Acute urticaria, to such as lightning, within hours, the skin can be covered with the expiration of the wind group, and accompanied by bursts of itching. As a host of reasons may cause urticaria, allergic constitution which is the absolute "top priority", when the Spring Festival every year, there is always a large number of allergic people, because of the difficulty to resist food temptations, bites after being patronized acute urticaria , scared out of cold sweat.
Although acute urticaria comes and goes in too fast, but after treatment is not convenient. New Year, friends and relatives who can not help but disrupt the mood, how to face the full table of delicacies, both real treat, but also to avoid urticaria "attack"?
Acute urticaria allergic constitution favorite
Acute hives diet and daily life are inseparable, eating properly can cause many diseases, acute hives is one of them. Acute hives, commonly known as "acute urticaria", is caused by a variety of pathogenic factors, the most common allergic by specific physical and food allergy.
The so-called specific allergic constitution refers to the type of serum which there is a high content of specific proteins - IgE immunoglobulin, its content several times to several ten times higher than normal, these are the genes determined the existence of such immune globulin is seeking patients with acute measles internal pathogenic factor. However, the occurrence of acute hives, there must be the role of external pathogenic factors, the most common external pathogenic factor is caused by some food allergies.
Under normal circumstances, food protein into the gastrointestinal tract, in a variety of digestive enzymes, for example, pepsin, trypsin and other protein digestive enzymes, through a series of hydrolysis reactions, the food will be large and complex protein molecules into small, hydrolysis simple amino acids and small peptides. Food proteins are hydrolyzed into amino acids and small peptides, the body will occur after the absorption of nutrition effect; food proteins are hydrolyzed into amino acids and small peptides, and has lost its antigenicity, that is, lost the possibility of allergic reactions.
The table is so delicious triggered urticaria
Many common foods can make some people allergic reactions and trigger acute hives. Allergic constitution with specific people, acute food-induced hives usually caused by the following two cases.
One is directly to the protein contained in the food caused allergic reactions. This process is this: certain food proteins enter the body, the body will induce specific IgE in patients with a large number of immunoglobulin production, resulting antigen-antibody immune complexes, leading to the body produces a large number of histamine, bradykinin and other bioactive substances, The biological activity of substances make the skin, gastrointestinal telangiectasia, vascular extravasation of serum that suffered skin edema, caused the formation of the wind group acute hives, also lead to gastrointestinal smooth muscle disorder associated with paroxysmal abdominal pain.
In other cases, the patient digestion of food protein in the body formed during the intermediate - peptone caused by allergies occur, the specific process is as follows: patients with a short time a large number of animal protein ingestion of food, or both heavy drinking, These conditions can make the body's ability to digest food greatly reduced, the result can only be broken down into the middle of food protein digestion product - peptone, can not continue down into amino acids and small molecule peptide, peptone absorbed through the intestinal mucosa, but also the formation of antigen antibody immune complexes, also can cause the body produces a large number of histamine, bradykinin and other bioactive substances, may cause acute hives and abdominal pain.
According to the consumption and the occurrence of acute hives interval length, food allergy can be divided into acute hives hair and delayed two-speed, speed hair mostly occurred two hours after eating, delayed a day or several days for the eating place.
Different types of food, its intensity is different antigen, that is, the strength of different allergic. In general, the following are highly allergic to some food proteins: one is the crab, shrimp, clams, meat, wool clam, snail (including snail, conch) and other shellfish, fish, other pork, beef, mutton, dog meat aquatic products such as meat and fish, as well as milk, goat milk and other dairy products,
Eggs, duck eggs, goose eggs in the egg white, walnut, walnuts, gingko nuts and other foods, peanuts, soy, lentils and other legumes, and mushrooms, shiitake mushrooms and other fungi food.
Be prepared for how to find their own food allergens
Of course, the patient could not have taken place above all food allergies, usually only one or several food allergies and trigger acute hives, patients can practice and explore in the diet are allergic to their food. So, how can we find out what the food allergy?
First: pay attention to eating and the occurrence of acute hives relationship between the time interval;
Second: to use food exclusion. The specific exclusion of food is this: first of all be patient ate some food for 3 weeks the following: rice, vegetables, carrots, potatoes, pumpkin, canola oil, sugar, salt, all kinds of tea leaves. Then a kind of the easy to eat each day of food allergy, food for several days after the observation, whether acute hives, if the cause of acute hives, indicating the increase of patients may be the place of food allergies, these foods should promptly indigestion .
Third: To avoid the occurrence of acute hives, but also careful not to eat within a short time a large number of animal protein foods, eating when not drinking heavily.
Upon the occurrence of food allergy-induced acute hives in the clinical treatment is the injection of ACTH and anti-histamine drugs, such as dexamethasone injection combined with chlorpheniramine injection, it can only temporarily alleviate the acute treatment and find the symptoms of measles, but can not stop repeated attacks of acute hives.
