特应性皮炎

Atopic dermatitis, often referred to as eczema, is a chronic (long-lasting) disease that causes inflammation, redness, and irritation of the skin. It is a common condition that usually begins in childhood; however, anyone can get the disease at any age. Atopic dermatitis is not contagious, so it cannot be spread from person to person. Atopic dermatitis causes the skin to become extremely itchy. Scratching leads to further redness, swelling, cracking, “weeping” clear fluid, crusting, and scaling. In most cases, there are periods of time when the disease is worse, called flares, followed by periods when the skin improves or clears up entirely, called remissions. Researchers do not know what causes atopic dermatitis, but they do know that genes, the immune system, and the environment play a role in the disease. Depending on the severity and location of the symptoms, living with atopic dermatitis can be hard. Treatment can help control symptoms. For many people, atopic dermatitis improves by adulthood, but for some, it can be a lifelong illness.
