1, caused by heredity
Studies have shown that chronic urticaria is often a polygenic genetic disease, manifested as genetic allergy. Under the action of various external allergic factors, the immune system of the body is disordered. It is worth mentioning that chronic urticaria is an immune dysfunction rather than immune hypofunction.
2, caused by allergens
After contact with allergens, urticaria may occur at this time. Like common animal fur, pollen, feathers and mosquito bites can all cause urticaria. Therefore, people who are prone to chronic urticaria need to stay away from these allergens in time to avoid adverse reactions after contact.
3, caused by diet
Diet also has a great influence on health. If you usually have a special reaction to certain foods, then these foods need to be taboo. Some people eat eggs, dairy products, fish, shrimp and crabs. At this point, urticaria will appear, indicating that these foods can also cause the disease.
4. Physical factors
Many factors may induce chronic urticaria, for example, common physical factors, such as cold and hot stimulation, sunshine, friction and other circumstances, may cause chronic urticaria. Therefore, if urticaria is caused by physical factors, it is necessary to rule out the influence of these bad factors. Therefore, we need to pay more attention in our daily life, otherwise it will lead to urticaria.
5. Influence
Common bacterial and viral infections may lead to chronic urticaria. It is found in the study that urticaria can also occur when people are infected with ascaris lumbricoides, hepatitis virus, upper respiratory virus and Staphylococcus aureus. It can be seen that viruses, bacteria, etc. Infection will also affect health.
6, caused by drugs
In daily life, we need to take medicine in time to treat diseases. However, it is necessary to pay attention to the safety of drugs in the process of medication, and some drugs will cause urticaria after use. Such as common serum vaccine, penicillin, etc. These drugs induce diseases through immune mechanism. In addition, common drugs such as morphine, aspirin and vitamin B 1 are histamine releasing substances, which easily lead to mast cells releasing histamine and causing urticaria.
When urticaria occurs on the body, the patient's skin will itch and even cause a serious blow to the patient's normal work and life. And urticaria can make people's skin look ugly, so everyone wants to quickly eliminate the symptoms of urticaria. In fact, they want to relieve the symptoms of urticaria and stop fidgeting. Patients can improve in the following ways.
1, removing allergic factors
Find out if there are allergic factors in your family, such as food and paint. Has been decorated, dressed up, etc. In addition, there are fish and shrimp, crabs, animal feathers, pollen, mushrooms, nettles, drugs, sunlight, bacteria, parasites and so on. May be allergic, so be sure to remove allergic factors or try to avoid contact. This can be fundamentally controlled, or you can do an allergen test and avoid contact with allergens after inspection.
2. Drug therapy
Mainly antihistamine treatment. Acute urticaria can choose mizolastine and loratadine. The second generation of non-sedative H receptor antagonists. When one drug is ineffective, two drugs can be used in combination. Chronic urticaria can be given in advance according to the law of onset, and stopped after a period of time (about one month) when the wheal is controlled. Due to drug resistance, the dosage can be gradually increased or different drugs can be changed frequently. Besides histamine, other inflammatory mediators such as leukotrienes are also involved in the pathogenesis of urticaria, so it is suggested to use drugs that can antagonize leukotrienes at the same time, such as mizolastine. Patients with chronic urticaria should take medicine strictly according to the doctor's advice. If the course of treatment is regular, the treatment effect will be better.
3, fundamentally immune regulation and anti-allergy.
The etiology of chronic urticaria is complex and involves many factors. In most cases, it is difficult to find a clear cause or inducement, so there is no treatment for the cause, so it is difficult to "eradicate".
From the immunology of urticaria, the fundamental treatment should be to control IgE, adjust the balance of immunoglobulin and improve allergic constitution. Xinminkang antiallergic probiotics added with six strains of Lactobacillus Roy, lactobacillus paracasei, Lactobacillus salivarius, Lactobacillus rhamnosus, Lactobacillus acidophilus and Streptococcus thermophilus. Patented strains contained in probiotics can activate cells to produce a series of physiological reactions by contacting with cells in intestinal tract, which can ultimately reduce the IgE of antibody immunoglobulin in human blood, fundamentally adjust allergic constitution, enhance immunity and improve the therapeutic effect of allergic diseases. Xinminkang can promote the secretion of interferon (IFN-Y), regulate TH 1 immune response, inhibit immunoglobulin IgE, and improve the allergic phenomenon of TH2 immune response. Reduce the production of specific IgE antibody in serum; Adjust allergic constitution, inhibit allergic reaction and prevent allergic recurrence; Adjust immune system, balance and enhance immunity.
4. Reduce chemical stimulation from outside.
Too cold, too hot, ultraviolet radiation and other conditions will aggravate patients' urticaria, so we should pay attention to avoid all kinds of external stimuli to the skin at ordinary times, do a good job of sun protection before going out, keep warm when the weather is very cold, wear gloves when washing clothes at ordinary times, and use mild and irritating bath products or not to use bath products when taking a bath to avoid urticaria being stimulated and aggravating the condition.
