What is Psoriasis Disease?

Psoriasis is a skin disorder in which red, scaly rashes appear on the skin. Psoriasis is not an infectious disease else a recurrent disease that can become worse over time.

In psoriasis disease, the life cycle of skin cells increases. In normal condition, the skin cells start growing inside and reach the surface of the skin once a month, but in the state of psoriasis, the cells come on top of the skin within 14 days and are destroyed. The skin affected by psoriasis becomes red and flaky.

What Causes Psoriasis?

Psoriasis disease is characterized by an autoimmune reaction. Disturbance of the immune system of the body is considered to be the cause.

Human skin takes about 28 days to replace old cells and create new cells, but the skin of people with psoriasis produces new cells in just 4 to 5 days. This causes the cells to freeze. This eventually causes red, dry and itchy patches on the skin.

Psoriasis can engulf anyone of any age, but the highest number of cases have been observed in the people aged 15 to 35 and older. The following points can be included behind the development of this skin disease —

  • Bacterial or virus infection
  • Stress
  • Sunburn
  • Skin injuries — skin bites, burns, insect bites, and rashes
  • Side effects of medicines, including medicines such as anti-malaria

Psoriasis can be more deadly for people whose immune system is weak or who have HIV/AIDS.

Types of Psoriasis

Psoriasis occurs when the skin cells life cycle become fast, resulting in a rapid buildup of dead and rough skin cells. These skin cells assemble, forming dry, red patches and thick silvery scales that are sometimes itchy or painful. In many cases, pus-filled blisters also appear.

Sign and symptoms of psoriasis may vary from person to person and typically identified by their hallmark appearances. They include —

1. Plaque Psoriasis

Plaque psoriasis is the most common form of psoriasis. It causes raised, dry and red skin lesions covered with silvery scales. It may be painful and can occur anywhere on the body. You may have few plaques or many. The skin around the joints may crack and bleed.

2. Scalp Psoriasis


Scalp psoriasis can cause red, itchy skin with silvery-white scales. In children, scalp psoriasis often first appears on the scalp.

Symptoms may include flakes of dead skin in the hair or on the shoulders, especially after scratching the scalp.

3. Nail Psoriasis


Nail psoriasis can affect your fingernail and toenails. It causes pitting, discoloration and abnormal nail growth. In this type of psoriasis, your nails may become loose and nail may detach from the nail bed (onycholysis).

4. Guttate Psoriasis

Guttate Psoriasis Symptoms

Guttate psoriasis is especially associated with strep infection in children (bacterial infection, which causes sore throat and scratches).

In this type of psoriasis, small, red sores mainly on arms, legs and trunk may appear on the skin. The sores aren’t as thick and covered by a fine scale.

5. Inverse Psoriasis


It may cause smooth patches of inflamed and red skin primarily in the groin, armpits, around the genitals and under the breasts. In this, the skin becomes red and irritation also occurs.

6. Pustular Psoriasis

Pustular Psoriasis Symptoms

It may occur in widespread patches or in smaller areas on the fingertips, feet or hands. Pustular psoriasis can develop quickly. It can cause pus-filled blisters appearing just few hours after the skin becomes tender and red.

7. Erythrodermic Psoriasis

Erythrodermic Psoriasis Symptoms

This type of psoriasis is least common.

In this type, the redness on the skin intensifies and covers a large area. Erythrodermic psoriasis can be triggered by corticosteroids, severe sunburn, or another type of psoriasis.

Psoriasis Symptoms

Psoriasis affects your skin. There is a lot of itching on the skin and sometimes the condition can worsen and cause swelling on the skin. Sometimes you can also feel pain. This results in small scaly spots on the skin, dry, cracked skin from which blood can come out.

Many times blisters start forming on the skin. The need for constant itching can be very annoying.

Psoriasis can also affect the joints and cause inflammation in the joints.

Psoriasis Triggers

Common psoriasis triggers may include —

  • Stress — stress is a major trigger for some individuals with psoriasis, either causing psoriasis to flare up for the first time or to make it worse after you’ve been diagnosed. [Trusted Source 1]
  • Excessive consumption of alcohol
  • Smoking and exposure to secondhand smoke — people who smoke have almost double risk of developing psoriasis as compared to the people who’ve never smoked
  • Beta-blockers and lithium — beta-blockers to treat high blood pressure or hypertension and lithium for mental disorder can make psoriasis worse [Trusted Source 2] [Trusted Source 3]
  • Cold weather — people who have psoriasis and live in a cold climate are at a greater risk of having psoriasis disease
  • Infections — skin infections or strep throat
  • Certain medications such as high blood pressure medications and antimalarial drugs
  • Injuries to the skin — a bug bite, cut or scrape, or a severe sunburn

Risk Factors

If someone has psoriasis disease, then he/she is at a greater risk of developing other conditions; including

  • High blood pressure
  • Obesity
  • Type-2 diabetes
  • Psoriatic arthritis
  • Liver disease
  • Kidney disease
  • High cholesterol
  • Cardiovascular disease
  • Family history — those people are at greater risk who have the family history of psoriasis
  • Mental health conditions — low self-esteem, depression
  • Eye conditions — blepharitis, conjunctivitis, uveitis
  • Autoimmune diseases — sclerosis, celiac disease, Crohn’s disease


Your doctor or health care provider will ask questions about your health and will examine your body; including skin, scalp and nails.

Your doctor might take a small tissue from your skin in order to examine it under a microscope. This process is known as biopsy. This will help your doctor to determine the type of psoriasis.

Psoriasis Prevention

There is no way to prevent psoriasis disease, but some things may improve the symptoms. [Trusted Source 4]

Some ways to reduce the risk of a psoriasis flare-up include —

  • Take daily baths
  • Avoid triggers if you can
  • Keep your skin moisturized
  • Get a small amount of sunlight each day

Psoriasis Treatments

Psoriasis treatments may include —

  • Topical therapy
  • Light therapy
  • Oral or injected medication

Topical Therapy

In this type of treatment, creams and ointments are applied directly to the skin to reduce symptoms. It includes —

Topical Corticosteroids :

Corticosteroids are the medications used to treat mild to moderate psoriasis. They are available as cream, lotions, gels, ointments, sprays, foams and shampoos.

It is usually recommended to apply at sensitive areas.

Vitamin D Analogues :

This type of medication may be used alone or along with topical corticosteroids. These are the synthetic forms of vitamin D. Examples may include calcitriol and calcipotriene. They work by slowing down the growth of skin cells.

Calcitriol and calcipotriene are usually more expensive than those of topical corticosteroids.

Retinoids :

 Retinoids are the medication used to regulate the epithelial cell growth. Examples may include tazarotene.

Tazarotene medication is available in the form of gel and cream. You can apply it once or twice daily.

It is not advisable to use tazarotene if you’re pregnant or planning to get pregnant. Do not use this medicine if you are breast-feeding.

Calcineurin Inhibitors :

Calcineurin inhibitors are used to treat various inflammatory skin diseases, especially — atopic dermatitis and psoriasis. Examples are — tacrolimus and pimecrolimus.

They reduce inflammation and plaque buildup and especially helpful in areas of thin skin, such as around the eyes.

It is not advisable to use calcineurin inhibitors if you’re pregnant or planning to get pregnant. Do not use this medicine if you are breast-feeding.

Anthralin :

Anthralin is a cream used to slow down skin cell growth. It can also used to remove scales and make skin smoother.

Salicylic Acid :

Salicylic acid is a beta-hydroxy acid. It is normally used to reduce acne by exfoliating your skin and keeping pores clear.

Coal Tar :

It is used to reduce inflammation, scaling and itching. It is available in various forms; such as oil, shampoo and creams. These products can irritate the skin.

This treatment is not recommended for women who are breast-feeding or pregnant.

Light Therapy

This therapy is used to treat moderate to severe psoriasis, either alone or with other medications. It involves artificial or natural light to treat psoriasis. Sunlight eradicates those hyperactive white blood cells which are attacking healthy skin cells and are rapidly generating cells.

Both UVA and UVB light may be useful in reducing the symptoms of mild to moderate psoriasis. Most people with moderate to severe psoriasis benefit from a combination of treatments.

Oral or Injected Medication

If someone with moderate to severe psoriasis don’t get relief from other treatments, then his/her doctor may prescribe oral or injected medications.

Some of the medications used are —

  • Steroids— If you have psoriasis symptoms such as small and persistent patches, your doctor or health care provider might suggest triamcinolone injection right into the lesions.
  • Biologics— This class of drugs changes your immune system. These drugs are given intravenously via injection.
  • Cyclosporine This drug blocks the immune system response, which can reduce the symptoms of psoriasis. This means that if your immune system is weak, you can get sick easily. Side effects include kidney problems and high blood pressure. These drugs are not recommended if you’re pregnant, planning to get pregnant or breast-feeding.
  • Methotrexate— Like cyclosporine, this drug exerts pressure on the immune system. It may have fewer side effects when used in low doses, but in the long term it can cause serious side effects. This includes liver damage, reduced production of white and red blood cells.
  • Retinoids— These drugs are used to reduce skin cell production. Once you stop using them, there are likely to be symptoms of psoriasis. Pregnant women or women who become pregnant within the next three years should not use retinoid because of the risk of possible birth defects.
