Psoriasis is a chronic autoimmune skin condition that results in the rapid overproduction of skin cells, leading to the formation of thick, red, scaly patches on the skin. These patches, often referred to as plaques, can be itchy, painful, and aesthetically distressing. Psoriasis is not contagious, and it can affect people of all ages.
Psoriasis can vary greatly among individuals, and what works for one person may not work for another. Early diagnosis and appropriate management can help control symptoms, reduce flares, and improve overall well-being.
Types of Psoriasis:
- Plaque Psoriasis: The most common form, characterized by raised, red plaques covered with silvery-white scales.
- Guttate Psoriasis: Often triggered by a bacterial infection, it appears as small, drop-like lesions on the skin.
- Inverse Psoriasis: Affects skin folds such as the armpits, groin, and under the breasts, causing smooth, red, and inflamed patches.
- Pustular Psoriasis: Involves the formation of pustules (pus-filled bumps) surrounded by red skin. It can be localized or generalized.
- Erythrodermic Psoriasis: A severe and rare form that can cover the entire body with a red, peeling rash. It may lead to serious complications and requires immediate medical attention.
Causes and Triggers:
- The exact cause of psoriasis is not fully understood, but it is believed to involve genetic and immune system factors.
- Psoriasis can be triggered or exacerbated by various factors, including stress, infections (such as streptococcal throat infections), certain medications, injury to the skin (the Koebner phenomenon), and hormonal changes.
