There are various chronic skin diseases. Psoriasis is one of the long-lasting, complex skin condition which is caused by an Overactive Immune System. It causes cells to build up rapidly on the surface of the skin. In Psoriasis condition, inflammation and redness around the scales is more common. Psoriasis is the result of a sped up skin production process.

Generally skin cells grow deep in the skin then slowly rise to the surface and finally it falls off. The typical life cycle of a skin cell is one month but in Psoriasis condition, this production process occurs in just a few days. Because of this rapid process, skin cells don’t have time to fall off. This quick overproduction causes the buildup of skin cells.

In Psoriasis condition, Scales typically develop on joints like elbows and knees. Scales can also develop anywhere on the body including:






Psoriasis rarely affects the nails, mouth and the area around genitals.

Causes of Psoriasis

The causes of Psoriasis are still unknown but the major factors causing Psoriasis are: Genetics and Immune System.

• Immune System

Psoriasis is an autoimmune skin disease. In autoimmune conditions body attacks itself. In a normal body, white blood cells attack and destroy invading bacteria and fight infections but In Psoriasis condition, white blood cells known as T cells mistakenly attack the skin cells. The process of skin cell production becomes faster due to this attack and the sped-up skin cell production causes new skin cells to develop too quickly. These newly generated skin cells collect on the skin surface resulting in the plaques.

• Genetics

This is one of the most significant risk factors. If anyone’s close family member has psoriasis then the risk for developing psoriasis is higher.


Diagnosis of Psoriasis
