Is the eczematous itch becoming a hitch?

Eczema - Causes

Several factors are responsible for causing eczema (dermatitis/skin allergy); however, the exact origin and mechanism of the conditions are still not clear. Several studies have suggested many factors, including genetic as well as environmental factors, that are responsible for triggering eczema.

In most cases, people may show abnormal function in their immune system, where their body responds abnormally to external allergens, which does not harm people with a good immune system.

Some of the causes of eczema include the following:

  • environmental allergens: house dust, sand, pollen, smoke, moulds, animal dander, etc.;.
  • dietary allergens: milk and milk products, fish, soy, eggs, peanuts, etc.;
  • contact with irritant substances such as soaps, cleaning products, detergents, cosmetics, perfumes, certain forms of clothing, rubber, jewellery, watches, metals such as nickel, etc.;
  • genetic factor – an important cause in the development of eczema. Patients with eczema have commonly reported a family history of allergies, asthma, hay fever or other forms of allergic diseases;
  • psychological stress, a major cause in several patients; however, its correlation with triggering altered immune response remains unclear;
  • alteration in temperature and humidity;
  • dry climate and very cold temperature;
  • abnormal blood circulation, especially in the legs, that further causes stasis dermatitis; and
  • unknown factors that trigger certain forms of dermatitis, such as seborrhoeic dermatitis, atopic dermatitis, etc.
