Plaque psoriasis is an autoimmune disease affecting around 8 million Americans. It causes raised red patches with whitish scales, often on the elbows, knees, scalp, and lower back. Plaque psoriasis can itch or hurt, and it’s triggered by factors like stress, sunburn, infections, and certain medications. While there’s no cure, treatments aim to reduce flare-ups and include topical creams, light therapy, and systemic drugs. The condition can be linked to other health issues like Crohn’s disease, diabetes, and psoriatic arthritis. Proper care, including avoiding triggers and maintaining healthy skin, is key to managing plaque psoriasis.
