What is Psorasis
Psoriasis is a chronic disease of the skin that is characterized by silvery, scaly raised patches of dead skin.
Causes of Psorasis
People with psoriasis have an abnormally high rate of skin cell maturity. The skin cells mature so rapidly (in less than one week compared with the normal rate of every 28 to 30 days) that the body is unable to shed old cells quickly enough for the new cells to replace them. As the new cells push their way to the surface of the skin, the old cells create a build up of dead skin, which appear as raised patches. Researchers aren’t sure what causes this rapid cell growth, but suspect it is related to a malfunction in the immune system.
Symptoms of Psorasis
Psoriasis usually affects the elbows, knees, back, scalp, and buttocks, but can occur on any part of the body, including the fingernails. In its most common form, psoriasis begins as small, raised patches, called plaques, that grow larger and become inflamed. The inflamed skin gets scaly and flakes off, like dandruff. However, the scales underneath cause bleeding if removed
Symptoms may affect joints on only one side of the body, or on both sides at the same time. The fingernails may also undergo changes, becoming thickened and pitted.
Diagnosis of Psorasis
A diagnosis of psoriatic arthritis is usually made when psoriasis is accompanied by symptoms of arthritis. Your doctor will review your symptoms, carefully examine your skin and nails for indications of psoriasis, and ask about any personal or family history of this skin condition. He or she will also order a blood test to check for the antibodies that indicate rheumatoid arthritis.
