Atopic Dermatitis


Service

Atopic dermatitis (AD), also known as atopic eczema, is a type of inflammation of the skin (dermatitis). It results in itchy, red, swollen, and cracked skin. Clear fluid may come from the affected areas, which often thicken over time. The condition typically starts in childhood with changing severity over the years.

In children under one year of age much of the body may be affected. As children get older, the back of the knees and front of the elbows are the most common areas affected. In adults the hands and feet are the most commonly affected areas.

Scratching worsens symptoms and affected people have an increased risk of skin infections. Many people with atopic dermatitis develop hay fever or asthma.

If one identical twin is affected, there is an 85% chance the other also has the condition.[3] Those who live in cities and dry climates are more commonly affected. Exposure to certain chemicals or frequent hand washing makes symptoms worse. While emotional stress may make the symptoms worse it is not a cause. The disorder is not contagious.
