Experts said: Recurrent attacks are one of the prominent symptoms of urticaria, erythema and wheal appear one after another, accompanied by severe itching. A few patients with visceral involvement may have symptoms such as fever, headache, nausea, vomiting, diarrhea and abdominal pain. In severe cases, it will also involve the larynx, causing shock such as dyspnea, and it is necessary to go to the hospital for diagnosis and treatment in time.
Why do more and more people get urticaria?
1, allergic constitution is hereditary.
If the mother is allergic, the child is 50% likely to be allergic; If the father is, the child has a 30% chance; If both parents are, the possibility of children's allergies is above 70%.
2, food, clothing, housing and transportation may cause allergies.
90% of food allergies are caused by milk, soybeans, eggs, wheat, peanuts, nuts, fish, shrimp and shellfish, and chemicals such as food seasoning, preservation, preservation and coloring are also dangerous substances that cause allergies; The paint, wallpaper and chemical fiber clothes we wear in the bedroom decoration may cause allergies; Also, life is always full of "newness". New electrical appliances, new cosmetics, new foods and even natural species such as flowers and trees have produced many new varieties under human interference, and the types of allergic pollen have also increased accordingly. The expansion of travel scope will inevitably increase people's chances of exposure to allergens.
3. Environmental pollution
A study found that even in healthy people, 70% of people will have symptoms such as itchy skin and wheal in persistent smog weather, and air pollution has become the main pathogenic factor leading to urticaria.
4. Raise awareness of disease prevention.
In the past, people were not very clear about allergic urticaria, and they often treated it as a skin disease. Now many people will take the initiative to go to the hospital to see allergies.
The treatment of urticaria is divided into four aspects:
1, avoid contact with allergens. This is the best treatment, but it is difficult to completely avoid allergens in real life. For example, people who are allergic to indoor dust mites should pay attention to simple furnishings, do not have carpets and bookshelves in the bedroom, and try to use quilt covers and sheets made of materials with anti-mite function for bedding to keep them ventilated, clean and dry; In addition, the temperature should be appropriate, because mites like warm and humid environment.
2. Symptomatic treatment. Because the etiology of urticaria is complex, traditional control and treatment methods, such as hormones, antihistamines and anti-inflammatory drugs, are mild for the time being, but the condition will get worse after a period of time, which will have a great impact on the body, and long-term use will cause damage to the liver and kidney. Old people and children should take it carefully.
3. Adjust allergic constitution (for treatment). Urticaria refers to the immune dysfunction caused by allergen stimulation, which causes the abnormal increase of immunoglobulin E(IgE) in vivo. Repeated contact with allergens causes IgE antibodies to be produced in the body and adhere to immune cells for a long time, which leads to the secretion of inflammatory mediators such as histamine, thus endangering the external manifestations of immune response. It can be seen that the fundamental treatment of urticaria lies in controlling IgE and regulating the balance of immunoglobulin.
Dr. Xie Peishan, director of the Taiwan Research Center of the Institute of Food and Applied Biotechnology of the National University of Taiwan Province Province, found that the use of anti-allergic probiotics Xin, Min and Kang can obviously alleviate the symptoms of allergic urticaria and effectively inhibit the production of specific IgE antibodies in vivo. Probiotics of Xin, Min and Kang can stabilize the balance of intestinal flora by colonization in the intestine, and stimulate immune cells by human microorganisms, which can reduce the production of specific IgE antibodies in serum, reduce the secretion of cytokines related to allergic reactions, reduce the stress response of immune cells to allergens, and make the disordered immune function tend to balance. After continuous use for more than 3 months, the concentration of IgE in the body decreases, so that allergens can no longer combine with IgE antibodies in the body, thus reducing the occurrence of allergic reactions.
If urticaria is serious, we should consider the combination of antiallergic drugs and antiallergic probiotics to get rid of the pain as soon as possible.
4. Daily prevention (preventive treatment). Urticaria is often accompanied by itching during the onset. At this time, patients should never scratch the affected area with their hands to avoid itching. You can use cold compress to relieve itching; Diet should be light, avoid irritating and allergic foods, keep the stool unobstructed, and use laxatives and soapy water enema when necessary; Ensure adequate sleep and enhance the body's immunity.
