What causes eczema or dermatitis?
The causes of eczema are many and varied, and depend on the particular type of eczema that a person has. Atopic eczema is thought to be a hereditary condition, being genetically linked. It is proposed that people with atopic eczema are sensitive to allergens in the environment which are harmless to others. In Atopy there is an excessive reaction by the immune system producing inflamed, irritated and sore skin. Associated atopic conditions include asthma and hay fever. Other types of eczema are caused by irritants such as chemicals and detergents, allergens such as nickel, and yeast growths. In later years eczema can be caused by a blood circulatory problems in the legs. The causes of certain types of eczema remain to be explained, though links with environmental factors and stress are being explored.
