Understanding Eczema - the Basics
What Is Eczema?
Eczema is a skin condition caused by inflammation. Atopic dermatitis is the most common of the many types of eczema. While the word "dermatitis" means inflammation of the skin, "atopic" refers to an allergic tendency, which is often inherited. These eczema sufferers have a higher risk of developing other allergic conditions (like asthma or hay fever).
Typically, eczema causes skin to become itchy, red, and dry -- even cracked and leathery. Eczema most frequently appears on the face and extremities, but it can show up in other areas, too.
Eczema is a chronic problem for many people. It is most common among infants, many of whom outgrow it before school age.
What Causes Eczema?
Like asthma, eczema seems to run in families. Certain genes make some people have extra-sensitive skin, and certain environmental factors -- like stress -- can trigger an episode of eczema.
Eczema is also caused or worsened by contact with irritants in common substances such as:
- woolen and synthetic fabrics
- soap and other agents that dry skin
- heat and sweat
Eczema can also be worsened by dry skin.
Since eczema may in part be an internal response to stress, any emotionally charged event -- from a move to a new job -- may trigger a flare-up.
