Symptoms
There are several types of psoriasis, according to their presentation, but they all have basically the same symptoms. The most common is plaque psoriasis that is characterized by reddish patches with red, rough very thick scaly skin. Itching, peeling and burning are other common symptoms of the condition. Relapses can occur after a period of remission when symptoms can disappear completely, sometimes even for several years.
Usually the rash is located on elbows and knees, but can occur anywhere on the body, including the scalp.
In the case of pustular psoriasis, there are pimples filled with pus mainly on the feet, hands and fingers. As for psoriatic arthritis, symptoms present as joint pain, mainly in the hands.
Causes
The exact cause of psoriasis is unknown. However, there are three factors related to the condition:
- Heredity (40% of cases);
- Physical or psychological stress;
- An immune reaction.
Psoriasis can be caused by an abnormally active immune system that triggers skin inflammation and causes the production of skin cells to increase. The system replaces the skin cells much quicker than normal, in 3 to 5 days rather than 28 to 30 days. This accelerated renewal of the epidermis causes the cells to accumulate on the surface of the skin, forming red, thick patches of skin.
Treatments
To date, there is no cure for psoriasis, but there are treatments that can reduce the symptoms. Most cases are treated with creams and ointments applied directly to the affected area to hydrate the skin and reduce itching. Your pharmacist can direct you to the best treatment for you.
In cases where psoriasis covers a large area of the body, or where the outbreaks are frequent, some doctors may recommend light therapy. The skin is exposed to natural or artificial UV rays that slow the production of skin cells. Follow-up by a doctor is essential.
In more severe cases, medication administered orally, by infusion or by injection can also be prescribed by a doctor.
