1. What is psoriasis?

Psoriasis is a condition of the skin characterized by itchy rashes which appear and disappear on its own, anywhere on the body.

2. How does psoriasis occur?

There is no exact cause of psoriasis but it’s known to be an autoimmune condition.There is inflammation in the skin which causes increased production of the skin cells.Normally, new skin cells are produced and replaced at a constant rate, in about 10-30 days.
Psoriasis causes increased skin production leading to accelerated turnover of cells every 3-4 days.

3. What is the age group and other predilections to get psoriatic patches?

Psoriasis often develops between the ages of 15 to 35, but it can occur at any age. About 10 to 15 percent of those with psoriasis get it before age 10.
Some infants have psoriasis, although this is a rare scenario .
Men and women develop psoriasis at equal rates.

4. Is it a genetic or hereditary problem?

At least 10 percent of the general population inherits one or more of the genes that create a predisposition to psoriasis.
