Psoriasis

Psoriasis is a common skin disorder, which is manifested by reddish flaky inflamed lesions affecting any part of the body, most commonly knees, scalp, elbows & lower back. Most patents complain of having small zones of damaged skin. Their itching and soreness can be felt in some cases.
About 2% of the British suffer from this disease. The most vulnerable category is under 35-year-olds, though psoriasis may affect people of different ages irrespective of their sex.
This skin disorder can have different degrees of severity from causing slight irritation to affecting entirely the life quality. There are different types of it, for example: scalp psoriasis, nail psoriasis, plaque psoriasis and others. But the treatment doesn’t depend on the certain type, it depends on the complexity of the disease.

Medical professionals haven’t succeeded in substantiating the disease cause yet. However, they tend to relate it to the immune system disorder. In normal health conditions, the immune system serves as human body protector against infections & diseases, but in psoriasis, it starts attacking skin cells. Therefore, this disease is classified as an autoimmune one.
Sometimes, psoriasis affects several generations of one family, though positive family history hasn’t been proved yet. Medical experts are unanimous in emphasizing the trigger of the disease, which can be a skin injury, a throat infection, or a negative effect of taking certain drugs. Fortunately, healthy people don’t have to be afraid of being infected by psoriasis-affected family members or acquaintances as the disease is not contagious.
