Childhood urticaria is usually caused by a variety of factors, including allergic reactions, infections, or physical irritants. Parents can pay attention to the things their child comes into contact with daily and keep a record of any flare-ups, which will help doctors determine the cause.
Specifically, common triggers mainly include the following:
1. Food or drug allergies: Foods such as eggs, milk, and seafood, or certain medications, may trigger allergic reactions in the body.
2. Infectious factors: Viral or bacterial infections such as colds and pharyngitis in children can sometimes be accompanied by urticaria symptoms.
3. Physical stimuli: These include skin pressure, changes in temperature, sun exposure, or scratching, all of which can trigger hives.
4. Other factors: such as mosquito bites, contact with pollen, pet dander, etc., may also cause rashes in children with sensitive skin.
If your child develops hives, it's recommended to first prevent scratching and temporarily stop introducing any new foods that may trigger an allergy. Observe whether the rash subsides on its own within a short period. If the rash recurs, is accompanied by difficulty breathing or facial swelling, seek medical attention promptly. Maintaining a clean home environment and keeping records of your child's diet and activities can provide valuable information for your doctor during consultations.
