Dry Hands May Be Sign of Eczema

 Dry hands that persist despite the use of lotions and
creams may be a sign of a condition called hand eczema.
Eczema is a term for different types of skin
inflammation (dermatitis). The
symptoms of eczema commonly include itchy, reddened, dry skin. Many things can cause
this type of skin irritation such as dryness, soaps and detergents, cleaning
products, rubber gloves and even cosmetic lotions and creams. Since the skin is
itchy, prolonged scratching often occurs which in turn leads to reddened,
irritated, scaling skin or to a leathery thickening of the skin (sometimes
called lichenification). Cracking and weeping of the skin may also
occur and open sores may become infected.
The causes of eczema have not been fully determined.
Allergies, stress, irritants, and genetic factors are all believed to be related
to the development of this condition. The tendency to have skin reactions like
this often runs in families. People with eczema involving their hands may also
have symptoms of asthma, food allergies, or hay fever.

What is eczema?
Eczema is a general term for many types of skin
inflammation, also known as dermatitis. The most common form of eczema is atopic
dermatitis (some people use
these two terms interchangeably). However, there are many different forms of
eczema.
Eczema can affect people of any age, although the
condition is most common in infants. Eczema will permanently resolve by age
3 in about half of affected infants. In others, the condition tends to recur
throughout life. People with
eczema often have a family history of the
condition or a family history of other allergic conditions, such as asthma or
hay fever. Up to 20% of children and 1%-2%
of adults are believed to have eczema.
What are the causes of eczema?
Doctors do not know the exact cause of eczema, but an
abnormal function of
the immune system is believed to be a factor. Some forms of eczema can be
triggered by substances that come in contact with the skin, such as soaps,
cosmetics, clothing, detergents, jewelry, or sweat. Environmental
allergens (substances that cause allergic reactions) may also cause outbreaks of
eczema. Changes in temperature or humidity, or even psychological stress, for some people lead to
outbreaks of eczema.
What are the symptoms of eczema?
Eczema most commonly causes dry, reddened skin that itches or burns, although
the appearance of eczema varies from person to person and varies according to
the specific type of eczema. Intense itching is generally the first symptom in
most people with eczema. Sometimes, eczema may lead to blisters and oozing
lesions, but eczema can also result in dry and scaly skin. Repeated scratching
may lead to thickened, crusty skin.
While any region of the body may be affected by eczema,
in children and adults, eczema typically occurs on the face, neck, and the insides of the
elbows, knees, and ankles. In infants, eczema typically occurs on the forehead,
cheeks, forearms, legs, scalp, and neck.
Eczema can sometimes occur as a brief reaction that only leads to symptoms for a few hours or days, but in other cases, the symptoms persist over a longer time and are referred to as chronic dermatitis.
