Common triggers for acute urticaria include allergies, infections, and other factors. The cause can usually be identified through a doctor's consultation and necessary examinations. It is recommended to seek medical attention promptly upon the onset of symptoms for evaluation by a professional physician.
1. **Common Triggering Factors**: Many factors can trigger acute urticaria. For example, consuming certain foods (such as seafood and nuts), taking certain medications, or being bitten by insects can all cause allergic reactions. In addition, infections such as colds and pharyngitis caused by viruses or bacteria are also common triggers. Mental stress, high pressure, or physical stimuli (such as friction or changes in temperature) can also induce hives.
2. **Possible Tests:** During diagnosis, the doctor will first ask a detailed question about your medical history, recent diet, and exposure, which is crucial for determining the cause. If a specific allergen is suspected, the doctor may recommend allergen testing, such as a skin prick test or a blood test for specific IgE antibodies. These tests help identify possible allergens, but not all cases will definitively identify a single cause.
When you develop acute urticaria, record any suspicious items or foods you came into contact with before the onset of the flare-up and consult a dermatologist promptly. Treatment primarily involves using antihistamines under a doctor's guidance to relieve itching and wheals, and avoiding identified triggering factors as much as possible. Do not self-medicate or rely on folk remedies.
