What Is An Allergy?

Theres a lot of talk about allergies. But just what
is an allergy and what causes them? Why do some people
have them while others dont? And why are people with
one allergy more inclined to have many?

The immune system is set up to protect our bodies from
harmful, foreign substances. Like viruses and bacteria
(dirt and germs). Sometimes the immune system doesnt
develop properly or is just oversensitive and doesnt
react right.

In these cases, it reacts to things that arent
harmful and dont usually cause people any problems.
These things are called allergens. The term allergens
is just an easier way to say things that cause
allergies.

When the oversensitive or improperly developed immune
system sees these allergens, it sends out chemicals
like histamine. Its the histamines that cause the
symptoms that are common with allergies.

Symptoms like itching, watery eyes, runny nose,
swelling, hives or rashes. Different people have
different symptoms, but the causes are the same.

The symptoms that are displayed depend on the part of
the body the allergen comes in contact with. Allergens
that are breathed in, like pollen or dust cause
coughing or wheezing, stuffy or runny noses and an
itchy nose and throat.

Plant allergies usually come in contact with the skin,
so they cause rashes.

Food allergies usually result in nausea, vomiting,
stomach pains or in severe cases, life threatening
reactions. Drug allergies tend to involve the entire
body, so they have a variety of symptoms.

Heres A Test To Fail

To diagnose an allergy, the first thing your doctor
does is talk with you. Hell discuss your symptoms,
any medications youre currently taking, and your
personal and family history. A physical examination is
also necessary.

The next step is the tests. There are 3 types of
tests. The skin test, patch test or blood test.

The skin test is the most common test used. Its
generally the most accurate and certainly the least
expensive. With the skin test, a small amount of an
allergen is put on your skin and then the spot is
pricked or scratched with a needle. You can also have
a little bit of the allergen injected into the outer
layer of your skin.

If you have an allergy to the substance that was used,
youll have swelling, redness and itching in the
tested spot within 20 minutes.

The patch test is used to diagnose contact dermatitis.
A small amount of allergen is put on your skin and
covered with a bandage. Your doctor will check the
spot in 48 hours to see if youve developed a rash.

The third type of test is the blood test. This may be
used if you have a skin condition or if youre taking
some type of medication that might interfere with a
skin test.

A blood sample is taken and sent to a laboratory.
There they add allergens to the sample and measure the
amount of antibodies that are produced to attack it.

Corticosteroid Creams and Ointments Are Commonly Used For Eczema Treatment

Corticosteroid Creams and Ointments Are Commonly Used For Eczema Treatment

Corticosteroid medication is usually prescribed for eczema treatment because these are derivatives of something we naturally produce in our adrenal glands. It helps us manage the inflammation especially in the case of eczema and against other skin disorders.

There are two ways that this medication is given namely topically or orally. When we say topically, this is applied to the skin and the absorbed by the body.

Once applied, they stop the skin cells from producing various forms of inflammation that are released when they come into contact with an allergen or irritation. Thus, you are able to reduce the inflammation and in some cases relieve the itchiness.

Examples of topical corticosteroids for eczema include betametasone, fluticasone, hydrocortisone and mometasone. This is available in creams, lotions and ointments which can be purchased over the counter.

It must be pointed out that there are 4 different strengths for topical corticosteroids namely mild, moderate, potent and very potent. Hydrocortisone is used for mild and moderate cases of eczema while the others are used in potent and very potent cases of this skin condition.

In some cases, you will have to use one or two different types for different parts of the body but when you have to take it, remember that the more potent it is, the shorter the time that you have to use it rather than suffering the side effects.

The most common side effect is the thinning of the skin which usually results to permanent stretch marks later on. Your blood vessels may also swell and become prominent under the skin surface. You may even look like someone beat you up because these will appear like bruises. This is why doctors rarely recommend this to patients when the skin is already inflamed.

In rare cases, the use of corticosteroids may cause growth suppression or adrenal suppression. You have to remember that these are also naturally produced by the body and if this should happen, you may not be producing the same number as you are used to.

Children are the ones who are at a higher risk of experiencing these side effects. To prevent this from happening, their case should be monitored by a trained dermatologist.

To reduce the risk of side effects, you have to use corticosteroid creams or ointments that are the least potent. When you apply it to your skin, make sure that this is confined only in the area where the skin disease is present. If this is prescribed by your doctor, make sure that this is only applied once or twice in one day.

When eczema is finally under your control, stop using it. Just use moisturizers to prevent flare ups from taking place because corticosteroid creams or ointments can only reduce the symptoms and not make this go away.

Although corticosteroid creams or ointments are common, you should know that women who are pregnant should never use it. Studies have shown that using it could endanger the fetus and result and abnormalities when the child finally comes out of the womb. It is also not safe for nursing mothers so the child does not absorb the steroids when it is time to feed them.

It is for these reasons that if you have this skin disorder, you should ask your doctor about other forms of eczema treatment like light therapy or wet wrap therapy.
