The causes of psoriasis
Psoriasis is an abnormal reaction of the organism to external stimuli, in which in distinct areas of the body the top layer of the skin wilt much faster than normal. 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 believe hereditary multifactorialnyh of the 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. The result can develop psoriatricheskii arthritis, which is characterized by a defeat small joints of the hands and feet.

Depending on the seasonality of recurrence (worsening of disease) distinguish three types of psoriasis: winter, summer, uncertain. It occurs more frequently in the winter type of psoriasis.
In the period of exacerbation of the manifestation of psoriasis on the hands, on the lap, on the head, and also in the lower part of the back and in the locations of skin folds act in the form of plates, of a reddish colour. Their dimensions vary from a pinhead to large areas the size of a palm of the hand, and more.
The rash is usually accompanied by the bark and excruciating itching. In the process of peeling of the surface flakes are more dense, localized in depth (hence the second name of psoriasis — flake ringworm). Sometimes, in the field of affected areas of the skin cracks and abscesses.
For the progressive psoriasis characterizes the so-called phenomenon Kebnera: the development of plaques in places of injuries or scratches on the skin.

When significant manifestations of the disease use the following methods of treatment of psoriasis:• cryotherapy — a method of cold impact;

In any case, do not try to alone involve the treatment of psoriasis ultraviolet without the doctor's recommendation. When the psoriasis is a small dose of ultraviolet radiation are medical, and high — on the contrary, can podhlestnut the development of the disease. The same applies to sunlight baths.
