Psoriasis is a chronic immune-related condition that primarily affects the skin, though it can also influence overall well-being. It occurs when the immune system accelerates the skin cell growth cycle, causing cells to build up rapidly on the surface. This leads to thick, inflamed patches that may itch or feel uncomfortable. The most common type, plaque psoriasis, appears as raised red areas covered with silvery scales, often on the scalp, elbows, knees, or lower back. Symptoms tend to flare and subside in cycles, making consistent management important.
Other forms include guttate psoriasis, which appears as small drop-shaped spots, pustular psoriasis with fluid-filled bumps, inverse psoriasis in skin folds, and the rare but serious erythrodermic psoriasis. The condition is not contagious; it stems from genetic and environmental factors such as stress or infections. Treatments range from topical creams to light therapy and targeted medications. With proper care and healthy lifestyle habits, many people successfully manage psoriasis and maintain active lives.
