Causes and Symptoms
Eczema, more commonly known as dermatitis, is one such
skin condition. It is a skin disorder that is characterized
by dryness of the skin accompanied by one or more of the
following symptoms: itching, flaking, redness, blistering,
bleeding, or even oozing. Usually, it's just the itchiness
and the redness, with the bleeding usually a result of the
incessant scratching due to the itches. There might be
temporary skin discoloration (aside from the redness),
which can sometimes be the cause of lesions. Scarring,
however, is relatively uncommon.
The names eczema and dermatitis themselves are just
general terms that are used to describe the many types of
skin inflammation that share, more or less, some common
symptoms. The more common types of eczema are atopic
eczema, contact dermatitis, xerotic eczema, and seborrhoeic
dermatitis. Among the four, atopic eczema is the most
common and is usually the type most dermatitis sufferers
are afflicted with. Contact dermatitis, meanwhile, comes in
two types: allergic and irritant. Each is defined based on
the sources of their condition. For allergic contact
dermatitis, it's allergens, while irritant contact
dermatitis stems from direct contact with certain solvents.
Xerotic eczema comes from another skin condition, dry skin,
which becomes serious enough to turn into dermatitis.
Seborrhoeic eczema is dermatitis that affects the
sebum-gland rich parts of the skin and is usually
characterized by greasy scaling of the eyebrows and the
scalp.
Causes of eczema are generally not known, but in atopic
eczema, it is generally thought that a malfunction of the
body's immune system, coupled with dry, irritated skin, is
one of the probable reasons for the condition. Most times,
your dermatologist or doctor will first check on a number
of things to accurately diagnose or pinpoint the underlying
cause of your eczema. Information like family history,
dietary and lifestyle habits, and any history of allergic
reactions are all taken into account. There are also
several tests for eczema diagnosis, like checking your
blood for allergen levels or the skin patch testing, where
suspected irritants are applied on the skin to see if there
is an allergic reaction.
Treatment
Most treatments for eczema are aimed to lessen the
inflammation and relive the itching, as well as prevent
their recurrence and flare-ups in the future. Due to the
different possible causes of eczema, it is hard to have one
standard cure for it. The good thing is that the different
things you can do to ease the symptoms generally work on
all but the most serious of cases.
Avoid using detergents as much as possible. Detergents
can exacerbate the skin irritation eczema sufferers are
subjected to. Most detergents are made from petrochemicals,
which increase the skin membrane's permeability. Sodium
lauryl sulphate, for example, which is a common household
detergent, has been shown to amplify the penetration of
antigens on your skin.
When washing dirt off your skin, use normal water as
much as possible. Use cleansers only if water is not
enough.
Moisturize your skin. Dry skin is one of the factors
that worsens eczema. Therefore, it is important that you
keep your skin moisturized and moistened. Do not use
detergents and soaps, as these can strip the skin of its
natural oils, leading to more dryness. Use moisturizing
body wash or emollients instead. Aqueous creams maintain
the skin's natural oils and may even reduce your need to
moisturize your skin. For severely dry skin, however, use
thicker ointments, as light aqueous creams might not have
much of an effect on it.
Apply emollient creams and lotions directly after
bathing to lock in the moisture. You can also use
moisturizing gloves to keep the emollients in contact with
your skin when you sleep at night. For unbroken skin, you
can opt to directly use waterproof tape to improve skin
integrity and moisture levels, allowing your skin to heal
better. Using this treatment can also put a stop to the
itching as well as prevent the skin from cracking,
especially since you won't be scratching as much.
Use antihistamines and anti-inflammation creams. Itching
can be the cause of allergens wreaking havoc on your skin.
Antihistamines essentially block the effects of histamines
in your body, preventing allergic symptoms like itching.
Diphenhydramine, hydroxine, and cyproheptadine are some
examples of antihistamines that appear to be the most
effective. Stopping the itching will cause you to stop the
scratching, avoiding the risk of skin breakage and
infection.
Inflammation can be controlled by corticosteroid creams
and lotions. Most doctors prescribe glucocorticoid, but for
mild to moderate cases of eczema, hydrocortisone can be
used. Generally, most physicians prescribe the less potent
ones first and gradually climb the potency ladder if the
treatment doesn't work. However, it should be noted that
corticosteroids can have possible side effects like skin
thinning and fragility. As such, they should be used
sparingly; only apply them to control eczema, and once
accomplished, they should be replaced with emollients. As
always, it is advised that these treatments be made under
the supervision of a physician.
Bathe with care. Some doctors advise against prolonged
bathing when you have eczema. However, bathing is needed
for one important reason: hydration. Your skin needs the
water to remain moist, eliminating dry skin and flaking.
Bathing is generally more recommended than showering.
However, there are several things you need to keep in mind
when you bathe.
* Keep the water lukewarm, not hot nor cold.
* Long, hot showers are not advised.
* As much as possible, do not use any soap. Like
detergents, most soaps can remove the skin's natural
oils.
* Remove perfumed products and never use bubble
baths.
* When rinsing after a shampoo, be careful to avoid skin
contact as much as possible.
* Use emollient bath oils.
* After bathing, pat your skin with the towel, don't rub
it.
If your skin condition does not improve after a couple
of weeks, or if the symptoms worsen even with the
above-mentioned tips, get in touch with your physician as
soon as possible. The dermatitis might be a symptom of a
more severe underlying condition.
