Psoriasis: causes, diagnosis and treatment

Psoriasis affects about 4% of the population of the globe. It can develop at any age from birth to old age, but is most often psoriasis "loves" the young. This is evidenced by the fact that 70% of patients develop psoriasis before the age of 20 years.

If a rash that resembles psoriasis should consult a dermatologist. Psoriatic lesions represent the itchy scaly plaques of various sizes. When plaque psoriasis can appear on the elbows, knees, scalp or other parts of the body.


Causes of psoriasis

Psoriasis is an abnormal reaction of the body to external stimuli, which in some parts of the body the top layer of skin dies a lot faster than normal. If you normally have a cycle distribution and maturation of skin cells takes 3-4 weeks, in psoriasis, this process happens only 4-5 days.

Currently, psoriasis is considered a genetic disease: the basis of the disease is not one but a whole host of reasons – immunological changes and metabolic disorders associated with hormonal and neurological disorders. You can say that psoriasis is not contagious, and therefore is not a contagious disease.

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

One theory is that there are two types of psoriasis:

  • Psoriasis type I is to appeal to a hereditary defect in the immune system. This form of psoriasis affects about 65% of the people, and the disease occurs in young people, 18 to 25 years.
  • Psoriasis type II occurs in people over 40 years. This type of psoriasis is inherited and is not associated with breakdown of the cells of the immune system. In addition, unlike psoriasis, type I, which favors the skin, psoriasis type II more often affects the nails and joints.

According to another theory, the cause of psoriasis are the only immunity disorders is due to several factors: it may be due to stress, or infectious diseases, or cold climate, or poor diet. For example, noted that alcohol can cause exacerbation of psoriasis, especially beer, champagne and spirits. Use products that contain vinegar, pepper, chocolate, also aggravate the disease and can cause exacerbation of psoriasis. According to this theory, psoriasis is a systemic disease. This means that if serious violations of the immune system, the process can spread to the other organs and tissues, e. g., joints. As a result, may develop psoriatic arthritis, which is characterized by damage to the small joints of the hands and feet.
