Psoriasis is a chronic skin disease that is caused by the inflammatory of the immune system. In normal skin, the skin cells formed in the deepest layers of the skin before they move to the surface of the skin. After that, it will be replaced with new skin cells from below. The cycle repeats itself and takes about one month. On the contrary, people who are afflicted with psoriasis experience abnormally rapid skin cell cycle. Psoriasis speeds up the skin cell cycle in about four days. Since the skin cell moves to the surface of the skin so fast, the skin cells do not have time to mature. As a result, raised red patches will appear on the skin.
Psoriasis happens when the immune system is accidentally activated; thus it speeds up the skin cell cycle. Plaque psoriasis is the most common type of psoriasis.
Types Of Psoriasis
There are many types of psoriasis. Plaque psoriasis appears a dry, scaly patch on the skin. Guttate psoriasis causes a pink and red drop like patches on the skin. Inverse psoriasis causes smooth red lesions in the armpits and groins. Pustular psoriasis appears as red lesions with white pus filled blisters. Erythrodermic psoriasis covers a large area of the body. It causes redness on the skin and excessive shedding of white scales.
Psoriasis is a common skin condition that affects people in the age of twenties and thirties but may also affect infants. According to research, more than 7 million people in the United States suffer from psoriasis. Psoriasis affects men and women and is most common in the European. Although there are many forms of psoriasis, 80% of the people who are infected with psoriasis suffer from plaque psoriasis. On the elbows and knees, psoriasis appears as thick red patches on the skin. Scalps that are affected with psoriasis tend to have heavy dandruff. If psoriasis infects the nails, the nails may become thickened, discolored, pitted and separated from the nail bed. Stress will make the symptoms of psoriasis worse but vacations will help to improve the condition. Opposite to what is advertised on the television, psoriasis does not cause severe skin itchiness. Psoriasis is not a fatal disease, but if it is spread over a wide area of the skin, it can be disabling, painful and become a deforming type of arthritis.
