The skin is a very important organ of the human body and the largest organ of the human body. The skin is also a very fragile organ because it is in direct contact with the outside world. Urticaria is a relatively common skin disease. There are many types of urticaria, among which allergic urticaria is a relatively common disease.
Urticaria, commonly known as wheals, is a localized edema reaction caused by the dilation and increased permeability of small blood vessels in the skin and mucous membranes. The clinical manifestations are wheal lesions of varying sizes, which occur suddenly, subside quickly, and cause severe itching, leaving no trace after recovery. Allergic urticaria is caused by various factors that cause temporary inflammatory congestion and large amounts of fluid exudation in the blood vessels of the skin and mucous membranes. Cause local edematous damage. It occurs and subsides rapidly, with severe itching. There may be fever, abdominal pain, diarrhea or other systemic symptoms. It can be divided into acute urticaria, chronic urticaria, angioedema and papular urticaria.
The common causes of urticaria can be summarized as follows:
1. Drug factors. Drugs are the most common cause of urticaria.
2. Food. Certain foods, especially high-protein foods, are more likely to cause urticaria. Such as animal protein, plants, food additives, etc.
3. Infectious factors. Infections caused by various reasons may cause urticaria. In particular, infection by parasites or protozoa is an important reason why some chronic urticaria will not heal for a long time.
Fourth, other causes of urticaria include inhaled substances, such as animal fur, pollen, fungal spores, etc. Physical or chemical factors such as cold, heat, light, pressure stimulation. Diseases of the nervous and endocrine systems.
When the seasons change, do four things to control urticaria to prevent recurrence
1. Antihistamines
Urticaria can be treated with antihistamines Treat with amines. This drug can effectively reduce the symptoms of skin itching and inhibit the occurrence of wheals, which will be helpful to improve the condition. However, antihistamines have serious side effects, so you need to consult a doctor before taking them and follow the doctor's instructions.
2. Block allergens
First of all, you should find out the trigger of the disease as much as possible and remove it. Current medical science believes that urticaria has not yet been cured, and both adults and children should be mentally prepared to deal with urticaria. Avoid contact with allergens, and prohibit or fast certain drugs or foods that are allergic to the body. Food elimination method: Generally, 3-4 days after the onset of the disease, if the skin lesions are reduced or subsided, recall the food eaten before the rash is different from the food eaten in the past 3-4 days. If you find suspicious food but cannot be sure, After the rash has completely subsided, use a provocation test to rule it out. For those patients who are prone to relapse after hot and cold stimulation, they should not avoid it too much. Instead, they should be exposed gradually and adapt by gradually extending the time of hot and cold stimulation. For allergies caused by their own lesions, pediatric patients should actively treat the original disease to eliminate allergens.
3. Improve allergic constitution:
Due to the stimulation of allergens, the immune function of the human body is disordered, causing an abnormal increase in immunoglobulin E in the body. Repeated exposure to allergens causes a large amount of IgE to be produced in the body. Antibodies attach to immune cells for a long time, causing the secretion of histamine and other inflammatory mediators to harm the body's immune response. From the immunological point of view of urticaria, the fundamental treatment of urticaria should control IgE and regulate the balance of immunoglobulins. Mainly, the current treatment of urticaria mostly stays at the inflammatory stage such as antihistamines. Some people will try to treat it by improving immunity. However, allergies are not caused by low immunity. The imbalance of the body's five immune globulin secretions is the disease. The fundamental cause of IgE antibodies in the current international immunology research is to supplement a large amount of Xinminkang probiotics to reduce the IgE antibodies in the body, and regulate the balance of immunoglobulins by stimulating the secretion of interferons, so as to solve the problem of IgE anti-human antibodies that cause urticaria. The body's immune response is restored correctly. The effective combination of anti-allergic drugs and Xinminkang probiotics can also produce ideal recovery results.
4. Patients with urticaria need to stay away from foods with relatively high protein content and foods with a lot of food additives
The causes of urticaria are very complicated, and the common causes may be related to food. related. Among various foods, those with higher allergenicity include foods high in protein. Such as eggs and milk. If you have experienced discomfort after eating them before, you should eat less during the allergic period
Such as desserts, snacks, biscuits, puffed foods, etc. These foods not only have many food additives, but also It contains a large amount of fat, sugar, salt and other ingredients, which are risk factors for inducing hyperlipidemia, hypertension, diabetes, gout, heart disease and other chronic diseases and metabolic syndrome diseases. For patients with urticaria, they should also try not to eat to avoid urticaria caused by food additives.
