Symptoms of eczema

Causes of eczema
The reasons of many eczemas remain uncertain or sometimes they are probably produced by a combination of different factors.
This is the case of seborrhea (seborrheic dermatitis) which is attributed to a combination of environmental, genetic, hormonal, and immune-system factors.
Some other reasons that can produce or trigger eczema are:
– Allergies: Allergy to certain substances, either by contact or ingestion, can cause skin reactions. This is the reason for one of the most frequent types of eczema, called contact dermatitis. For example, some people react negatively when their skin gets into contact with some plants, such as ivy.
Allergic reasons are also at the base of atopic eczema, also called atopic dermatitis. In this case, this type of anomaly has a genetic reason but it is aggravated when the patient gets into contact with an allergen. It generally occurs together with other diseases, such as asthma, hay fever or conjunctivitis.
– Inadequate diet (too many animal fats, alcoholic beverages, pastries, chocolate, gluten etc.). For example, Duhring’s disease, also called dermatitis herpetiformis, seems to be connected with gluten intolerance, producing itching pustules in several parts of the body such as elbows, knees, buttocks, etc.
– Poor blood circulation: Sometimes skin shows the symptoms of a poor blood flow by means of similar symptoms to eczema. This is the case of congestion eczema, also called varicose eczema, that generally appears in the ankles which become red or darkened. It is related with poor blood circulation in the legs, so it occurs together with varicose veins. Ulcers can appear in the legs very frequently.
– Infections: Some infections produced by different organisms (virus, parasites, bacteria) can bring forth different types of eczematous reactions.
– Environmental conditions: Excessive heat, along with the use of certain tight clothes may be the cause of eczema or skin rashes. A too dry atmosphere is also the main reason for the appearance of xerotic eczema, a type of condition characterized by the formation of dry patches in the skin that appears very dry and scaly. It is very common in winter.
On the contrary, warm weather can be a factor triggering dyshidrotic eczema, that can produce many itching pruriginous blisters on hands or feet.
– Rubbing and scratching: Sometimes eczemas are a consequence of some clothes constantly rubbing against the skin. Similarly results can be obtained by the continuous scratching. This aggressions to the skin are responsible for several types of neurodermatitis, such as lichen simplex chronicus (LSC) that produces thicker and more leathery brown patches in the part of the skin subjected to continuous rubbing or scratching.
– Stress: Although not directly responsible, stress may aggravate many types of eczema.
