When urticaria occurs, patients will have different degrees of itching, which seriously affects their normal life and work. Therefore, we must understand the cause of urticaria and try to avoid such diseases.
Why does urticaria always recur?
1, contact with allergens
Allergy to viruses, drugs, food and mental stress can cause urticaria. If patients don't know their allergens, repeated contact will lead to illness. The most common allergens are dried fruits, seafood, milk, aspirin, antibacterial drugs, pollen, flying flocs, pet dander, strong sunlight, cosmetics, skin care products and so on. Patients should go to the hospital for a blood test to find out what they are allergic to, and don't touch them again in the future to prevent the disease from recurring.
2, allergic constitution
It is scientifically proved that the immune system IgE immunoglobulin of patients with urticaria is 1- 10 times higher than that of normal people. These higher IgE will disturb the immune system of human body and make it sensitive, which will lead to urticaria. If one of the parents is allergic, the probability of the next generation of allergic constitution is quite high, and the probability of urticaria is much higher than that of ordinary people. In addition, with the growth of age, changes in the environment, anxiety and other neurological factors are easy to cause allergies and urticaria.
3. Frequent hormone therapy
If patients with urticaria use drugs containing hormones for the first time, it may lead to recurrent attacks. Although hormone drugs are faster in treatment, they are prone to dependence and drug resistance. Long-term drug abuse will lead to recurrent attacks and increase the difficulty of treatment. Patients must stop taking drugs in time to avoid bringing more side effects to the body. In addition, they should choose a good treatment plan and try to use antihistamines to stabilize the condition. Although taking medicine for a long time, as long as you insist on taking medicine, you can cure the disease.
4, excessive scratching
When urticaria occurs, the patient will have a rash and itching is unbearable. Because you can't stand itching, you will scratch too much with your hands, thus destroying the surface cells of the skin, causing a large number of bacterial infections, causing skin lesions, making the skin thicker and rougher, leading to repeated attacks. You can wipe the place with urticaria with warm water every day, which can relieve itching and pain, relieve dilated capillaries, help the recovery of the disease, and clean up bacteria. Never burn yourself with hot water, or it will aggravate your condition.
Why is urticaria more uncomfortable at night?
1, allergic factors increased. Urticaria patients will come into contact with pillows, quilts and other supplies when they sleep, and these supplies often contain some sundries, which are easy to hide some bacteria or particles, which will easily aggravate the symptoms of urticaria patients, thus making urticaria attack at night.
2. Less external interference. Patients with urticaria should try to avoid contact with allergens, but that does not mean that patients should avoid contact with all external interference. Under normal circumstances, the human body will be less active at night, which will easily reduce external interference, leading to the increase of patients' own sensitivity, thus making urticaria attack at night.
3. Decreased hormone secretion. Decreased hormone secretion is an important cause of nocturnal urticaria. This is because most drugs for treating urticaria contain hormones, which are secreted most in the morning and relatively less at night. Therefore, the inhibitory effect of hormones on urticaria will be significantly weakened at night.
4, the human body function is weakened. The function of the human body tends to weaken at night. This is because the human blood circulation is slow at night and the skin lacks nutrition, which often leads to urticaria at night.
Urticaria recurs, how to prevent it?
1. Find out the cause of the patient's illness or aggravation, and avoid external bad stimulation: learn about the medical history, working environment, living habits, thoughts and emotions in detail; Allergen examination, such as skin prick test or intradermal test, specific IgE antibody and patch screening test. To find possible allergens. Try to avoid bad external stimuli, such as hot water washing and severe scratching; Try not to wear chemical fiber underwear and fur products; Avoid allergic and irritating foods, such as seafood, peppers, wine, coffee, etc.
2. Oral antihistamines: such as loratadine, chlorpheniramine and cyproheptadine. It can compete for histamine in the body, thus effectively relieving skin allergy symptoms. But antihistamines can't inhibit the production of histamine, so they can't prevent urticaria from recurring. Moreover, histamine products have the function of inhibiting nerves, and are prone to dizziness, drowsiness and other adverse reactions after taking them, and long-term use will cause great damage to liver and kidney.
3. Allergic probiotics: Urticaria mostly belongs to type I allergic diseases (also known as IgE-mediated allergic reactions). From the immunological point of view of urticaria, the fundamental treatment should be to control IgE and adjust the balance of immunoglobulin. At present, the treatment of urticaria mostly stays in the inflammatory stage such as antihistamine, and some people try to treat it by improving immunity, but allergies are not caused by low immunity. The imbalance of five kinds of immunoglobulin secretion in human body is the fundamental cause of the disease.
At present, the treatment method of IgE antibody to solve urticaria in international immunology research is mainly to reduce IgE antibody in vivo by supplementing a large number of anti-allergic probiotics Xinmin Kang, and to adjust the balance of immunoglobulin by stimulating interferon secretion, thus restoring the immune response of human body. The patented strains such as Lactobacillus salivarius, Lactobacillus Roy, lactobacillus paracasei, Lactobacillus rhamnosus and Lactobacillus acidophilus selected by Xinmin Kang's antiallergic probiotics are scientifically matched. Compared with Bifidobacterium, they have stronger acid resistance, better bile salt resistance, better high temperature resistance, long-term activity at room temperature, and direct access to intestinal tract after taking, thus exerting the greatest antiallergic effect.
4. Control emotions and restore a healthy life: The pace of life of contemporary people is tense, and many people often have irregular work and rest and irregular diet. Lack of sleep, fast food takeout is too normal for them. It is also based on this that more and more people suffer from urticaria. If you are in a state of tension and anxiety for a long time, the endocrine in the human body will continue to change, greatly increasing the risk of illness. Cholinergic urticaria is caused by mental and emotional stress. When you are extremely nervous, the excited cholinergic nerves in your body will release acetylcholine. If the body is allergic to this substance, it will show allergic reaction and cause urticaria. In addition, some teenagers have urticaria because of excessive psychological pressure and mental tension. Therefore, keeping a peaceful mind and living a regular life can effectively relieve mental stress.
