What is psoriasis? What causes psoriasis? Is there a cure or treatment for psoriasis? Psoriasis is a skin condition, it is a disease, but it is not contagious. The name comes from the Greek word for "itch." It can be hereditary, caused by external influences (allergic reaction to foods or the environment) and sometimes stress. 4-5% of the population is known to be affected, and this number is growing. However, it is suspected that 1 in 5 people have some form of psoriasis either descripts or none descript.
Once you have psoriasis, it is very likely you will have it for ever. It may go away, and come back. It might respond to various treatments, and it may not. Basically psoriasis is your body over producing skin cells. You have too many skin cells in one location which is why it often swells up, becomes dry and even flaky. It can often be very itchy, red, sore, cracked and very tender. Psoriasis usually affects the scalp, hands, stomach, knees, feet and elbows. It is linked to dandruff and unfortunately to some forms of arthritis.
