That itchy feeling: psoriasis
What is psoriasis?
Psoriasis is a recurrent skin condition that affects around 2% of the population in the UK. In simple terms, it is only an acceleration of the usual replacement processes of the skin. Normally a skin cell matures in 21 to 28 days during its passage to the surface where a constant invisible shedding of dead cells, as scales, takes place.
Psoriatic cells, however, are believed to turn over in two to three days and in such profusion that even live cells reach the surface and accumulate with the dead cells in visible layers. Psoriasis affects both sexes equally. It may appear for the first time at any age, although it is more likely to appear between the ages of 11 and 45.
What does it look like?
It appears as raised red patches of skin covered with silvery scales. It can occur on any part of the body although elbows, knees and the scalp are usual sites. There is often accompanying irritation. Some parts of the body do not have this typical scale. These are areas where two skin surfaces come together as in the natural
skin creases and folds e.g. the groin and genital area and underneath women's breasts.

Most definitely not. Psoriasis cannot be caught from other people nor can it be transferred from one part of the body to another. How serious is it? Psoriasis is known as a waxing and waning condition and there may therefore be considerable variations in its intensity. There are also many clinical forms with skin involvement varying from a few psoriatic patches to, at its worst and very rarely, a widespread and serious eruption. Most
