Causes of Psoriasis
Psoriasis is caused by a problem with the body's defense system, called the immune system, especially involving a type of white blood cell called a T cell. Normally, T cells help protect the body against infection and disease. In the case of psoriasis, T cells are put into action by mistake and become so active that they trigger other immune responses, which lead to inflammation and to rapid turnover of skin cells.
People with psoriasis may notice that there are times when their skin worsens, then improves. Conditions that may cause flareups include:
- Weather changes that dry the skin
- Infections
- Stress
- Certain medicines including lithium and betablockers, which are prescribed for high blood pressure, may trigger an outbreak or worsen the disease
