Eczema is considered as a chronic, recurrent skin condition that usually occurs during infancy and early childhood but can persist up to adulthood. Just like with other allergies and asthma, atopic dermatitis typically run in families.
Always bear in mind that atopic dermatitis is not a rash that causes itchiness. It is described as an itch that turns to a rash once scratched. In case the itchiness can be managed and there is no scratching involved, rash or eczema will not manifest.
This skin condition is quite common during childhood usually before 5 years old. Adults are not often affected but can start at any age. Essentially, once eczema develops in infants, it is quite severe but most cases tend to resolve in later childhood. Children with this skin condition are more likely to have other allergic diseases including asthma and allergic rhinitis.
Diagnosing eczema
The diagnosis of eczema is made though the history of symptoms and physical examination by the doctor.
The individual should be considered atopic or has a family history of allergic diseases. There are rare cases in which an individual has the condition without being atopic.
Pruritus or itching is usually present so that rash can occur. In case the skin or areas of rash do not itch or were not scratched, the individual does not have eczema.
When it comes to eczema, it refers to the appearance of rash among individuals with atopic dermatitis and occurs in other skin conditions as well. The rash appears red in color with small-sized blisters or bumps present. These can flake or ooze with further scratching. After some time, the skin appears leathery and thick.
Where does eczema typically develop?
The location of eczema typically depends on the area that was scratched. Among infants and young children, the rash typically develops on the face, trunk as well as chest, back of the scalp and even the legs and arms. This simply shows areas where the child was able to scratch excluding the diaper area.
Among older children and adults, the location involves the skin behind the knees and front of the elbows. It can also develop on the face and limited to the soles of the feet and palms of the hands.
Potential for itching
The itchiness can be triggered by infections, irritants, stress and allergies. These can cause itching via direct stimulation of the skin including chemicals, harsh soaps, heat, as well as wool fabrics and sweating. By avoiding these irritants through the use of cotton clothing, gentle soaps and staying dry and cool, itching can be prevented.
Remember that those who have eczema are at risk for skin infections due to viruses, bacteria and fungus. In addition, allergies are also triggers for itchiness among those who have the skin condition. The usual allergens include animal dander, sun exposure and dust mites.
