What is psoriasis and what does it appear from?Psoriasis is the non -infectious condition of the skin, the result of which are inflamed red plates, as well as dry stairs - the result of excessively rapid growth in skin cells.The disease more often affects the skin on the elbows, knees and scalp.
In some people, it manifests itself in a mild form, the symptoms are practically absent.Others notice serious, frequent recurrence symptoms.What comes psoriasis, where it comes from, because it appears, the causes of the apparition, how they are infected: we will try to answer these and other questions on the pages of our portal.
Psoriasis is an incurable, long -term (chronic) skin condition.The exacerbation phases are quickly replaced by improvement phases.Many patients notice the aggravation of symptoms from November to February (winter months), as well as in hot summer times.Psoriasis affects all ethnic breeds and representatives of both sexes.Although psoriasis may appear in people of any age - from children to the elderly - very often the disease is diagnosed with adolescence under 20 years.
At what age psoriasis appears?The disease is rare in infants (less than 4% of the sick), in children psoriasis can manifest themselves if parents are bearers of the disease.Psoriasis in such young children is often preceded by acute pharyngitis, tonsillitis, bronchitis or respiratory infection, for example an influence, an influence or pneumonia.People with psoriasis have more chances of obtaining diabetes, hyperlipidemia and heart disease.
Why does psoriasis occur?The causes of psoriasis are unknown at the end, but usually the disease is associated with the problem of the immune system.From what and how does psoriasis appear?The key element is a special type of lymphocytes, called T-Linfocytes or T. Cells normally, these white blood cells move throughout the body to detect and eliminate foreign substances, such as viruses or parasites (streptococcus).However, in patients with psoriasis, T lymphocytes erroneously attack healthy skin cells (to combat a false infection).
Hyperactive lymphocytes cause immune reactions, including the expansion and increase in the vases around the papules and pustules of Pasriase.These changes lead to an increase in the production of healthy skin cells and other white blood cells.This causes an ongoing cycle, against which the new skin cells move too quickly to the upper layers of the epidermis - within a few days.
The researchers also found genes associated with the development of psoriasis, showing that the disease is inherited, but also the external environmental (physical, chemical, thermal on the skin) and interior factors, stress, unbalanced nutrition, violation of the day and sleep, infection, excessive/regular use of alcohol and smoking) play a role.
Signs and symptoms
Psoriasis is manifested in the form of red or pink squamous cones that merge into large papules (plates) of the skin.Sometimes, when these small dry white stairs combine, a slight bleeding occurs.
There are different types of psoriasis: non -pustling (it affects large areas of the skin) and pustular (rarer shape, usually manifested on the hands or legs).The rash can have various outlines and forms from one point and rocky to a visible monetary.
The first signs of psoriasis increased fatigue, weakness throughout the body, sometimes a slight vertigo, general malaise.As the rashes develop and increase, symptoms such as itching, burning, pain, fever sometimes, chills are developed and increased.
Phases
In the absence of treatment, psoriasis develops quite quickly.In the initial phase, the small pink or reddish scales appear on the skin (which are usually found symmetrically, for example, on both hands the stains will find themselves in the same way).In addition, in addition to reddish points, a squamous surface layer begins to develop.
This is keratinized skin, which is easily removed independently.After the formation of stairs, the reddish points gather in large red plaques, this phase is accompanied by serious itching and burning, as well as peeling of the skin.
Exacerbation
The aggravation phase is characterized by the occurrence of large spots (often swollen) on the skin (plaque, dad), itching serious, burning, often pain.The area of the diffusion of the disease also increases considerably (the plates become diameter of over 10 cm).A peculiar feeling of the skin seal appears.When moving the disease in the exacerbation phase, you need to contact a specialist immediately.During this phase, cracks appear on the skin (due to tension, dryness and keratinization).
Danger to life
During the aggravation phase, the cherathinian dry areas create, the skin begins to bleed and becomes more susceptible to infections, which causes the appearance of new plates (Köbner syndrome).
The most serious consequence of exacerbation can be psoriatic arthritis (the disease will spread to the bones and joints and cause their inflammation and deformation) or psorial erythroder (a very serious incurable skin disease, which can lead to death).
Psoriasis continues to be one of the most complex skin diseases.A wide range of procedures available for the treatment of psoriasis illustrates it.It is very important to adopt measures to retain the disease and prevent it from going to the exacerbation phase, for this it is necessary to ask for help from a specialist, as well as changing your lifestyle, contact medicines and methods of traditional medicine.
