Eczema, also known as atopic dermatitis, is an allergic condition that affects the skin. The exact cause of eczema is not known, although it is activated by the immune system and is related to allergic reactions. Eczema can be triggered by just about anything coming in contact with the skin. Common triggers of eczema include soaps, detergents, weather (hot, cold, humid, or dry), environmental allergens, gloves, even emotional or mental stress. It occurs in atopic people, who are extra sensitive to skin irritation. Eczema causes intense itching and burning, and the skin appears dry, flaky and red. Repeated scratching of the rash can cause skin sores and cracks, which are susceptible to bacteria, even viral infection. These infections are usually very minor, but they do require treatment with antibiotics or they may become very severe.
