urticaria is called rubella. It is an edema reaction caused by the expansion and permeability of small blood vessels in the skin or mucous membrane. It has limitations and most patients have symptoms that will subside within 1 day. But the more troublesome thing is that after subside, new rashes will appear repeatedly. The course of the disease can be as short as several days and as long as several months. The etiology of urticaria is more complicated, and most patients cannot find the cause, which is a difficult problem in treatment.
To cure urticaria, in addition to the strong autoimmune function of the patient, the most important thing is to find out the cause and prescribe the right medicine. Generally speaking, the common causes of urticaria include food irritation, infection, drug side effects, environmental influences, insect bites, autoimmune factors, genetic factors, etc.
1. The main clinical symptoms of urticaria
1. The most obvious symptom is that the skin is damaged by wind masses, which are different in shape and have no regular pattern. Finally, the wind masses will become one piece. The wind mass may disappear after a few minutes, but it may disappear after a few days without leaving a trace.
2, the skin of the affected area is itchy, the skin is pale or bright red, and a few patients may have erythema.
3. Some patients will have symptoms such as nausea and vomiting, head pain, abdominal pain, and diarrhea. In severe cases, chest tightness, pale complexion, rapid heart rate, and sudden drop in blood pressure will also occur.
4 is divided into two types: acute urticaria and chronic urticaria. The former can be cured in a short period of time, while the latter will be recurrent and the course lasts at least 6 weeks or more.
2. Treatment of urticaria
1. Although the etiology of urticaria is complicated, it is necessary to find the cause of the disease in order to be completely cured. If it is caused by an infection, the infected foci must be treated. People who cause drugs should stop allergic drugs, and they should avoid eating the food if they are allergic to certain foods. Secondly, we must avoid predisposing factors, such as cold urticaria to keep warm, contact urticaria to avoid contact with allergens and so on.
2. The drugs used to treat urticaria mainly include antihistamines, glucocorticoids, immunosuppressants, and drugs that inhibit the degranulation of mast cells and reduce the release of histamine. Antihistamine drugs have good effects in the treatment of various types of urticaria, and the side effects are small, so they are used more. Glucocorticoids are generally used when antihistamines are ineffective, and long-term use should be avoided. When patients with chronic urticaria have repeated illnesses and general treatment is ineffective, immunosuppressive agents can be used. However, immunosuppressive agents have greater side effects, so they are less used.
During the acute onset of urticaria, if the location of the lesion occurs in the larynx, bronchus and other mucosal parts, it will most likely cause breathing difficulties and even suffocation. If it is not treated in time, it can be life-threatening and needs to be paid attention to, and to actively and correctly deal with the disease of urticaria, remember not to be careless. However, as long as the disease is treated in a timely manner, the cause is identified, the treatment method is correct, the cure is not difficult, and there is no need to worry too much.
