Chronic urticaria refers to temporary inflammatory congestion and intravascular edema of the skin, mucous membranes, and blood vessels caused by various factors, and the duration of the disease is more than 6 weeks is called chronic urticaria, the cause of which is often uncertain. The clinical manifestations of urticaria are the irregular occurrence of wind clusters and plaques on the trunk, face or extremities. Episodes vary from several times a day to once every few days. The etiology of chronic urticaria is complex, and about 70% of patients cannot find a cause. Recent studies have identified food and inhalation allergies as the main causes of chronic urticaria. Allergen testing can be used as a screening indicator, and desensitization to allergens can be used as a treatment. However, because of the lengthy process of desensitization, time, energy and financial constraints, only a small percentage of patients undergo desensitization. In addition, because of the proliferation of food additives, it is difficult to determine exactly what the food becomes, so complete avoidance of allergic foods is almost impossible. In addition, chronic urticaria is related to immune and psychological factors, and is not simply a matter of allergy. Therefore, allergen testing can be used as a screening indicator, and it is not necessary to test all patients to avoid unnecessary medical expenses. In some patients, the allergen test is completely normal, but the hives still persist, which requires the joint efforts of the doctor and the patient according to individual differences. Medication for urticaria: The root of urticaria treatment is to remove the cause and triggering factors, but because the cause of the disease is complex, it is sometimes difficult to determine the causative factors, so medication is the key to this disease. 1, the treatment of light urticaria: for mild lesions, not accompanied by systemic symptoms, oral antihistamines and herbal treatment, common antihistamines are loratadine, cetirizine, epastine, fexofenadine, levocetirizine, desloratadine, etc. 2, heavy urticaria treatment: If the patient has systemic symptoms, such as shortness of breath, chest tightness and shortness of breath, abdominal pain, etc., it is time to seek medical attention. Can chronic urticaria be treated with hormones? Recurrent chronic urticaria makes patients suffer immensely and doctors often feel helpless to do anything about it. Even after applying several antihistamines and a combination of Chinese and Western medicines, the disease is still not under control or still recurs frequently, so if you apply hormones with a sense of luck, you may end up getting worse. Although the rash disappears within a short period of time, once the drug is stopped, the lesions flare up and lose their therapeutic effect on all antihistamines. Therefore, the use of hormonal drugs is strictly prohibited in the treatment of chronic urticaria. Can chronic urticaria be cured? All patients are concerned about the question, can chronic urticaria be cured or not? In my experience, it is very difficult to cure the disease, but it is possible to reduce the frequency and improve the symptoms of the disease. Some patients are able to control their recurrence within a short time after treatment, while others need a longer treatment course. But as long as the joint efforts of doctors and patients, change the diet, lifestyle, mood regulation and standardized drug treatment, chronic urticaria is very good treatment results. Several special groups of people with urticaria: 1, people with gastric disease: H. pylori and chronic urticaria are closely related, for some patients with gastric disease should be screened early for H. pylori, if found positive, early treatment. Most gastric patients with H. pylori will disappear after the hives are cured. 2, menopausal women: some menopausal women will appear transient urticaria, and treatment is very stubborn, this situation with the passage of menopause, the hives will disappear. 3, tumor patients: certain tumor patients repeatedly hives during treatment, on the one hand, due to tumor patients immune dysfunction, on the other hand, tumor patients take more kinds of drugs, when the tumor removed, the condition of hives will also disappear.
