Why does urticaria disappear soon? What is the mechanism?

Most skin lesions and rashes of urticaria will naturally subside after a few hours, leaving no trace. But it will happen again and again, and new wind masses will grow irregularly. The wheal will turn white, the surrounding area will be red, and the skin will look like orange peel. The wind is itchy. If you scrape hard, the wind mass will increase and merge with each other to form a large piece. Therefore, timely and effective treatment of urticaria is the key to relieve urticaria.

How is urticaria caused?

1. Pollen: In the season of abundant pollen, tiny pollen particles can be scattered in the air and fly around in the process of transmission. Some of them will be inhaled and absorbed by the skin, and some people will cause urticaria.

2, food: food allergies can also lead to urticaria, such as seafood, mango, nuts, the most likely to cause chronic urticaria.

3, seasonal changes: seasonal changes will lead to changes in the environment, bacterial spores and pollen in the air will release a lot of histamine, thus causing chronic urticaria.

What should urticaria avoid?

Precautions for patients with urticaria Patients with chronic urticaria should pay attention to diet and avoid incentives. The incidence of urticaria has a certain relationship with diet, and some foods may be the cause. For example, fish, shrimp, seafood, canned food containing artificial additives such as artificial pigments, preservatives and yeast, pickled food and beverages can all induce urticaria. In addition, irritating foods such as too hot and sour will also reduce the digestive function of the gastrointestinal tract, making food residues stay in the intestine for too long, thus producing peptones and peptides, increasing the probability of human allergies. Patients with chronic urticaria should pay attention to hygiene and avoid bad stimulation.

People with a history of urticaria should pay attention to keeping indoor and outdoor clean, and keep fewer pets such as cats and dogs at home. Avoid inhaling pollen, dust, etc. Avoid wind, cold, heat, dampness, dryness, fire and insect poison. Live regularly to adapt to changes in the external environment. Drinking, heating, emotional excitement, exertion, etc. It will aggravate skin vasodilation and stimulate or aggravate urticaria. Rubber gloves, hair dyes, soaps and detergents, chemical fibers and wool clothes may be bad stimuli for patients with allergies or urticaria and should be avoided.

What should I insist on when urticaria attacks?

1, concentrate on turning the force, and don't always tickle the parts:

Under normal circumstances, it is very uncomfortable to say that urticaria is itchy. So many people choose to shave. Generally speaking, the scratching process will aggravate the symptoms of urticaria. And at night, if we cover the quilt too thick, it will also lead to itching. Therefore, when urticaria attacks, we try to divert our attention from the itching spot. When you focus on another thing, the itching will be alleviated. This can prevent the bacterial infection of urticaria and avoid aggravating the symptoms of urticaria!

2. The new concept of measles treatment: the immune function of human body is disordered due to the stimulation of allergens, which makes the immunoglobulin E in the body abnormally increase. Repeated contact with allergens leads to a large number of IgE antibodies in the body, which attach to immune cells for a long time, leading to the secretion of inflammatory mediators such as histamine, which is harmful to itself. From the immunological point of view of urticaria, the fundamental treatment should be to control IgE and adjust the balance of immunoglobulin.

IgE antibody immunomodulator, Xinmin Kang probiotics and urticaria mostly belong to type I allergic diseases (also known as IgE-mediated allergic reactions), and their causes are complex. Generally, it will turn from acute urticaria to chronic urticaria, which will recur for a long time and cannot be cured for a long time. At present, people only pay attention to the treatment of urticaria, but not the allergic reaction itself: the stimulation of allergens leads to the disorder of human immune function and the abnormal increase of immunoglobulin E in the body. Repeated contact with allergens leads to a large number of IgE antibodies in the body and attached to immune cells for a long time, which leads to the secretion of inflammatory mediators such as histamine and harms itself. From the immunological point of view of urticaria, the fundamental treatment should be to control IgE. At present, the treatment of urticaria mostly stays in the inflammatory stage such as antihistamine, and some people will try to treat it by improving immunity, but allergy is not caused by low immunity, and the imbalance of five immunoglobulin secretion in human body is the fundamental cause of the disease. At present, the treatment method of IgE anti-human antibody to solve urticaria in immunological research is to reduce IgE antibody in vivo by supplementing a large number of Xinmin Kang probiotics, and to adjust the balance of immunoglobulin by stimulating interferon secretion, so as to restore the correct immune response of human body.

3, beware of ultraviolet sunburn

Ultraviolet sunburn, also known as solar dermatitis, is mainly a local skin allergic reaction caused by excessive ultraviolet irradiation in the sun. Erythema and blisters appear on exposed skin such as neck, face, arms, shoulders and back, which are as painful as burning. If it is not handled properly, it will leave pigmentation. Solar dermatitis is a common skin allergic disease in summer. When you go out, you must take protective measures to avoid prolonged sun exposure.
