The causes of psoriasis
Psoriasis is an abnormal response of the body to external stimuli, in which the parcels of the body from the upper layer of the skin dies a lot faster than normal. If usual, the cycle of division and maturation of cells of the skin occurs in 3 to 4 weeks, in the case of psoriasis, this process occurs in only 4-5 days.
At the present time the psoriasis consider hereditary multifactorialnyh of the disease: the disease is not the only one, and a complex of reasons immunological changes in metabolic, endocrine disorders and neurological disorders. When this thing is for sure psoriasis is not infectious, and therefore is not a contagious disease.
The reasons of occurrence of psoriasis up to now, was ultimately not found. On this account there are different theories.
According to one theory, there are two types of psoriasis:
• Psoriasis type I is called transmissible by inheritance of a failure of the immune system. This form of psoriasis suffer from about 65% to men, in which the disease manifests at a young age, from 18 to 25 years.• Psoriasis type II occurs in people over 40 years of age. With this type of psoriasis is not hereditary and is not related to a failure in the cells of the immune system. And, unlike psoriasis, type I, which like the skin, psoriasis type II occurs most frequently in the nails and joints.
According to another theory, the cause of psoriasis are exclusively of the infringement of the immunity, caused by many different factors: it could be stress, or infectious disease, or cold, or a bad power supply. For example, it is mentioned that alcohol can cause exacerbation of psoriasis especially beer, champagne, spirits. The consumption of products containing vinegar, pepper, chocolate, deteriorates also the course of the disease and can cause a worsening of psoriasis. According to this theory, psoriasis is a systemic disease. This means that in the event of serious violations in the functioning of the immune system, the process can spread to other organs and tissues, for example, on the joints. As a result, it can develop psoriatricheskii arthritis, which is characterized by the defeat of the small joints of the hands and feet.
