1. What is allergic urticaria
It has a certain relationship with exposure to a bad living environment or poor diet, and it is also It may be caused by contact with animal fur pollen, cold air, ultraviolet rays, mangoes, egg whites, etc. If the situation is serious, you can use anti-itching ointments to treat it, or you can use comprehensive oral medications for treatment. , for example, cetirizine hydrochloride tablets or loratadine capsules can be taken orally for treatment.
2. What is urticaria?
Urticaria as A \”familiar\” skin disease, its pathogenesis is relatively complex, coupled with its recurring \”characteristics\”, it troubles some people around us. The occurrence of chronic urticaria is not a decline in human immunity, but a disorder of cellular immune function, which may be related to the imbalance of the ratio of Th1 and Th2 in helper T lymphocyte subsets.
At the same time, patients with chronic urticaria have an hyperactive Th2 response and reduced Th1 function, which accelerates the production of immunoglobulin IgE by B cells in the body, and finally allergens or The IgEFc receptor on the surface of mast cells binds to IgE and activates itself to produce inflammatory factors that cause urticaria.
Thus reducing Th2 and I in the human bodyThe amount of gE is key. So where should we look for Th2 and IgE? Gut! The intestine is the largest immune organ in the human body and is home to a large number of microorganisms (approximately 1011 to 12 microorganisms per gram of intestinal content). After we are born, we are stimulated by a large number of microbial antigens and food antigens, causing intestinal mucosal lymphocytes to be activated, which in turn activates the intestinal mucosal lymphocytes. The systemic immune system matures.
Research shows that Th2-based cells play a key role in the onset of atopic dermatitis, and the rapid establishment of normal intestinal flora after birth can Downregulate Th2 immune response and reduce the occurrence of allergies. Therefore, using anti-allergic probiotics to help regulate the balance of intestinal flora and stabilize the immune system is key.
2009 HougeeS． The experiments were conducted using male mice aged 5-8 weeks. The experiment was sensitized with maoalbumin for one week; probiotics were administered intragastrically on the 28th day after the sensitization started, and the intragastric dose of each bacteria was 1 × 10 CFU/d until the end of the 42nd day.
The results show that the anti-allergic probiotics Bifidobacterium breve and Lactobacillus plantarum can reduce the amount of ovalbumin-specific IgE and IgG1, while plant Lactobacillus can also reduce the amount of IL-4, IL-5 and IL-10 in the blood of experimental animals. Bifidobacterium breve slows down the allergic reaction of the skin to ovalbumin. This anti-allergic probiotic can alleviate allergic symptoms. degree.
With the development of science, technology, medical theory and experiments, people’s understanding of the role of probiotics is no longer just about helping the intestines absorb nutrients. Bacteria, especially anti-allergic probiotics, can also help reduce the amount of Th2 and IgE in the human body, help stabilize the immune system of people prone to allergies, reduce the incidence of urticaria, and solve the problem from the root.
The above only represents the views of Monperland. I hope it can be helpful to you. Liminshu reminds you that although probiotics are beneficial to health, they must also be Use caution when comparing.

3. How to cause allergic urticaria
Drugs, many are often caused by drugs. Food, including fish, shrimp, crab, eggs, milk and other common causative factors containing special proteins. Inhalation. Various pollen, dust, etc. Physical and chemical factors. It is caused by physical and mechanical stimulation such as cold, heat, humidity, sunlight, friction and pressure, or by certain chemical substances entering the human body. It is recommended to find the allergen that caused your allergic urticaria and avoid exposure to it again in the future.
4. Is allergic urticaria contagious
It is not contagious. The disease often disappears naturally within an hour or two or a few hours, and within 1 to 2 days at most, but new lesions often appear one after another elsewhere, and no new lesions occur within 24 hours where the disease has disappeared. After the disease goes away, the skin returns to normal. Because the disease has no causative pathogen, it is not contagious.
5. What is urticaria
Urticaria attacks are better It\’s been years and it\’s still not getting better? Or the three things were not done
My skin had been itching for several months. When I went to the hospital, the doctor said it was \”chronic urticaria.\”

Chronic urticaria refers to a skin disease in which various factors cause temporary inflammation, congestion, and tissue edema in the skin, mucous membranes, and blood vessels.
When the course of the disease exceeds 6 weeks, it is called chronic urticaria. The causes are many and complex. The specific symptoms are sporadically occurring on the trunk, face, and limbs. Wheals and plaques, causing persistent itching. At the same time, frequent attacks and long-term treatment are also its characteristics.
How to get rid of \”annoying\” chronic urticaria?
There are two causes of chronic urticaria, one is internal causes and the other is external causes. External causes are mostly caused by allergens, while internal causes may It is caused by certain diseases, drugs, food, etc. Only by cooperating with the doctor\’s examination to find the specific causes and analyze them one by one can effective relief be achieved.
Currently, the mainstream treatments for chronic urticaria include antihistamine drugs, inhibition of hypertrophicCell degranulation drugs, glucocorticoids, immunosuppressants, non-specific anti-allergic therapy, traditional Chinese medicine therapy, etc.
The more commonly used are antihistamines, such as (Rainin) loratadine dispersible tablets, which are highly effective and long-lasting tricyclic antihistamines. Histamine drugs can relieve various symptoms caused by allergic reactions, such as allergic rhinitis and eye itching, and can also be used for chronic urticaria and itchy skin diseases.
One of the major causes of chronic urticaria is allergens. If you want to effectively reduce the occurrence of chronic urticaria, you must completely stay away from these allergens.
For example, pay attention to some allergic foods in your diet, such as peanuts, beef, eggs, seafood, etc. Of course, here are just some examples of common allergen-prone foods. Specifically, everyone is allergic to different points. The best way is to go to the hospital to receive a professional allergen test, so as to achieve the goal of staying away from allergens more efficiently. .
In general, for some patients with cold urticaria, they should keep warm and reduce exercise, sweating and mood swings. , contact urticaria reduces the chance of exposure to allergens, etc.

But if you want to completely get rid of chronic urticaria, you still need to take good care of yourself in life and pay more attention to yourself, so that chronic urticaria can get good treatment effects.
6. How to treat urticaria caused by allergies
If In this case, antihistamines are important drugs in the treatment of patients with various types of urticaria. Urticaria caused by allergies requires different treatment options depending on the severity of the condition. Urticaria is a common skin disease caused by various factors that cause temporary inflammatory congestion and large amounts of fluid exudation in the blood vessels of the skin and mucous membranes. Causes local edematous damage, which occurs and subsides rapidly and causes severe itching.
