Currently, psoriasis is considered hereditary diseases: on the basis of the disease is not one but a whole range of reasons – immunologic changes, and metabolic disorders associated with endocrine and neurological disorders. We can say that psoriasis is not contagious, and therefore is not infectious disease.

Causes of psoriasis are still not completely found. On this score there are a variety of theories.

According to one theory, there are two types of psoriasis are:

  • Psoriasis type I, which is necessary for the inherited defect of the immune system. This form of psoriasis affects about 65% of the people, and the disease, which is manifested in his youth, from 18 to 25 years.
  • Psoriasis type II, which occurs in people older than 40 years. With this type of psoriasis is not hereditary and is not associated with defects in cells of the immune system. In addition, in contrast with psoriasis type I prefer skin, psoriasis type II more often affects the nails and joints.

According to the other theory, cause of psoriasis, which are exclusively immunity to interference caused by various factors: it can be stress, or infectious diseases, or cold climate, or poor nutrition. For example, has found that alcohol can cause exacerbation of psoriasis, especially beer, champagne, spirits. Use of products that contain vinegar, pepper, chocolate, also worsens the disease and can cause exacerbation of psoriasis. According to this theory, psoriasis is a systemic disease. This means that in the case of serious violations of the immune system, a process may spread to other organs and tissues, e.g., joints. As a result, may develop psoriatic arthritis, which is characterized by lesions of small joints of the hands and feet.
