Psoriasis is common and affects about 1 to 5% of all strips worldwide. People with fair skin have an increased risk of psoriasis, while people with darker skin tend to be less likely to develop this disease. Let us dwell more on the topic to explain what psoriasis is, its causes, and symptoms so that we can end up with treatment.
What is psoriasis?
It is a chronic, recurrent disease that leads to the formation of a single, patchy red spot of more than one spot with silver scales and a clear border between the macula and normal skin. For some patients, psoriasis is only a nuisance. As for others, they can cause impotence, especially when they are associated with arthritis.
Causes of psoriasis
Psoriasis is caused by a cause related to the immune system, specifically, a specific type of white blood cell called a T-lymphocyte. Normally, these cells travel throughout the body to find and control foreign substances, such as bacteria and viruses. However, in psoriasis patients, these lymphocytes mistakenly attack healthy skin cells.
More than necessary T-lymphocytes stimulate various reactions in the immune system, such as widening the blood vessels around the skin layers and increasing amounts of other blood cells that can penetrate the skin (the thin outer layer of the skin - Epidermis). As a result of these changes, the body produces more healthy skin cells, more T cells, and other white blood cells.
As a result, new skin cells reach the outermost layer of skin very quickly within a few days, instead of weeks as normal. However, dead skin cells and white blood cells cannot fall off quickly, and so they accumulate in thick cortical layers on the surface of the skin. This process can often be stopped by treatment.
It is not clear exactly what causes T-lymphocyte disorder activity in psoriasis patients, while researchers believe that both genetic and environmental factors play a role.
Psoriasis symptoms vary from person to person, but they may include one or more of the following:
- Red layers on the skin, coated with silvery scales
- Small dots covered with scales (common among children)
- Dry, cracked and sometimes bleeding skin
- Itching, burning or pain
- Thick, thickened nails, cracked or full of scars
- Joint swelling and stiffness.
Layers on the skin, as a result of psoriasis, can appear like a few drops from scales to a rash that covers a large area. Mild cases of psoriasis may be a nuisance, and no more, while more severe cases of psoriasis may cause pain and impotence. Also, most types of psoriasis develop periodically, as the seizure lasts a few weeks or months and then subsides for some time, and may even disappear completely, but in most cases, it returns, in the end, as it was.
Treatment of Psoriasis
Treatments used for psoriasis vary according to their type, severity, and location of appearance. The treatments used can alleviate the symptoms and improve the quality of life. Simple cases can be treated with topical treatments that are applied to the affected area only. It is also possible to use moisturizing creams for the skin that help to Reducing itching and skin peeling, it should be noted that despite the effectiveness of topical treatments for some cases of psoriasis, it needs a period of time for its results to appear up to 6 weeks.
