Urticaria (wheals) is an immune system disease.

Urticaria, commonly known as "wheals", is a rapid-onset, slightly raised, flaky skin allergic change caused by increased permeability of skin capillaries and infiltration of serum into tissue gaps, which leads to local skin edema. Its characteristics are sudden occurrence and rapid disappearance, which usually disappears within 24 hours and is often accompanied by unbearable itching. Urticaria is common in urticaria and angioedema caused by various foreign protein foods (animal or plant) or drugs.

Wheal is a localized, temporary, edematous, flat protrusion that develops rapidly and disappears quickly. It appears suddenly, disappears quickly, and leaves no trace when it disappears. The number of wheals can be large or small, the sizes can vary, the shapes can be irregular, and the color can be light red or pale. When it occurs in loose tissues such as the eyelids, lips, and vulva, the local swelling is obvious and the boundaries are unclear. It is the main manifestation of urticaria.

Common causes of urticaria include: ① Foods such as fish, shrimp, crab and eggs are the most common. Secondly, certain spices and condiments can also cause it. ② Many drugs can cause this disease. Penicillin, sulfonamides, furazolidone, serum vaccines, etc. often cause urticaria through immune mechanisms. Drugs such as aspirin, morphine, atropine, and vitamin B1 are histamine releasers that can directly cause mast cells to release histamine and trigger urticaria. ③Infection: including viruses (such as influenza virus, hepatitis virus), bacteria (such as Staphylococcus aureus), fungi and parasites (such as roundworms, etc.). ④Animal and plant factors, such as insect bites or inhalation of pollen, feathers, dandruff, etc. ⑤ Physical factors, such as cold, heat, sunlight, friction and pressure can cause it. In addition, gastrointestinal diseases, metabolic disorders, endocrine disorders and mental factors can also cause it.

In addition, some special urticaria has little to do with the above-mentioned daily allergens. For example, some people will develop urticaria when exercising, sweating, being in a high temperature environment, being emotionally stressed, or taking a hot bath. This type of urticaria is called "choleretic urticaria"; and "dermatographism" is that the areas where scratches or scratches will swell and produce urticaria. Cold, heat, sunlight, and local skin pressure can also cause urticaria in people with certain specific constitutions.
