ECZEMA
What causes eczema?
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. . In atopy there is an excessive reaction by the
immune system producing inflamed, irritated and sore skin.
Associated atopic conditions include asthma and hayfever.
Other types of eczema are caused by irritants such as chemicals
and detergents, allergens such as nickel, and yeast growths.
What are the different types of eczema?
Atopic eczema
Atopic eczema is the commonest form of eczema and is closely
linked with asthma and hayfever. It can affect both children
and adults, usually running in families. One of the most
common symptoms of atopic eczema is its itchiness (or pruritis),
which can be almost unbearable. Other symptoms include overall
dryness of the skin, redness and inflammation. Constant
scratching can also cause the skin to split, leaving it
prone to infection. In infected eczema the skin may crack
and weep (‘wet’ eczema).
Allergic contact dermatitis
Develops when the body’s immune system reacts against
a substance in contact with the skin. The allergic reaction
often develops over a period of time through repeated contact
with the substance. In order to prevent repeated reactions
it is best to prevent contact with anything that you know
causes a rash.
Irritant contact dermatitis
This is a type of eczema caused by frequent contact with
everyday substances, such as detergents and chemicals, which
are irritating to the skin. It most commonly occurs on the
hands of adults and can be prevented by avoiding the irritants
and keeping the skin moisturised.
Infantile seborrhoeic eczema
A common condition affecting babies under one year old,
the exact cause of which is unknown. Also referred to as
cradle cap, it usually starts on the scalp or the nappy
area and quickly spreads. Although this type of eczema looks
unpleasant, it is not sore or itchy and does not cause the
baby to feel uncomfortable or unwell. Normally this type
of eczema will clear in just a few months, though the use
of moisturising creams and bath oils can help to speed this
along.
Adult seborrhoeic eczema
Characteristically affects adults between the ages of 20
and 40. It is usually seen on the scalp as mild dandruff,
but can spread to the face, ears and chest. The skin becomes
red, inflamed and starts to flake. The condition is believed
to be caused by a yeast growth
