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

If skin rashes that resemble psoriasis should consult a dermatologist. Psoriatic lesions, which represent the itchy scaly plates of different sizes. While plaque psoriasis may be on the elbows, knees, scalp or other parts of the body. The doctor can accurate diagnosis and depending on its form, to prescribe the treatment.

Causes of psoriasis

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

Currently, psoriasis is considered hereditary diseases: on the basis of the disease is not one but a whole range of reasons – immunologic changes, and metabolic disorders associated with endocrine and neurological disorders. We can say that psoriasis is not contagious, and therefore is not infectious disease.

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

According to one theory, there are two types of psoriasis are:

  • Psoriasis type I, which is necessary for the inherited defect of the immune system. This form of psoriasis affects about 65% of the people, and the disease, which is manifested in his youth, from 18 to 25 years.
  • Psoriasis type II, which occurs in people older than 40 years. With this type of psoriasis is not hereditary and is not associated with defects in cells of the immune system. In addition, in contrast with psoriasis type I prefer skin, psoriasis type II more often affects the nails and joints.

According to the other theory, cause of psoriasis, which are exclusively immunity to interference caused by various factors: it can be stress, or infectious diseases, or cold climate, or poor nutrition. For example, has found that alcohol can cause exacerbation of psoriasis, especially beer, champagne, spirits. Use of products that contain vinegar, pepper, chocolate, also worsens the disease and can cause exacerbation of psoriasis. According to this theory, psoriasis is a systemic disease. This means that in the case of serious violations of the immune system, a process may spread to other organs and tissues, e.g., joints. As a result, may develop psoriatic arthritis, which is characterized by lesions of small joints of the hands and feet.

The symptoms of psoriasis

The symptoms of psoriasis are inflamed, scaly patches of red, along with severe itching. Such patches (plaques) often found on the skin of the scalp knees and elbow joints in the lower back and in places skin folds . About a quarter of the patients, the effect on the nails.

In the period of aggravation of symptoms of psoriasis on the hands, knees, head, and also in the lower part of the back and in places skin folds appear in the form of plates reddish color. Their size may vary from pinhead to large areas of the hands, size and more.

Rashes are usually accompanied by flaking and painful itching. In the process of the peeling of superficial scales are more dense, arranged in the depth (and therefore the other name of psoriasis — psoriasis). Sometimes in the affected areas of the skin appear cracked and fertilizers.

Unfortunately, no one knows, how to treat psoriasis in full, because the body "retains the memory" of the disease in the form of biochemical, immunological and functional changes. Recurrence of psoriasis can occur at any time, so patients with this diagnosis is always to be treated with a dermatologist.

Intake of polyunsaturated fatty acids in sufficient quantities is very important in psoriasis, as they form in the body of biologically active substances (including tissue hormones prostaglandins, act as regulators of biological processes), an anti-inflammatory and antiallergic effect, a positive effect on the skin (as part of cell membranes and blood vessel walls, regulate the metabolism (especially fat metabolism in the liver, in the metabolism of certain vitamins).
  2. Pulp. In this group of patients should be regular maintenance of the cleaning function of the liver and its participation in the exchange. It is very important to regular bowel movements. The tendency to constipation in the diet include products with a high content of dietary fiber and meals with the "laxative" effect (lettuce with vegetable oil, vinaigrette, etc).

  3. Vitamins. Treatment of psoriasis occurs the most successful when careful attention is paid to the intake of vitamins belonging to the group of antioxidants that support healthy skin and nails. They help to neutralize free radicals, skin damage, strengthen the walls of blood vessels, which is important for the synthesis of collagen and elastin (elements of connective tissue). A complex of b vitamins, which are involved in all cellular processes, it also helps to keep the skin in healthy condition. In addition, b vitamins have a beneficial effect on the nervous system, which is important in this disease. Characteristic for psoriasis is an increased proliferation of skin cells and their incomplete maturation. Found that cells in the upper layer of the skin (keratinocytes) have a high sensitivity to vitamin A. currently, in the practice of medicine with success by using vitamin products, which, through receptors on the keratinocytes, leading to greater differentiation and thus try to normalize the development of the epidermis.

When composing a diet, it is important to know the inclusion in the diet of foods rich in vitamin E (vegetable oils), C (rosehip, sweet pepper, currant), And beta-carotene (liver, butter, sweet pepper), (fish products), (beef liver, buckwheat) and bioflavonoid (currants).

In psoriasis the skin becomes dry and rough, Horny layer of the epidermis is greatly thickened. Violation of cellular processes leads to the fact that the skin is more difficult to retain moisture, it undergoes dehydration. Therefore for psoriasis are advised to use emollients, which make the skin more soft.

How to change the properties of the skin affect psoriasis?

For the affected skin with psoriasis, is characterized by the accelerated renovation of the epidermis. The norm for a full update of epidermal cells takes 3-4 weeks, but in psoriasis it takes only 4-7 days. Due to dehydration skin becomes dry and less elastic. In addition, it becomes susceptible to inflammation, so panels that appear on different parts of the body, especially on hands, feet, torso and scalp have a reddish color. Usually plaques covered with thin whitish scales. Psoriasis is a chronic disease, which occurs usually after 15 years.
