Psoriasis

What is Psoriasis?

Psoriasis is a chronic skin rash with red, thickened areas of skin with silvery scale. It most commonly affects the scalp, elbows, knees, lower back, belly button, and buttocks, but can affect any area of the body. It ranges from mild to very severe, in some cases covering large areas of the body. It is fairly common, with two out of every 100 people affected.

Is it contagious?

Psoriasis is not contagious and cannot be passed from one person to another. However, it is most likely to occur in members of the same family.

What causes Psoriasis?

The cause of psoriasis is unknown, although it has a genetic basis. Most studies point to an abnormality in white blood cells called T cells that trigger inflammation and the immune response in the skin. Because of the inflammation, the skin grows too rapidly. Normal skin replaces itself in about 30 days while, with psoriasis, the process speeds up to three to four days.

What makes Psoriasis appear?

A “trigger” is usually needed to make psoriasis appear. It can be caused by stress, an infection (i.e. strep throat) and by taking certain medications. Cold, dry winter weather and lack of sunlight can also trigger psoriasis. Others see it flare 10 to 14 days after their skin is injured by a cut, scratch or severe sunburn.

How is Psoriasis treated?

The goal of Psoriasis is to reduce the inflammation and the shedding of the skin. Treatment may include:

Topical medications
Oral medications
Light therapies
Injections

Can psoriasis be cured?

No. While it cannot be cured, a number of treatment options can help manage it.
