The symptoms of urticaria are easily ignored by people. Generally speaking, those who recover within a short period of time are called acute urticaria.

Six symptoms of urticaria
1. Acute urticaria
Acute urticaria often starts quickly, with the skin suddenly itching and appearing quickly. Different bright red wheals, round, oval or irregular in shape, mostly isolated and scattered, but can also be merged into sheets. However, if serum leaks out rapidly in the capillaries and compresses the tube wall, the wheal may appear pale and the pores on the surface may appear as orange peel-like. Within a few hours, the edema reduced, and the wheals turned into erythema and gradually disappeared, but new wheals occurred one after another.
2. Chronic urticaria
The systemic symptoms of chronic urticaria are generally mild, with wheals that are more or less frequent and occur repeatedly, often for months or years. Some are time-dependent, such as getting worse in the morning or before going to bed, while others are irregular. In most patients, no cause can be found.
3. Artificial urticaria.
After scratching the skin with hands or scratching the skin with a blunt instrument, strip-like bulges will appear along the scratches, accompanied by itching, which will subside soon.
4. Cold urticaria
Can be divided into two types: one is familial, autosomal dominant, and relatively rare. Onset occurs shortly after birth or early in life and recurs. In addition to wheals after encountering cold, symptoms such as fever, chills, headache, and joint pain may also occur. The other type is acquired, which is more common in young women. After the temperature drops suddenly and comes into contact with cold wind, cold water or cold objects, wheals or patchy edema will occur in the parts exposed or exposed to cold objects, which lasts for half an hour or even 3 to 4 days. Hour.
5. Cholinergic urticaria
It is small papular urticaria. It is more common in young people. It occurs due to factors such as exercise, heat, emotional stress, eating hot drinks or alcoholic beverages, which prompt acetylcholine to act on mast cells. The wheal appears a few minutes after being stimulated, with a diameter of about 2 to 3 mm, and is surrounded by a large red halo. It is often distributed on the upper part of the trunk and upper limbs and does not merge with each other. It subsides within half an hour to an hour. Feeling itchy. Sometimes there is only severe itching but no rash.

1. Exercise
Strengthening exercise is an effective way to prevent and relieve urticaria. You can do it through jogging or some simple exercises. Physical activity methods to relieve. Many exercises can relieve urticaria, such as swimming, badminton, Tai Chi, etc.
2. Regulation of intestinal immunity
The most studied pathogenesis of urticaria is the autoimmune theory, and the onset of urticaria has attracted more and more attention in clinical trial research. In this regard, Dr. Xie Peishan, R&D Director of the Taiwan Research Center and the Institute of Food and Applied Biotechnology of National Taiwan University, found that about 2/3 of chronic urticaria is related to autoimmunity. The disorder of immune function leads to the extreme reduction of histamine release from mast cells. , may release histamine-releasing factors, which will make them more sensitive to endogenous substances and release histamine; when the immune process is exempted, the histamine release limit of the mast cells returns to normal, and the urticarial wheals may disappear.
Supplementing Xinminkang anti-allergic probiotics can improve allergic constitution and regulate immune allergies. Xinminkang's anti-allergic probiotics regulate the balance of immunoglobulins by stimulating the secretion of cellular interferon (IFN-r), thereby restoring the body's immune response to the correct state. Xinminkang's anti-allergic probiotic immunotherapy has a significant effect on urticaria caused by food, pollen, cold and heat, and other stimuli. Xinminkang anti-allergic probiotics contain 6 patented anti-allergic strains, which can bring intestinal microorganisms to an ecological balance, thereby promoting the secretion of interferons and regulating the balance of immune cell activity.
Anti-allergic probiotics are based on improving the physical constitution of urticaria patients, thereby avoiding the confusion that drugs can only relieve symptoms but cannot adjust allergic constitution.
3. Avoid spicy, cold, and spicy foods
As the saying goes, "Disease comes from the mouth." In addition to seasonal changes, the onset of urticaria is also related to diet. Certain foods may be Causes of the disease include fish, shrimp, seafood, canned foods, pickled foods, and beverages containing artificial colorings, preservatives, yeast and other artificial additives.
