What is psoriasis and what does it appear?Psoriasis is the non -infectious state of the skin, the result of which are red flaming plates, as well as dry scales - the result of excessively rapid growth of skin cells.The disease most often affects the skin on the elbows, knees and scalp.
In some people, it manifests itself in a light form, the symptoms are practically absent.Others note serious symptoms, frequent relapses.What comes from psoriasis, where it comes from, why it appears, the causes of appearance, how they are infected - we will try to answer these questions and others on the pages of our portal.
Psoriasis is an incurable long -term (chronic) condition of the skin.Exacerbation steps are quickly replaced by improvement steps.Many patients note the worsening of symptoms from November to February (winter months), as well as in hot summer.Psoriasis affects all ethnic breeds and representatives of both sexes.Although psoriasis may appear in people of all ages - from babies to the elderly - most often, the disease is diagnosed in adolescence under 20 years of age.
At what age does psoriasis appear?The disease is rare in infants (less than 4% of patients), in children, psoriasis can manifest themselves if parents are carrying the disease.Psoriasis in these young children is often preceded by acute pharyngitis, tonsils, bronchitis or respiratory infection, for example, cold, flu or pneumonia.People with psoriasis are more likely to obtain diabetes, hyperlipidemia and heart disease.
Why does psoriasis occur?The causes of psoriasis are unknown at the end, but generally the disease is associated with the problem of the immune system.What and how does psoriasis appear?The key element is a special type of lymphocytes, called T lymphocytes or T cells. In general, 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 wrongly attack healthy skin cells (to fight against a false infection).
Hyperactive lymphocytes cause immune reactions, including expansion and increase in vessels around papules and pustules of pasriasis.These changes lead to an increase in the production of healthy skin cells and other white blood cells.This causes a current cycle, against which new skin cells move too quickly to the upper layers of the epidermis - in a few days.
Researchers have also found genes associated with the development of psoriasis, proving that the disease is inherited, but environmental external factors (physical, chemical, thermal effects on the skin) and internal (stress, unbalanced nutrition, day and sleep violation, infection, excessive / regular consumption of alcohol and smoking) also play a certain role.
Signs and symptoms
Psoriasis manifests itself in the form of red or pink scaly cones which merge into large papules (plates) of the skin.Sometimes, when combing these small dry white scales, light bleeding occurs.
There are several types of psoriasis - non -pustular (affects large areas of the skin) and pustular (rarer shape, generally manifested on the hands or legs).The eruption can have various contours and rock point forms at a monetary-visible point.
The first signs of psoriasis are increased fatigue, weakness throughout the body, sometimes slight dizzy, general discomfort.As rashes develop and increase symptoms such as itching, burn, pain, sometimes fever, chills are added.
Steps
In the absence of treatment, psoriasis develops fairly quickly.At the initial stage, small pink or reddish ladders appear on the skin (which are generally located symmetrically, for example, on both hands, the spots will be located in the same way).In addition, above the reddish spots, a scaly layer begins to develop.
This is keratinized skin, which is easily removed independently.After the formation of ladders, reddish spots come together in large red plates, this step is accompanied by itching and serious burns, as well as skin of the skin.
Exacerbation
The aggravation stage is characterized by the occurrence of large stains (often swollen) on the skin (plate, dad), severe, burning itching, often pain.The propagation area of the disease also increases considerably (the plates become more than 10 cm in diameter).A particular sensation of skin sealing appears.When you move the disease at the exacerbation stage, you must immediately contact a specialist.During this stage, cracks appear on the skin (due to sealing, drought and keratinization).
Danger for life
During the aggravation stage, the dry keratinized areas are cracking, the skin begins to bleed and becomes more sensitive to infections, which causes the appearance of new plates (Köbner syndrome).
The most serious consequence of exacerbation can be psoriatic arthritis (the disease will propagate to bones and joints and cause their inflammation and deformation) or psoriatic erythroderma (a very serious incurable skin disease, which can cause death).
Psoriasis continues to be one of the most complex skin diseases.A wide range of procedures available for the treatment of psoriasis.It is very important to take measures to restrict the disease and prevent it from going to the stage of exacerbation, because it is necessary to request the help of a specialist, as well as to change your lifestyle, to turn to drugs and traditional medicine methods.
