Causes of Psoriasis

Though cause of psoriasis is not fully understood, it is considered that disease can occur as a result of an abnormality in the white blood cells. In researches, it is determined that immune system is stimulated by several causes (stress, medication, infection), and this process accelerates the growth of skin cells. Maturation of normal skin cells takes time nearly 28-30 days, but this period can drop to 3-4 days in psoriasis patients. Thus, proliferating cells accumulates on the surface and yields to a thick plaque.

During the disease process, following an inflammation, adesquamation phase occurs. Changes in skin metabolism ¬is a result of disease rather than being a cause. Risk for psoriasis development is increased in some conditions such as; injury, trauma, rheumatic fever, certain diseases with a microorganism ethology. In addition, cancer and immunosuppressant medications, used for the conditions such as; organ transplantation, yield also to an increased risk of psoriasis.

Psychological factors such as stress, tension, lack of love and the mother - child relationship disorders may ensure development or exacerbation of psoriasis. Additionally, hypocalcaemia and hormonal effects are considered to be influential for development of psoriasis.
