can mildly treat your baby's skin allergies.
Tip 5: Identify Allergens Through Medical Testing
Numerous factors can trigger allergies. To pinpoint the culprit, take your baby for allergy testing at a hospital. Once the allergen is identified, immediately eliminate exposure. Allergic reactions typically subside naturally thereafter.
