Why Does Psoriasis Spread? This is a common and concerning question for many individuals living with this chronic skin condition. Psoriasis often begins as small, red, scaly patches that can gradually increase in size or appear on new areas of the body. The spread can be influenced by several triggers such as stress, infections, certain medications, skin injuries, and even weather changes. One of the key factors is the immune system's overreaction, where it speeds up the skin cell production process, leading to rapid buildup and scaling. Lifestyle habits like smoking, excessive alcohol consumption, and lack of proper skincare can further accelerate its expansion. Sometimes, what appears to be spreading may also be flare-ups triggered by external irritants or internal health imbalances. People with a genetic predisposition to psoriasis might notice that emotional stress or physical trauma to the skin causes new lesions in previously unaffected areas.
