What is psoriasis and what does it appear from?Psoriasis is the non -inferred state of the skin, the result of which is inflamed plaques and dry scales - the result of excessively fast growth of skin cells.The disease most often affects the skin on the elbows, knees and the scalp.
In some people, it manifests itself in a mild form, the symptoms are practical.Others notice severe symptoms, frequent relapses.What is psoriasis where it comes from, why it appears, the causes of appearance, 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.Stages of deterioration are quickly replaced by improvement phases.Many patients notice the deterioration in symptoms from November to February (winter months) and in hot summer.Psoriasis affects all ethnic breeds and representatives of both sexes.Although psoriasis can occur in humans of all ages - from babies to older people - the disease in youth is diagnosed in less than 20 years.
At what age does psoriasis appear?The disease is rare for infants (less than 4% of the sick), in children psoriasis can manifest if parents are wearers of the disease.Psoriasis In such young children, acute pharyngitis, tonsillitis, bronchitis or respiratory infection are often preceded, for example a cold, influenza or pneumonia.People with psoriasis have more opportunities to maintain diabetes, hyperlipidemia and heart disease.
Why does psoriasis occur?The causes of psoriasis are unknown in the end, but usually the disease is associated with the problem of the immune system.What and how do psoriasis appear?The key element is a special type of lymphocytes called T-lymphocytes or T cells.As a rule, these white blood cells move throughout the body to recognize and eliminate foreign substances such as viruses or parasites (streptococcus).In patients with psoriasis, however, T-lymphocytes incorrectly attack healthy skin cells (to combat incorrect infection).
Hyperactive lymphocytes provoke immune reactions, including the expansion and increase of the vessels around the papules and pasis.These changes lead to an increase in production of both healthy skin cells and other white blood cells.This leads to an ongoing cycle against which new skin cells move too quickly into the upper layers of the epidermis in a few days.
The researchers also found genes associated with the development of psoriasis and prove that the disease is inherited, but external factors of the environment (physical, chemical, thermal effect on the skin) and internal (stress, unbalanced nutrition, violation of sleep, sleep, infection, excessive/regular use of alcohol and smoking) play a certain role.
Signs and symptoms
Psoriasis manifests itself in the form of red or pink scaly cones, which merge into large papules (plaques) of the skin.Sometimes slight bleeding occurs when combing these little dry white dandruff.
There are different types of psoriasis - not pustular (affects large areas of the skin) and pustel (rarer shape, usually manifested on the hands or legs).The rash can have different outlines and shapes and rocky and rocky to a monetary visible.
The first signs of psoriasis are increased tiredness, weakness in the body, sometimes a slight dizziness, general discomfort.When the rashes develop and increase, symptoms such as itching, combustion, pain, sometimes fever and chills are added.
Level
Psoriasis develops pretty quickly in the absence of treatment.Small pink or reddish scales appear on the skin (which are usually symmetrical, for example in both hands, the stains are found in the same way).In addition, a scaly surface layer develops on reddish spots.
This is keratized skin that can be easily removed independently.After the formation of scales, reddish spots collect in large red plaques, in this phase there is severe itching and burning and the skin is accompanied.
aggravation
The deterioration stage is characterized by the appearance of large (often swollen) stains on the skin (plaque, daddy), serious itching, burning, often pain.The area of spreading the disease also increases significantly (Plaques have a diameter of more than 10 cm).There is a special feeling of skin tightness.If you move the disease into the deterioration level, you should contact a specialist immediately.In this phase, cracks occur on the skin (due to tightness, drought and keratization).
Danger to live
During the worsening phase that crack the keratized dry areas, the skin begins to bleed and becomes more susceptible to infections, which causes the appearance of new plaques (Köbner syndrome).
The most serious consequence of exacerbation can be psoriatic arthritis (the disease will spread to bones and joints and cause inflammation and deformation) or psoriatic erythroderma (a very severe, incurable skin disease that can lead to death).
Psoriasis is still one of the most complex skin diseases.A wide range of processes for the treatment of psoriasis shows this.It is very important to take measures to contain the disease and prevent them from getting into the deterioration level.This makes it necessary to seek the help of a specialist and change your lifestyle, to contact the drugs and methods of traditional medicine.
