Psoriasis is a chronic autoimmune skin disease characterized by the rapid proliferation of skin cells, leading to thick, red, scaly patches that can be itchy and painful. These patches, often called plaques, typically appear on the elbows, knees, scalp, and lower back, but they can occur anywhere on the body. The exact cause of psoriasis is unknown, but it involves a combination of genetic predisposition and environmental triggers such as infections, stress, and skin injuries. Unlike some other skin conditions, psoriasis is not contagious. The disease can significantly impact the quality of life, causing discomfort and emotional distress due to its visible nature and chronicity. Treatment options aim to reduce inflammation and slow down the rapid skin cell turnover and include topical treatments, phototherapy, and systemic medications. Managing psoriasis often requires a comprehensive approach, involving lifestyle modifications, stress management, and ongoing medical care to keep the symptoms under control.
