Psoriasis: More Than Just a Skin Condition
Psoriasis is a chronic autoimmune disease that primarily affects the skin, but its impact often goes far beyond what is visible. Characterized by red, scaly patches that may itch, crack, or bleed, psoriasis is not contagious, but it can be physically uncomfortable and emotionally distressing.
The condition occurs when the immune system mistakenly speeds up the life cycle of skin cells. Instead of shedding in weeks, skin cells in people with psoriasis regenerate in just days, leading to the accumulation of dead cells on the surface. This overproduction results in the characteristic plaques or lesions seen in the most common form—plaque psoriasis.
Other types of psoriasis include guttate psoriasis, which appears as small, drop-like spots; inverse psoriasis, which occurs in skin folds; pustular psoriasis, which causes white pustules on red skin; and erythrodermic psoriasis, a severe and rare form that can cover the entire body and may require immediate medical attention.
