Psoriasis is an inflammatory skin disease characterized by the appearance of pinkish spots with clearly defined boundaries on various parts of the body and with increased desquamation of the epithelium on the surface of the lesions. Psoriasis is a disease of the century, since this type of skin pathology affects millions of people around the world. Currently, the cause of psoriasis has not been established, but it is assumed that hereditary (genetic) factors are involved in the development of this disease a major role.  

The nature of the disease

Psoriasis is a chronic, often recurrent skin inflammation that occurs throughout a person’s life. At the initial stage, the disease is accompanied by significant lesions of small areas of the skin in any anatomical area of ​​the body. With a sufficiently long course of the disease, the lesions spread and capture large areas of the epidermis.

The main symptoms of psoriasis: the formation of pinkish spots on the skin, the surface of which is characterized by flaking, a feeling of “drawn in” and dry skin, itching and burning, hardening of the skin. The process of diagnosing this disease is carried out when characteristic formations appear on the skin.

There are three layers in the structure of skin tissues: epidermis, hypodermis and dermis. The epidermis is the surface layer of the skin. It consists of special cells, which, in the process of division and vital activity, form the so-called stratum corneum, consisting of horny scales. As they die off, the smallest scales naturally peel off, and in their place cells appear from the deep layers of the skin. Thanks to such processes, the skin of the human body is constantly renewed.

The season when psoriasis is a neuro-allergic disease is in progress – winter. However, exacerbations can be triggered by prolonged exposure to the sun, various infectious diseases, injuries, etc.  

With an exacerbation of psoriasis, new papules are formed (vesicular rashes on the skin), in the stationary stage, the appearance of papules stops, the existing ones begin to fade. During regression, the papules turn pale, decrease in size, and cease to rise above the surface of the skin. Peeling stops and itching decreases.

Psoriasis is an inflammation of the upper layers of skin tissue, that is, the epidermis. For unknown reasons, in people who suffer from psoriasis, the cells of the lower layers of the epidermis divide at a faster rate than in the absence of the disease, which leads to the rapid rejection of the surface layers of the epidermis and is caused by excessive flaking of the skin.

Causes of occurrence

For what reason psoriasis develops , a disease that is so widespread in our time, has not yet been established. However, there is a point of view that the main factor affecting the possibility of the onset of the disease at any age period is human heredity. 

In addition, some reasons have been identified that provoke the development of psoriasis. The primary and main cause of psoriasis is considered to be disturbances in the functioning of the nervous system, which are the result of constant nervous tension, emotional breakdowns and stresses that occur in the life of a modern person. In addition, the disease can be caused by various infectious diseases, skin injuries, sunburn, alcohol consumption, HIV infection, as well as the use of certain foods and the intake of potent drugs (an allergic reaction of the body).

Most studies have confirmed the version that psoriasis is not a contagious disease, and is not transmitted to others through contact or airborne droplets.

If you have any signs of psoriasis, you should see your doctor urgently. Treatment of psoriasis is a laborious process, which for the most part does not lead to a complete cure, but only translates the disease into a stage of remission, which is usually considered as a positive result of the therapy undertaken.
