Urticaria: symptoms, type, treatment
According to statistics, people have about 20% chance of getting urticaria in their lifetime. It may occur at any age. The incidence of women is 2 to 3 times that of men. It is a fairly common skin disease, especially the stress of modern life. Large, patients have more and more trends.
I often hear that urticaria is caused by eating seafood. What is the relationship with stress?
Common misunderstanding of urticaria
Urticaria is not necessarily caused by food. As long as it can cause the release of histamine in the body, food, clothing, and transportation, it may cause symptoms.
Factors that may induce urticaria include:
- dust mite
- Mango, kiwi
- Organic solvents
- Oral or topical medication
- other factors
The main symptoms of urticaria
There are three main types of common symptoms, and the symptoms and range of symptoms will depend on the severity.
- Inflammation: Pityriasis may occur throughout the skin, depending on the severity.
- Itching: The rash usually has an itchy sensation, especially at night.
- Angioedema: It is prone to swelling in areas where the skin is thin, such as the eyes, lips, and so on.
Pathogenic mechanism of urticaria
Many allergens such as seafood, dust mites, etc., when they first come into contact with the human body, the body will initiate a defense mechanism to activate B cells in the body, which in turn triggers the mass production of E-type immunoglobulin (IgE).
Once the human body is exposed to the allergen again, the E-type immunoglobulin will bind to it. Under the stimulation, the mast cells in the skin will release histamine, causing the blood vessels in the skin to swell and the nerves to cause itching.
The difference between acute urticaria and chronic urticaria
Many people are not easy to distinguish between acute and chronic urticaria. In fact, the biggest difference between the two is that chronic measles usually recurs for more than six weeks for unknown reasons, and acute urticaria will only attack when exposed to allergies, and will not last until Six weeks.
In general, acute measles is caused by diet. As soon as the cause is found and avoiding contact with allergens, it usually improves soon.
Once the symptoms persist and repeat for more than six weeks, it is called “chronic urticaria”. These patients are usually not caused by food, but related to personal physique. Others such as mental or emotional ups and downs, life pressure may be The cause of the induction, because the cause of chronic urticaria is difficult to diagnose, it is also difficult to prevent in advance, so the symptoms of redness and itching are easy to appear repeatedly.
|Chronic urticaria||Acute urticaria|
|Attack time||> 6 weeks||< 6 weeks, short 2~3 days|
|Pathogenic factor||Stress, physical fitness, it is difficult to find the cause||Common in diet|
|medical treatement||Long-term medication control||Short-term or no need|
Type of chronic urticaria
The symptoms of long-term redness and itching make many patients uncomfortable. Because there are countless factors that cause chronic urticaria, there are many different types of medicine. The most common type is “chronic urticaria”, which accounts for about 60%. %; followed by physical measles, accounting for about 35%; the last is vasculitic urticaria, accounting for about 5%.
What are the treatment strategies for acute and chronic urticaria?
In the first step of treatment, both must find out the cause, avoid the induced factors in life, and then adopt different treatment methods according to acute and chronic.
Acute urticaria can be cured without treatment. When itching is difficult, it can be relieved by ice or pat. If the situation is serious, the doctor may take anti-histamine treatment orally or by taking it once a day.
The first line of treatment for chronic urticaria is the second-generation antihistamine, which is administered daily. If the treatment is not effective, the physician will increase the dose by two to four times, or consider other alternative medicines, use immunosuppressants (such as steroids). If the itchy skin is more serious, ask your doctor to open an antipruritic ointment to improve your symptoms.
As long as you keep in mind the following life strategies and treatment principles, you can get good control of chronic measles.
- Keep away from allergens
- relieve stress
- Avoid scratching
- Improve awareness of disease
- Regular treatment, long-term follow-up
- Do not reduce or stop treatment
More than 50% of chronic urticaria is related to stress
Chronic urticaria is a kind of “physical and mental skin disease”. According to long-term observation by clinicians, most patients with chronic urticaria are unable to get rid of the stress of life, especially before the onset of stress index.
Physicians suggest that physical and mental adjustment is important for improving chronic urticaria. Many patients can improve their condition by changing their pace of life, adjusting their work schedules, and arranging leisure activities to relieve stress.
