Psoriasis is an immune -
inflammatory skin disease. The cause of psoriasis is not fully understood but it
occurs when the immune system trigger the overproduction of new skin cells.
It is typically a lifelong condition,
sometimes inherited and there is no cure.
Psoriasis is a chronic recurring
condition and is not contagious.
The classification includes:
Non-pustular types:
-
plaque, and
-
erythrodermic (redness is very intense and
covers a large area).
Pustular types:
-
guttate (small, drop like spots),
-
inverse (or flexural psoriasis, located in areas which have smooth skin), and
-
pustular (pus-filled, yellowish, small blisters).
The most common form is plaque
psoriasis that appears as elevated, red patches covered with silvery white
layers of dead skin cells. If fingernails and toenails are affected, then it is
called psoriatic nail dystrophy. Psoriasis can cause inflammation of the joints,
which is known as psoriatic arthritis.
Some statistical studies reveal
that psoriasis can also be associated with diabetes, heart disease and
depression.
Because of the dry air, symptoms
of the disease get worse during winter times.
