Causes and Types of Psoriasis
Throughout the world millions of individuals suffer from Psoriasis. This chronic disease affects our immune system. Thick red patches appear on the skin. Nearly 30 percent of psoriasis patients also suffer from psoriatic arthritis.
Causes of Psoriasis
Psoriasis is an autoimmune disease, which occurs when our immune system sends wrong signals that increase the growth cycle of our skin cells. It can occur on any portion of our body. Psoriasis is often linked to other health conditions, such as, diabetes, depression or cardiac ailments.
Types of Psoriasis
Generally, people suffer from a single type of psoriasis, but occasionally one might suffer from two or more type of this disease. It is also found that the type of psoriasis changes from one form to another. After you get rid of one type of psoriasis, another type of psoriasis might appear.
Plague Psoriasis
Plague Psoriasis occurs in 80 percent of psoriasis sufferers. It largely appears on the knees, elbows, lower back and scalp, in the form of red raised swollen lesions covered with white silvery scale.
Guttate Psoriasis
The small red lesions often occur during childhood or early adulthood. The small red spots are not as thick as the plague psoriasis lesions. They appear on the limbs and trunk. Guttate psoriasis often results from upper respiratory infections, tonsillitis, streptococcal infection of the throat, skin injury, stress and side effects of anti-malarial and beta-blocker medications.
Inverse Psoriasis
These lesions appear in the skin folds, such as the armpits, groin, around genital, under the breast and the buttock. They are deep red in color and are smooth, lacking scales.
Pustular Psoriasis
It occurs as pus filled white blisters surrounded by red skin. This form of psoriasis occurs allover the body or may be localized. Pustular psoriasis may be caused by certain topical medications, exposure to UV light, infections, stress, systemic steroids or sudden withdrawal of systemic steroids.
Erythrodermic Psoriasis
It occurs as intense redness spread across a large area. It is accompanied by itching and pain. If left untreated, the protein and fluid loss from the flare up can cause severe ailments.
