Psoriasis is a chronic condition where the immune system overworks, causing rapid skin cell growth. This leads to flaky, red patches, often on the scalp, elbows, or knees, though it can affect any area. Symptoms can flare up for weeks or months, then subside. “People who have psoriasis have a chronic disease in which the immune system overworks, making skin cells divide too quickly.”

While the exact cause remains unclear, genetics and environmental triggers, such as infections, stress, and medications, play a role. Psoriasis can affect anyone but is more common in adults. Types include plaque psoriasis (most common), guttate, pustular, inverse, and erythrodermic psoriasis.

Treatments range from creams for mild cases to pills, injections, or light therapy for severe cases. Managing triggers like stress is also crucial. Psoriasis is linked to conditions like psoriatic arthritis, heart disease, and mental health challenges. Consult a doctor for persistent symptoms.
