This article provides a detailed overview of psoriasis, covering its types, symptoms, prevalence, and related health conditions. It emphasizes the importance of professional diagnosis and highlights current management options for this chronic condition.

Psoriasis is a chronic autoimmune skin condition characterized by red patches covered with silvery scales. It commonly affects the scalp, elbows, and knees but can also involve nails, trunk, and legs. Less frequently, other areas may be affected. With over 130 million cases worldwide, psoriasis can develop at any age. In the U.S., approximately 7.5 million individuals have plaque psoriasis, making up about 2% of the population. Both genders are equally at risk, with higher rates among Caucasians. Though non-contagious, it is inherited and has no known prevention. It can range from mild to severe and is linked to other health issues like heart disease, diabetes, and joint inflammation. While there is no cure, various treatments help control symptoms. Types include plaque, inverse, erythrodermic, pustular, guttate, and nail psoriasis. Each varies in appearance, severity, and affected areas. Always seek medical advice for proper diagnosis and management.
