Causes of urticaria:
1, the incidence of urticaria is mostly related to contact with allergens.
Food allergy is one of them, for example, many children get urticaria because they eat additives, preservatives and pigments in fish, shrimp, crabs, eggs or snacks.
Drugs are another urticaria allergen, such as penicillin, thiamine and serum vaccine. Some people will be allergic to these drugs because of immune reaction.
Inhalation allergy is also easy to induce urticaria, and pollen, dust, animal dander and volatile chemicals are the most likely to induce allergic reactions.
Infection factors such as bacteria, viruses, fungi and parasites often cause urticaria, such as Staphylococcus aureus, infectious mononucleosis and Coxsackie virus, which are common allergens, so we must pay attention to hygiene every day and wash our hands before and after meals.
2. Urticaria is actually an allergic disease and a manifestation of allergic constitution. And our physical changes are closely related to our immune ability.
There are two ways for a healthy immune system ──Th 1 and Th2. These two ways need to be balanced. If Th2' s immune mode is too active, it will cause allergy. The immune system of people with allergic constitution is excessive excretion of TH2 and lack of excretion of TH/kloc-0, which leads to the imbalance of human immunity. Allergy is an immune disease, which is an imbalance of human immune function. In clinical investigation, patients with allergic constitution often find that multiple allergic diseases can be seen in the same patient. Compared with normal people, patients with allergic constitution have significantly higher serum IgE, more mast cells and more IgE receptors on cell membrane. Clinical medicine has proved that helper T cells and their cytokines play an important role in regulating the composition of IgE. According to the secretion of cytokines, helper cells are divided into two subgroups: TH 1 and TH2. Cytokines secreted by TH2 cells play an important role in antibody formation and allergic reaction. TH 1 and TH2 are regulated by cytokines. Under healthy conditions, TH 1 and TH2 are simultaneously balanced and regulated by helper T cells. When helper T cells lack regulatory ability or come into contact with some foreign proteins or small molecules (such as dust mites, pollen or seafood, etc.). ), TH2 is over-activated, which leads to the excessive secretion of TH2 cell hormones, leading to the increase of IgE and serum IgE concentration.
The harm of urticaria not treated in time;
Urticaria will develop into chronic urticaria if it is not treated in time, leading to wheal and erythema on the skin, accompanied by severe itching, abdominal pain, diarrhea, nausea, vomiting and other gastrointestinal symptoms. Some patients will also have difficulty breathing, accompanied by palpitations and chest tightness. At this time, if not rescued in time, the patient will die due to insufficient blood supply and failure of important organs.
Urticaria is sometimes accompanied by severe itching symptoms, which will greatly reduce the quality of sleep and greatly affect daily life. It is easy for patients to become impetuous and normal life cannot be carried out. The skin surface will be red, swollen and painful, and severe skin allergy will cause slight desquamation or even cracking, which will seriously affect the patient's skin, make the skin lose luster and affect the appearance.
Urticaria can damage people's image. In the face of other people's strange eyes, many patients become unconfident, gradually away from the crowd, lack of communication for a long time, and have great psychological pressure, which is easy to make patients suffer from mental illness. Therefore, measures should be taken in time to deal with urticaria.
Correct conditioning methods for urticaria;
1, find allergens or avoid eating common allergic foods. Urticaria is mostly related to inhaled allergens, such as dust mites, mold and pollen. Contact should be strictly avoided after allergen identification. Avoid second-hand smoke and odor in life, and eat less sweet, salty and spicy food.
2. In the face of urticaria, people can only use antihistamines or steroid drugs to suppress the inflammatory reaction, which means that they can only alleviate the manifestations of allergies and do not deal with the fundamental problems of allergic attacks. Basically, after taking drugs, it will relieve itself, and once it stops taking drugs, it will continue to attack. In this way, patients will begin to worry about the harm caused by taking antihistamines for a long time. In recent years, after many discussions on allergy science, immunologists have found that people with allergic diseases or allergies can improve their immune system without any side effects if they eat some bacteria that are beneficial to the human body. The concept of new Kangmin anti-allergic probiotics regulating their own allergies is increasingly recognized by everyone.
TH2 immune response can be adjusted to TH 1 immune response through the participation of anti-allergic probiotics of xinminkang. The patented strains (Lactobacillus salivarius, Lactobacillus Roy, lactobacillus paracasei, Lactobacillus rhamnosus, Lactobacillus acidophilus, Streptococcus thermophilus) contained in it are fixed on the intestinal mucosa after taking, which can regulate the unbalanced immune system from the immune system, thus slowing down the occurrence of allergies. IgE is a biological indicator of allergy, and the IgE of people with allergic symptoms is much higher than that of normal people. Animal experiments have proved that Lactobacillus salivarius contained in Xinmin Kang probiotics can help to reduce the production of specific IgE antibodies in serum, promote the secretion of IFN-γ by spleen cells, and enhance the TH 1 immune response, thus regulating the TH2 immune response overreacted due to allergies and reducing the production of specific IgE antibodies in serum, thus regulating allergic constitution, inhibiting allergic reactions and preventing allergic recurrence.
3. Patients with urticaria should pay attention to a balanced diet and eat less greasy, sweet, irritating food, tobacco and alcohol. Some foods are also allergens, so we should pay attention to distinguish them. Eating more foods rich in vitamins can enhance the body's immune ability.
At the same time, some light foods rich in vitamins and plant proteins, such as soybeans, brown rice, buckwheat, bean products, chestnuts, carrots, Chinese cabbage, green peppers, fruits and low-cholesterol dried fruits. , should be more intake, usually diet should be nutritious, improve the body's immunity, but also reduce the occurrence of allergic symptoms. Of course, if you can cooperate with proper exercise and keep an optimistic mood, it will be very helpful to improve your allergic constitution.
Nowadays, many families keep small animals. Children with urticaria should avoid keeping small animals, because their hair is easy to breed bacteria, and cat hair carries the most bacteria among pets. Children should be actively encouraged to participate in sports, but preventive measures should also be taken to avoid excessive exercise. Because dust mites are easy to attach to fur dolls, it is best not to put fur dolls on children's beds. If you must put fur dolls, it is best to wrap them in plastic bags or wash them with hot water once a week, or put them in the refrigerator for two hours every week to prevent dust mites from breeding.
