Pathogenesis of urticaria

The pathogenesis of urticaria is an allergic disease in which various adverse factors lead to the activation of a variety of inflammatory cells and the release of inflammatory mediators, resulting in vasodilation and increased permeability of blood vessels, as well as hypersecretion of glands.

Urticaria is a benign disease that occurs in various parts of the skin and mucous membranes. Patients are affected by adverse factors such as irritants and allergens, which can lead to the activation of various inflammatory cells in the local skin and mucous membranes, and the release of a large amount of histamine, prostaglandins and other substances, causing telangiectasia and congestion in the affected parts., and interstitial fluid exudation, etc., leading to uncomfortable symptoms such as skin edema, skin erythema, and itching.

After the disease is diagnosed, patients should promptly intervene to prevent the allergic reaction from worsening and cause anaphylactic shock.
