Skin allergies are most likely to occur when the weather changes or when the seasons change. The most uncomfortable thing is hives, which is unbearable. It is a very common problem in dermatology clinics. Nearly one out of every five people has urticaria, in addition to severe redness, swelling and itching, and even often attacks in the middle of the night, which seriously affects sleep and life, and must be detected and treated as soon as possible.
What is hives
Urticaria is an acute allergic phenomenon of the skin. A sudden, red, itchy rash on the skin that usually lasts for a day and goes away, but can then occur in another part of the body. In severe cases, it is often accompanied by swelling of the larynx, difficulty swallowing, and swelling of the eyelids and lips.
Common classification of urticaria
1. Acute urticaria: acute attack, all of a sudden wheal all over the body, fast to come, fast to go, most of the attack two or three days, the longest two weeks will heal on their own.
2. Chronic urticaria: when it recurs for more than six weeks, even all year round, especially at night. Causative factors are difficult to find, or even impossible to find.
3. Inducing causes of urticaria: physical (cold, heat, sunlight), cholinergic, compressive, contact, etc.
What conditions can trigger hives:
(1) Food: This is the most common cause of acute urticaria. For example, fish, shrimp, crab and eggs are more common, but also wine, cola, chocolate, certain seasonings, mangoes, mushrooms, bamboo shoots, herbs, etc.
(2) Infection: When the body has bacterial infection, mold, tooth suppuration, chronic sinusitis, etc., it will also cause chronic urticaria, which we are often overlooked.
(3) External contact: bitten by fleas and bed bugs, or exposed to allergens in the environment, such as pollen, dust, sprays, etc. in the air.
(4) Internal factors: physical diseases such as lupus erythematosus, thyroiditis, hepatitis, rheumatoid arthritis, etc., and psychological factors, such as emotional stress, mental pressure, and sleep disorders, will also be induced.
(5) Physical factors: As long as it is scratched or pressed, it will be caused by heat, cold, or even water, and some people will be exposed to sunlight.
Treatment and improvement of urticaria:
1. First of all, it is necessary to seek medical attention and find out any possible causes first. Chronic urticaria often has no cause or trigger and needs to be treated with long-term treatment. However, many patients who relapse and believe that treatment is ineffective, abandon treatment or turn to home remedies, often making the disease more difficult to control.
2. Oral antihistamine to control the condition and control the occurrence of allergic reactions.
3. Avoid contact with all triggers, such as drinking, soaking in soup, high water temperature, and tight clothing.
4. Dietary adjustment: Avoid pseudoallergens in the diet, and appropriately supplement vitamin D6.
5. Anti-itch syrup, cold shower, or cold compress can also be used to relieve the attack. (Except for patients with cold causes.) ）
6. Develop regular work and rest habits, and appropriately release life pressure.
