Psoriasis is a common skin condition which generally affects people between 15-35 years of age. It is non-contagious but chronic skin disease in which there is rapid growth of new skin cells, which generally takes time. Thus, thick patches of red, dry and itchy skin appear because of accumulation of dead skin cells.
These dry patches can develop around elbows, knees or scalp and in most cases go unnoticed. However, in some cases, the condition can be severe in which a large part of the body is affected.
Causes:
The exact causes of the disease are still unknown. However, experts believe that genetic conditions and immune system can contribute to the disease in some way. In psoriasis, healthy skin cells are attacked by the body’s T-cells, thus triggering rapid production of new skin cells. Causes believed to influence the disease are as follows:
- Stress
- Obesity
- Smoking
- Climate
- Low immunity
- Use of certain medication
There is no complete cure for the disease. However, preventive care and treatment can help the patient get relief from inflammation and skin irritations.
