Psoriasis
Psoriasis means itch in Greek. This skin disorder is
identified by inflation and scaling. Skin cells reproduce faster and
pile up in layers causing scaling. This happens because of an immune
system disorder. Scaling normally occurs on knees, elbows or the scalp.
This may cause loss of hair. It may affect your skin too.
Even though the cause of Psoriasis is not known it is believed
that several factors combine to cause this disease. Some such factors
are
- Genes
- Immune System
- Diet
- Weather
- Stress
- Skin Injury
- Infection
- Drugs
In the regular functioning WBC – White Blood Cells fight
invaders such as virus and bacteria by producing anti bodies. In
Psoriasis affected patients the antibodies also fight skin tissues to
produce chemicals in large amount. These chemicals cause itching and
inflammation in some parts of the body. Researchers hold four types of
Genes responsible for Psoriasis. These genes direct the foreign
invaders to the immune system for destruction. In Psoriasis patients
this system does not work. Even weather is considered to be a major
factor. Cold dry weather can cause Psoriasis and damp hot and sunny
weather can aggravate Psoriasis.

Some scientists discovered that Psoriasis could be caused
by sugar, carbohydrates and acids, fats with uric acid in the diet.
Studies as well as surveys have shown that stress, anger,
anxiety and depression could have a strong association with Psoriasis.
HIV viruses, Streptococcus and such like bacteria can also cause
Psoriasis.
Mild injuries of the skin around elbows or knees may cause
Psoriasis. This is known as koebner phenomenon. Some drugs may also
cause or aggravate Psoriasis. You must consult a doctor before using
such drugs.
