The name PSORIASIS is derived from a Greek work Psora which mean to itch. Psoriasis is a chronic (long-lasting) autoimmune disease – the body’s immune system is mistakenly reacting to some of your own body’s cells. With normal skin, your body produces new skin cells and sheds the old ones every 28 to 30 dyas. Skin cells affected by psoriasis are produced much faster and are pushed to skin’s surface in about 3 to 4 days, while the dead skin cells on the surface pile up on top of each other instead of falling away on their own The resulting build up forms the dry, scaly, red, itchy patches called plaque. About 1 – 3 % of the population suffers from psoriasis irrespective of age, caste, sex or geographic location.
The exact cause of Psoriasis is still unknown and is one of the biggest challenge in the field of Dermatology. It may or may not be due to one or more of the following – Faulty diets, Stress, Heredity, Psoriasis can also be provoked by external and internal triggers, including mild trauma, sunburn, infections, systemic drugs etc. Researchers think something sets off your immune system. The exact reason is a mystery. But it's likely a combination of genetics and triggers.
1. Your Genes and Your Immune System
Little bits of your DNA, called genes, are instructions for your cells. They control things like your eye and hair color, if you can taste certain things, and other ways your body works. Some genes are only active at certain times.
When you have psoriasis, the genes that control your immune system signals get mixed up.
Instead of protecting your body from invaders as it's designed to do, it promotes inflammation and turns skin cells on overdrive.
Scientists have found about 25 genes that are different in people with psoriasis. They think it takes more than one to cause the disease, and they're looking for the main ones.
About 10 in every 100 people have genes that make them more likely to get psoriasis, but only two or three of them actually do.
2. Hormone Changes
The disease often shows up or flares during puberty. Menopause can also trigger it. During pregnancy, your symptoms may get better or even go away. But after the baby’s born, you might have a flare.
Scientists think your immune system may respond to emotional and mental pressures the same way it does to physical problems like injuries and infections.
Those with a family history of psoriasis have an increased chance of having the disease. Some people carry genes that make them more likely to develop psoriasis. When both parents have psoriasis, their offspring have a 50% chance of developing psoriasis. About one-third of those with psoriasis can recall at least one family member with the disease.
The main objective behind any kind of treatment related with the disease is to stop the skin cells from growing so rapidly as the treatment of psoriasis is still based on controlling the symptoms.
The signs and symptoms of psoriasis can vary depending on the type of psoriasis you have. The 9 most common symptoms of psoriasis include:
1. Scaling of the skin
2. Itchy, painful skin that can crack or bleed
7. Problems with your fingernails and toenails, including discoloration and pitting.
8. Rashes or patches of red
9. Scaly plaques on the scalp

Between 10% and 30% of people with psoriasis also have this painful joint condition.

- Psoriatic arthritis
Plaque psoriasis, or psoriasis vulgaris, is the most common form of psoriasis. An estimated 80 percent Trusted Source of people with psoriasis have plaque psoriasis. It’s characterized by thick red patches of skin, often with a silver or white scaly layer.
