Psoriasis: Causes Of Psoriasis

What Causes Psoriasis?

The exact cause of psoriasis is unknown. It is believed that the abnormal functioning of T-cells in the blood has some role to play in development of psoriasis. Let us find out about what happens in the skin during psoriasis. As you know the skin renews itself continuously. Normally, it takes about a month for new cells from the bottom of the skin to reach the top and shed the old cells. In psoriasis, this time reduces to three or four days. That is the reason of the red patches and white scales. These are dead skin cells that are shedding very fast abnormally.

Psoriasis gets triggered by skin cuts, sunburn, bruises, throat infections or stress. Some medicines can also trigger psoriasis. It is hereditary to a certain extent. Any time during your lifetime, psoriasis may get triggered, but normally the after-teen years and late 50's are the ages when it gets triggered. As soon as you see red scaly patches with silver white scales, meet your doctor and get diagnosed. Doctors diagnose psoriasis by examining the affected skin. If there is any doubt in diagnosis, a biopsy may be taken.
