Urticaria is mostly caused by external or internal allergic factors, which are related to environmental factors such as diet and sweating allergy. The disease mostly occurs in summer, and it is easy to recur with different medical histories. Generally, the course of disease is more than 3 months, which is called chronic urticaria. Then, urticaria recurs, what should I do?
From the cause of the disease
The etiology of urticaria is very complicated, which is generally considered to be related to genetic and environmental factors.
Genetic and physiological factors
The cause of urticaria is related to people's physique and genetic factors, so even in the same environment, we will find that some people will get sick, and some people will not get sick, and the one who gets sick will generally not transmit urticaria to the other party. So this shows that different people have different defense abilities against urticaria because of their different constitutions and resistances. Some people's physique is sensitive, and it is easy to have adverse reactions to some factors in the environment, so the skin will become more prone to urticaria. Others are less prone to allergies and urticaria. Similarly, as far as heredity is concerned, if someone in the family often travels for urticaria, then the probability of future generations suffering from urticaria will be greater.
The influence of environmental factors
In modern society, there are many chemicals, food additives, environmental pollution and some dust that stimulate the skin and human body, and people also cause great damage to the environment. Similarly, when human beings destroy the environment and make new machines and chemical products, they also have a series of effects on their own bodies, the most direct of which is the stimulation to the skin. Skin irritation produces a series of reactions, such as redness and itching, which recur over time. This is chronic urticaria.
Judging from the performance of urticaria
First, accompanying symptoms: Urticaria occurs quickly and disappears quickly, and generally disappears by itself within 24 hours. Children are often accompanied by fever and gastrointestinal symptoms, and some are accompanied by localized edema of hands, feet, eyelids and even the whole face. Some may have skin abrasions. Rash on lips and eyelids, reddish complexion and unclear boundaries. This rash is the facial wind when wandering on the lips and face (called vascular edema in western medicine). If normal skin is scratched mechanically, scratching-like edema and swelling will appear in this part, which is called artificial urticaria or skin scratching.
Second, the size of skin lesions: rashes vary in size and shape, with bright red or reddish air masses, clear boundaries and severe itching, which will merge into large pieces after a long time.
Third, the duration: the rash often appears suddenly, and slowly fades after several minutes to several hours. Later, it appeared in batches, sometimes, sometimes, and the hair was nowhere to be found. After leaving no trace, it happens once or several times a day and stops in a week or so. Chronic patients have recurrent attacks for weeks, months or even years.
Therefore, once urticaria is found, it is necessary to treat and intervene as soon as possible, and the sooner you recover, the less painful it will be.
Immunologists have three ways to treat urticaria.
The first move is to find allergens.
Urticaria is mostly an allergic reaction caused by allergens entering the body. Finding out allergens and avoiding contact with allergens is the most effective way to prevent urticaria recurrence. If the allergen can be completely excreted, it can be recovered quickly. Therefore, those with mild allergic reaction can gradually recover after drinking plenty of water to promote allergen excretion, but if they are exposed to allergens again, they will get sick again, and their condition may be significantly worse than last time. At present, the technology of finding allergens is limited, and the best way is to develop the habit of keeping a diary to record the changes of food, drugs, substances and the surrounding environment that you contact every day. Once urticaria occurs, you can look for possible allergens according to the records. If you are exposed to the same substance twice, you are highly suspected of being allergic to it. Avoiding the second contact can reduce the recurrence.
The second measure, medication.
Urticaria is a systemic allergic reaction. Oral drugs are mainly used for anti-allergy. Commonly used drugs include antihistamines, calcium gluconate, and vitamin C. When acute urticaria's symptoms are severe, it needs to be used with hormone drugs. Please take specific medication under the guidance of a doctor. Don't abuse drugs by yourself, especially hormone drugs.
The third measure, immune antiallergic treatment.
Urticaria is actually an abnormal immune response of human body to harmless substances in the environment, not ordinary bacteria or viruses. In particular, these allergies belong to mucosal inflammation. It is scientifically proved that the IgE immunoglobulin in the immune system of patients with urticaria is 1- 10 times higher than that of normal people. These higher IgE will disturb the immune system of human body and make it allergic, which will lead to urticaria.
A large number of animal experiments and clinical experiments provide strong evidence that increasing the number of probiotics in digestive tract can prevent and even treat urticaria. The scientific proportion of six patented strains selected by Xinmin Kang's anti-allergic probiotics can improve the ecology of beneficial bacteria in the intestine, improve the wandering ability of protruding cells in the whole body, regulate the whole body immune function and relieve allergic symptoms; Xinminkang anti-allergic probiotics are composed of six strains, which can regulate TH 1 immune response, thus reducing excessive IgE-specific antibodies in the serum of urticaria patients, relieving allergic symptoms and adjusting allergic constitution. Compared with the simple drug treatment of urticaria, Xinminkang anti-allergic probiotics can produce good overall curative effect and effectively improve the quality of life of allergic patients. Compared with a single anti-allergic strain, the anti-allergic ability of immune regulation is more comprehensive.
What else should we pay attention to in life?
1, Don't scratch: Most people's intuitive response to skin itching is to scratch with their hands, but you may not know that this action can not only stop itching, but also make it itch more and more, mainly because when you scratch a local itch, it will raise the local temperature and release more histamine (allergen) in the blood, thus aggravating the condition.
2. Don't apply hot compress: Some people itch enough to use hot compress. Although heat can temporarily relieve the local area, it is actually another stimulus, because heat will make blood vessels tense and release more allergens. For example, some people like to soak in hot springs or bathtubs, or keep warm in thick quilts, which may cause urticaria.
3, pay attention to diet: the incidence of urticaria has a certain relationship with diet, and some foods may be the cause. For example, fish, shrimp, seafood, canned food containing artificial additives such as artificial pigments, preservatives and yeast, pickled food and beverages can all induce urticaria.
