High risk group of urticaria
1, people with bad eating habits: Because such people's improper diet will stimulate the emergence of urticaria, especially irritating foods such as pepper, onion, ginger and garlic, as well as pigments, seasonings, preservatives and synthetic substances contained in fast food will also cause urticaria.
2. People with infection symptoms: Because various infection factors can cause urticaria, infection is also a major cause of urticaria. Among them, the most common is the virus that causes upper respiratory tract infection and Staphylococcus aureus, followed by hepatitis, infectious mononucleosis and Coxsackie virus. Parasitic infections, such as roundworms, hookworms, schistosomiasis, filariasis, amoeba and plasmodium; Bacterial infection, such as acute tonsillitis, alveolar abscess, sinusitis, pustulosis, septicemia, etc.
3, people with allergic history: because allergies can also cause urticaria, such as pollen, dust, insect bites, animal dander, smoke, feathers, fungal spores, cosmetics and so on. There are sources of allergic urticaria in life.
4. People with bad working and living environment: urticaria can also be induced by physical and mechanical stimuli such as cold, heat, sunshine, friction and pressure.
How does urticaria happen?
Most urticaria is caused by allergic mechanism. Allergens in food (mostly heterologous proteins) stimulate the human body, causing the human body to produce specific antibody IgE (immunoglobulin E), which is attached to mast cells or basophils in the body. When eating this food again, IgE antibody will combine with allergens in the food, thus making mast cells and basophils release histamine. Histamine also acts on blood vessels, dilating blood vessels and increasing permeability, so a large amount of protein and liquid seep into skin tissue, resulting in urticaria.
Sometimes in life, we can see such a phenomenon: some people will have itchy skin after eating fish, shrimp, crabs and other foods, and then there will be wheal, which varies in size and shape, and the attack time is uncertain, and often recurs. These are all manifestations of urticaria allergic reaction. Substances that cause allergic reactions are called allergens in medicine. When the human body's function of resisting antigen invasion is too strong, allergic reactions will occur under the stimulation of allergens.
How should urticaria be treated?
1, away from allergens and allergic environments.
Usually, patients with urticaria will go to the hospital to draw blood to test allergens. Many times, I can't find the specific reason. Therefore, we suggest that patients should make records every time they have urticaria, see what they have been exposed to and find the source of allergies. For example, people induced by drugs should stop using allergic drugs; People who are allergic to food should not eat this kind of food after finding out the allergic food. Cold urticaria should pay attention to keep warm, acetylcholine urticaria can reduce exercise, sweating and mood swings, and contact urticaria can reduce contact opportunities.
2, adjust the allergic constitution
When we analyze the causes of urticaria, we will find a very strange phenomenon, that is, these factors, such as food, environment, mental stress and so on, are aimed at the general public. Why do some people have no allergic reaction or urticaria after contact or eating, while others are unfortunately shot? The result is obvious-everyone's physique is different. Deciding whether a person is allergic or not is the core of human immune dysfunction. Through the research of microbiologists, it is found that allergic patients are allergic because the activity of TH2 (type 2 T cells) in the body is too high, resulting in too many IgE antibodies. The health of immune system is closely related to intestinal microecological environment.
Modern medical research on microecology has found a new strain group of antiallergic lactic acid bacteria-Xinminkang probiotic patented product, which can reduce the activity of TH2 (type 2 T cells), enhance TH 1 immune response, and regulate TH2 immune response overreacted due to allergy by promoting the secretion of interferon γ. The main key is to seek alternative anti-allergic therapy other than drugs, and to improve the ecological balance of intestinal microorganisms, the largest immune organ of human body, by using active and non-pathogenic microorganisms, so as to promote the secretion of interferon and regulate the activity balance of immune cells. Xinminkang anti-allergic probiotics have the international patent certification for reducing serum IgE allergic antibody. After continuous supplementation for more than 12 weeks, the IgE concentration in the body decreased, so that allergens gradually failed to combine with IgE antibodies in the body, and thus allergic biochemical reactions no longer occurred. Xinmin Kang probiotics can solve the problem of recurrent allergic diseases. Compared with other treatment methods, firstly, the operation is very simple, it can be used at any time and has universality. Secondly, it will not be metabolized by liver and kidney like other drugs, thus avoiding the adverse reaction of drugs to human body; Compared with different desensitization treatments, there is no risk and no harm to the patient's body and mind.
3. Eliminate the recurrence factors of urticaria
Develop good living and eating habits, try to choose some loose cotton clothes, and often clean the affected area; Pay attention to your diet and usually avoid eating some spicy and greasy food. Patients can eat more fresh fruits and vegetables, which can improve their resistance. Try not to eat some seafood, mutton and beef, which may cause skin allergies. It is important to avoid overwork and ensure adequate sleep.
4. Improve immunity
Patients with urticaria can do more exercise in peacetime, which can not only enhance their physical fitness, but also improve their immunity.
