Eczema, or atopic dermatitis, is an itchy type of skin rash. Eczema usually occurs on the hands and on the bent (back) surface of the knees but can occur anywhere on the skin. It tends to flare up and then disappear for no apparent reason. In the acute form, eczema causes inflammation, redness, dryness, and itching of the skin. Some of the skin lesions can peel and ooze. If eczema becomes a chronic problem, in addition to the itching that remains, dry scales develop on the skin and can thicken and change its texture and color. Most acute cases are caused by an allergic reaction. Patients may be allergic to certain foods or other substances. In any case, it is very likely to cause a reaction either from the consumption of the allergen or even just by contact with it.
Chronic eczema is a complex condition that usually includes a family history of eczema, asthma or allergic rhinitis, difficulty managing stress, or food intolerance. It has also been linked to immune system disorders, candidiasis as well as low levels of fatty acids, and other micronutrient deficiencies.
