Causes of psoriasis
Psoriasis – it is an abnormal body reaction on external irritants whereby in some parts of the body the upper layer of the skin dies faster than usual. If normal cycle of division and maturation of the skin cells happens in 3-4 weeks, then during psoriasis this process is occurring within 4-5 days.
Currently, psoriasis is considered as a hereditary multi factorial disease: the basis of the disease is not one but a whole range of reasons – immunological changes, metabolic disorders, endocrine and neurological disorders. It is possible to say for sure: psoriasis cannot be shared with the touch, and therefore this is not an infectious disease.
Causes of psoriasis are still not found. Today exist various theories. According to one theory, there are two types of psoriasis.
Psoriasis type 1 is caused by inherited breakdowns in the immune system. 65% of all population suffering from this form of psoriasis, in the same time this disease appears in young age(from 18 until 25 years).
Psoriasis type 2 affecting oldpeople(40 years and older). This type of psoriasis is not inherited and does not have a relation with breakdowns in the immune system. The difference between this two psoriasis is that type 2 attacking nails and joints, unlike the type 1 which attacking the skin.
According to another theory, the reason for psoriasis is immunity disorders caused by various factors: it could be stress or infectious diseases, cold climate, or an unhealthy diet. For example, it is proved that alcohol can provoke exacerbation of psoriasis – this is especially true for a beer, champagne, and other alcoholic drinks. Eating foods that contain vinegar, pepper, chocolate aggravates the disease and can cause exacerbation of psoriasis. According to this theory, psoriasis is a systemic disease. This means that in case of serious infringements in the work of the immune system, the process can spread to other organs and tissues such as the joints. As a result, it may develop psoriatic arthritis, which is characterized by the defeat of the small joints of the hands and feet.
