If, in general, the cycle of division and maturation of cells of the skin occurs in 3-4 weeks, when the psoriasis, the process occurs in just 4 or 5 days.

Currently, the psoriasis considered a genetic disease: the basis of disease is not a, but a complex set of causes immune shifts, metabolic, attendant of endocrinology and neurological disorders. One can say with certainty: the psoriasis not infectious, and, therefore, is not a contagious disease.

The cause of psoriasis is still not completely found. On this point, there are several theories.

According to one of the theories, there are two types of psoriasis:

  • Psoriasis type I is called diseases of the inheritance of failures of the immune system. This form of psoriasis suffer around 65% of people, being that the disease manifests at a young age, from 18 to 25 years.
  • Psoriasis type II manifests in people older than 40 years. With this type of psoriasis is not hereditary and is not related to the faults in the cells of the immune system. In addition, in contrast with psoriasis type I, that you prefer the skin, psoriasis II is the type that most affects the nails and joints.

According to another theory, the cause of psoriasis are solely from the violation of the immunity caused by several factors: it can be stress or infectious diseases, or cold climate, or poor nutrition. For example, it was observed that the alcohol can cause the worsening of psoriasis — this applies especially to beer, champagne, strong alcohol drinks. The use of products that contain vinegar, pepper, chocolate, and also aggravates the course of the disease and can cause exacerbation of psoriasis. According to this theory, psoriasis is a systemic disease. This means that, when serious irregularities in the functioning of the immune system, the process can spread to other organs and tissues, for example, about the joints. As a result, may develop psoriatic arthritis, which is characterized by a defeat small joints of the hands and feet.
