Psoriasis Frequently Asked Questions - Psoriasis FAQ’s
What is psoriasis?
Psoriasis is a recurrent skin condition that affects around 2% of the population. 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 psoriasis 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 womenÕs breasts. Psoriasis, in these areas can look bright red and shiny rather than scaly. Click for more
Is psoriasis catching?
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 people with psoriasis have small patches that either get better spontaneously or need very little treatment. The more severe forms may demand intensive medical and nursing care. Widespread ignorance about the nature of psoriasis and the real or imagined reactions of others may also lead to a withdrawal from society and to feelings of isolation, depression and defensive shyness.
What causes psoriasis?
Certain genes have been identified as being linked to psoriasis. It appears, however, that a genetic tendency needs to be triggered off by such things as injury, throat infection, certain drugs and physical and emotional stress. Research is under way into all aspects of the causes of psoriasis.
What treatments are available for psoriasis?
There are a variety of topical treatments available i.e. creams and ointments that are applied to the skin. When used properly they can be most effective and have minimal side effects. Whatever treatment you use it is also vitally important to use a moisturiser to make the skin more comfortable. Other treatments are available for more serious cases; they will normally mean a referral to a Dermatologist and involve treatment as an out-patient or in-patient. Many people, however, lose the condition naturally for long periods at a time or even entirely. It is important that you, as a patient should feel in control of your treatment regime and it is helpful therefore to talk it over properly with your GP, Consultant or Specialist Nurse.
What is psoriatic arthritis?
Approximately 10% of people with psoriasis develop a specific type of psoriatic arthritis. This is an affliction of the joints particularly at the tips of fingers and toes and occasionally in the lumbar joints causing a low backache. Like psoriasis this form of arthritis can naturally wax and wane.
