What is psoriasis?

Psoriasis is a skin condition that lasts for a long time.

It is classified as an autoimmune disorder.

This suggests that instead of defending the body, your
immune system is harming it.

This disease affects about 7.4 million people in the United



Psoriasis causes the skin to grow scaly patches that are
itchy and uncomfortable and may be silvery or red.

The patches will last anywhere from a few days to more than
a month.



There are several types of psoriasis, and you can have more
than one.

Continue reading to learn more about these various types and
how they are treated.

What does psoriasis look like?


The most common psoriasis symptoms are: red patches of skin
that are scaly, sometimes silvery, and skin patches.

Psoriatic arthritis is characterized by itchy skin and joint
swelling, stiffness, or pain.

The symptoms of psoriasis differ depending on the type.

Psoriasis is classified into five types:

erythrodermic plaque guttate inverse pustular plaque

Mental stress, anxiety, and low self-esteem can all be
symptoms of psoriasis.

People with psoriasis are also prone to depression.


There are also different types of psoriasis.

These appear differently depending on where the body is

Psoriasis, regardless of type, is not contagious.


Plaque psoriasis

The most common type of psoriasis is plaque psoriasis, also
known as psoriasis vulgaris.

Plaque psoriasis affects 80 to 90 percent of people with

It is distinguished by thick red patches of skin with a silver
or white scaly layer.


These patches are commonly found on the elbows, knees, and

scalp on the lower back

Patches are typically 1 to 10 centimeters wide, but can be
larger and cover a larger area of the body.

Scratching at the scales often worsens the symptoms.



To alleviate discomfort, your doctor may advise you to use
moisturizers to keep your skin from becoming too dry or irritated.

Over-the-counter (OTC) cortisone cream or ointment-based
moisturizers are examples of these moisturizers.

Your doctor may also work with you to identify your specific
psoriasis triggers, such as stress or a lack of sleep.

Other treatments may include: vitamin D creams, such as
calcipotriene (Dovonex) and calcitrol (Rocaltrol), to slow the rate at which
skin cells grow topical retinoids, to help reduce inflammation medication such
as tazarotene (Tazorac, Avage) applications of coal tar, either as a cream,
oil, or shampoo biologics, a class of anti-inflammatory drugs.

In some cases, light therapy may be required.

This entails subjecting the skin to both UVA and UVB rays.

To reduce inflammation, some treatments combine prescription
oral medications, light therapies, and prescription ointments.

Systemic medication in the form of oral, injectable, or
intravenous medication may be prescribed in moderate to severe cases.

Guttate psoriasis

Guttate psoriasis manifests itself as small red spots on the

It is the second most common type, affecting approximately
8% of psoriasis patients.

The majority of the time, it begins in childhood or early

The spots are tiny, distinct, and drop-shaped.

They are most commonly found on the torso and limbs, but
they can also be found on the face and scalp.

Spot psoriasis is usually not as thick as plaque psoriasis,
but it can progress to plaque psoriasis over time.

Guttate psoriasis develops as a result of certain triggers.

These are some of the triggers:

Medication for strep throat, stress, skin injury, and


Your doctor may prescribe steroid creams, light therapy, and
oral medications to treat guttate psoriasis.

Identifying the source of the infection can also aid in the
treatment of guttate psoriasis.

Antibiotics may be beneficial if the condition was caused by
a bacterial infection.

Flexural or inverse psoriasis


Flexural psoriasis, also known as inverse psoriasis, is a
type of ps

Flexural or inverse psoriasis frequently appears in
skinfolds, such as under the breasts, armpits, or groin.

This form of psoriasis is red, shiny, and smooth.

This type of psoriasis is prevented from shedding skin
scales by sweat and moisture from skinfolds.

It is occasionally misdiagnosed as a fungal or bacterial

Inverse psoriasis can be exacerbated by skin-on-skin


Most people who have inverse psoriasis also have psoriasis
in other areas of their body.


Inverse psoriasis treatments are similar to plaque psoriasis

They may include the following:



steroid creams for the skin


light therapy oral medications biologics available by
injection or intravenous infusion

To prevent your skin from thinning too much, your doctor may
prescribe a lower potency steroid cream.

You may also benefit from taking or applying medications
that inhibit the growth of yeast or bacteria.

Pustular psoriasis

Pustular psoriasis is the most severe type of psoriasis.

It appears quickly as a swarm of white pustules surrounded
by red skin.

Pustular psoriasis can affect isolated areas of the body,
such as the hands and feet, or it can cover the entire surface of the skin.

These pustules can also connect to form scaling.

Some people go through a cycle of pustules and remission.

While the pus is noninfectious, this condition can cause
flu-like symptoms such as:


fever chills rapid pulse muscle weakness loss of appetite

Pustular psoriasis is classified into three types:

von Zumbusch palmoplantar pustulosis (PPP) acropustulosis


The symptoms and severity of the three types of pustular
psoriasis vary.


Corticosteroid creams, either over-the-counter or
prescribed, oral medications, or light therapy may be used to treat the

Biologics may also be recommended.

Identifying and treating the underlying cause of pustular
psoriasis may also help reduce recurrence.

Erythrodermic psoriasis

Erythrodermic psoriasis,
also known as exfoliative psoriasis, is a rare type of psoriasis that resembles
severe burns.

The situation is critical
and could result in a medical emergency.

You may require
hospitalization if your body is unable to regulate its temperature.

 This type of psoriasis is
common, red, and scaly.

It has the potential to
cover a large portion of the body.

Exfoliation is frequently
in larger pieces than the small scales seen in most psoriasis.

Erythrodermic psoriasis
can develop as a result of:

Plaque psoriasis a bad
sunburn infection pustular psoriasis widespread, poorly controlled

Significant stress,
alcoholism, and abrupt discontinuation of a systemic psoriasis medication


A person with this
condition frequently requires hospitalization.

You will receive a
combination of therapies at the hospital.

Medicated wet dressings,
topical steroid applications, biologics, or prescription oral medications may be
used until symptoms have improved.

If you suspect you have
erythrodermic psoriasis, consult your doctor.


Psoriatic arthritis

Psoriatic arthritis (PsA)
is a painful and physically limiting condition that affects 30 to 33% of
psoriasis patients.

There are five types of
PsA, each with its own set of symptoms.

This condition is also

As an autoimmune disease,
psoriasis can cause the body to attack the joints and skin.

It can affect many joints
and is frequently severe in the hands.

Typically, skin symptoms
appear before joint symptoms.


Nonsteroidal anti-inflammatory
drugs (NSAIDs) such as ibuprofen (Advil) and naproxen sodium can be used to
treat psoriatic arthritis (Aleve).

NSAIDs can aid in the
reduction of swelling and pain associated with psoriatic arthritis.


Prescription medications,
such as prednisone, an oral corticosteroid, may also aid in the reduction of
inflammation that causes psoriatic arthritis.

Salicylic acid,
calciopotriene, and tazarotene are prescription topical medications used to
treat psoriatic arthritis.


Light therapy may also be
beneficial in reducing symptoms.


antirheumatic drugs (DMARDs) are a class of medications that can help reduce
inflammation and joint damage.

Biologics are substances
that are biological in nature.

DMARDs, a subclass of
DMARDs, may be prescribed to reduce inflammation at the cellular level.

Nail psoriasis

Nail psoriasis is a symptom of psoriasis,
but it is not an official form of psoriasis.

Fungal infections and other nail infections
are often confused with this disease.



Psoriasis of the nails will result in:

Discoloration of the nail pitting grooves
loosening or cracking of the nail thickened skin under the nail colored patches
or spots under the nail

The nail will crumble and fall off at times.

While there is no remedy for psoriatic
nails, certain therapies may improve their health and appearance.
