Psoriasis

Psoriasis is a chronic, immune-mediated skin disorder that causes the rapid buildup of skin cells, leading to scaling, inflammation, and redness. It often appears as thickened patches of skin with silvery scales, commonly found on the elbows, knees, scalp, and lower back. Psoriasis significantly affects quality of life due to its visible and chronic nature.

• Plaque psoriasis (the most common type)
• Guttate psoriasis (often triggered by infections)
• Inverse psoriasis (in skin folds)
• Pustular psoriasis (with white pustules)
• Erythrodermic psoriasis (severe and widespread)

• Red patches of skin covered with thick, silvery scales
• Dry, cracked skin that may bleed
• Thickened or ridged nails
• Joint pain (in cases of psoriatic arthritis)

Psoriasis develops due to a malfunction in the immune system, where skin cells regenerate too quickly. While the exact cause is unknown, common triggers include:

• Genetic predisposition
• Infections (e.g., streptococcal throat)
• Stress
• Cold, dry weather
• Certain medications (e.g., beta-blockers, lithium)

Psoriasis cannot be completely prevented, but flare-ups can be minimized by:

• Keep skin moisturized.
• Avoid known triggers (such as infections and smoking).
• Follow prescribed treatment plans.
