Psoriasis is an inflammatory skin condition. It commonly causes red scaly patches to appear on the skin. In easy terms, it is only an timing of the usual substitute processes of the skin. It may appear for the first time at any age, though it is more possibly to appear between the ages of 11 and 45. The scaly patches caused by psoriasis, known as psoriatic plaques or lesions, are areas of heavy skin production and inflammation.

Though not life-threatening, psoriasis can be painful, effects your ability to function, and cause psychological and emotional distress. The actual cause of psoriasis is unknown, but it is believed that a trigger, such as emotional stress, skin injury, certain infections or a reaction to medication, may set off psoriasis for the first time in genetically susceptible people.

Plaque psoriasis is the most common type of psoriasis and is featurized by red skin covered with silvery scales and inflammation. Psoriasis is autoimmune in pedigree, and is not contagious. About a quarter of people with psoriasis also suffer from psoriatic arthritis, which is similar to rheumatoid arthritis in its effects.

Psoriasis is a chronic, meaning lifelong, condition as there is currently no cure. Occassionally plaque psoriasis can evolve into more severe disease, such as pustular psoriasis or erythrodermic psoriasis. Psoriasis is emanated from the Greek word 'psora', which means itch. Psoriasis can also cause inflammation of the joints, that is known as psoriatic arthritis. Ten to fifteen percent of people with psoriasis have psoriatic arthritis. Some regions of the body do not have this typical scale.

These are areas where two skin surfaces come composed as in the natural skin creases and folds e.g. the groin and genital area and underneath women's breasts. Skin cells routinely die and flake off in scales - but in people with psoriasis this process happens within days rather than weeks. Psoriasis passes in some families, but which is not to say that everyone in a family will get it. Psoriasis may occur on the oral mucosa as well, though it is rare. There are many treatments available but due to f its chronic recurrent nature psoriasis is a challenge to treat.

  • Phototherapy (ultraviolet B, UVB) and photochemotherapy (psoralent ultraviolet A, PUVA) are both used for widespread psoriasis.
