Recurrent urticaria is mainly due to its complex causes and susceptibility to various factors. We suggest you start by identifying the triggers and adjusting your lifestyle to gradually improve your condition.

The specific reasons may include the following:

1. Persistent allergens: If allergens such as food, pollen, and dust mites are not completely avoided, contact with them can easily trigger hives.
2. Fluctuations in physical condition: When fatigued, stressed, or experiencing changes in immunity, the body's sensitivity may increase.
3. Environment and lifestyle habits: Physical stimuli such as temperature changes, clothing friction, and alcohol consumption may also trigger symptoms.
4. Chronic infection risk: Some recurrent episodes may be related to underlying infections or chronic diseases in the body.
To reduce the risk of recurrence, you can try keeping a record of your daily diet and environmental exposures to help identify individual triggers; wear loose-fitting cotton clothing to avoid hot or cold stimuli; maintain a regular sleep schedule and manage stress appropriately. If symptoms occur frequently, please seek medical attention promptly for a comprehensive examination. Your doctor will develop a management plan tailored to your specific situation.
