About Psoriasis



What is Psoriasis?
Psoriasis is a skin disease that is caused by a response from the body’s immune system. It occurs when the immune system fails to recognize normal skin cells and sends out signals to trigger a response that would normally be the result of a pathogen. This results in too many new skin cells being produced. The name “Psoriasis” is Greek and means “itching condition”. There are no cures for psoriasis skin diseases, only a number of treatments that can be used to keep symptoms under control.promoimg1.png

When symptoms first occur, the person may think they simply have dry skin. Once the psoriasis is full-blown, there is usually a red rash that is topped by silver scales. The skin disease is not contagious but it has been linked with a higher risk of stroke. Not all psoriasis is the same. Five distinctive types occur including: guttate, plaque, erythrodermic, inverse and pustular. Either form is chronic, recurring in various degrees of severity from localized patches to coverage over the entire body.

No one understands exactly what causes psoriasis although genetics are thought to play a role. Outbreaks of the disease are also thought to be caused by certain triggers, such as injuries to the skin. Some experts believe that a variety of environmental factors can also aggravate or cause symptoms. These include psychological stress, oxidative stress, withdrawing systemic corticosteroids and more. The biggest challenge in treating psoriasis skin diseases is their tendency to recur. Using and withdrawing from the use of corticosteroids can end up making the condition worse.

Symptoms of Psoriasis
Symptoms for psoriasis sufferers vary, depending on which of the five types the individual has. Most include the red, itchy patches covered with silvery scales and they may include small scaling spots, dry, cracked skin, burning or soreness. Those with nail psoriasis will typically see thickened nails that may be pitted or have ridges. The disease can also cause swollen, stiff and painful joints. Just as the psoriasis may cover anywhere from minor areas to the entire body, the symptoms may be mile to painful and even disfiguring.

There are many treatments available, but because of its chronic recurrent nature, psoriasis is a challenge 

to treat. Withdrawal of corticosteroids (topical steroid cream) can aggravate the condition due to
the 'rebound effect' of corticosteroids.


Psoriasis can affect children. Approximately one third of psoriasis patients report being diagnosed before
age 20. Self-esteem and behavior can be affected by the disease. Bullying has been noted in clinical research.

Psoriasis is the most common autoimmune disease in the U.S.A
as many as 7.5 million Americans have psoriasis.
