Eczema
What is it?
Eczema, also known as atopic dermatitis (or inflammation of the skin), is a chronic skin condition commonly characterized by dry, red, swollen, patches of skin that itch relentlessly. For many individuals who have eczema, frequent scratching of the affected area only makes the condition more bothersome and uncomfortable. Repeated scratching also may cause the skin to become red or swollen, which can then cause the area to crack, ooze clear liquid, and become crusty. Eczema occurs most often in the folds of the elbows or behind the knees, but it can appear anywhere on the surface of the body. In children, eczema often occurs on the scalp and face as well. An eczema outbreak can last from a few days to a few weeks or more. And whereas some individuals experience a single outbreak, many experience frequent flare-ups, usually as a result of exposure to one or more triggers or irritants.
The itching and scratching caused by eczema can lead to breaks or cracks in the skin. Often, bacteria can infect the open skin wounds and cause an infection. These skin infections, also called cellulitis, can cause the skin to appear red and swollen and may be warm to the touch. These skin infections can spread to other areas of the body, therefore, it is important to contact a doctor if cellulitis is suspected.
There are eight types of eczema, usually distinguished by either cause or appearance. Learn more about the types of eczema by clicking on the links below.
