Psoriasis is a chronic disorder of the skin characterised by reddish, scaly sections of inflammation. Psoriasis is generally found on the arms, legs, trunk, nails, or scalp, but it may be noticed on almost any part of the skin. The most commonly affected areas would be the knees and also elbows.

Psoriasis is an immune system affliction that impacts both females and males. Estimates vary but somewhere between 4.5 and 7.5 million people inside the U.S. have been diagnosed with psoriasis. 150,000 new cases are diagnosed every year. Psoriasis is not contagious. It isn't something you can "catch" or that others can catch from you. Psoriasis lesions will not be infectious.

Thick, scaly, red plaques will be the hallmark of psoriasis. In psoriatic skin, the cells belonging to the outer layer (epidermis) multiply too rapidly, which causes skin to thicken. Additionally, they adhere to each other more strongly and for longer than normal skin cells do, causing scaliness. The skin is infiltrated by white blood cells, causing inflammation, redness, and infrequently pustules.

Exactly why this happens isn't yet well understood, but genetics are clearly involved. Ancestors and family history can affect who's diagnosed with psoriasis - if a parent has psoriasis, a child carries a 10 percent chance of developing it as well. However, the correct psoriasis triggers also needs to exist before symptoms start to appear.

Researchers now believe there may be an ethnic connection to Psoriasis, since it is most common in Caucasians throughout the US and Northern Europe. Additionally, genetics seemingly plays a role. Studies have shown that one-third of people diagnosed with psoriasis have at least one close relative with the condition. A study conducted in the US found the occurrence of psoriasis was 2.5% in Caucasians and 1.3% in African Americans.

Psoriasis can be mild or severe. When it's , adversely affect functions of daily for example work and social activities.

There is as yet no complete cure for psoriasis. Treating psoriasis depends upon its severity and location. Medical treatments vary from local (cortisone cream application, emollients, coal tar, anthralin preparations, and exposure to the sun) to systemic (internal medicines, which includes methotrexate and cyclosporine).

Moreover, there are several natural and alternative healthcare treatments based on psoriasis natural treatment which have proved to be effective. Every person with psoriasis is different. That which is the best psoriasis treatment for one may not work at all for another.
