Autumn Urticaria: What's Going On and What to Do

Generally, autumn urticaria may be caused by factors such as heredity, cold air stimulation, contact with allergens, insect bites, and viral infections. Patients are advised to choose general treatment, medication, or other approaches under a doctor's guidance to alleviate symptoms. A detailed explanation is as follows:

1. Heredity: Urticaria has a certain hereditary tendency. If someone in the family suffers from urticaria, other family members may have a relatively higher probability of developing it, and symptoms may appear in autumn. Urticaria caused by hereditary factors may be accompanied by skin wheals, redness, itching, and symptoms may recur repeatedly.

2. Cold air stimulation: In autumn, as temperatures drop, exposure to cold air may trigger urticaria. Cold air-induced urticaria is usually accompanied by symptoms such as skin wheals, redness, and itching, which appear rapidly after exposure to cold air. Patients should keep warm and avoid prolonged exposure to cold air.

3. Contact with allergens: There are many allergens present in the autumn environment, such as pollen, dust mites, and animal dander. Contact with these allergens may trigger urticaria. After exposure to allergens, patients may experience symptoms such as skin wheals, redness, and itching. In severe cases, symptoms of anaphylactic shock such as difficulty breathing and swelling of the throat may also occur.

4. Insect bites: Autumn is an active season for insects, and insect bites may lead to urticaria. After being bitten, the skin may develop symptoms such as redness, swelling, itching, and pain, and may also be accompanied by blisters or pustules. It is recommended to take protective measures such as using insect repellent and wearing long-sleeved clothing to avoid insect bites.

5. Viral infection: Autumn is a high-incidence season for respiratory infections, and viral or bacterial infections may trigger urticaria. Urticaria caused by viral infection may be accompanied by respiratory symptoms such as fever, coughing, and runny nose, as well as skin symptoms such as wheals, redness, and itching. Maintaining a regular lifestyle, engaging in appropriate physical exercise, and enhancing immunity can help reduce the occurrence of urticaria caused by viral infections.

Patients experiencing urticaria in autumn should follow medical advice to use medications such as ephedrine hydrochloride and diphenhydramine tablets, cetirizine hydrochloride tablets, and fexofenadine hydrochloride tablets. At the same time, avoiding contact with possible allergens can help reduce the occurrence of autumn urticaria.
