Experts said that in the last six years, the prevalence of urticaria in China from 15% to 25%, the number of patients increased by 100 million. Visible urticaria incidence of wide-scale, the damage is also quite large. Especially in the cold winter, urticaria presented on the body, itchy red, the more you scratch, the more itchy, bitter. Why is this?
How are hives formed?
Our intestinal immune system is the forefront of the fight against intestinal bad bacteria, because the intestinal surface area is the largest, and contact with foreign bacteria is also the most, the basic function of the intestinal tract is to absorb the nutrients of the food, because nutrients are the main source of maintenance of the body's health, therefore, the intestinal immune defense system must be able to distinguish between the nutrients and bacteria, so that the nutrients of the food pass through the mucous membrane of the small intestine smoothly, and will not be rejected by the immune system, and achieve the defense and absorption of the food, and the immune system will be the most important thing. The immune defense system must be able to distinguish between nutrients and bacteria so that food nutrients can pass through the mucous membrane of the small intestine without being rejected by the immune system.
When our intestinal immune system senses that bacteria are approaching, the immune cells will secrete immunoglobulin A (IgA) to attack the bacteria; and if the food component is close to the food, it will automatically secrete immunoglobulin E (IgE) or G (IgG), which will cause allergic reactions when immunoglobulin E is secreted in excess.
In the intestinal immune system, there is an "immune tolerance" mechanism that inhibits the immune system from secreting IgE or G (IgG), which can trigger an allergic reaction, in response to random food ingredients. In the case of an allergic person, it is because of a problem with the "immune tolerance" mechanism that the intestinal immune system secretes too much immunoglobulin E (IgE) to attack a particular food ingredient when the person eats it, resulting in hives.
Urticaria is typically IgE-mediated, caused by IgE-mediated degranulation of mast cells to release inflammatory mediators such as histamine. Increased capillary permeability produces a windswept rash. Vasodilatation causes erythema, inflammatory mediators stimulate receptors causing itching. The classical theory is that antigen binding to specific IgE on skin mast cell surface receptors stimulates mast cells to release histamine and other inflammatory mediators, and the most researched pathogenesis of chronic urticaria is the theory of IgE-mediated autoimmune disease, which has been proved to be sufficient basis: in most patients with urticaria, there are antibodies against functional anti-IgE receptors capable of degranulation of cutaneous mast cells or eosinophils and anti-IgE antibodies, serum immunity, and serum immunity. IgE antibodies, serum immunological examination of total IgE is higher than normal, or eosinophils or neutrophils are high, through the examination of skin tissue extracts, found that the level of histamine is increased in the rash and non-rash areas, histamine-releasing factor can make mast cells and basophils activated to release histamine.
Scientific proof: hives patients immune system IgE immunoglobulin to be 1-10 times higher than normal, these high IgE will disrupt the body's immune system, so that it produces sensitivity to the body, which leads to the production of hives, so as to strengthen the hives immune defenses to improve the ability to adapt to the environment.
What should I do if I have hives?
1, away from allergens
Hives is a kind of allergic skin disease, want to get the condition under control as soon as possible, want to prevent the recurrence of hives, we have to find their allergens. It is best to go to the hospital to check what their allergens are, only as soon as possible to find out the allergens, life away from these allergens, hives will not recur. There are many different allergens in life, and it is troublesome to implement them if you only look for them on your own.
2, improve the allergic body
Traditional treatment of urticaria often can not grasp the cause of targeted treatment, more than the use of internal antihistamine drugs, corticosteroids temporary inhibition of more than a long period of time or a large dose of external use of corticosteroid drugs, will be addicted to lead to drug dependence, the most common is the use of medication to improve the condition of the drug, once the drug is discontinued, the drug parts of the primary lesions aggravated. It is recommended to reduce the number of recurrent urticaria attacks by immunomodulation of the allergic body.
Modern medicine through the study of urticaria found that supplementation of anti-allergy probiotics can improve the allergic body from the inside. The root cause of urticaria is the patient's physical problems and the imbalance of immunoglobulin (IGE) secretion, which results in high IGE values. In our treatment, we have to start from the root to reduce the IGE value and balance the immunoglobulin.
Numerous animal studies and clinical trials have provided strong evidence that increasing the number of probiotics in the digestive tract can prevent and even treat urticaria. The six patented strains of bacteria used in Xinminkang Anti-Allergy Probiotic are scientifically formulated to improve the ecology of probiotics in the intestinal tract, enhance the ability to travel throughout the body and regulate the immune function of the whole body to alleviate the symptoms of allergy; Xinminkang Anti-Allergy Probiotic, which is made up of a composite of six strains of bacteria, can reduce the high level of serum Iglobulin in the serum of patients suffering from allergic rhinitis by enhancing the TH1-type immune response and regulating the overreaction of the TH2-type immune response due to allergy. It reduces the high IgE-specific antibodies in the patient's serum, relieves allergic symptoms, adjusts the allergic body, produces a good overall efficacy compared to the simple drug treatment of urticaria, and effectively improves the quality of life of allergy sufferers. Compared with a single anti-allergic strain immunomodulation anti-allergy ability is more comprehensive.
3, do a good job of daily care
To diet to keep light. In normal times should drink more boiled water, but also can drink some fruit juice and honey in moderation, can play a role in moisturizing and maintenance of the skin, can alleviate the symptoms of itchy skin. Usually should also drink more mung bean porridge and seaweed soup, can play the role of anti-inflammatory and antibacterial, is also conducive to the improvement of urticaria. Eat more fresh green leafy vegetables and fruits, can play the role of heat detoxification, so patients should eat more fruits and vegetables and other foods.
To ban spicy food. In normal times, you should avoid eating spicy hot and hot pot food, and can not often eat chili, do not eat easy to cause the body on fire stimulating food, do not drink alcohol and smoking, do not drink carbonated beverages.
Because of the itchy skin, children will keep scratching and even cause secondary infections by rubbing the skin. Parents should keep their children's fingernails short to avoid contaminating the wound with bacteria from the nails. Ointments can be applied to relieve the itching as prescribed by your doctor. Hot water can be used to localized hot compresses, can dilate blood vessels, help release allergens, but hot compresses must be wiped clean with a dry cloth, while taking good care of, to avoid re-exposure to irritation.
