Eczema Eczema is a general term used for describing various types of skin inflammation - dermatitis. Although its cause is not completely known, it is supposed to be an abnormal response of the bodys immune system to the influence of the external factors, sometimes aggravated by stress and anxiety. The condition is often irritated by sweating, exposure to extremes of temperature (heat, cold), and abnormal condition of the skin (excessively oily or dry skin). Eczema can occur at any age but is most common in infants to young adults, it can affect any part of the body; however, in infants, it is often localized to the forehead, cheeks, forearms, legs, scalp, and neck. In children and adults, eczema typically covers the face, skin and linings of the nose, neck, and the insides of the elbows, knees, and ankles. In later years may appear varicose eczema that is caused by blood circulatory problems in the legs. It is characterized by reddened, flaky skin, sometimes cracked or covered with tiny blisters; it can be either widespread, or limited to a few areas. In this condition the skin is extremely itchy, but scratching and rubbing are further damaging the skin and exacerbating the problem. In some cases excessive scratching causes the skin to thicken and its texture becomes leathery. Eczema is not contagious and for the moment cannot be utterly cured. Nevertheless, the symptoms of the condition may be managed well with treatment and avoidance of causative agents (triggers). Allergy-related conditions: atopic eczema is the most common type of eczema, that is supposed to be caused by general allergic reactions. This skin condition is provoked by allergens in the environment which are harmless to others, as opposed to contact with an irritant. Atopic eczema is a condition that is extremely itchy, sometimes even unbearable, accompanied with overall dryness of the skin, redness and inflammation. Atopic eczema is thought to be a hereditary condition. It commonly appears in people who suffer from related allergic conditions as well (asthma, hay fever); allergy contact dermatitis; irritant contact dermatitis. Non allergy-related conditions: infantile seborrhoeic eczema (cradle cap) typically starts on the scalp or the nappy area and quickly spreads. This type of eczema doesn't itch, doesnt cause the baby to feel uncomfortable or unwell and eventually goes away on its own in just a few months; adult seborrhoeic eczema typically affects 20 to 40 year old adults, covering the scalp, face, and upper body; varicose eczema may appear later in life, as a result of poor blood circulation in the lower legs; discoid eczema appears and disappears suddenly by its own, is characterized by small distinctive coin-shaped itchy red spots of severe dermatitis that may affect any part of the body, but typically develop on the legs and buttocks. It seems to appear more frequently in cold seasons when the skin is getting dry.
